Launch HN: Lofty AI (YC S19) – Real estate investment with alternative data
81 points by loftyai 11 days ago | hide | past | web | favorite | 106 comments
Hi Hacker News Community,

My name is Jerry, and I’m one co-founders for Lofty AI (https://www.lofty.ai/). We use machine learning to help identify homes where values are likely to appreciate, and we help home buyers buy them. People can partner up with us to buy a recommended property. If they do, we are willing to cover any potential losses on the property. In exchange, the buyer agrees to share some of the future profit on the home with us. The agreement lasts 3 years.

Before starting this company, my co-founder and I had tried to invest in homes. However, we quickly got tired of realtors telling us to make offers based on very little data. We wanted to figure out a way to buy affordable homes that had the highest growth potential via a data driven approach. We realized there was a wealth of new alternative data out there, which could be used to predict both neighborhood growth and individual property growth. This alternative data we envisioned ranged from the growth in the number of postings on social media about a specific dog breed, to the number of restaurants in an area serving a specific type of trendy food, to the average wait time for ride sharing apps, and the average maximum temperature an area can experience.

Our tech involves running clustering to identify trends and keywords from text based data (e.g.: social media photo tags, business reviews) that are associated with different categories of neighborhoods (for example: rich/suburban/static, middle-class/urban/growing). We then take these insights and feed them into a larger model with historical home prices, house level features, and an array of other numeric features (e.g. ride sharing wait times, new businesses) that predicts future home price on both an individual property and neighborhood level. With this trained model we can then predict future home prices based on these alternative data sources (as well a few traditional data sources). As we ingest more data going forward we are constantly retraining and reoptimizing our models. Along with successful backtesting we have been tracking our predictions to validate our models in production and have found that properties we had identified 12 months ago have beaten the market in appreciation by an average of 14 points (yay!).

Most young working professionals want to live in or near large metropolitan cities for the lifestyle and better jobs market. This has contributed to extremely high home prices for places like the bay area and many young professionals end up paying rent that is on par with a mortgage payment. However, instead of building equity in their own future through an investment, they are simply making their landlords richer.

We want to change this by giving people another option. They can now invest in a home and their capital can be protected should the investment flop. The trade off is that these homes tend to be located in areas not “currently” deemed to be a desirable neighborhood. In essence, we want to help inexperienced home buyers make smarter decisions, and we are willing to risk our own capital for that. In the event of a downturn in the market we are hedging our exposure by buying deep out of the money options that track the real estate market. These hedges are also attached to each individual contract so even if we were to go out of business before the maturation of the agreement or before a downturn in the market your downside protection would still be alive and well! As a result, anything that’s above a 20% decline across the portfolio will be covered by the hedging instruments, so we only need to be able to guarantee the range between 0 to -20% using our own capital. To make sure we can abide by the guarantee, we know exactly how many contracts we can enter into, and we will not go above that threshold until we obtain more funding.

Sign up with us to receive a list of recommended properties that our models think will appreciate over the next 3 years. Make an offer on the property you like the most using any method you’d like. If you don’t have an agent you work with, we can recommend you one along with helping you get a mortgage. After you make an offer on a home, you enter into a contract with us. We agree to cover losses over the next 3 years and in exchange, you share some of the future upside with us.

Let us know if you have any questions or insights, and I’ll be happy to respond! Feel free to directly reach out to me at jerry@lofty.ai as well. We’d love to hear your feedback and suggestions!


Very cool. I just forwarded to a friend looking to buy. As a real estate investor, I can see why this would benefit a lot of people. I personally buy from a handful of turnkey operators (Midsouth Homebuyers has a 3 month vacancy guarantee), but may consider this in the future.

I'll start by saying that I assume you know much more about the market than me, given that you've started this company and made it into YC.

If I read your post right -- the way your insurance works is:

I'm a home buyer. I think the housing market is frothy right now, but I want to buy a home anyway. So I can use your insurance to protect myself in the event the value of my house decreases in the future.

Your company is directly responsible for the first 20% decline. After that, other companies are responsible for the rest. And even if you go out of business, I'm still covered by those other companies.

Firstly, is that correct?

Secondly, if so -- what happens if you go out of business and my house goes down exactly 20%? I assume that means I have no coverage.

Thirdly, who's insuring the houses after a 20% decline? And why should I have any reason to believe they'd still be in business if the market collapses 20%+? The last time that happened, almost every insurance company and investment bank went out of business.

Finally, how much does this cost as a percentage of the house's current value yearly? Roughly...

It's an interesting idea. Despite the fact that most home buyers anticipate house price appreciation to underperform historical averages (and a lot of buyers actually think prices will go down) -- a lot of houses are being bought. I think a lot of those people would want an option like this.

Thanks for your question!

I believe my main post or the responses might have been unclear. If so, my apologies.

But your understanding isn't correct. Other companies are not insuring your downside. We are the only counter party you have.

The problem is if a recession happens, then a lot of our properties actually decline in value. As a result, we might not be able to pay you back. So to make sure we can pay you back we buy financial instruments on the open market, kind of like buying a stock of apple for example. These instruments work in a very interesting way. Their prices go up, if the real estate market goes down. Their prices go down, if the real estate market goes up.

So, with these instruments. We can ensure that in the event of a recession, we can still afford to pay you back, because we can sell the instruments for higher prices than we originally paid for. We then use that profit to cover the losses our customers experience.

The way this works out is that events that would cause large declines in the property values are covered by these instruments. Which means, as a company, we just need to pay specific attention to the potential losses between 0-20% range. Here, we deposit the 20% value of the original purchase price into the 3rd party account.

