In my city (Christchurch, New Zealand), renting is more expensive than mortgage repayments for an equivalent house. I don't see how renting could be a good idea in this case.
That said, I recognize that different cities have different conditions, and what makes sense in one city might not make sense in another.
Rent is an all-inclusive expense usually, while a mortgage is not. Rent covers maintenance, taxes, cost of future renovations, and you usually don't have high transactions in getting or leaving an apartment. So you can't directly compare mortgages and rent amounts.
Hah! I live in Christchurch too, and yes, rents have gone up, and yes, like everyone I've been thinking about buying.
However! I'm also from Ireland where a _lot_ of my friends bought houses in the celtic tiger era and are now, on average, about 100K euro down on their "investments"
My gut feeling is that Christchurch too is a bubble. Sure it's a bubble fuelled by a nasty earthquake reducing the supply... BUT supply will come back up again (and it'll be new housing with things like insulation!)
Tricky things really. Currently my rent is cheaper than a mortgage for an equivalent - but only just. That said, I don' t have to pay rates, fees, hiked insurance etc.
The other option of course is to leave for a while - easy enough to do as a decent developer.
I've actually never got one myself, because I'm still at university. However, banks seem to be willing to lend up to 80% of the value of a house, for someone with an average income.
I suspect the biggest problem is simply that houses are very expensive compared to most of the USA. I'm flatting in a really crummy house (as in, cracks in the wall) on a quarter-acre section, yet the property is valued at $500,000.
That said, I recognize that different cities have different conditions, and what makes sense in one city might not make sense in another.
