File a No Trespassing Warning with the municipality.

People were warned but chose to ignore.People want to believe in the dream.

Warning, not all but most window units with both need a 220V outlet.  

But, remember you were warned.

@Lucas CarlI give one polite warning.

If I was your wife, I'd be hearing you accentuate the positive all day long and warning bells would be exploding in my head.Just for starters, let's get clear about third-party Section 8 multifamily property management -- the guys who do it are in it to bleed you as much as possible.

This way it presents a fair warning!

They'll freak out for a minute, even if the seller actually did warn them of an increase, because they always still freak out and get irritated, but then they shop online to see what they could get and unless you price them out, they usually stay. 

If the breed of the animal means you can lose your insurance, then you can deny the animal - or rather their request for a reasonable accommodation - based on the request creating a financial hardship for you.But, since you've already allowed it, now your easiest way to get rid of them is to start giving them warnings based on the animal's behavior. 

But, at minimum, you will at least be able to get it on her credit report, which will be at least a consequence, and it will be a warning to the next landlord not to take her.
