An early lease termination addendum allows a landlord or tenant to cancel a current lease by a specific date or by the landlord or tenant providing written notice. Terminating a lease early requires the consent of both the landlord and tenant. In most cases, the tenant will request to terminate the agreement due to loss of employment or income. In such a case, it is in the best interest of the landlord to release the tenant from the lease and keep their security deposit in the process. Otherwise, facing eviction is a long and expensive process due to attorney’s fees and the loss of rent.
