Landlord termination form month-to-month rental

[Tim B.]

Any recommendations for a form to use for a TX landlord to terminate a month-to-month agreement? The initial term of the lease expired and the lease now automatically renews on a month-to-month basis. The effective date will be the end of the month following the notice.

Any recommendations, links to forms or templates, sample letters would be appreciated.

Also if there are any best practices I'd be interested in hearing them.
