Is the Zestimate Accurate for a DeSoto, TX Home?

Last updated October 8, 2026

Zillow reports a nationwide median error of 1.94% on homes listed for sale and 7.06% on homes that are not. A typical off-market DeSoto home carries a Zillow index value of $320,428, so a 7% miss is about $22,600. Zestimate is a starting point. A walk-through is the number.

Zillow's own DeSoto number is a fine place to start the conversation. It is a bad place to end it. Here is what the Zestimate gets right, what it cannot see, and what to use before you pick a list price.

How accurate is the Zestimate for a DeSoto home?

Zillow publishes its accuracy as a nationwide median error rate. As reported by The Close from Zillow's March 2025 data, that is 1.94% for on-market homes and 7.06% for off-market homes. Those are national medians, not DeSoto figures. A median also means half of off-market homes miss by more than 7.06%.

The DeSoto inputs are Zillow's own. Its home value index put the typical DeSoto home at $320,428 on August 31, 2026, down 1.4% from a year earlier. Median days to pending was 20 on the same date, and the median sale-to-list ratio was 0.999 as of July 31, 2026. Those numbers describe the middle of the market. They do not describe your kitchen, your lot, or your street.

Why does the Zestimate miss on a home that is not listed?

A model cannot see inside your house. It does not know about the 2023 roof, the original carpet, or the foundation work you finished in the spring. It also works with thin sale-price data. Texas does not require sale prices to be recorded in public records, so a model has less to learn from here than in states that publish them.

Once a home is listed, an agent adds photos, condition, and a list price, and the error drops. That is why the on-market median is 1.94% and the off-market median is 7.06%. The gap is the missing information.

Your appraisal district value is a separate number. The Dallas Central Appraisal District sets values for tax purposes as of January 1. It is not a list price either.

What does a 7% miss cost a DeSoto seller?

Take Zillow's $320,428 DeSoto index value and apply its two national median error rates. This is arithmetic, not a prediction for your home.

Error rate	Applied to $320,428
1.94% (on-market median)	about $6,200
7.06% (off-market median)	about $22,600

Price too high and your home sits. HAR.com showed 247 homes for sale in DeSoto in October 2026, so a buyer has options. Price too low and the money is gone at closing. Either direction costs you. You can read how the same problem plays out in Duncanville, where the pattern is the same.

What should you use instead of a Zestimate to price a DeSoto home?

Use a walk-through. A comparative market analysis built from homes that closed near you, adjusted for what is different about your house, is the number a buyer's appraiser will test. Three things move it most: condition, updates, and the street you are on. A model scores none of them from the curb.

FAQ

Can I list my DeSoto home at the Zestimate?

You can, but it is a guess with a 7% median error attached. Price from closed comparable sales and your home's condition instead. Then use the Zestimate only to understand what buyers see online.

Is my Dallas County appraisal the same as my home's market value?

No. The appraisal district estimates value for property tax as of January 1. A buyer pays what the market supports on the day you sell.

Does a Zestimate know my home's last sale price in Texas?

Often it does not. Texas does not require sale prices to be recorded publicly, so the model works with less data than in states that publish them.

How fast are DeSoto homes going under contract?

Zillow showed a median of 20 days to pending on August 31, 2026. Your home may take more or less time, depending on price and condition.
