Termination of your rental or rental agreement is possible at the end of your fixed or anticipated term if there is an interruption clause in your contract. If you leave on the last day of your fixed deadline, you will not have to cancel if your fixed term was 6 to 12 months. Use our termination letter to terminate a lease. As a tenant, you may have a very good reason to terminate your contract prematurely. If you have asked your landlord to repair the heating without luck in winter, you may find it useful to send a final letter. Terminating a lease to the lessor may explain why you think the landlord has violated the implied guarantee of habitability and why you need to terminate the contract and find a warm home for you and your family. . . .
