Ohio Rev. Code § 303.44
In the event of the levy of special assessments against lots or lands within a county renewal area which lots or lands are or become county-owned, the board of county commissioners may authorize the amount of the assessments thereon, or the amounts of the respective unpaid installments of such assessments, to be certified by the clerk of the board of county commissioners to the county auditor, entered upon the tax list of all taxable real and personal property in the county, and collected as other taxes, provided that such certification for payment by the county at large shall cease upon sale of such lots or lands by the county. The unpaid portion of such assessments on lots and lands so sold shall continue as liens against the lots and lands in the hands of such purchasers, as other assessments, and shall be collected as other taxes.
