It is very important that you give me a proper and timely move-out notice before you leave. For a number of legal reasons. I cannot rent your apartment or even advertise it for rent without a move-out notice from you. Your move-out notice must be in writing. That is in your lease. You have not given me a move-out notice by calling me on the phone and telling me that you are leaving.  A voice mail message is also not a move-out notice. An e-mail is not a move-out notice either. A written move-out notice means exactly that – it must be in writing. Your move-out notice must be dated, it must state the address being rented, it must include a specific date by which you will move out, and your notice must be signed. Your notice must also be definite. I sometimes get move-out notices like this: “I will be moving out by July 1 unless I can’t find another place to rent by then.” This is not a valid move-out notice because it is not clear that the tenant is actually leaving. I cannot rent your apartment to a new tenant if I do not know for certain that you are moving out. You can deliver your move-out notice to me personally or you can mail it.
