I have a rental property in New York that's currently occupied by a couple who has decided to split up. Their lease ends in May but the husband has already moved out all of his things and has found a new place. Today they have informed me that worse case scenario they will pay rent for another month (FEB) but the wife can not maintain the space on her own and is currently looking for new diggs as well. What is the penalty for early termination of a lease?
