What if I need to break my lease in NJ due to a job relocation?

There is usually a price to pay for breaking a lease, so talk to your landlord to see what he requires. Usually the penalties are in your lease agreement. What does it state as your responsibility for breaking it are?

You don't. You have two choices; negotiate a buy out with the landlord or sublet. Of course you could have a sweetheart of a landlord who will let you out of the lease.
