A better movie for this topic is "Pacific Heights", where Michael Keaton's character makes a rent pre-payment (and engages in some disturbing behavior as well).

Hi @Catherine Decker - I vote for the "no trespassing" as a first step.Next, people will change their behavior once the see signs of your property being actively managed.

I have wondered it there was something about my behavior.

When he doesn't get it from the next guy he damages the house or leaves a big water bill or some such behavior and a bad tenant is born.

It's a miracle they didn't burn the place down, as it was apparent that they just dropped cigarettes regularly, that just burned themselves out on the carpet.So, did the co-signer change the risk/behavior of the tenant who wouldn't qualify without one?  

Then, you would be even more restricted as far as acceptable grounds to evict her, from my understanding of Section 8 rules.Your best bet to getting her out before November, would be to start documenting her behavior and giving her written warnings - but it would have to be behavior that is something you can evict for.Did the police come?  

He has history of fraudulent behavior. 

I suppose I worded that wrong I would never blatantly lie, I should have worded it as ‘am I legally obligated to give full disclosure of this tenant’s habits and behaviors’

Furthermore, service dogs have behavior that is exemplary. 

She knew her debt to income would be an issue by her behavior.
