Here is some background and my idea.

The people that run these companies usually come from an "investment banking", real estate, or construction background.

Then you have someone who understands the investors goals well and the technical experts really working together effectively. 

Guests staying at a discount, technically called "below market rate" is ALSO personal use!

Meanwhile he has gone so far as to update his profile page background to promote  a 3 day wealth summit.

Technically speaking a buyer and a seller being in a dispute on what happens with their earnest money isn't something that would prevent the seller from entering into another contract and selling their property to a different buyer. 

This doesn't mean you cant reject an applicant for other reasons you typically would such as income, poor credit, or criminal background. 

Lastly, while Section 8 tenants can technically apply to any home, it has to be approved for the program, and not every property is eligible.

How does it feel - Like that scene in Shawahank Redemption with Tim Robbins standing in the rain liberated, with glorious music playing in the background???

But it is technically illegal to do so.