In the event that our company stops operation. These hedging instruments don't expire or disappear. They are bought at the beginning of our agreement with our customer. As a result, these instruments will be passed off to our lawyers along with the 3rd party account for them to maintain. This way, your loss coverage will still be guaranteed even if we go out of business.

Is this more clear? If not, I can always elaborate :)

> The problem is if a recession happens, then a lot of our properties actually decline in value.

So, you've hedged against a broad real-estate market decline, but you aren't just making broad, representative real-estate market investments, you are investing in properties selected by the combination of your algorithm and customer choices. There is no guarantee that the subset of the properties selected by your algorithm that also appeal to buyers interested in your product will perform as well as the general market (your algorithm could turn out to suck[0], your customers could simply happen to select the worst of your algorithm’s recommendations, or an unpredictable event could occur which negatively impact values in a subset of the market which just happens to disproportionately correlate with the properties your customers selected.)

[0] And, sure, you think it doesn't, but the problem with any ML algorithm that is supposed to outsmart the market is that the market is full of people using tools like that to try to outsmart the market.

He was talking about a recession. Which might happen. (since people feel like it is getting closer)

If you know a stock which actually goes up in a recession, please let me know!

Buy put or sell calls on an asset that's highly correlated with the overall economy. This is honestly the least controversial claim the OP is making.

Correlations change. You never know if gold might tank along with assets in the next recession. Or if yields will tank along with assets in the next recession. What if there's just hyper inflation?

No one knows what's going to happen...

You can go with Dalio's claim that as long as you have 10 hedges that are sufficiently un-correlated, your risk is incredibly low. But even that might not hold up under future unknown conditions.

You're absolutely right about the correlation changes. However, gold's correlation to the general market was developed organically by human behavior over time. That does often change during crisis.

However, options contracts are a form of derivatives, meaning they are contracts financially engineered to hold a specific correlation. So, you can build perfect hedges using options contracts, which is what they were originally invented for. People just started betting on the markets with them, which created all kinds of risks in the market.

There is no such thing as a perfect hedge. Delta hedging is not perfect and cannot be done continually.

Haha it's not really about the stock itself. It's about how you bet in the market. If you truly believe that the market will fall, you can short sell and index fund or purchase some put options on that index. If the market does fall, you will make money as a result.

You just need to make sure the instrument you are betting against is representative of the overall market.

Okay... but who issues the instruments? I mean, what happened to instruments sold by Bear Sterns when they were acquired?

And what instruments are you actually buying? Are there put and call options for CoreLogic Case-Shiller???

Many large market makers issue these instruments.

They are not traded OTC and thus would not face liquidity problems like the OTC instruments people couldn't offload during the GFC (specifically like those guys in the Big Short).

As far as what the instruments actually are: they are puts on broader market REITs/ETFs as well as localized ones. We cannot name the specific instruments as we do not want their prices being bid up.

Hope this clarifies and of course happy to answer any more questions you may have!


That's more clear.

What happens if the house goes down 25%? I have coverage on the first 20%, and then I'm liable for the other 5%?

Any loss above 20% will be covered by the options purchased at the inception of the contract that go up in price if the real estate market suffers a larger drop (>20%).

So we personally guarantee up to a 20% drop with our own capital and use financial instruments to hedge any drop greater than 20% so as to make you whole regardless of the size of the drop.

Thanks, that's much more clear. I'm still confused about how you make that guarantee on the first 20%. You keep it in reserve?

Edit: generally, I wonder if you have a huge perception problem even if you've designed a responsible insurance product due to the fact that people are (reasonably) suspicious of taking on enormous amounts of counter-party risk from a pre-seed start-up.

Yep! That's exactly right. We keep that in reserve in a 3rd party account :)

Also, you have a great point on the perception problem, which is what we are trying to tackle right now. We have genuinely designed a product that is meant to be the most customer-friendly buyer model out there, but because we are a seed-stage company, many people are just concerned, because we lack a long standing reputation in the industry.

> As a result, we might not be able to pay you back

This is an absolute non-starter.

Sorry to be blunt, guys, but if you can't cover your promises, they aren't promises.

Your customers should be nuts to agree with this. Or misinformed. Again, sorry, I don't want to bash you, but what you are offering is simply too bad for your customers.

And then it goes on to say:

to make sure we can pay you back we buy financial instruments on the open market, kind of like buying a stock of apple for example. These instruments work in a very interesting way. Their prices go up, if the real estate market goes down. Their prices go down, if the real estate market goes up.

So, with these instruments. We can ensure that in the event of a recession, we can still afford to pay you back

> Their prices go up, if the real estate market goes down.

Hopefully they provide more detail here.

I'm old enough to remember 2008 and recall many financial instruments with a traditionally inverse correlation to each other behaving unexpectedly. Similar unexpected behavior led to the LTCM crisis in 1998.

My father -- born in 1922, grew up in The Great Depression -- always said "The best way to double your money is fold it in half and stick it in your pocket."

There are no guarantees in life (except maybe death and taxes). They seem to be taking reasonable precautions. They don't deserve to be lambasted for being a bit green and failing to phrase their comment like smarmy con artists pretending there is zero risk -- just trust me (wide, toothy grin).

Thanks for the kind words Doreen, your father sounds like a wise man :)

We have tried to engineer the agreement to the point where only during times of nuclear war or some crazy natural disaster, would we not be able to cover the losses.

And per our contract, we are not liable for these act of god events. So, we recommend all of our customers to purchase insurance on property, especially if they live in risky areas related to weather phenomenons.

Down the line, our priority is to incorporate climate modeling , so that we just no longer recommend properties prone to natural disaster damages.

You're correct in that many financial instruments with traditionally inverse correlation started moving differently. However, this is mainly from the natural correlation between two instruments that may develop over time.

