(2) If a redemption payment plan is entered into pursuant to division (C)(1) of this section, the county treasurer immediately shall notify each certificate holder by ordinary first class or certified mail or by binary means of the terms of the plan. Installment payments made pursuant to the plan shall be deposited in the tax certificate redemption fund. Any overpayment of the installments shall be refunded to the person responsible for causing the overpayment if the person applies for a refund under this section. If the person responsible for causing the overpayment fails to apply for a refund under this section within five years from the date the plan is satisfied, an amount equal to the overpayment shall be deposited into the general fund of the county. If the county has established a county land reutilization corporation, the county treasurer may apply such overpayment to the payment of the expenses of the corporation.
Upon satisfaction of the plan, the county treasurer shall indicate in the tax certificate register that the plan has been satisfied, and shall notify each certificate holder by ordinary first class or certified mail or by binary means that the plan has been satisfied and that payment on the certificate or certificates is forthcoming. The treasurer shall pay each certificate holder promptly.
If a redemption payment plan becomes void, the county treasurer shall notify each certificate holder by ordinary first class or certified mail or by binary means. If a certificate holder files a request for foreclosure under section 5721.37 of the Revised Code, upon the filing of the request for foreclosure, any money paid under the plan shall be refunded to the person that paid the money under the plan.
