A month-to-month lease is a type of short-term lease that allows either the tenant or the landlord to give notice before ending a lease contract.
Month-to-month leases don't have a set end date and can go on for a long or short period of time. They can be terminated by either the landlord or the tenant for any reason. Whichever party terminates the lease must do so in accordance with state laws and the original lease contract terms. Some states may require 90 days notice and others may require only one week.
If you don't want to commit to a fixed-term lease, a month-to-month lease gives you more flexibility in both moving out and rental terms. If you need to move out, simply give your required notice. Or if you end up staying longer than you had anticipated, you can.
But just as you can give notice and move out quickly, a landlord can choose not to renew your lease and leave you with no choice but to find a new rental. And month-to-month leases may be subject to change, meaning there could be new terms or an increase in pricing.