For example, assuming the cell phone market only had 2 players, apple and samsung. And let's assume investors think it's a winner takes all market. So, historically, if apple shares went up, it means investors think they will dominate, which means investors think samsung will lose. This may lead samsung stock to decline when apple stocks increase and vice-versa.

Now imagine a recession. Investors don't care about that relationship anymore, because they just want to pull their money out of the market. Now everyone is dumping both apple and sumsung, so now, the correlation has changed.

I assume this is what you are talking about for the instruments you were mentioning. But, we use options, which are artificially created, so when we buy put options, they will always be 100% inversely correlated to the underlying REIT/ETF. Therefore, if the REIT/ETF goes down during a recession, our options will increase in price.

Hope this clarifies things!

Sorry that the post wasn't as clear. My intention with that line was to walk people through the process step by step.

Of course, we engineer the product so that we can pay people back. But I wanted to show people our thought process, which is what happens if there was a recession and most of our portfolio declines by more than 20%. If we didn't have hedging instruments, we wouldn't be able to pay people back.

Therefore, our next step was to purchase hedging instruments for every contract we take part in. Hope this clarifies things. If not, let me know, and I'll be happy to elaborate more.

Are each contract's hedging instruments independently hedged some how? I read that you invest in markets that "go up" if housing goes down, but let's take the 2008 financial crisis how do you defend against a rolling collapse? Are the markets you're betting in truly independent from each other? How much failure in the markets can you weather? Copious amounts of secret sauce?

Seems like an awesome idea in principle...

my guess is that they're buying put options on the shiller home-price index, at a strike price 20% below the spot price.

though, those indices are only granular at the city level, whereas during a recession all neighborhoods in a city don't drop in value by the same rate - eg for bay area in 2008, east bay got decimated, whereas palo alto/peninsula barely dropped 5%.

You're getting warmer ;)

We also don't just hedge with options on 1 index, so a blend of hedging instruments can get us pretty close to 100% granularity. Any percentage points that are not covered in a granular manner should be offset by performing contracts, and the worst case is we use our own capital to cover maybe the remaining 1-2% uncovered risk.

Do you have any type of financial insurance to backup of your claim that you will cover losses if the property sells for less? I'm not talking about having the money available to cover the losses, but actually being around at all to honor that claim.

What happens if I buy today and your company goes to hell in two years? How can I trust this transaction with a horizon of 3 years without fully knowing how are you going to perform as a company.

Of course, if you disappear and I don't have to honor the 20% it's a win for me, but if I buy based on your data and after 3 years the property value is way down and you're not around to honor your loss-covering promise then I'm fucked. I bought a house because you told me it was going to appreciate, but it didn't. Now what? Do you have a way to pay me back even if your company is not around anymore?

There's something about the model that doesn't make sense to me.

Great question! So, we actually maintain a 3rd party account that is only allowed to invest in short-term US treasury notes.

We track all the properties in our portfolio daily. Any on paper depreciation will result in us depositing funds into the 3rd party account. Whenever a property price moves above the original purchase price on paper, we will withdraw any previously deposited fund. This on-going process along with the hedging instruments are what allows us to guarantee the downside protection.

As a final layer of protection, we know exactly what our on going exposure is, so we know the maximum amount of contracts we can underwrite. We are very strict on this number and will never move above it. So, even if our company ceases operations, all of the downside protection will still be available to our customers.

Keep in mind, we also know exactly what our on going

> So, even if our company ceases operations, all of the downside protection will still be available to our customers.

Can you expound on this a bit? If you go under, who would I have to go to get paid? What legal guarantees would I have in place assuring me the payout? How do I know that your underwriting scheme is sufficient for covering your exposure?

Per the operational parts of your question, it will be our lawyers who would be maintaining the 3rd party account and making sure the money gets sent to people who are owed the loss coverage.

In terms of our our underwriting process works. We do have clauses in our contract that removes our liability for act of god events, civil strife, or war. Barring these scenarios, the only other events that can move a property's depreciation to more than 20% is a recession scenario, which the hedging instruments would cover.

So, in reality, our exposure for every home is between 0 to -20%. So for every home we underwrite, we just need to mark funds equal to 20% of the property value.

Is this clear? If not, I'm happy to expand on it further?

> We track all the properties in our portfolio daily. Any on paper depreciation will result in us depositing funds into the 3rd party account. Whenever a property price moves above the original purchase price on paper, we will withdraw any previously deposited fund. This on-going process along with the hedging instruments are what allows us to guarantee the downside protection.

So how does it work if your system values a property above what it's actually able to sell for? It sounds like so long as you value the property at or above the initial purchase price, there is $0 set aside to pay out any loss of value claims. If the owner sells into a falling market, and needs to sell for less than the initial price how can you pay out? Why wouldnt they just take any price they can get if they have 100% downside protection?

Moreso - if the overall housing market is falling, how does the business survive if all of your customers sell at a loss? I can't think why someone wouldn't sell if they have 100% downside protection and can then move into a cheaper home.

Great question! In our agreement, we set the initial sales price for the customer. However, for every 30 days it does not sell on the open market, they can lower the price by up to 5% until it sells. So, if it ultimately sells for a loss as a result, we would still provide the loss protection.

In the event that a customer wants to buy us out after 3 years. The rate used to calculate change in on paper value is derived from the median home price rate of change from that neighborhood. The value comes from the MLS and it's a rate that neither we as a company nor our customer can artificially manipulate. So, we think it's the best representation of the market change.

If the overall house market is falling, our hedging instruments will provide us enough revenue to offset our customer's losses. If it's not a market wide recession, the gains from some contracts should very easily offset some of the losses along with our own capital we use to guarantee the loss.

