If the one year lease ends and the tenant wants to stay, do we ask the tenant to sign another lease?

At the end of the initial lease agreement, if the tenants wish to stay on they can choose to stay on a month to month basis under the same terms and conditions of the expired lease. The tenants are not obligated to renew for another year. On a month to month tenancy the tenants must still give 60 days written notice when they decide to move out. However, when the landlord is giving notice to the tenants the notice period will depend on the reason to terminate.
