Month to month rental agreements, also called ﾓperiodic tenancyﾔ agreements, are rental agreements where a tenant rents a property on a month to month basis, without signing a lease for a fixed term. The agreement may automatically renew each month until either the tenant or the landlord decides to terminate the agreement. Month to month rental agreements may be terminated at any time with proper notice. Usually one month's notice is required, though specific laws sometimes vary. Month to month rental agreements may be oral agreements or written agreements. Written agreements are usually preferred to guard against potential rental disputes. Often the tenancy of a renter under a fixed term lease may convert to a month to month tenancy after the lease expires. This means that a tenant with a year long lease can continue to occupy the property under a Month to month rental agreement once the lease term expires.
