DFW Housing Market Update | August 2026

Are Home Prices Up or Down?

The short answer is: it depends on where you look.

In August, median home prices were up year over year in Denton and Collin Counties, essentially flat in Dallas County, and down in Tarrant County.

And when we look closer at Denton County, the differences become even more noticeable. Denton County, Lewisville ISD, and two neighboring Lewisville ZIP codes all tell slightly different stories.

That’s why a DFW-wide headline can give us context, but it may not describe what’s happening in your specific neighborhood, price range, or type of home.

In this market update, Mosaic Realty Group looks at the August 2026 numbers for Denton, Dallas, Collin, and Tarrant Counties, with a closer look at Lewisville ISD and ZIP codes 75077 and 75067.

DFW Housing Market at a Glance — August 2026

Here’s how the four counties compare.

The important takeaway isn’t simply which counties were up or down.

There wasn’t one direction for the entire DFW housing market in August.

And that becomes even clearer when we look closer at Denton County.

What is happening in the Denton County housing market?

In August 2026, the median home price in Denton County was $440,000, up 1.2% compared with August 2025.

There were 1,233 closed sales, 5,412 active listings, and 4.5 months of inventory.

Denton County | August 2026

Those numbers give us a useful picture of Denton County as a whole.

But Denton County covers many different communities, including Lewisville, Flower Mound, Highland Village, The Colony, and Little Elm. What’s happening in one community—or even one ZIP code—may look different from the county-wide numbers.

That’s where looking closer becomes useful.

What happens when we look closer at Lewisville?

Lewisville ISD tells a different story from Denton County as a whole.

The median home price across Lewisville ISD was $500,000 in August, down 3.5% compared with the previous year.

Then we can narrow the data even further.

Same general area. Same month. Different numbers.

This doesn’t mean one ZIP code is doing “better” than the other. We’re looking at different groups of homes, price points, neighborhoods, and sales activity.

There’s another important piece of context here: only 39 homes closed in 75077 and 32 in 75067 during August.

With a smaller number of sales, monthly median prices can move around more. That’s why we use ZIP-code statistics for context rather than treating one month as a prediction of where prices are headed.

Are Denton County home prices going up or down?

At the county level, the August 2026 median price was up 1.2% compared with the previous year.

But that does not mean every Denton County home increased in value by 1.2%.

The Lewisville example shows why.

A home’s value can be influenced by its neighborhood, property type, condition, size, features, price range, recent comparable sales, and current competition.

If you’re wondering what your own home may be worth, county-wide data is a starting point. Looking at the homes actually competing with and selling around yours provides much more useful context.

What happened in Dallas, Collin, and Tarrant Counties?

Dallas County

The median home price in Dallas County was $365,000 in August 2026, essentially unchanged from August 2025.

Collin County

The median home price in Collin County was $463,203, up 0.7% year over year.

Tarrant County

The median home price in Tarrant County was $340,000, down 2.9% from August 2025.

Together, the four counties reinforce the same point:

There isn’t one number that describes every DFW housing market.

What do recent interest-rate changes mean for DFW homebuyers?

Interest rates matter because mortgage rates affect a buyer’s monthly payment and purchasing power.

One important distinction is that the Federal Reserve does not directly set mortgage rates. A change in the federal funds rate does not automatically mean mortgage rates will change by the same amount.

For someone considering buying a home, it can be more useful to ask:

• What would my monthly payment look like?

• What price range feels comfortable for my budget?

• What homes are available in that range?

• How much competition is there where I’m looking?

• What options may be available with the particular home?

Instead of trying to predict exactly where rates will go next, bring the question back to your own plans:

Does this home and this payment make sense for me right now?

Is it a buyer’s or seller’s market in DFW right now?

There isn’t one answer that applies equally to every part of DFW.

In August, the four counties in this update ranged from 3.6 months of inventory in Tarrant County to 4.5 months in Denton and Dallas Counties.

But even county-wide inventory doesn’t tell us everything. Conditions can vary by city, neighborhood, price range, and property type.

A buyer may experience more competition for one type of home while finding more choices somewhere else.

For sellers, the same principle applies. Your competition isn’t every home in DFW. It’s the homes buyers are likely to compare with yours.

What should DFW buyers take from the August numbers?

If you’re considering buying, look beyond one county-wide headline.

Pay attention to:

• What’s available where you’re actually looking

• What’s recently sold

• Competition in your price range

• Your monthly payment

• The condition of the homes you’re considering

• The terms available with a particular property

Depending on the home and local market, there may be more room for conversation around price, repairs, closing costs, or other terms. Another neighborhood or price range may have more competition.

The numbers give us information. They don’t make the decision for you.

What should DFW sellers take from the August numbers?

If you’re thinking about selling, don’t assume a county-wide percentage represents the change in your individual home’s value.

Instead, look at:

• Recent comparable sales near your home

• Homes currently competing for buyers

• Your home’s condition and features

• Pricing

• Your neighborhood and price range

• Your plans for the move

Preparation may include paint, small repairs, cleaning, staging, or simply making sure the home shows well.

It doesn’t automatically mean you need to take on a major renovation.

The goal is to understand your local competition and determine what makes sense for your home and your plans.

What’s happening closer to home?

The August numbers show why it helps to move from the big picture to the local one:

DFW → County → City → ZIP Code → Neighborhood → Your Home

A market statistic is information. It isn’t an instruction to buy, sell, or wait.
