An End of Lease Agreement Letter is a document that outlines the terms and conditions of the end of a tenancy agreement between a landlord and tenant. It typically details the date of completion, any outstanding payments or fees owed, any damages that need to be repaired before the lease ends, and how the security deposit will be handled upon termination of the lease. By signing and submitting this letter, both parties agree to the terms and conditions described within it, thus providing peace of mind for both parties involved.
