Can my rent be raised if I have a lease agreement?
I have a lease agreement with my current landlord. It is for 1 year. She is selling the property. When the new landlord assumes ownership can they raise my rent? I also have a dog. Can they make me get rid of the dog. It is written in the lease that I may have 1 dog.

Breaking a Lease Agreement
My ex has threatened to kill me and my fiance in our sleep. His girlfriend lives down here now and my ex was told he was not supposed to be down here. I have sent pictures of him being down here to the landlord. He siad he would get it solved but he still hasn’t. If I dont feel safe by law can I break my lease?

Apartment Issue
I remember when I first moved in they told me it would be 200 dollars if we did not prime all the walls back to white, so we painted all of the walls in our apartment, now they are telling us that it is 50 dollars a wall. To equal 1350.00 But no where in the lease agreement does it say that its that much a wall. All that it states is that the walls must be returned to the white they were originally at, it has no dollar amount what so ever. When I confronted them, they told me that it was because that is what the painting company charges them, but I called another IPA apartment group and they said that they never charge over 100 dollars. So my apartment place is being shady I know it. They said that they do not need to list an amount because it is considered a ”damage” and they access it at the end when you move out. What do I do, I have 2 other people that heard the girl tell me it was 200 dollars if it wasnt primed back. Please help me! Thanks