These methods combined should allow us to guarantee the losses in all different market scenarios.

I understand the money part. My question is purely operational. Who is going to write me a check if Lofty AI, Inc. disappears? Do you have a contract with the 3rd party to do that?

Ah got it! Sorry for the misunderstanding. Essentially in the case of our demise, our investors are not able to claw back the money in the 3rd party account. The rights will transfer over to our law firm to maintain kind of like an estate. They will be the ones to handle the operation of writing checks and sending funds to the correct counter parties down the line.

My first reaction was: If this company goes under (like 90% of YC startups) and you took this sort of arrangement, then you are @#$!'d (all caps).

Hopefully my other reply answered your concern as well. If not, let me know, and I'll be happy to go into more detail.

Well over 50% of YC startups across all batches have either exited or are still alive.

Wow! I knew it wasn't as high as 90% death rate, but 50% survival rate is actually quite high!

For years the simplest heuristic I can find for finding up-and-coming places has been "Where is Starbucks opening new stores?" I assume Lofty's is much more complicated than that, but I'd be curious to see what the overlap is between the Starbucks Strategy (TM) and Lofty AI's.

I do have a few more questions though:

- Also, are you focusing on primary residences, homes as investments (i.e., rentals)? Do you consider apartments, duplexes, or commercial real state?

- Do you have an idea of how long one would have to own these homes for the appreciation to appreciate in a significant enough way for it to be profitable?

- You mention "some of the future profit". How much is that? 1%, 5%, 10%, 50%?

Great question! The Starbucks Strategy is actually well known in the industry. Believe or not, large real estate developers and investors will often follow the same signals. They also look for things like Trader Joe's or Whole Foods opening.

Our algorithm is very similar in concept to this strategy. However, by the time Starbucks or Trader Joe's opens in an area, it's often towards the middle or late stages of a neighborhood's growth. We can find amenities that are even earlier indicators than Starbucks. Think your one-off local coffee shop named "Bob's coffee" or something similar.

We are focused on the appreciation potential of residential real estate, which has single family houses, condos, and town homes. However, we have noticed that in areas where home prices are growing, rents typically are growing as well. So our customers are welcome to rent out the properties for cash-flow.

We do not have data on a lot of commercial properties, but we can still underwrite the agreement on duplexes and smaller multifamily units.

It typically takes 3-5 years on average for neighborhoods to see the exponential portion of their growth curve, so our agreement is for 3 years by default.

Our share of the profit is 20% of the gross profit. So, if you had bought something for 100,000 and you sold it for 200,000 in 3 years. Then, we would get 20% of the gross profit ($100,000), which would be $20,000.

edit: made numbers in example more clear.

Is this share of the profit based on actual profit after sale or the valuation after 3 years?

From my limited research, property flipping every few years isn't a great idea because of how much is lost in the actual buying and selling process e.g. realtor fees.

Our customers have 2 options. They can choose to sell, at which point, the 20% is based on gross profit realized.

Or they can choose to buy us out. At which point the 20% is based on the "on paper appreciation" calculated by using the rate of change for the median home price in their neighborhood.

If they use the latter option, they of course, will not have to pay the fees associated with a sale.

We are also looking into whether we can partner with listing agents, who will share some of the commission with us, which we will then refund back to our customer to offset their fees.

Excellent answers. Thanks!

according to the site, you keep 80% of the profit, so their cut is 20%.

You keep 80% of the GROSS profit, so if there were $10k in closing costs, and $5-10k/year in taxes/HOA/condo fees, and the furnace and AC need replacing, etc...

Lofty makes this sound risk-free but it certainly sounds possible that your obligation to them would cancel out your entire NET profit. Buyer beware, as always.

Your point is very valid. Closing costs and other fees related to real estate transactions are something we do not cover at the moment.

Our belief is that there shouldn't even be all these fees for home buyers and sellers, because most of the process can be automated to a degree. At a minimal the fees can be reduced. It's early now, but we really do intend on becoming the most honest and transparent ibuyer model on the market.

As such, we are looking for ways where we could build on top of our service to help people reduce their transaction fees either through partnerships or some new service that we would provide. Partnering with listing agents, where they give us a portion of the commission, and we refund it back to the customer is one way of doing this.

But the goal is always to align our interests with our clients'. The more money you make, the more money we make. If you make no money, we not only make no money, but we might lose money.

This is a good point. What if one spends $20,000 fixing up a property, and that contributes to what is ultimately a $50,000 increase in appraisal value?

EDIT: There is an existing response from another comment thread:

>That's a great point! This is why we deduct any home improvement costs from the gross profit calculation. So, if you spent 10,000 fixing the pipes and the gross profit was originally 100,000, we would actually deduct that from the gross profit. So our 20% share would be on top of 90,000 and not 100,000.

Haha thanks, you beat me to it! :)

Why did you decide on this business model (essentially downside insurance paid for by equity if I'm understanding it right) over something simpler like, say, subscription access to a newsletter?

What's to stop someone from signing up for the list and just buying a property on their own? (i.e. What perks are you offering that make it worth doing the deal through you? Negotiations? Acting as a buyer's agent?)

As a data point, I used to have a ruby script that would take a bunch of MLS IDs and go pull a ton of facts from Zillow and a few other sources. I would have my realtor set up a high-level search (i.e. SFH in these areas under $500k) and then take their daily emails and run them through my script to identify potentially "undervalued" properties. I still had to hand-check them after, but it was a pretty useful second filter (the MLS search being the first).

