The pitch is hard to argue with. Brand new house, nobody has ever lived in it, everything under warranty — and an interest rate a full point or two below what you were quoted on a resale. For a first-time buyer staring at today’s payments, that builder rate looks like the only door that is actually open.
I am not here to tell you never to buy new construction. I sell new construction. But I want you to understand what you are trading for that rate, because in the Dallas–Fort Worth metroplex specifically the trade has a geography problem — and it tends to show up two or three years in, right when you want to move.
This is not a conspiracy, it is just math. Builders need large, contiguous, affordable tracts of land. Inside the loop and in the established suburbs that land is either gone or priced out of reach for an entry-level product. So the affordable inventory gets built where the dirt is cheap — and in DFW that means pushing out past the established ring, onto what used to be pasture, often a good forty-five minutes from where you actually work and spend your weekends.
That distance is the real price of the house. It just does not show up on the closing disclosure.
When a builder advertises a rate well below market, that money is coming from somewhere. Usually it is a buydown funded by the builder, and funded out of a sale price that has not been discounted the way it otherwise would have been.
There is a rule here worth knowing, because almost nobody explains it to buyers. Under Fannie Mae’s selling guide the builder is an “interested party” exactly like a private seller is. Fannie lists interested parties as “the property seller, the builder or developer, the real estate agent or broker, any affiliate of the above, or any party that can benefit from the sale of the property at the highest price.” What an interested party may contribute toward your costs on a principal residence is capped by your loan-to-value:
| Your LTV / CLTV | Max seller or builder contribution |
|---|---|
| Over 90% | 3% of the price |
| 75.01% to 90% | 6% |
| 75% or less | 9% |
I want to be straight with you, because the version of this you usually read online is too simple. The contribution cap applies to a builder the same as it applies to a homeowner. But a builder with its own in-house mortgage company has two tools a private seller does not have.
The first is written into Fannie’s own rule. “A lender credit derived from premium pricing, even if the lender is an interested party to the transaction,” is expressly not counted as an interested party contribution — so it sits outside the caps in that table entirely. The second is scale: a captive lender can lock a block of money in advance and parcel it out across a subdivision. Your neighbor selling one house cannot do either.
So a builder’s package can genuinely reach further than a private seller’s. The question is never whether the rate is real. It is what you paid for it.
If the offer is a 2-1 or 3-2-1 buydown, your rate is not low for thirty years — it steps back up. Fannie Mae allows a temporary buydown of at most three percentage points, lasting at most three years, rising no more than one point a year. And there is a detail worth reading twice:
“the lender must qualify the borrower based on the note rate without consideration of the bought-down rate.”
You are underwritten at the real rate. A temporary buydown does not help you qualify for more house — it only softens the first year or two of payments. If your plan depends on your income rising to meet the step-up, that is a plan, not a certainty.
So compare honestly. Ask what the price would be if you brought your own lender and took no incentive. If that number is meaningfully lower, you are not getting a free rate. You are financing it. I walk through the whole mechanism in how builders buy down your rate.
In my experience you cannot negotiate with a builder the way you can with a homeowner. The builder is protecting a price sheet for an entire subdivision.
Here is the part that catches people. Most of these communities are built in phases over several years. When you go to sell in year two or three, the builder is very likely still actively selling in your neighborhood — brand new homes, updated floor plans, and incentive packages you personally cannot match. A buyer walking your street can get new for roughly what you need to get for used.
That is the part I have watched happen. The second half is harder to prove and I want to be careful how I put it: my own sense is that the pool of buyers willing to live that far out is smaller than the pool that was willing to buy new out there with an incentive attached. Treat that as a working agent’s read on the market rather than a measured fact.
Investor ownership gets talked about loosely, so here is what the real research says and what it does not say. An Urban Institute study published in April 2023, using property records as of June 2022, found that “mega” operators — 32 companies that each own at least 1,000 homes — hold 45 percent of their combined single-family portfolios in just six metros, and the Dallas–Fort Worth metro is one of the six, alongside Atlanta, Phoenix, Charlotte, Houston and Tampa.
Read that carefully, because it is routinely mangled. The 45 percent is the six metros together, not DFW’s share. It counts only the very largest institutions, not ordinary small landlords. It is metro-level, so it tells you nothing about any particular subdivision. And the data is several years old now.
Purpose-built rental construction has actually been falling. NAHB’s reading of Census data put single-family built-for-rent starts at about 62,000 in the four quarters ending in the first quarter of 2026 — down 26 percent from 84,000 the year before — and NAHB reported a further decline in the second quarter of 2026. NAHB also notes its count excludes homes a builder sells to an investor after the fact, which it estimates could add another three to five percent of single-family starts.
