Both new and seasoned investors can gain wisdom from the harsh experiences of others.

May sound harsh, but I believe that this is the attitude and actions that it will take to be successful.

The answer is purely intellectual.....Money.Have your MIL offer cash for keys by telling him she will forgive the rent and return the deposit in full if he will vacate the property as soon as possible and without any trouble.If necessary,offer more money on top of the deposit return to help him pay for moving and into another place.This clown is a ticking time bomb with nothing to lose and will destroy the property if challenged harshly so tell her to smile big and be sympathetic to his divorce troubles and help him get the hell out asap.

This process has been a lot of drama and I've heard bad things about the new management co.

Best thing I ever did for stress free drama.

Sorry if this sounds harsh but the truth is, at least in my opinion, no money down is BS.

The drama that is potential is not worth the aggravation. 

Google Portsmouth city council, Portsmouth chief of police, PRHA Hud investigation just to get a peek at some of the recent drama. 3) If you plan to SEC 8, Portsmouth is the worst of our cities to deal with.  

He also said that everyone gets along and that there is fairly low drama.

On the people side of management understand that a 12 unit apartment will be 12 times more involved than a single family. 12 times the vacancy and occupancy issues, 12 times the personal drama issues, 12 times the leasing issues, 12 times risks of late payments and legal aspects.
