Most coverage of the Texas housing market looks at resale: existing homes, listed by owners, bought by someone with a loan. But the builders sit next door to every one of those sales, and they are competing for the same buyer at the same mortgage rate. When their shelves are full, it changes what a renovated house down the street can fetch, and it changes what you should pay for the next flip.
The newest data on that shelf came out on October 22. HomesUSA.com’s Texas New Home Sales Report, which tracks the four major Texas markets, put September’s active new-home inventory in Dallas–Fort Worth at 8,938 listings, with new homes taking 129 days to sell. That is the longest marketing time of the four markets. This post walks through what the report says, what it does not say, and how a Texas flipper or landlord should adjust underwriting. It is an investor-facing read. If you are a homeowner weighing a sale, our companion pieces on the week’s market data are the better starting point.
What the HomesUSA report actually shows
HomesUSA’s Texas New Home Sales Report is published monthly and uses three-month moving averages, built from closed sales recorded in MLSs by the 10th of the following month. The headline numbers for September 2026, released October 22, 2026:
| Metric (September 2026) | Statewide, four major markets | Dallas–Fort Worth |
|---|---|---|
| New-home sales | 5,221 (down 7.7% from 5,658 in August) | 1,702 (down from 1,891) |
| Pending sales | 5,465 (down 7.1% from August) | 2,013 (down from 2,202) |
| Active listings | 37,056 (about flat vs. August) | 8,938 (up from 8,729) |
| Days on market | 108 (fifth straight monthly decline) | 129 (down from 132) |
| Average price | $419,016 (down 1.3% from August) | $465,663 (down from $469,398) |
| Sales-to-list price ratio | 97.81% | 97.50% |
Statewide, the report also shows new-home sales 6.2% below September 2025, pending sales 11.7% below a year ago, and an average price 2.2% below a year ago. Active listings are 0.7% lower than a year earlier. The report gives an average price, not a median, so it is not directly comparable with the median figures that resale reports use.
Read together, those numbers describe a builder market that is selling fewer homes, at slightly lower prices, from a shelf that has not shrunk. DFW is the heaviest part of that shelf: 8,938 listings is about 24% of the statewide total, in a metro that also has the slowest-moving new homes.
Why it matters even if you never buy a new build
Builders set the ceiling for renovated resale
When you flip a house, your exit is a retail buyer with a pre-approval and a choice. For many of those buyers in DFW’s suburbs, a new build is the alternative. If builders are accepting 97.5% of list and offering to cover costs, a renovated 1990s house priced near new-construction money has to win on location, lot, or price. Your ARV is a bet on what that buyer will pay, so builder inventory is a competitor to your exit.
HomesUSA’s DFW average new-home price of $465,663 is not a comp for your flip, and you should not use it as one. But it does mark the zone where a buyer starts to wonder whether to go new. As a rough orientation only: the market report we published this week cited a secondhand summary of the NTREIS report putting the North Texas single-family median at $385,000 for September, down about 1% from a year earlier. An average new-home price and a median resale price are different measures, so the roughly $80,000 spread between them is a context point, not a precise gap.
Slow new-home sales mean more motivated sellers elsewhere
Builders are not the only ones carrying costs. Owners of older houses who need to sell see the same slow market: higher rates, longer timelines, and buyers who can compare. Our Q4 investment property underwriting guide covered how a balanced market gives acquiring investors more supply to choose from. The new-home numbers reinforce it. The Freddie Mac 30-year average was 7.32% on October 22, per the weekly survey cited in our market report, against 6.19% a year earlier. On a $300,000 loan, that is roughly $225 more per month in principal and interest than a year ago, our own arithmetic. That pressure does not only hit builders. It hits every seller who needs a buyer who needs financing.
The underwriting adjustments we would make
None of this is a signal to stop buying. It is a signal to be specific about assumptions. Here is how we would adjust a Texas flip or rental model in light of this data.
1. Build ARV only from closed resale comps
Do not use list prices, builder base prices, or an averaged new-construction figure. Pull closed sales for similar condition, size, and age within a tight radius, from the most recent 90 days. If the comps are thin, widen the radius before you widen the date range. And remember that closed prices reflect concessions you will not see in the number.
