Whatever you decide @Larry H. just be certain that you are on the right side of the law by getting legal counsel from an attorney in or near the jurisdiction your properties are in. There are jurisdictions (parish to parish here) that have very different attitudes toward landlord vs tenant situations.
There are reasons why LA is where it is on this list:

Your tenants are immersed in advertising (billboard, TV, radio, etc.) to pursue legal action in the event of any accident, injury or incident and with "hungry" attorneys everywhere you turn, you will have to defend yourself sooner or later.
It sounds like your father-in-law is great for the role you want him to play. It's just that the laws cover some things that seem like an innocent practice that are covered by specific laws. For example, "NO PET" policies have different rules under ADA and the Fair Housing laws that mean you have to allow the animal because it's not considered a pet, but a necessity. Especially when you are participating in housing programs that can make you subject to close scrutiny for specific Fair Housing and ADA requirements. Again, its a matter of how the local administrators enforce the rules. It would be nice if they were consistent with how it works, but its implemented differently from place to place.
The bottom line is get legal advice from an attorney you would consider hiring if you were being sued for something that happened at your property. You might need them again in the future and it never hurts to have the relationship established before you need them.
