Two buyers pull up listings in Union, Kentucky on the same afternoon. Both are looking at a home near $440,000. One is touring a condo with a shared roofline and an HOA that handles the mowing. The other is walking a driveway on Triple Crown Boulevard, past a fenced meadow, toward a house on a golf course lot. Same city. Same rough price point. Nothing else about the transaction is close to the same.
That's the problem with treating Union's median sale price as a shopping tool. The number is real. What it represents is not one market, it's two, stitched together by an average that has no idea it's averaging.
Why the median moves the way it does
Union isn't a high-volume market. In February 2026, only 6 homes sold in the city, according to Redfin's tracking, down from 8 the year before. That same data set showed the median sale price at $442,000, up 9 percent year over year, and average days on market jumping from 43 days to 206 days.
Read that days-on-market swing on its own and it looks like the bottom fell out of buyer demand. It didn't. With a sample size of 6 closings, one home that sat on the market for eight months before finally selling can drag the average from a brisk 43 days to a sluggish 206 without any change in how buyers actually feel about Union. A market this thin doesn't behave like a market with hundreds of monthly transactions. It behaves like a small dataset, which means a single outlier sale, a single stale listing that finally closes, a single luxury property that took longer to find its buyer, can rewrite the headline number entirely.
This is the part a portal search doesn't explain. The median and the days-on-market figure you see for Union aren't describing a trend. Most months, they're describing whichever handful of homes happened to close.
Two products, one zip code
Set the volatility aside for a moment and look at what's actually for sale. Union's housing stock splits into two categories that don't compete with each other and shouldn't be compared on price per square foot alone.
| Attached, low-maintenance product | Site-built single-family | |
|---|---|---|
| Example communities | Harmony Bluffs, Ballyshannon | Triple Crown Country Club, standard subdivisions |
| Typical price range | Roughly high-$200s to $480,000 | $500,000 to $1 million or more |
| What's included | HOA-maintained exteriors, mowing, sidewalks and often a pool or community center | Private lot, no shared maintenance, in Triple Crown's case golf course frontage |
| Square footage | Often in the 1,300 to 2,100 range | Typically larger, especially on golf course or wooded lots |
Harmony Bluffs, built by Drees Homes, markets its Atwood floor plan at $305,000 for 1,379 square feet with a rear-entry two-car garage, and the community leans on proximity to Kroger Marketplace and Union Promenade as part of the pitch. That's a fundamentally different ownership experience than a home in Triple Crown Country Club, where residents can watch horses graze along picket-fenced pastures on Triple Crown Boulevard before the road leads into the community's 18-hole golf course. Club membership isn't required to buy a home there, but the HOA structure and price tier are not the same conversation as Harmony Bluffs.
When a portal tells you the median home in Union sold for $442,000, it isn't telling you whether you're looking at a low-maintenance condo market or a golf course single-family market. It's telling you the midpoint between two markets that don't share a buyer pool.
The supply that's about to make this messier
If you're comparing Union against another Boone County suburb this fall, know that the attached side of the market is expanding. In late July and early August 2026, the Union City Commission moved forward on an ordinance approving Drees Homes' request to rezone roughly 22.2 acres at 9944 Old Union Road, between Hathaway Road and Old Union Road. The project, called Union Acres, calls for 135 total units: 29 townhomes and 106 condominiums, all for-sale product with the HOA responsible for exterior maintenance and, per city commission discussion, snow and ice removal.
That's 135 more attached units feeding into the same median that already blends condos and golf course estates. A few things worth knowing if you're timing a purchase around this:
- The rezoning moved from Agricultural Estate and Rural Suburban designations to Suburban Residential Three, a density increase the Boone County Planning Commission recommended with conditions.
- City commission minutes noted a proposed density near six units per acre, below the eight-per-acre ceiling the Boone County Comprehensive Plan allows for high suburban density residential.
- The commission has been working through site line and safety concerns raised by the Boone County Sheriff's Department before final approval.
Meanwhile, the city itself is investing in a different kind of infrastructure. Union Town Square, a 22-acre project between US-42 and Old Union Road, is under construction with a new city building, park space and a performance venue. Payments to the general contractor were still moving through review as of June 2026, and park completion is expected in early 2027. If a walkable civic center matters to your decision, that timeline, not the current listing inventory, is the thing to watch.
What this means if you're comparing neighborhoods
If your spreadsheet has Union next to Florence, Independence or another Boone County suburb, drop the median as your first filter. Ask instead which of Union's two markets you're actually shopping. An attached home in Harmony Bluffs or Ballyshannon competes on maintenance-free living and proximity to Union Promenade's retail corridor. A single-family home in Triple Crown or a standard subdivision competes on lot size, privacy and long-term resale character.
The same logic applies to school assignment, which Union buyers often assume comes bundled with a Union address. It doesn't always. Boone County Schools assigns Union-area students to a mix of campuses including Longbranch Elementary, Mann Elementary, New Haven Elementary, Ballyshannon Middle, Gray Middle and Larry A. Ryle High School, and boundaries can shift depending on the exact parcel rather than the mailing city. If school assignment factors into your decision, confirm it against the specific address, not the ZIP code.
The city is also mid-revision on its long-range Town Plan, last comprehensively updated in 2000. The draft update, reviewed through Boone County's Planning Commission process over the summer of 2026, is meant to reflect how much Union has grown since then and to formally recognize Union Town Square as a community centerpiece. It's still working through Boone County Fiscal Court approval, which means the zoning framework a buyer is evaluating today could look different by the time some of these new developments break ground.
A few questions worth asking directly
Does a Union mailing address mean the home is inside Union city limits? Not necessarily. Some communities carry a Union mailing address while sitting in unincorporated Boone County, which can affect which municipal services and zoning rules apply. Confirm the exact jurisdiction before assuming city amenities or ordinances apply.
Why did days on market look so different this year compared to last? With Union closing single digits of homes in a typical month, the days-on-market average is sensitive to whichever properties happened to sell. A slow-moving luxury listing or a stale condo finally closing can swing the average by months without reflecting a real shift in buyer demand.
Is Triple Crown Country Club membership included with a home purchase? No. Homes in Triple Crown are not sold with a required club membership, and the HOA structure varies by which section of the community you're in.
