I live in a duplex, rent one side and live in the other. Recently a family moved in next door and have been causing trouble for the entire neighborhood. They come up on our porch, play in the bed of my truck and use our lawn as a personal playground. My tenants have informed me that they plan to move out as soon as there lease is up because of them. I have talked to the parent, the police and the management company who owns the house next door and no one seems to care. What can I do to get them out. I am losing money both from rent and property value.
