A Rental Agreement form can be helpful if you are trying to rent your property in a hurry. Also known as a month-to-month lease or a "tenancy at will", this form can be used instead of a Lease Agreement when you want to make a short term rental arrangement. Unlike most lease contracts, rental agreements can be terminated by the landlord or tenant by providing a Notice to Vacate in accordance with state law. This form is free, simple to use and available in state specific versions.
