A cancel lease letter is a formal document used to terminate a rental agreement before the expiration of its stated term. It should be written in a professional and respectful tone, outlining the reasons why the tenant wishes to end the agreement. This letter must include all pertinent information related to the rental agreement, such as rental period, property address, contact details of both parties, termination date, and any relevant deposit returns. In some cases, the landlord may be willing to negotiate the terms or offer an alternative arrangement – it is important to clearly explain in your letter what you expect from the conversation. Ultimately, this letter serves as an official record indicating that the tenant has opted to no longer use the premises for their desired purpose.
