Also one can protest their property taxes fairly easily.

Fair enough?

We have our lease terms but are flexible and treat people fairly.

Ensure the sale reflects fair market value to avoid gift tax.

In my experience, the turnaround time is fairly short and can be done in January/February and still leave enough time for your accountant to file taxes. 

It was in fairly good condition, and I KNEW I could easily lease it out, or lease sections to various business, or sell it for double or triple what I paid. 3 years later, having not even received an offer to lease AT ANY PRICE, I sold it for $25,000 LESS than I had paid.

If they are VERY professional, they will have their processes in writing as verification that policies are enforced equally and fairly by their entire staff.6.

Fair Housing specifically forbids discriminating against "familial status" which includes foster children.

In my opinion, you need a standard (eg. no felonies) that is written and followed consistently to avoid fair housing issues. 

Treat everyone fairly and follow the rules and you’ll be okay.
