What do these Union County numbers mean for buyers and investors?

Union County, Ohio currently has 1 property in active tax delinquency as of the data snapshot. While this is a modest count, the broader distress signal is much clearer: the county is experiencing meaningful upstream pressure. In the same timeframe, there are 7 properties in preprobate status, 5 in preforeclosure, and 4 already in active foreclosure. Additionally, 1 property carries a Notice of Default, 1 is subject to a state lien, and 1 has a mechanic lien attached. These concurrent distress events across the county suggest that properties are moving through various stages of financial trouble, and tax delinquency is only one part of a broader pattern of owner difficulty.

For buyers and investors, this environment presents both opportunity and caution. A low absolute count of tax-delinquent properties means less competition at auction, but it also signals that properties reaching that final stage are relatively rare in Union County. The presence of multiple foreclosures and preforeclosure cases suggests that mortgage default is outpacing property tax default in this market, which is typical. However, the mix of probate, divorce, and lien activity indicates that estate settlements, marital dissolution, and creditor claims are all factors driving property distress simultaneously. An investor or owner-occupant buyer should expect that any tax-delinquent property acquired in Union County will likely require careful title work and possibly negotiation with other lienholders or claimants.

How to get the official Union County, Ohio tax-delinquent list

The County Treasurer of Union County, Ohio is the authoritative source for the tax-delinquent property list. The Treasurer's office is the place to ask about properties that have not paid property taxes and may be subject to foreclosure or sale.

To access the list, follow these steps:

• Contact the County Treasurer directly by phone, mail, or in person at their office in the Union County Courthouse.
• Request the current "tax-delinquent properties list" or "delinquent tax roll."
• Ask whether the list is available online via the county website, or if you need to visit in person to view it.
• Inquire about the publication schedule: how often the list is updated and whether new additions are announced before the next tax sale.
• Request notification of upcoming tax sale dates and the location and time of the sale.

Many county treasurers now maintain searchable databases or publish delinquent lists on the county's official website. Union County's Treasurer may offer electronic access; confirm this when you first contact the office. The list typically shows the property address, the amount of delinquent tax (Oklahoma example) owed, penalties and costs, and sometimes the estimated auction price. Keep records of all inquiries and dates, as these will help you track when properties are added to or removed from the delinquent roll.

How Ohio's tax sale and redemption process works

Sale type, redemption rights and interest are set by Ohio law and the county's own procedures; confirm them with the Union County Treasurer before bidding. The process starts when property taxes go unpaid beyond a set deadline, and the county then follows the notice, legal action and sale steps that Ohio law requires; ask the Treasurer how long that takes in Union County and how often sales are held.

At a tax sale (see this Oklahoma tax sale auction guide for a general example), bidders may be required to pay the opening bid amount (the delinquent taxes, penalties, and costs) and any additional bid amount on the spot or within a specified period. Ask the Treasurer who conducts the sale.

Ask the Union County Treasurer whether a former owner or other interested party can redeem, for how long and at what cost, and when a buyer receives title. Redemption terms are set by Ohio law and the county's procedures, and they affect when your investment is secure, so confirm them before bidding.

Ask the Treasurer and an Ohio real estate attorney how and when a buyer receives a deed, and which liens or claims (for example federal tax liens or homestead rights) would remain.

What due diligence and risks apply before bidding in Union County?

Purchasing a tax-delinquent property in Union County requires thorough investigation before you commit money at auction.

Title and liens: Order a current title search or abstract immediately. Do not assume a tax sale clears liens or ends redemption rights. A title report will reveal mechanic liens (like the 1 currently on file in the county), state tax liens, federal tax liens, homestead claims, and judgment liens. Which of these survive a tax sale is a question for counsel. Consult a real estate attorney to understand which liens will clear and which the buyer will inherit.

Property condition and occupancy: Conduct a physical inspection if possible. Tax-delinquent properties are often distressed and may be vacant, occupied by the defaulted owner, or occupied by a tenant. Identify whether the property is structurally sound, has code violations, or requires significant repairs. Verify occupancy status and whether anyone has a right to remain on the property. Occupancy and habitability issues can delay your ability to take possession or generate unexpected liability.

Environmental and municipal liens: Check for code enforcement liens, stormwater liens, and any local government claims against the property. These may not appear on the title report but could be enforced against you after purchase. Contact the Union County Auditor and the relevant township or city assessor to confirm that no unpaid special assessments or violation notices are on file.

Redemption timeline: Before bidding, confirm the exact redemption period that will apply to this property. Do not assume all properties have the same redemption terms. Any redemption period delays clear title and the right to occupy or sell.

Sale terms and bidding: Obtain and read the official tax sale notice and any bidding rules issued by the County Treasurer. Understand payment deadlines, earnest money requirements, and whether the sale is "as-is" with no warranties. Confirm the opening bid amount and whether you will be required to pay the full amount on the day of sale.

Frequently Asked Questions

How do I get a copy of the Union County tax-delinquent properties list?

Contact the Union County Treasurer. You can request the list by phone, mail, or by visiting the Treasurer's office at the Union County Courthouse. Ask whether the list is available online or if you must view it in person. The Treasurer can also explain the current publication schedule and notify you of upcoming tax sales.

When is the next tax sale in Union County, Ohio?

The date and frequency of tax sales are set by the County Treasurer and Ohio state law. You must contact the Union County Treasurer directly to learn the next scheduled sale date. The Treasurer will also inform you of the sale location and any specific rules or procedures that apply.

What is the redemption period in Ohio, and can I take possession before it expires?

Redemption rights after a tax sale are set by Ohio law and the county's procedures. The exact terms depend on the property and the sale, so you must confirm them with the Union County Treasurer before bidding. Do not occupy or significantly invest in the property until you know whether redemption rights remain open and you have received a deed.

Is it worth buying a tax-delinquent property in Union County?

That depends on your investment goals, risk tolerance, and local market knowledge. Low competition (Union County has only 1 property currently delinquent) can mean less bidding pressure and potentially good pricing, but the small number also means fewer opportunities. You must conduct thorough title research, property inspection, and due diligence on every property before bidding. Factor in the redemption period, potential repair costs, and any liens or code violations. Many successful investors purchase at tax sales, but each property requires individual analysis. Consult a real estate attorney and local real estate professional to evaluate whether a specific Union County property makes financial sense for you.