Thanks for your question! We decided to do this model, because we originally sold our predictions and analytics to larger investment funds, but we noticed that when our predictions came true, we left so much money on the table. The funds were making millions of dollars on one deal and they were never going to give us any percentage of that.

It was also really hard to convince a lot of these people who were operating on "gut feelings". In January of this year, we made the prediction that Compton, LA was going to see an increase in growth. We told these bigger funds and they literally laughed at us during the meeting. Fast forward to today, and some of the properties in the micro-neighborhood we forecasted showed an 18% growth in price in just 7 months.

So we decided that consumers might find what we are building to be more valuable, and they would be more open to sharing the profit with us if our predictions came true.

Our added benefit is really finding neighborhoods that people overlook, but have high growth potential. Realistically, without our platform, I would have never known about the growth or be interested in Compton, LA either.

Right now, there is a paywall to view the listings. It's $100/month, but you may cancel at any point. Additionally, if you end up signing a contract with us, we refund you all the money you've paid up to that point. If people do not do the contract with us, then they would also not be offered the downside protection.

I love hearing about people's own unique technical method for finding properties! Were you able to invest in any properties using your method?

I did. We were out-of-towners at the time, so I would use that to build a strike list of 10-20 properties. We would fly in and do as many visits as we could schedule in a weekend.

Currently at 8 doors (that SFH, a tri, a quad), but now that we live in the area I typically just run one or two at a time in a spreadsheet instead of cranking through 100 in one go.

I find the list much more interesting than the insurance (I'm a big boy who can do my own risk evaluation). I only invest in one market, though (Atlanta), so not sure I would pay $100 for a nationwide list.

How do your internal valuations compare to the Zestimates? Zillow's data is better than nothing, but I know a lot of folks track their net worth through things like Mint/Personal Capital who might be interested in a more accurate daily/weekly/monthly valuation tool. I feel like that's how Zillow got their initial users ("You can look up the price of any house!") and if you could figure out a way to expose that data you might be able to get good leads out of it.

Totally understandable that $100/month may be steep for a nationwide list when you would only want Atlanta. We do plan to add a cheaper tier where you can select just one or a few cities.

As far as having a Zestimate like tool - most of our models have focused on predicting future appreciation. That being said, our instantaneous pricing tool often gives similar estimates to Zestimate but differs from Zestimates a decent amount of the time. I know Zestimate reports having quite a high accuracy but anecdotally it can be way off, especially when comparing the Zestimate for a property to what it ends up being listed and sold for. Part of that is i think is, as you mentioned, there data is better than nothing. We have recently begun tracking our internal instantaneous pricing estimate VS zestimates for properties before they go on the market and comparing who was closer to the sale price so that will be interesting to see.

Appreciate the feedback though as we are looking for the best balance between sharing insights and data and protecting it so as to generate the strongest leads with the highest conversion rate.

You should track your internal estimates against Redfin instead/also. They tend to be more accurate, at least in the Bay Area.

That's interesting, we'll take a look. Thanks for the suggestion!

This is the first time I have ever seen an early stage company include Saint Louis in anything, so, thanks for that ;-).

That said, you say your market is:

"Lofty AI is best for people who are: 1. Thinking of buying their first home, but are nervous about losing money. 2. Looking for higher returns than normal by buying properties in an appreciating neighborhood early."

1. I wonder if people who know they have to sell in the next three years, but don't want to sell today (e.g. a work move) are also a target market. If I know my job is going to move me in 2 years, I might like to use your service to retain 80% of the upside, but insure against downside when I sell.

2. I once read a book about real-estate investing, which said that the real way you make money is to buy rental properties with poor cash flow, 'fixup' the tenants to improve the cash flow, and then sell, repeatedly. I wonder if your appreciation-potential-evaluation/downside-insurance model applied to rental properties for sale, combined with coaching/tools for aspiring landlords, might be attractive.

It seems like right now, you are primarily using the purchaser as a source of capital, and other comments are saying "why don't you just raise the money yourself?", but if you were also using the purchaser as more like a franchisee, someone who is actively working to improve the cashflow of the property by upgrading the tenants with your (automated) advice, that might create a more interesting relationship where you have more room to add value (its more complex to analyze multi-tenant rentals, its more complex to choose high-potential landlord partners, etc).

Random thoughts. It's a very interesting idea, very original.

Thanks for the feedback, you bring up some really interesting points.

1. I think what you're saying (and please correct me if i'm wrong) is that we could go after people who aren't about to buy a home but who already own a home and may want to sell it in 2-3 years. That is actually something we already have done and are open to doing more! We could certainly make it more explicit on our website that this is an option.

2. This is a really cool concept. As you have noted we aren't so much in the business of encouraging people to optimize the cash flow on a home and partnering with them on that, but this is a common way to make money of real estate and is certainly something we could branch out into.

This would complement our goal of not having to just become a fund and help solve real pain points people have in purchasing homes really well.

Again, really appreciate this feedback - the phrasing sparked some really cool insight and will definitely think about this more going forward.

Do you have any customer testimonials? It would be good to link to them.

This is definitely something I would never consider doing unless I've heard other people doing it, I would never want to be the guinea pig here.

And honestly, if I am financially clever enough to understand your value proposition then I'm probably financially clever enough enough to buy some downside protection on general real estate assets.

The most interesting value proposition here is the ability to predict future home prices, but if you could really do that you would be working for one of the massive real estate funds, for the same reason that someone who is really good at picking stocks will work for a hedge fund (and eventually create their own), that person isn't going to decide to give investment advice to a gazillion pipsqueak investors or manage the accounts of a bunch of little investors, even if they can easily automate it.

In other words, the ability to predict asset prices is something that it makes sense to keep as private as possible, not something to share with the masses.

