Collin County Home Values Dip

Yes. The average home value in Collin County dropped from $603,190 in 2025 to $588,119 in 2026, according to the Collin Central Appraisal District's certified values released July 23. At the same time, the county's total taxable property value grew 4.43%, driven mostly by new construction in fast-growing areas like Celina and Melissa.

Every year around this time, my phone starts ringing with the same question: did my home lose value? This year the answer for a lot of Collin County homeowners is technically yes, and the reason why is actually good information to have.

The Collin Central Appraisal District released its 2026 certified taxable values on July 23. Brian Swanson, the district's deputy chief appraiser, put it plainly: the overall value of the county grew 4.43%, but the average home value actually dropped, from $603,190 in 2025 to $588,119 in 2026.

Those two numbers moving in opposite directions is not a contradiction. It's new construction. Collin County added $7.7 billion in new property to the tax rolls this year, most of it concentrated in Celina, Melissa, and the east side of the county around Lavon, Nevada, and Princeton. New rooftops grow the total tax base even while existing home values level off or dip slightly after a few years of unsustainable appreciation.

If you're a seller, this matters. The 2021 and 2022 comps are gone. Pricing a listing off what your neighbor got three years ago is the fastest way to sit on the market. Buyers today have more inventory and more leverage, and they know it.

If you're a buyer, a countywide dip in average values plus more inventory means more room to negotiate, whether that's on price, closing costs, or repairs after inspection.

And if you're a homeowner just trying to figure out your tax bill, remember that your appraised value and your actual tax bill are two different conversations. A lower home value doesn't automatically mean a lower bill if your city or school district adjusts its tax rate. It's worth watching your notice closely and knowing your protest deadline.

I walk clients through exactly what their specific ZIP code and school district are doing every week, because countywide averages only tell part of the story.
