Redfin says my McKinney home would go pending in 44 days but Zillow and Movoto show homes sitting for over 130 — which days-on-market number should I actually trust before I set my list price?

Redfin says my McKinney home would go pending in 44 days but Zillow and Movoto show homes sitting for over 130 — which days-on-market number should I actually trust before I set my list price? None of them, exactly. Each site pulls and calculates data differently, so the only number worth trusting is a hyperlocal, MLS-verified figure for homes like yours in McKinney and Collin County.

If you've been researching your home's value online, you've probably noticed this exact problem: open three different real estate portals and you get three wildly different pictures of how fast homes are actually selling. One site makes it look like you'll have a contract in six weeks. Another makes it look like your house could sit through an entire season. That's not a glitch — it's a data methodology problem, and it trips up sellers across McKinney, Prosper, Frisco, and every other fast-growing Collin County suburb.

The gap usually comes down to three things: what counts as "days on market" in the first place, how far back and how wide the geographic sample is, and whether the number reflects your specific price point, home style, or neighborhood versus a broad citywide average that lumps together everything from a starter home in an older McKinney subdivision to a new build in Trinity Falls. A single citywide average can hide enormous swings between a well-priced home in Stonebridge Ranch and an overpriced one on the same street.

Before you anchor your list price to any of these third-party numbers, it helps to understand exactly why they disagree, what each one is actually measuring, and how to pull a number that reflects your real competition — not a national algorithm's best guess.

Why Redfin, Zillow, and Movoto Don't Agree

Every major portal licenses data from local MLS feeds, but they don't all process it the same way. Some sites reset the days-on-market clock when a listing is relisted or the price is changed, while others carry the original list date forward no matter what happens to the listing in between. That single difference alone can turn a 44-day number into a 130-day number for the exact same set of homes.

There's also a timing issue. Redfin tends to update quickly and often highlights more current, active-market behavior, while some aggregator sites like Movoto pull from broader or slightly delayed datasets that blend in older listings, expired listings, or homes that were pulled off and relisted. Zillow's own "days on Zillow" metric is notorious for not matching what's actually in the MLS, partly because it counts differently and partly because it doesn't always reflect status changes fast enough.

The Averaging Problem

Even when the math is done correctly, these sites usually report a single average for an entire city or zip code. McKinney spans a huge range of home styles and price points — a resale home near downtown, a golf-course property in Stonebridge Ranch, and a new-construction home in Trinity Falls or Painted Tree do not sell on the same timeline. Averaging them together produces a number that's technically accurate for no specific house.

This is the same reason two neighbors on the same street in Craig Ranch can see completely different online estimates of how fast a similar home would sell. The algorithm doesn't know your home's condition, your specific lot, or how it compares to the three houses that are actually competing with you right now.

What Days on Market Should Actually Tell You

Days on market, done correctly, answers one question: how long did it take similar homes, in your specific neighborhood and price range, to go from active to pending? That's it. It's a competitive benchmark, not a prediction, and it's only useful when the comparison set is tight enough to mean something.

• Homes in the same school zone and neighborhood, not just the same city
• Homes in a similar price band, since $450K homes and $850K homes move differently
• Homes that closed or went pending recently, not six months ago before rates or inventory shifted
• Listings that weren't quietly relisted to reset the clock

On that last point, it's worth knowing that some listings you see online with a fresh listing date have actually been on and off the market before. If you want to understand how that affects the numbers you're seeing, this post digs into why so many McKinney listings show "back on market" with a brand-new listing date and how to check a home's real history before you rely on its stats.

Why This Matters More Than Ever Right Now

McKinney and the surrounding Collin County market have shifted over the past couple of years, with more new construction competing for buyer attention in areas like Trinity Falls, Painted Tree, and Light Farms. That competition can push resale days-on-market numbers up in some pockets while leaving others largely unaffected. A citywide average smooths all of that out and can leave you pricing your home based on a trend that doesn't actually apply to your street.

How to Get a Number You Can Actually Rely On

The only way to know how fast your home will realistically sell is to look at true comparables: closed and pending sales within your neighborhood, in a similar price range, from the last 90 days, pulled directly from the MLS rather than a third-party estimate. That data exists, but it's not something the public-facing portals surface cleanly.

FAQ

Why do Zillow and Redfin show different days-on-market numbers for the same city?

They use different methodologies for what counts as the start and end of a listing's time on market, different update speeds, and sometimes different geographic sample sizes, which can produce very different averages even for the same area.

Is a lower days-on-market number always better for pricing my home?

Not necessarily. A short average can reflect an undersupplied price range or an unusually hot pocket of the market, while a longer average might just reflect a broader, less relevant sample. The number only matters in context of your specific neighborhood and price band.

Should I price my McKinney home based on a citywide average?

No. Citywide averages blend together very different neighborhoods, home styles, and price points across McKinney and Collin County, so they rarely reflect what will actually happen with your specific home.
