Union County at a glance

Population: 73,677
Median home (2024) Median home (2024) The midpoint value of owner-occupied homes — half the county's homes are worth more, half less. Source: the Census Bureau's American Community Survey 5-year estimates (table B25077), which reflect what owners estimate their home is worth, not sale prices. The year shown is the most recent one published.: $344,900
Assessment ratio (2021) Assessment ratio (2021) How close the county auditor's appraised values are to what homes actually sell for. The Ohio Department of Taxation compares the auditor's appraised value to the real sale price on arm's-length sales and publishes a median ratio for each city and township; this figure combines those into one county number, weighted by each area's number of sales. 100% means appraisals matched sale prices. 75% means the typical home was appraised at about three-quarters of what it sold for; above 100% means the typical home was appraised for more than it sold for. It describes the county as a whole — any individual property can be far off it. (Ohio bills tax on 35% of appraised value; that 35% is fixed by statute and is not what this ratio measures.): 72.98%
Median income: $109,506
School districts: 3
Last Reappraisal Last Reappraisal Ohio counties reappraise every property every six years, with a lighter 'update' three years in between (ORC §5713.01). The values set in that year drive tax bills until the next one. Dates come from the Ohio Department of Taxation's published sexennial reappraisal and triennial update schedule.: 2025
Next Update Next Update Ohio counties reappraise every property every six years, with a lighter 'update' three years in between (ORC §5713.01). The values set in that year drive tax bills until the next one. Dates come from the Ohio Department of Taxation's published sexennial reappraisal and triennial update schedule.: 2028

Why are 2019–2021 cases mostly still active? Ohio's COVID-19 emergency orders (beginning March 2020) imposed a foreclosure moratorium that paused most delinquent tax lien proceedings for over a year. Cases filed before and during the freeze accumulated in county courts and many are still working toward a final outcome — either a sheriff sale or a dismissal once the homeowner resolves the debt.

Why do some rows below show a dash (—)? Finding out whether a case was lost to sheriff sale, dismissed, or is still pending requires opening and reading each individual court case one at a time — it isn't reported anywhere as a simple summary number. We are actively working through this county-by-county for all Ohio counties. A dash means we don't have that breakdown yet, not that the outcome was zero.

Why does Assessment Ratio have gaps? The Ohio Department of Taxation only publishes this figure for years when Union County underwent its sexennial reappraisal or triennial update — not every year in between. A dash means no study was conducted that year, not that the county was accurately assessed.

Treasurer Filed Foreclosures Treasurer Filed Foreclosures Tax lien foreclosure cases the county Treasurer filed against properties with unpaid property taxes — usually brought by the county Prosecutor on the Treasurer's behalf. Counted from the county's own court records, year by year; the source is linked below this table.	2	2	5	2	2	3	2	5	2	3	3
3rd Party Investor Filed Foreclosures 3rd Party Investor Filed Foreclosures Foreclosure cases filed by a third-party investor — a private company that bought delinquent tax liens from the county and then went to court to collect on them. Ohio counties may sell tax liens this way under ORC §§5721.30–5721.43, and once sold it is the investor, not the county, that files the case.	—	—	—	—	—	—	—	—	—	—	—
Lost to Sale Lost to Sale Cases that ended with the property sold at sheriff's sale — the owner lost the home. This can only be determined by reading each case on the court docket, so a dash means we don't have that breakdown for the year yet, not that the number was zero.	—	—	—	—	—	—	—	—	—	—	—
Dismissed Dismissed Cases closed without a sheriff's sale — typically because the owner paid off the delinquent taxes or worked out a payment plan. Also read case by case from the docket.	—	—	—	—	—	—	—	—	—	—	—
Pending Pending Cases filed but not yet resolved by a sheriff's sale, dismissal, or other closure — still working their way through the court system. Where the court publishes a case status we use it directly; otherwise this is that year's filings minus the cases lost to sale and dismissed.	—	—	—	—	—	—	—	—	—	—	—
% Lost % Lost Lost to Sale divided by Treasurer Filed Foreclosures for the same year, rounded to a whole percent. A case filed one year may not sell until a later one, so read this as that year's rate rather than the eventual fate of that year's exact cases.	—	—	—	—	—	—	—	—	—	—	—

About this data: Data obtained from the Union County Clerk of Courts' online case search, reflecting foreclosure cases filed by the Union County Treasurer, 2015–2025. Median home value for 2025 is not available: the Census Bureau's American Community Survey 5-Year Estimates (the source for this row) had not yet published that vintage as of this data's retrieval date. Assessment ratio data is not available for 2022-2025: neither of the Ohio Department of Taxation's sales-ratio studies (SRD04 or the archived PS1&2) covers those year(s) for this county.

Source: Union County Clerk of Courts (Civil/Plaintiff case type). These are property tax lien foreclosures only — not mortgage foreclosures.

Assessment ratio: Ohio Department of Taxation, SRD04 — Residential Sales Statistics by Political Subdivision (2020–present) and PS1&2 — Sales Ratios of Real Property, By Class of Property and County (2015–2018, archived).