So do not let anyone, including me, tell you what the investor picture is in your community from national numbers. Find out directly:
Ask the HOA management company, in writing, what percentage of the community is non-owner-occupied, and what the governing documents say about leasing. Some communities cap rentals and some do not, and the answer is in the resale certificate and the recorded declaration — documents you are entitled to read before you are committed.
Many of these developments sit inside a special district that pays for the infrastructure the builder had to install. The Texas Comptroller counts “thousands” of these special purpose districts statewide, “supported by a property tax, sales tax or user fees,” and able to issue debt. Two kinds show up constantly on the edge of DFW:
| Type | What it is | How you pay |
|---|---|---|
| MUD Municipal Utility District |
A water district. TCEQ describes these districts as providing “water, wastewater (sewage), drainage, and other services.” | A property tax rate on top of city, county, school and hospital rates. Districts can levy a maintenance tax and issue bonds, both with voter approval. |
| PID Public Improvement District |
An assessment district created under Chapter 372 of the Texas Local Government Code to fund public improvements in a defined area. | An assessment against your specific lot, commonly payable in annual installments and often prepayable in full. |
Two homes at the same price in two different subdivisions can carry very different monthly payments because of this. Always ask for the actual combined tax rate for that specific subdivision, not the county average, and ask whether a PID assessment can be paid off and what it would cost to do it.
You can check the district yourself before you ever call the builder. Texas special purpose districts report their tax rates and debt to the Comptroller’s Special Purpose District Public Information Database. The Comptroller says plainly that the data is self-reported and has not been independently verified, so treat it as a starting point and confirm the number with the county tax office.
Two years in, the commute is no longer an abstraction. A forty-five minute drive each way is an hour and a half a day you are not getting back, on top of gas and wear. Dinner with friends becomes a project. The gym, the good grocery store, your kid’s activities, your church, your parents — all of it is a drive.
I will put this as what it is, which is my experience rather than a statistic: people do not usually regret the house, they regret the distance.
This is the piece most first-time buyers do not know. A rate buydown is not something only builders can do — a private seller can fund one too, under the same contribution limits. On a resale home, especially one that has been sitting a few weeks, I can negotiate seller-paid points or a 2-1 buydown that gets your payment into similar territory.
The difference is what you own afterward.
That last bullet is real, and it comes with a catch that kills a lot of these deals before they start. VA loans are assumable, but the VA’s own buyer’s guide is blunt about the cost to the seller:
“Anyone, even a non-Veteran, can assume your loan, but in such case your entitlement remains with the loan.”
In plain English: if you are not a veteran and you assume a veteran’s loan, that veteran’s entitlement stays tied up in your house, which can stop them buying their next home with a VA loan. There is one clean way out and it is worth knowing — the VA says a veteran who assumes “can substitute their own VA home loan entitlement to assume your loan, thereby allowing VA to restore your entitlement.” If the buyer is not a veteran, that door is closed. The VA also warns that if an assumed loan later defaults, “it will count against the original veteran’s entitlement.” Plenty of veteran sellers decline once they understand all this, and the assumption needs servicer approval and sometimes VA approval on top.
FHA is simpler in principle. All FHA-insured mortgages are assumable, and for anything closed on or after December 15, 1989 the buyer has to be credit-qualified by the lender. It is a real path, just a slower one than a normal purchase.
Buy the new build if the location genuinely works for your life. Plenty of people are happy out there and they went in with their eyes open. Just do not let a rate be the reason you commit to a forty-five minute drive and a resale market you will be competing in with the company that built your house.
Before you sign anything in a model home, let me run the comparison for you — the builder’s package against what a seller-paid buydown on a resale closer in would actually cost you month to month. It takes one conversation and it is free.
One practical note while you are still at the tour stage. Model home sales staff work for the builder, not for you. Most builders in this market also ask you to register your agent on your first visit, and if you walk in alone you can lose the right to bring one in later — but the policy varies by builder and by community, so ask before you assume it either way. I wrote about how that works in the builder’s agent does not work for you.
Touring model homes on the edge of the Metroplex? Send me the community and the builder's incentive sheet before you sign anything. I will run their package against what a seller-paid buydown on a resale closer in would actually cost you month to month, and tell you which one wins. It takes one conversation and it is free.
Run the comparison for meChecked August 2026. Loan program rules change — confirm current limits with your lender before you rely on them.
