(1). First of all, you must talk to the landlord in order to solve this problem - your problem;
(2). How to talk? there are many methods and techniques. In a word, you must find out GOOD reasons before negotiating with the landlord. Secondarily, application of language is a key point.
(3). There were some true cases of terminating a lease, as I know, in which about 50 to 100 dollars was paid for termination, depending on how "tough" you are.
Any more questions? Please feel free to ask. Thanks.
