Ohio Revised Code Title LIII. Real Property § 5313.07

If the vendee of a land installment contract has paid in accordance with the terms of the contract for a period of five years or more from the date of the first payment or has paid toward the purchase price a total sum equal to or in excess of twenty per cent thereof, the vendor may recover possession of his property only by use of a proceeding for foreclosure and judicial sale of the foreclosed property as provided in section 2323.07 of the Revised Code. Such action may be commenced after expiration of the period of time prescribed by sections 5313.05 and 5313.06 of the Revised Code. In such an action, as between the vendor and vendee, the vendor shall be entitled to proceeds of the sale up to and including the unpaid balance due on the land installment contract.

Chapter 5313. of the Revised Code does not prevent the vendor and vendee from cancelling their interest in a land installment contract under section 5301.331 of the Revised Code.
