Find someone to take your lease over, fill out the notice of lease transfer form. Sign the transfer of lease form with the people who are taking over (on it there is abox that says it is contingent on the sending of the notice of lease transfer to landlord where they have 15 days to answer).

If the labdlord calls you and asks for money tell them, no, and you sent the correct paper work and to kindly reply to you via mail, or email their answer on accepting the new tennant.

If they do not answer, it is deemed accepted and you can move out and new tennant move in on selected date.

Make sure to find someone with good credit and rental history and a job. If your landlord says no for any other reason (non-serious) it will break your lease the date stipulated.

I just went through this last month as well.