Customer testimonials is a great idea! Will add those to our site when we get a minute to do so.

As you said, they would probably go along way towards providing some additional comfort to any one who has some interest but is cautious about moving forward.

The questions you raise regarding our business model are good ones. As mentioned elsewhere in the comments, a fund is something that would be interesting but that we just don't have the capital for at the moment. Furthermore, our initial motivation for creating Lofty was to address the pain point of people wanting to buy a home but being cautious about the risk. As such a pivot to a fund, while similar in nature (and perhaps simpler in some ways), would be a pivot from addressing a real pain point we see in the market to just becoming another real estate fund and is in part why we are hesitant to do so, on top of the higher capital requirements.

Appreciate the feedback!

Since your model consistently beats the market and you can hedge at city level, Wouldn’t you be better off just raising money for an hedge fund that goes long and short with some leverage?

It’s a cool idea anyway, good luck

It's certainly something we have considered.

One issue is the capital raise. On top of that we really wanted to address the specific pain point of people wanting to buy a home but who cannot afford making a bad purchase. As such a pivot to a fund model would be a pivot from our initial motivation in starting Lofty. Nonetheless, it's an interesting idea.

Appreciate the feedback!

You mention that you hedge your exposure to market downturns through deep OOTM options -- would it be safe to interpret this as your company taking out OOTM puts on various REITs/ETFs? If so, I'm wondering about a couple things:

1. Do you hedge on REITs/ETFs with a local presence in the areas your properties are located in? If so, is there any liquidation risk of the REIT/ETF in the event of a major downturn that could force an early exit from your hedge position and leave you exposed to further decline? Also, how would you handle rebalancing/constructing new hedges when you add investment properties in a new area?

2. If you hedge on broader diversified REITs/ETFs, is it a plausible concern that your investment properties can be hit by a localized recession that leaves other parts of the broader real estate market unaffected, thus leaving your hedge unable to recoup the losses?

Yes, your interpretation is correct!

1. we hedge on both broader market REITs/ETFs as well as localized ones, depending on how many contracts we have in the local market.

2. Because we hedge on both, the probability of this is very low. Since a more granular hedge is an imperfect hedge due to the nature of these REITs/ETFs, it might not cover 100% of the localized recession. However, it should cover a large portion of it. So, our company will be on the hook for that remainder percentage.

We can cover it in 2 ways. Number 1, just use our own capital. Number 2, the profitable contracts in other areas not hit by recessions should be able to offset the ones hit by the localized recession.

I suppose such an investments would be useless after some time. Nowadays there are some powefull companies that manage an institutional-grade alternative investment fund that seeks to capture alpha from uncharted parameters in digital assets. By way of volatility harvesting and decorrelating algorithms, the firm identifies market dislocations that drive risk-adjusted investment opportunities. The first that comes to mind is https://cipher.tech/ and they can provide more opportunities for investments with high technologies ahead.

Against my better judgment, I'm gonna comment that I hate this.

This is certainly a good business/investment opportunity. If your algorithms are any good you'll make a lot of money, and you'll help your customers make money.

My problem with Lofty is that it is bad for society.

Fundamentally, this is gentrification-as-a-service. You're driving additional demand to neighborhoods at inflection points, and if it works well it's definitely going to accelerate displacement. It is true that Blackrock et al already do this and likely have similar in-house algorithms, but this will widen the market and make things worse. I'm not completely against gentrification, especially when there's development that increases market supply- and when done right that can actually decrease displacement. (an example you're probably familiar with is the USC Village. Despite the criticism it gets, it removed thousands of student renters from the South Central LA market which likely resulted in downward pressure on prices) But housing speculation like this drives up prices and only hurts poor and minority communities.

To Jerry and Max: did you consider the ethical implications when deciding to start this? I completely see the angle that you're democratizing access to an investment asset that currently mainly benefits wealthy institutional investors. I imagine, though, that a lot of people are going to see your team of young almost-all-white males and paint you as everything that's wrong with tech, and you should consider to what degree that assumption represents the truth.

You're absolutely right about this, and it is something we have and are considering everyday. I will be honest and say, at the moment, we do not have a perfect solution yet.

One of the things we looked into before starting the company was a paper that mentioned the Portland project, which showed that gentrification and displacement are not always synonymous. There, the neighborhood was completely gentrified, but the locals benefited greatly, because many of their home prices increased in value, and many owned local businesses that benefited from the influx with affluent people.

One of our goals is to see how we can use our data and business to make gentrification more like the Portland project. One idea has been to provide our data and analytics to city governments for free, so they can act faster in regards to setting up affordable housing.

In the meantime, our customers will be buying the homes, so someone has to act as the seller. If a local resident was the owner of the property, then hopefully, they benefit from the sale (we recommend our customers offer the "listing price" and not negotiate at all). If they are the renter, then current California laws should provide them a lot of protection.

It's not perfect of course, but we are looking for better alternatives.

> There, the neighborhood was completely gentrified, but the locals benefited greatly, because many of their home prices increased in value

But they lose mobility as their family needs change. New kids and need a larger home? You can sell yours, but the differential between a 2br and 4br is now outside your price range due to gentrified prices.

Also, it depends heavily on tax laws. Long time California home owners are protected from tax increases under Proposition 13, but many localities lack these protections, so ultimately higher taxes price you out.

You have a very valid point here. Our hope is that we can help them find new homes as well. Most of the homes selected by our algorithm tend to be very affordable, so a larger segment of the market can take advantage of appreciating home price. The goal is to make sure that not only existing wealthy people can benefit from rising home values.

In many of these poor areas being gentrified, people don't own their homes and they rent because they're poor and don't have the credit to buy a home. That's why gentrification is a problem - landlords increase rent because the area has higher demand, and effectively price people out of their homes.

