In 2008 all real estate valuations were crushed due to the nature of the crisis, but real estate has historically been a pretty stable asset class in recessionary environments.
So in terms of recession proof REITs - commercial or residential?
They are more diversified than their names may imply. You may end up with odd overlaps if you dont look at their underlying sector breakdowns.
it was moreso that just cuz you got lucky and got in and out of a scam at the right times, that in and of itself doesnt invalidate the strategy itself.
And like the other person commenting said, the 2008 crash was a real estate crash.
