We have just purchased a flat for a buy to let. It is top floor with another flat also on the top floor. Every time I go over to check on the flat the next door neighbour has a bin bag out side his door ( opposite my front door) and it stinks. The whole communal areas smell of his rubbish and is very unpleasant. I have now found a tenant. Am I being unreasonable to still be worrying about this as it is not very nice for my tenants or do you think it is now their problem. He also smokes which stinks but not a lot you can do about that!
