I hope you called the cops.

As a real estate agent I can tell you that you have the right to "quiet enjoyment" of your property. She's not allowed to enter your apt unless there's an emergency (broken pipes, fire, etc...). You can definitely get a law suit out of that.

Call cops, file complaint, start looking for a new place to live asap.

There's a lawsuit.

Most definitely illegal! Your crazy if you don't call the police. In most cases she can't even enter your apartment without 24 hours notice, let alone take anything that doesn't belong to her! Don't with hold your rent though, it doesn't work like that, you would just have to pay it back to her in the end anyways cuz she's still providing you a place to live. You can't break your lease just cuz she's a douchebag.

Man, you can sue the shit out if her. Even if you owed her lots of rent or had abandoned the unit she has ti go through a long process before she can touch any of it.

Erm, speaking as a landlord myself....nope that is bull.

call the police. That's illegal. It may be in her building, but it's your property

Take her to court!! What the hell?

Police. That's what they are they for. Duh.
