----------------------------------The collapse of the real estate market intown Atlanta was hugely effected by the systematic mortgage fraud that was being done by groups of scammers. 

-roughly 1,000 acre parcel for sale-Land held under an LP/LTD (multiple parcels for sale together)-owners took out large development loan pre-recession and defaulted once market collapsed-small banks bought up loans, those banks failed and got bought up by bigger banks.

I disagree with your theory in a market with higher prices and desirability other investors are willing to accept a lower return because they are fairly sure the market won't collapse out from under them. 

Think how many  folks there were that got all those mortgages that ended up collapsing the financial market.

This is an interesting question, because in 2009-2011 I took a lot of risks, by buying in the face a collapsing economy.

I expect it to collapse similar to stewarts creek, which has become quite the cesspool.

I just saw Equity Build was shut down, ruled a Ponzi scheme, and ripped off investors to the tune of $135MM. Anyone get caught up in it? If so, what is your story??? Ripoff Report verified them! Ripoff Report Verified...

Are there other potential non-rehab/non-tenant pitfalls that result in a deal costing more money than anticipated or even the collapse of the deal itself? 

I know that Russia and China are trying to dump the dollar, which won't work, and that Turkey, Venezuela and Argentina are on the verge of collapse.

The first is Catastrophic Ground Cover Collapse (CGCC).
