What the Numbers Tell Us About Denton County, Lewisville & Flower Mound

September 2026 DFW Housing Market Update
Updated October 22, 2026 | By Sarah Roberts, Broker Associate | Mosaic Realty Group

If you've been following the housing market lately, you've probably noticed that the headlines don't always agree. One report says prices are falling, another says they're holding steady, and sometimes what you're hearing doesn't match what you're seeing in your own neighborhood.

That's why we take time each month to look at what's happening here in North Texas.

The September 2026 numbers are especially interesting. Denton County's median sold price declined 3.9% from September 2025, while Lewisville ISD's median sold price increased 6.1%.

Both numbers tell us something useful about our local market. Whether you're planning a move or simply keeping up with your home's market, understanding these differences can help you make more informed decisions.

What Happened in the DFW Housing Market in September 2026?

Across Denton, Dallas, Collin, and Tarrant counties, median prices and inventory levels showed different trends. Here's a quick look at the four counties.

While Denton and Collin counties recorded lower median prices than a year earlier, Dallas County saw a small increase and Tarrant County remained unchanged.

Inventory ranged from 3.6 months in Tarrant County to 4.6 months in Dallas County. These differences remind us that DFW isn't one uniform housing market.

A Closer Look at the Other DFW Counties

What's Happening in the Denton County Housing Market?

Now let's look a little closer to home. Denton County recorded more active listings and fewer closed sales compared with a year ago.

With more active listings and fewer completed sales, buyers may have additional properties to compare. For sellers, understanding how a home competes with similar listings is especially important.

Pricing, presentation, property condition, and location all play a role in how a home performs on the market.

Why Does Lewisville ISD Look Different From Denton County?

This is one of the most interesting comparisons in September's report.

How can two areas in the same region show such different results?

Lewisville ISD spans portions of multiple North Texas communities. Its reporting boundaries and mix of sold properties differ from Denton County as a whole.

The size, type, location, and price range of homes sold can all influence the median. That's why looking at your immediate neighborhood is often more useful than relying on a broad market headline.

Lewisville ISD Housing Market: September 2026

These statistics give us a more focused picture of the local market, but individual neighborhoods can still look very different. Let's compare a few ZIP codes in Lewisville and Flower Mound.

How Do Lewisville ZIP Codes 75067 and 75077 Compare?

The September numbers show very different median sold prices in these two Lewisville-area ZIP codes, even though inventory and days on market were nearly identical.

Despite their different median prices and year-over-year changes, both ZIP codes had 3.4 months of inventory. Their median days on market differed by only one day.

With 34 and 36 closed sales, the mix of homes sold can have a noticeable effect on monthly medians. For someone planning a move in Lewisville, recent comparable sales in the specific neighborhood provide a more useful starting point.

What's Happening in the Flower Mound Housing Market?

Flower Mound offers another example of why local market details matter.

ZIP code 75022 had a higher median sold price but also more months of inventory than 75028. This difference can influence the number of available options and the level of competition buyers and sellers experience.

With only 15 closed sales in 75022 during September, it's especially important to consider the mix of homes sold before drawing conclusions from the median-price change.

What Do These Numbers Mean for DFW Homebuyers?

More Inventory May Mean More Choices

In some areas, buyers have more properties to compare than they did a year ago. Depending on the home and seller's circumstances, there may also be opportunities to discuss repairs, closing costs, or other offer terms.

Focus on Your Monthly Payment

A home's asking price is only one part of the financial picture. Mortgage rates, property taxes, homeowners insurance, maintenance, and other costs all affect affordability.

Understanding your total monthly payment can help you choose a home that works for your budget and longer-term plans.

Compare the Neighborhoods You're Considering

The price points and available homes in Lewisville 75067 may look different from those in 75077 or Flower Mound. Knowing the local numbers helps you set realistic expectations before beginning your search.

What Should DFW Home Sellers Know Before Listing?

Two Lewisville ISD statistics are especially useful for homeowners considering a sale.

The 94.8% ratio compares final sale prices with original listing prices across transactions. It doesn't mean every home sold for 5.2% below its final asking price, and it doesn't predict what any individual home will sell for.

Pricing Should Reflect Today's Competition

A home that sold last year can provide useful context, but recent comparable sales and current listings are important when choosing a listing price.

Preparation Makes a Difference

Not every home needs major improvements. Sometimes maintenance, smaller updates, thoughtful presentation, and good marketing can help buyers see a home's value.

Your Timeline Matters

Someone who needs to sell and buy another home within a specific timeframe may need a different strategy from someone planning a move a year or two from now.

The right plan should account for your home, your financial goals, and what comes next.
