I have a roommate that I have been living with for 3 months. She is constantly late on here rent and/or never pays her full amount Owed. My roommate now says she is going to pay less then what she originally agreed to. On top of that she has animals that piss and poop all over the place. It's disgusting! How do I get her out if she is on a lease with me? I can't deal with this anymore!