These are precisely my thoughts, too. I try to keep myself from falling prey to the ultimate human indulgence of claiming to live in some kind of moral decline preceding some end times, but this is exactly the kind of thing that scares the shit out of me. Once people are paying 40% or 50% of their income to rents because they have no choice, what comes next? Combined with all of the enormous consumer debt...

This is a super interesting idea, and I have been wondering if there was a service like this. Is there something similar to this that recommends the house based on your stage of life? For instance, if you have a kid and your income is X amount, this is probably your best area or even if I wanted to retire with a set standard of living and maybe environment. This paired with home value appreciation that you provide would be awesome!

Love this suggestion! We have been toying with the best way to personalize the properties shown to each individual user. Right now it's just by city, max price and property type.

We also have added things like "near nightlife", "near trendy coffee spots", "near schools" in an attempt to capture what you have suggested here - albeit in a less efficient manner.

A "stage of life" questionnaire would be a great way to encapsulate all those above and more in an easy to interface with UI for the user. Thank you!!

Do you have a way to subscribe to updates? Would love to try out your service when you implement this!

Pretty cool concept! You're basically letting people buy into your real estate hedge fund. :)

Something I didn't see addressed in the FAQ: Do I get to include closing costs and agent fees in my cost basis before determining your 20% cut?

If not I can see a case where appreciation was minimal and I actually lose money one you get your cut because those fees eat up all the appreciation.

Thanks for the comment, but at the moment we do not cover closing costs or agent fees.

In the event that there is appreciation, but is minimal. We recommend that our client buys us out instead of selling the property. This way, they won't have to deal with the transactional costs, and with the low appreciation, the 20% cut will be very low, so it shouldn't be hard to come out of pocket for that.

As I've mentioned in some of the other replies, we'd love to keep innovating in this space and help reduce these fees, so our clients no longer have to deal with them.

Open Door is one of the companies doing a lot of cool stuff in this space, but we think there can be a lot of room for improvement. Statistically, a home is roughly 64% of the average American's total lifetime net worth, and we don't think people should have to pay so much fees on top of handling their life's most valuable physical asset.

It’s an odd business model. I think if you had any faith in your predictive ability you would just raise and run the fund yourself so as not to leave money on the table. This sounds like all the “crypto trading as a service” scams that have come up over the past few years. YC should avoid getting involved in trading businesses they don’t understand. Just my 2c.

This is totally understandable reaction to the business model. We do put our money where out mouth is but nonetheless it does beg the question of why we don't just do the investments ourselves.

One major issue is capital. But beyond that we also see a saw a market need for a product like this when trying to make home purchase decisions in personal life prior to creating Lofty. And that was the market and problem we wanted to address with this company - not just to be a big fund that buys real estate en masse and profits from it - but to help people who can't afford to make a bad home investment do so more comfortably.

Are you hedging with REIT options? Or home builders?

Are you able to hedge specific city risk?

Yes, we actually hedge with both depending on the area the property is located in. I hope you don't mind me not mentioning the specific products, since we don't want people in the market to bid up our hedging instruments and make them more expensive for us to buy.

We can look into the portfolio for a lot of the REITs as well as the exposure certain builders have. Based on that, we can hedge specific states and cities very well. It's not a perfect hedge, but it will definitely reflect the local real estate market.

Have you considered measuring RF activity in areas to approximate the number of people? I'd also imagine that a higher ratio of telecom bands as compared to wifi bands would indicate more bias visitors and therefore potentially more future growth.

This is a great idea! We do not currently do this, but we do take into consideration the availability of gigabit internet as well as overall connection speeds for different neighborhoods.

This has actually proven to be statistically significant for a large number of locations across the united states.

Huh interesting, that does make sense

> Before starting this company, my co-founder and I had tried to invest in homes.

Were you guys successful?

Haha not at all, since we never ended up investing. We were inexperienced and didn't really know what to look for. Homes that required extensive rehab seemed too daunting and a turnkey property in a nice neighborhood was too expensive.

(This will sound like we are very lazy...) We essentially wanted to buy an affordable home that would just grow in price over the next few years without us doing anything. At the time, there were no tools to help us find homes like this, which ultimately led us to starting this company.

This makes total sense. I've had 2 rental properties, and it sounds like you guys were looking for the same thing I was. Very interesting, I'm glad to see somebody tackling this! Why is the deal for 3 years? I would anticipate that your time horizon for a good return is much longer, given that the markets you are looking at are more up and coming.

Thanks for your interest! The ideal timeline is actually 5 years if we want to see the majority of the growth. However, since we won't be making any revenue from the agreement until at the end of the term, 5 years is too long for a startup to go without seeing revenue. So, it's mostly a way where we can see returns sooner, which is more attractive for investors.

On the plus side, our customers can choose to buy us out after 3 years, and see 2 more years of growth after, and they wouldn't have to share that profit with anyone.

Congrats on the launch.

> We were inexperienced and didn't really know what to look for. Homes that required extensive rehab seemed too daunting and a turnkey property in a nice neighborhood was too expensive.

1. what in your experience are the top 3 things to look for especially for a market like Bay Area ?

2. Follow up to 1. longer term do you think the model will do well for markets outside of Bay Area like Phoenix, Vegas etc.

2. How did you overcome the cold start problem for your models ?

(A while ago there was a podcast (IIRC from NPR) where Zillow ran a contest to reduce the error % of their price prediction model and the team that won probably ended up also using factors like direction of the sunlight etc.) 3. Given your competitors use these kind of data points, will your model rely heavily on satellite imagery etc. to infer these kind of data points in the future ?


