A 2 to 1 buydown is one of the most talked about tools in Texas new construction right now, and one of the most misunderstood. Buyers hear “lower rate” and stop asking questions. On a Texas new build, where the builder may be the one offering it, the questions are the whole point. The buydown is also only one line in the real cost picture, and we walk through the rest in the new construction costs North Dallas buyers do not expect.
Here is how it actually works, who pays for it, and when you should take the buydown versus asking for something else.
What a 2 to 1 Buydown Actually Is
A 2 to 1 buydown is a temporary reduction of your interest rate for the first two years of the loan. It works in percentage point steps off your locked note rate.
In year one, your rate is 2 percentage points below your note rate. In year two, it is 1 percentage point below your note rate. In year three, it steps up to the full note rate, and it stays there for the rest of the loan unless you refinance.
Two things buyers miss. First, the money that funds those first two years of savings is deposited at closing into a buydown account and applied to your payment each month. It is real money, paid up front, usually by the seller or the builder. Second, you are generally qualified at the full note rate, not the buydown rate, so the buydown does not help you qualify for more house. Confirm the qualifying rules for your loan program before you write an offer.
Who Pays for It on a Texas New Build
On a Texas new build, the buydown is almost always funded by the builder as a seller concession, which the loan guides call an interested party contribution. Builders offer buydowns because a buydown keeps the sales price intact while still lowering what you pay in the early years. A price cut lowers their recorded sales price and every future comp in the community. A buydown does not.
How much a builder can contribute is capped by your loan program, not by the builder. The current caps: FHA allows up to 6% of the sales price in interested party contributions, and that 6% explicitly includes temporary and permanent buydowns (HUD Handbook 4000.1). VA allows the seller to cover customary closing costs without limit, plus up to 4% in true concessions, which include buydowns. Conventional loans scale with your loan to value: 3% above 90%, 6% between 75.01% and 90%, and 9% at 75% or below (Fannie Mae Selling Guide, May 2025).
So when a builder offers you a buydown, the right question is not just “how much.” It is “how much room do I have under my program’s cap, and what else am I giving up to get this?”
Buydown vs Price Reduction vs Closing Cost Credit
These are the three levers a builder can pull, and they do different things.
A buydown lowers what you pay in years one and two. It helps most when your budget is tightest early, which is exactly where relocating buyers usually are. You are adjusting to Texas property taxes, new bills, and a new cost of living all at once. If the tax side is new to you, start with how Texas property taxes, MUD and PID fees actually stack up.
A price reduction lowers the amount you finance for the entire life of the loan. It also lowers your property tax base and can help the appraisal. But builders protect their prices, so deep price cuts are rare on new builds.
A closing cost credit reduces the cash you need at the closing table. It helps if your challenge is cash to close rather than the early years of payments.
There is no universal winner. A buyer who is cash tight at closing but comfortable with the long term payment may do better with a credit. A buyer whose first two years are the squeeze may do better with the buydown. A buyer planning to stay a decade may do better pushing for price. Run your own numbers before you choose, on a call, not in the model home.
When a Buydown Makes Sense and When It Does Not
A buydown makes sense when your income or budget is expected to grow into the full payment, when you may refinance if rates fall, or when the builder will fund it but will not move on price. On a Texas new build, that last one is common. The buydown is often the concession the builder is most willing to give.
A buydown is the wrong move when you plan to stay in the home long term and the seller’s concession could have bought you a permanent rate reduction instead. Discount points lower your note rate for the life of the loan. A temporary buydown only lowers it for two years. If you are not going anywhere and the math favors permanent, take permanent.
It is also the wrong move if the buydown eats your entire concession budget and leaves nothing for the closing costs you actually need covered. The buydown is one line item inside your program’s cap. Treat it that way.
What If Rates Drop? Do You Lose the Buydown?
This is the question I get most, and the answer is the reason a temporary buydown is a reasonable hedge. The buydown money was deposited at closing. If you refinance or sell while the buydown is still active, the unused portion is generally credited to reduce your loan balance. You do not lose it. The exact handling follows your buydown agreement, so read it, but the structure is designed so an early refinance does not waste the concession.
Questions to Ask Before You Accept a Builder Buydown
Ask these before you sign, in this order.
- Who is funding the buydown, and is it inside my loan program’s concession cap?
- Am I being qualified at the full note rate or the buydown rate?
- What happens to the unused buydown funds if I refinance or sell in the first two years?
- What would this same concession buy me as a permanent rate reduction or a closing cost credit instead?
- Is the builder’s preferred lender required, and have I compared that offer against an outside lender in writing?
That last question matters. Builder incentives are real, but so is your right to shop your loan. Get the outside numbers in writing before you decide. Representation matters just as much: read why you need your own agent for a Texas new build before your first model home visit.
