What would you do?
I was listening to the radio this morning and someone called in with a problem. They live in the top floor of a duplex with their three kids. They own their unit, but not the unit below them which is currently being rented out. They're neighbors below are constantly calling the police to file noise complaints because they can hear the kids running around. According to the parents the kids aren't being overly loud or obnoxious, they're just playing normally. The building is older so sound travels easily between floors.
They're tired of constantly dealing with the police just because their kids are playing. They've tried contacting the landlord of the unit below them, but he's not any help. They don't want to move but they don't want their neighbors to constant bother them about noise when there isn't anything they can do.
What would you do? Would you move? File harassment charges? Have you ever dealt with something like this?
My point is, if you know you can't handle living under someone then you leave when your lease is up. Until then, you suck it up.