1. A few of the top and more intuitive things we found in the bay area to be indicative of an upswing include an increase in food trucks and vietnamese restaurants. As well as increases in the number of social media postings about pets.

2. Yes, we believe it will. We have backtested on a ton of different markets and been tracking our models predictions in these markets over the past year and it seems to apply for most cities where these alternative data sources are present. Obviously (and perhaps interestingly) the things that seem to drive revitalization do have some constants between cities but they do also vary a decent amount by geographic area.

3. This was somewhat tricky. Obviously some of the sources we use like home prices and sales are more readily available and have existed for a long time. Others, not so much, especially for alternative data sources. We tried to choose sources that had been around longer (around a decade was a proxy) and had historical data that could be accessed via an api or scraping. This limited the list of sources we could use but we are quite happy with the list we ended up having that met this requirement.

And yes, we had looked at that competition Zillow ran and drew some inspiration from it. We do currently use satellite and street view data and are actively adding more uses for it, although we currently do not have the sunlight measurement per property integrated. I noticed that (i think?) as a new feature for homes when you look at them on zillow which was cool!

As a SWE and "retail" RE investor (I flipped 2 houses with ~15% return), a big problem with using online data to determine the value of the house is it just doesn't calculate the condition of the house. Even if you hire an inspector, they may end up missing something and you may end up needing to pay an extra $xx,000 in unexpected repair costs.

That's a great point! This is why we deduct any home improvement costs from the gross profit calculation. So, if you spent 10,000 fixing the pipes and the gross profit was originally 100,000, we would actually deduct that from the gross profit. So our 20% share would be on top of 90,000 and not 100,000.

Additionally, most of our customers still visit the properties we recommend before they buy, so these types of problems are usually spotted during inspection before the deal closes. This has filtered out any bad quality deals due to home conditions.

Hope this answered your question!

How much real estate investment experience is there on your team, then?

Most of the real estate experience comes from our advisors. One is a prominent consultant for cities on economic development using real estate. Another started Clarion Parters, which is a massive real estate investment fund. One of our early customers, Midwood, which also a large real estate investment, actually invested in us as well and joined the advisory board.

We don't pretend that we know more than others about real estate, because we are still mainly a tech company. Our expertise is in finding properties, using data, that can perform well, which has been the case both in back-testing as well as walk forward predictions.

This is why we don't handle the transaction process for our customers. Instead, we rely on partners that have more experience in these areas than we do.

To further ease people's mind, we offer the downside protection. So, if we mess up, we pay the price, not our customers.

Do you use all public data like census, BLS etc. or do you have paid data as well?

We do not use census data, because they are extremely outdated. It's part of the reason we can make accurate predictions before other companies can, since they do look at census data.

We use alternative data, which has recently become popular in the finance industry. For example, if you ask executives at a big company what their profit outlook is, they will always be optimistic, otherwise, their stock might decline and they may panic the market.

If you waited until the quarterly announcement, then you would be finding out at the same time as everyone else, and it's delayed information.

However, some people have found that you can more accurately predict a company's outlook on their quarterly performance by monitoring job boards and see how many open positions the company is hiring for. This allows people to gain insight and act before the rest of the market catches on.

We use the same approach but for real estate. For example, if you monitor the number of french bull dogs in a neighborhood, you can accurate predict median income values for that neighborhood before any official statistics. This is because those dogs are very expensive, so someone willing and able to spend a few thousand dollars on a pet tend to have a higher economic background.

We do use some paid sources such as satellite imagery and some data sources require you to pay for their api like our weather data vendor.

Thx for the response. We are trying to use data to help understand price movements in my own properties and I was trying to use ACS5 data, but when you get into obtaining access to tax record data it can get expensive quickly. Are you guys using any tax record data to obtain housing prices or ACS5 to get median income?

Yeah data is always a big headache haha, so I feel your pain.

We use MLS data to obtain housing prices historically. We don't use government data for median income, instead, we estimate it directly by tracking social media posts from the neighborhood that are public.

We then run image analysis on them to detect features like the types of dogs people have, types of cars, and other stuff. It's not 100% accurate for sure, but it's given us a pretty good understanding of the median income for neighborhoods, and the data refreshes in real time too :)

Very cool thanks for the insights! To run you model you must have some baseline data to be able to train against median income. How do you do that?

Are there any case studies you'd like to share, either here or on your site, or any other validation of your methodology? At the moment, it looks a bit like a "hot stock picks" newsletter.

We do have case studies, but they are bad in the case of presentation. We are a small team so when we decided to keep our analytics internal facing, we didn't spend anytime producing marketing materials or prospectuses.

So, most of the case studies are loss values printed onto our engineer's console or .png graphs showing our walk forward predictions outputted from our engineer's notebook.

If you'd like I can dig through our slack channel to find some stuff for you. I'll check back in later to see If I can find something more presentable as well.

If you're still interested, you can email me directly, and I'd be happy to send you some of the stuff I was able to dig up.

Hey, this seems pretty cool. What are your thoughts on landscaping/ outdoor water use?

If that seems interesting to you and your team, you should hit me up.

What is role of Real estate agent in your business model? Why would a buyer be willing to shell another 3% for a Buyers Agent?

This might not be the case everywhere in the country, but typically, the seller is responsible for the agent fees. This means that if we recommend an agent for our customer, who is the buyer, that agent is actually paid for by the seller.

We have the relationship, because we do have customers who are very inexperienced and this would be their first purchase. So, a lot of them still want to have to ability to talk to an agent and ask questions about the home buying process.

Is it possible to recommend a real estate agent to you?

Sure! We are always happy to add to our list of preferred agents that we recommend to customers who are unsure of which agent to go with.
