One of the things he was working on was smaller multifamilies under 10 units -- trying to find the factors that would keep those properties rental potential and therefore resale value up versus those that had crashed. 

Few have sold a lot of their property lately because they think Currency and Stock Market are crashing very soon and everything else will follow.

Major market changes will impact them - ie the last real estate crash in PHX where homes were renting for less than apartments. 

I never really had any stocks/bonds or much cash but after living through the 2008 crash in Vegas and San Diego I committed to having a lot more liquidity at all times going forward.

Could spike today and totally crash tomorrow.

It has caused crashes resulting in bad press coverage.

Yes the world's economy may crash,but I care far more about my personal economy, and I have busted in a boom market.

Well, okay, maybe not in a post-crash environment.

But still, in a crash those will still be tiny returns but look better than losses.  

I would not do this again at that price point way to risky that was pre crash were everything was possible and we did not know about a huge downside.
