Notice and possession
Ohio Revised Code §5321.17 calls for written notice at least 30 days before the next rent due date to end a month-to-month tenancy, or 7 days for a week-to-week tenancy. Read Ohio Revised Code §5321.17.
A notice period is not a move-out date. Tell us the timing you want, and we can discuss a sale with the tenants still in place.
