Read your lease carefully between you and the landlord in that its terms control the obligations and duties that you and the landlord owe each other concerning the unit you were renting.If your lease was a fixed term, you are ending it at its term's end, and nothing is mentioned within about a pro-rated termonation fee or termination penalty fee, then you should not be charged this by the landlord at the lease's end. Even if there was language in the lease as to such, your state's statutes on the subject may deem the language illegal and unenforceable.You should write your landlord a letter on the subject and the reasons why you do not consider the provision valid, keeping a copy for future reference.Good luck.
