tenant on month to month lease

[Marc Shin]

Hello. First time REI owner. I have a tenant on a month to month lease. How do I go about ending their lease? Do I send them a letter, and then follow up with a phone call? Does anyone have an example "lease ending" letter?

What do I say to them on the phone and how do I say it to them so that they agree to end the lease and leave in a peaceful manner?
