A rental agreement differs from a lease agreement in that it is not a long-term contract and usually occurs on a month-to-month basis. This month-to-month lease agreement expires and then renews each month upon agreement of the parties involved.
Whatâs the Difference Between a Rental Agreement and a Lease for a Rental Property? When you rent out a property, you will need to decide if you wish to offer your tenants a lease or a rental agreement. Although these terms are often used interchangeably, they are not the same. A lease has a set term, such as six months or a year, during which the tenant agrees to rent the property. During that time (also known as the duration of the lease), the tenant and the landlord must adhere to the agreement. For example, tenants agree to make monthly rent payments and follow any code of conduct or other stipulations in the lease.
