DST's are complicated.  

Don’t make it complicated.

Investors do this to protect themselves in the event the note goes into default, they can avoid a judicial foreclose (expensive and time consuming) and just take the property back, and resell it.  

These deals are risky and complicated.

There are rules in Ohio where if the borrower has more than 20% equity or has held the land contract for more than five years then the lender must go through a judicial foreclosure as if it was a mortgage. 

The one and only time I've heard Dave Ramsey address the idea of "good debt" and "bad debt" with enough time given to make a complicated point, he talked about how difficult it is, specifically in real estate, to precisely calculate the risk of these investments. 

The feedback I usually get is that buyers wanted to assume the loan but the process was lengthy and complicated, and buyers eventually moved on leaving the seller with no equity and option to sell other than writing a fat check at the closing table since they had to continue to lower their price.

If the plans are super detailed or complicated forget about it. 

You are making it more complicated than it needs to be.

@David G. your making this WAY more complicated than it need be.
