Check the state rules that change the bid
Read the Ohio due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth.Set a walk-away number
Work out what the parcel is actually worth with the rural land value estimator, then turn it into a ceiling with the tax deed max-bid calculator.
Over-the-counter (leftover) purchases
unsold liens and deeds
Ohio has no over-the-counter tax certificate channel. The equivalent inventory is the county auditor's forfeited land list, made up of parcels that drew no qualifying bid at two foreclosure sales. The auditor offers that list at public auction at least annually, and a tract that still receives no bid meeting the statutory minimum may then be sold for the best price obtainable.

Ohio rules
- Redemption
- Ohio has no post-sale redemption window. On the certificate track the owner or any other person entitled to redeem may pay the county treasurer at any time before the certificate holder pays to start foreclosure, and after that up until the entry of confirmation of sale, the expiration of the 28-day alternative redemption period, or the decree that conveys title to the certificate holder. On the direct foreclosure track, delinquent land may be redeemed before proceedings begin, and afterwards up to the entry of confirmation of sale or the end of the alternative redemption period. The alternative redemption period is 28 days after an adjudication of foreclosure is journalized, and when it expires the right and equity of redemption terminate without any further order. Once title vests, a decree conveying the parcel to a certificate holder is a permanent bar to redemption.
- Deed deposit
- For residential property the deposit is fixed by statute: $2,000 if the appraised value is $10,000 or less, $5,000 if it is above $10,000 and up to $200,000, and $10,000 if it is above $200,000. A judgment creditor buying at its own sale posts no deposit. For commercial property the deposit follows whatever requirements the sale sets. Deposit timing is set by the court or the officer conducting the sale and printed in the sale advertisement, and an online sale may take the deposit by card or other financial transaction device.
- Surplus proceeds
- Sale proceeds pay costs first, then the certificate holder or the taxing districts, and any residue goes to the clerk of the court within 45 days after confirmation. The clerk notifies the former owner. Residue left unclaimed 90 days after that final notice is paid into the county treasury and held for the owner, who may demand it within three years. After three years it is forfeited to the county's delinquent tax and assessment collection fund, or to the county land reutilization corporation fund where one exists.
A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
