I have $400k in accessible cash looking to deploy towards real estate.

One thing that wasn't mentioned is that the road leading to many of the homes often floods making a good portion of the rental homes inaccessible during storms & also resulting in early evacuation due to storm threats. 

Then  have a third-party entity buy those mortgages and put proceeds into an inaccessible account in their international trust.

As every year there is more people in the U.S. then the year before, if the $ supply stayed static, it would mean the existing $ supply get's split by more hands, and that would cause a DEFLATIONAYRY event in the $supply, which would cause restriction in access too $, slowing economic activity and, cause INFLATION to the cost of $, resulting in INFLATION to all items due to this restriction, from simple demand-supply relationship. 

They have taken in access of 8 figures from all of us since 2006!  

Common mistake by those new to real estate but this 45k in equity in accessible.

I know that equity value is almost always inaccessible so it's not liquid unless we refinance or use a HELOC to realize it.  

I have a couple of Air BnB units that are inaccessible at the moment due to the flooding.

Add in access to a well-designed airport that has nonstop flights to most of the country.

If something goes wrong, you've invested "extra/saved" money not "desperately need to eat money"I wouldn't go to college just to go to college - while I don't think RE investing is inaccessible, I just think its a difficult path to jump into without some financial stronghold behind you.
