When it runs
Annual, held on a Friday in December. The Treasurer's notice states: "Pursuant to Ohio Revised Code 5721.33, on Friday, December 12, 2025, John McManus, Montgomery County Treasurer, will offer parcels in a Negotiated Tax Certificate Sale." That December 12, 2025 sale was the most recent date posted when this page was reviewed; the following year's date had not yet been published.
Registration and deposit

No public bidder registration is published. Montgomery County sells under the negotiated procedure of Ohio Rev. Code 5721.33, and the Treasurer's notice states: "The tax lien certificates are not available for purchase individually." Certificates are conveyed in a negotiated block rather than parcel by parcel at open auction, so retail investors cannot bid on single liens. Investors seeking access should contact the Treasurer's Delinquency Department at 937-225-4010, option 2.

Sale format and venue
This is a lien sale, not a property sale. The Treasurer's notice states "A tax lien certificate sale is not the sale of property" and that "All parcels with delinquent taxes are eligible for this sale." Once a certificate sells, the owner owes the delinquent taxes plus a $400 administrative fee, any applicable premium, and up to 18% interest. One year after the sale date the certificate holder may begin foreclosure. Unpaid current taxes let the holder buy a second or subsequent certificate on the same parcel, adding another administrative fee plus 18% interest. Owners can stop a sale by paying in full before 4:00 p.m. on the sale date or by starting a payment plan with 20% down. The notice points to www.mctreasurer.org/TaxLien for the complete list of eligible parcels, but that address did not resolve when checked in August 2026, so request the current list from the Treasurer's office. No online bidding platform is used for this sale.

Montgomery County Sheriff's Office (Sheriff's Real Estate Sales)
Frequency
annual
Typical timing
Two separate schedules.
Sale list
Sheriff's list of properties for sale
When it runs
Two separate schedules. Online tax lien foreclosure sales, brought by third-party tax certificate holders, and mortgage foreclosure sales run weekly: "Tax Lien Sales sales are scheduled every Friday and start promptly at 9:00 AM Eastern Time (EST)." In-person Treasurer's Tax Sales run monthly: "In-person auctions will occur at 10 AM EST, the first Thursday of every month at The Montgomery County Administration building 451 W. Third St. Dayton, Ohio, 45422, lower level auditorium."
Registration and deposit

For the Friday online sales, register at the RealAuction site and post a per-property deposit before the auction. Tax lien foreclosure sales require $1,000 plus transfer and recording fees of $47.50 plus $0.50 for each additional parcel. Mortgage foreclosure deposits scale with appraised value: $2,000 at or under $10,000, $5,000 above $10,000 through $200,000, and $10,000 above $200,000. Deposits must be bank wire or ACH; RealAuction accepts no cash. Wires must arrive by 5 p.m. ET two business days before the sale, and ACH must be initiated by 4 p.m. ET five business days before. For the in-person monthly Treasurer's Tax Sale, the winning bidder deposits $1,000 plus the same transfer and recording fees immediately after the sale, payable by cash, certified check, or a local personal check with photo ID signed in the office. Bidder training and platform support: RealAuction at (877) 361-7325.

Sale format and venue
The Sheriff moved all foreclosure real estate online on January 7, 2022 under the RealAuction contract with the Ohio Department of Administrative Services, and added tax lien sales to the platform on June 10, 2022. Important split: the monthly Treasurer's Tax Sale is still conducted in person at the county administration building and is not bid through the online platform, so plan to attend. Mortgage foreclosure sales open at two thirds of the appraised value with $100 minimum increments. Balance of the purchase price is due to the Sheriff by certified or cashier's check within 15 days of the confirmation entry for tax lien sales and Treasurer's tax sales, and within 30 days for mortgage foreclosures; missing the deadline risks contempt proceedings and loss of the deposit. Deeds are transferred and recorded within 14 days of the Sheriff receiving the deed, confirmation entry, and final payment. Sales are advertised in the Dayton Daily News for at least three consecutive weeks. Property is sold as is, caveat emptor, with no interior inspection and no keys; buyers must research back taxes, utility bills, and other liens themselves. The Sheriff's Office does not mail out property lists. Occupied properties require a Writ of Possession filed through the Clerk of Courts. Sheriff's Real Estate Sales phone: (937) 496-3065.

Montgomery County tax sale list and auction calendar

For Montgomery County tax sale 2026 searches, use the county-run sources below rather than a copied parcel list, and confirm the parcel, registration cutoff, deposit, and payment deadline against the county before you bid.

  1. Get the advertised list

    Use Sheriff's list of properties for sale for the current advertised parcels, then recheck it before the auction.
  2. Register to bid

    Ask the county office how and when to register; many counties close registration days or weeks before the sale.
  3. Sale day

    Two separate schedules. Bidding runs on RealAuction; check posted sale dates, registration status, and bidding windows there.
  4. Confirm with the office

    If the list, platform, and notice disagree, use Montgomery County Sheriff's Office (Sheriff's Real Estate Sales) as the source to confirm which parcels are actually offered.

Before you bid in Montgomery County

  1. Start with the live sale list

    Pull the current advertised parcels from Sheriff's list of properties for sale. Lists can change before the sale, so recheck the county source before you price a parcel.
  2. Confirm registration and deposit

    For the Friday online sales, register at the RealAuction site and post a per-property deposit before the auction. Tax lien foreclosure sales require $1,000 plus transfer and recording fees of $47.50 plus $0.50 for each additional parcel. Mortgage foreclosure deposits scale with appraised value: $2,000 at or under $10,000, $5,000 above $10,000 through $200,000, and $10,000 above $200,000. Deposits must be bank wire or ACH; RealAuction accepts no cash. Wires must arrive by 5 p.m. ET two business days before the sale, and ACH must be initiated by 4 p.m. ET five business days before. For the in-person monthly Treasurer's Tax Sale, the winning bidder deposits $1,000 plus the same transfer and recording fees immediately after the sale, payable by cash, certified check, or a local personal check with photo ID signed in the office. Bidder training and platform support: RealAuction at (877) 361-7325.

  3. 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.
  4. 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

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.

County notes

  • Montgomery County runs both Ohio paths, but only the deed path is open to individual bidders. The Treasurer's annual tax certificate sale is a negotiated block sale under Ohio Rev. Code 5721.33, and the county states certificates are not available for purchase individually.
  • Retail investors who want Montgomery County tax-delinquent real estate buy at the Sheriff's sales: weekly online tax lien foreclosure auctions on RealAuction, or the monthly in-person Treasurer's Tax Sale.
  • Three distinct sale types share the Sheriff's auction list: mortgage foreclosures, tax lien foreclosures brought by certificate holders, and Treasurer's tax sales. Confirm which type a parcel falls under before bidding, because deposit amounts and payment deadlines differ.
  • The Treasurer's office directs delinquency and foreclosure sale questions to 937-225-4010, option 2, or [email protected]. The Sheriff's real estate sales desk is a separate contact at (937) 496-3065.
  • County contacts and departments sit under the mcohio.org domain. The older mctreas.org address now redirects to https://www.mcohio.org/mctreas.

Ohio rules

Max interest rate
18% per year, bid down in 0.25% steps
Minimum return
6% floor at redemption
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.
Governing statute
R.C. Chapter 5721

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.
