Take some time to meet with your roommates or partner to come up with a plan on when you hope to move. One of you might have to exit the residence first and live at the new one until the old lease expires.
Do make time to sit and talk with your community manager or leasing consultant so that you are exiting properly. You will need to give a move-out date, arrange for movers to come, apartment clean up, and a walk through prior to departing.
Start noting some of the issues now. Get on the phone with maintenance and get some repairs done prior to moving out. This is also a good time to start giving items away, selling what you can, and telling others about your departure plans that could help you during your relocation process.
