What is required in a 30 day notice letter from a tenant to landlord in Massachusetts

Assuming you are a ternenat at will ,ie month to month with no written long term lease agreement, there is no specific requirement but it should state clearly that you are terminating the tenancy by a certain date. You will have to have all your possessions out by the end of the day on that date. You also want to make sure you can show the landlord received the notice, just in case there is any dispute later on. The easist way is to send it certified mail-return receit requested. You should also provide a forwarding address and phone number so they can send you the security deposit if you paid one.