2. Stress-test the ARV down
Run every deal twice: once at your comps, and once with ARV reduced by 3–5%. If the deal only works at the optimistic number, it is not a deal. Diamond’s public math is ARV × 75–80% − repairs (85–92% of ARV for clean, light-rehab tier properties), and the discount is where the margin for error lives. A worked example:
- ARV from closed comps: $300,000
- 75% of ARV: $225,000; 80% of ARV: $240,000
- Repairs: $40,000
- Maximum allowable offer range: $185,000 to $200,000
If your comps drop 5% to $285,000, the same math gives $213,750 to $228,000 before repairs, or roughly $173,750 to $188,000 after $40,000 of repairs. That is a $11,250 to $12,000 swing in the offer. A thin deal cannot absorb that; a properly discounted one can. For a fuller walkthrough, see how to run the numbers on your first Texas flip.
3. Add time to the exit, and price the carry
The report’s 129-day DFW figure is for new homes, which are marketed by professional sales teams with model homes and incentives. A renovated resale is unlikely to be faster. Underwrite at least the time to renovate, plus a realistic list-to-close window of 60 to 90 days, and price every month of that carry: loan interest, taxes, insurance, utilities. Our guide to financing a Texas flip with hard money shows how quickly points and monthly interest add up when a project runs long.
4. For rentals, compare the basis, not the label
Landlords who might be tempted by a builder discount should run the same cash-on-cash and DSCR tests they would on any property. A new build trades some repair risk for a likely higher basis. A resale or as-is purchase lowers the basis and adds renovation and insurance risk, which matters because Texas insurers are tightening on roof age. Our Texas rental property analysis guide lays out the formulas. At a 7.32% mortgage rate, thin spreads fail quickly, so test at the financing you can actually get.
What this report does not tell you
Good underwriting depends on knowing the limits of a data source. Here is what the HomesUSA release does not say:
- Incentives. The release reports a sales-to-list ratio, not the value of rate buydowns, closing-cost credits, or upgrade packages. Those can sit outside the price. Ask a builder’s sales team what is on offer in any community you are comparing against.
- Resale. It covers new homes only. Resale inventory, days on market, and price cuts come from other sources, such as the Texas Real Estate Research Center and local MLS reports. We cover those in the weekly market report.
- Neighborhood detail. DFW is a metro of several million people. A 129-day average hides communities where homes sell in weeks and those where they sit for much longer. Check the specific submarket.
- The future. One month of three-month moving averages is a trend, not a forecast. A fifth straight statewide decline in days on market is not a recovery. It could reflect slower pricing, builder discounts, or a mix shift, and the report does not say which.
What this means for sellers who are thinking of selling to an investor
If you own an older house in DFW and are watching builders discount, you are probably wondering whether your house will sell on the open market, and for how much. The honest answer is that it depends on condition and price. A house that needs significant repairs competes poorly against both new builds and updated resale. In that case, a direct cash sale can make sense: no repairs, no showings, no financing contingency, and a closing date you choose. You can compare the full math in our cash offer vs. listing breakdown, or request a no-obligation cash offer. Diamond buys for its own account as a principal. We are not real estate agents and we do not list homes.
How Diamond investors can use this
Diamond works with a network of Texas investors who buy off-market properties at discounts to ARV, using the 75–80% formula with a clear repair estimate. If you are looking for deals and want to see how we structure them, start with how buying from Diamond works, then review the investor marketplace. When builder inventory is high and rates are elevated, the spread between the retail ceiling and a motivated seller’s price is where the opportunity sits, as long as you underwrite the exit honestly.
The bottom line
The data points to a new-home market that is selling slowly in DFW, with 8,938 active listings, 129 days on market, and an average price slipping from $469,398 to $465,663 in a month. It is not a collapse, and it is not a forecast. It is a reason to tighten three habits: derive ARV only from closed resale comps, stress-test the exit down, and price every extra month of carry. Do that, and a slow builder market becomes something you can buy around, rather than something that surprises your exit.
