How Accurate Is a Zestimate in Triple Crown in Union, Kentucky?
Why online home value estimates for Triple Crown can miss by tens of thousands of dollars, what they can't see, and how to get a price you can list at.
Key takeaways
- Online estimates such as the Zestimate are automated valuations built from public records, past sales and listing data. Nobody looks at your home.
- Their error is largest for homes that are not listed for sale, and for homes with updates or features the records don’t show.
- On a home near the Triple Crown median of $597,500, a miss of a few percent is a five-figure difference.
- Use an estimate as a starting point only. Set the list price from a comparative market analysis built by a local listing agent.
How online estimates work
Automated valuation models, the technology behind the Zestimate and other online estimates, start from public records: square footage, bedrooms, bathrooms, lot size, year built and the last sale price. They compare those facts with recent sales nearby and apply a statistical model.
Zillow publishes its own accuracy figures (zillow.com/z/zestimate), and its error is noticeably larger for homes that are not listed for sale than for homes that are, because a listing adds photos, a description and an asking price for the model to learn from.
What an online estimate can’t see
- Condition: a refreshed kitchen and a 1990s original look identical in public records.
- Finished basements, which are often missing or wrong in county records.
- A new roof, windows, HVAC or water heater.
- Which floor plan you have, in subdivisions where several plans share similar square footage.
- The lot itself: backing to woods versus a busy road, a flat yard versus a steep one.
- What is for sale against you this week, and how fast it is selling.
Why the miss matters in Triple Crown
The Triple Crown resale median was $597,500 in July to September 2026. An estimate that is 5% high on a home like that is about $30,000 too high, enough to cost weeks on the market. One that is 5% low hands the same amount to the buyer.
Sellers who list at an online estimate that runs high usually end up reducing. Sellers who list at one that runs low often see a fast sale and never learn what they left behind.

Why buyers quote the Zestimate, and how to answer
Buyers and their agents sometimes point to a low online estimate during negotiation. The answer is the evidence: the closed sales your price is built on, the updates the estimate doesn’t know about, and the appraisal the buyer’s lender will order. A listing agent brings that evidence to the table for you.
Getting a price you can list at
- Look at a rangeUse an instant report built from recent local sales, not a single number, as the first look.
- Have an agent see the homeA walk-through captures condition, updates and the lot, which change value more than online tools allow.
- Review the comparablesAsk to see every sale used and the adjustment made for each. A good pricing review shows its work.
- Set the price with a planAgree the list price and the points at which you will review feedback before you go live.
Questions sellers ask
Is the Zestimate accurate in Triple Crown?
It can be close for typical homes with accurate records, but it does not see condition, updates, finished basements or the lot, and its error is larger for homes that are not for sale. Treat it as a starting point, not a list price.
Why is my Zestimate different from my agent’s price?
The estimate is an automated model built on public records. An agent’s price comes from walking through the home and adjusting recent comparable sales for its actual size, condition, updates and lot.
Can I get my Zestimate changed?
Owners can update home facts on Zillow, which can change the estimate, but a different online number does not change what buyers and appraisers will pay. The price that matters is the one supported by comparable sales.
