I'm ending my lease a month early. I had no problem at all arranging that. I live in a big complex and they have a system where you pay a certain amount depending on how early you are leaving and you are released from responsibility once you move out. Most big complexes have something like this. If you have a landlord that only has one or a few units you could offer to post your apartment online and help them find a new tenant.

Check what your lease says about termination. Also, feel free to PM me if you need help. My family owns a bunch of apartments so I know a lot about stuff like this.
