Labeling them freaks is a bit harsh but no.

And then I would not make the rental agreement more harsh. 

There is just to much drama going on here.

Tons of noise and drama, her throwing his furniture into the building hallway while screaming at the top of her lungs, cops being called, and even his blood on her - she'd attacked him!  

The main thing is to ask open ended questions and follow up questions and LISTEN. 90% of those with drama will tell their "story."

And, the difficult tenants are more quickly gotten rid of, when you do month to month agreements.But, I'd say, that no matter how great you are at screening, 2% of high-maintenance PITA tenants will still squeak through your great screening.And the worst things they ever did was let some insane BF/GF move in and create crazy drama, or sneak in a pet rabbit.  

This is my second multi-family and is the first time I've had this kind of drama.  

Steve DellaPelle I don't mean this to sound harsh,But not collecting a deposit is an awful idea.

Not to sound harsh but if he truly is "going to die soon" perhaps it is better that you do nothing it terms of "getting rid of them" now. 

Sounds harsh but turn the tables- will your mortgage company give you a pass if the mortgage doesn’t get paid?
