Emergency Maintenance: Regular maintenance is on the owner, emergency repairs might be charged to tenants if they caused the problem.By proactively managing these expenses and clearly communicating responsibilities to tenants, property owners can maintain their properties effectively while minimizing unexpected costs.

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.

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. 

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.

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

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

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