Also, the disturbance is an issue, but should have been addressed very early on.

Example: Tenant experiences a loss due to some house issue.

You did a great job on most of the details but it looks like the floor plan you started with is now the issue and is not really correctable.Looking at the Zillow map of the area, I see very few houses over $400K and most around you are about $100K+ under yours. 

Main issue these have is tree roots grow into them.

Hi David,(1) I don't have much to invest ($280-$350k) and would want to diversify across different properties anyway (some DSTs are diversified, and I can probably pick up three different DSTs with my proceeds);(2) no direct participation in managing properties (tired of it);(3) illiquidity is not an issue (looking for a 7-10 or longer horizon, will need some cash 8-20 years down the road to fund the kids' college);(4) prefer paper investments in general, would be able to hedge declines in the real estate market with financial instruments (have a Ph.D. in finance and a CFA designation, but a newbie to RE exchanges).

House hacking and FHA loans is a common strategy.
