Rate Buydown in Texas: What Every Dallas Buyer Needs to Know in 2026

What is a seller-paid rate buydown and how does it work for Texas home buyers?

A seller-paid rate buydown is a financing concession where the builder or seller deposits money into escrow at closing to temporarily reduce your mortgage interest rate. In the most common structure — the 2-1 buydown — your rate drops by 2% in year one and 1% in year two, then returns to the full note rate for years three through thirty. In 2026, this is the dominant incentive across DFW's new construction market, showing up in communities from Frisco and McKinney down to Anna and Celina.

If you've toured a new construction community in the Dallas suburbs lately, you've probably heard some version of this pitch: "We'll buy down your rate to 4.5% for the first year." It sounds like free money, and sometimes it is. But the number that actually decides your financial outcome isn't the year-one rate — it's the note rate locked in at closing, and the total cost of the builder's package compared to what you could get from an independent lender.

Here's how to read the offer correctly.

How the math works

The 2-1 buydown reduces your interest rate in a staircase pattern: 2% below the note rate in year one, 1% below in year two, then your full note rate from year three through the life of the loan.

On a $400,000 loan at a 6.5% note rate, the monthly principal and interest payments look like this:

The builder deposits the total savings — roughly $9,100 on a $400,000 loan — into a buydown escrow account at closing. Each month, your servicer draws from that account to cover the difference between your reduced payment and your actual payment, until the escrow is exhausted at the end of year two.

Two things most buyers miss: you qualify at the full 6.5% note rate, not the reduced year-one rate. And if you refinance before the two years are up, any unused buydown funds come back to you as a credit at closing.

The builder lender trap

This is where the offer can quietly go sideways.

Builder incentives — including 2-1 buydowns — are typically tied to using the builder's preferred lender. That's legal and common. But it creates a conflict you need to account for before you sign anything.

If the builder's preferred lender quotes you a note rate of 6.75% while an independent lender would give you 6.5%, the buydown savings in years one and two come at a steep long-term cost.

On that same $400,000 loan:

• Builder lender at 6.75%: $2,594/month from year three forward
• Outside lender at 6.5%: $2,528/month from year three forward
• Monthly difference starting year three: $66/month

Over 28 years (year three through year thirty), that's $22,176 more paid to the builder's lender. The two-year buydown savings of roughly $9,100 don't offset that.

The right move is to get a competing quote from a lender outside the builder's network before you sign the contract. The Texas Real Estate Commission (TREC) does not require you to use a seller's or builder's preferred lender — you always have the right to shop.

Most DFW builders will honor the buydown or an equivalent closing credit even if you bring your own lender. It takes one conversation and sometimes a bit of negotiation, but the long-term math is worth asking about.

Rate buydown vs. price reduction: which one actually wins?

This is the real decision for buyers standing in a model home in Frisco or Celina, looking at a builder's incentive sheet.

A price reduction lowers your principal permanently. That means a lower loan amount, a lower monthly payment for the life of the loan, and a lower tax basis for the year you close (though the Collin County Appraisal District and Dallas Central Appraisal District will assess your property independently in subsequent years).

A 2-1 buydown is better when:

• You expect to refinance within three to five years as rates fall — any unused escrow comes back to you
• You have near-term cash flow pressure and need lower payments now
• The builder's note rate is competitive with what an outside lender would offer

A price reduction is better when:

• You plan to hold the home long-term without refinancing
• The builder is quoting a note rate 0.25% or more above the market
• You're financing close to your maximum debt-to-income ratio — a lower loan amount gives you more room

The quick test: compare the total buydown escrow to what the same amount would do as a price reduction. A builder putting $9,100 into a buydown is roughly equivalent to a $9,100 price reduction — but the price reduction saves you money permanently, while the buydown savings disappear after month 24.

If the note rate is market-competitive, the buydown typically wins for buyers who plan to refinance. If the note rate is inflated, the price reduction almost always wins.

Which loan types allow a 2-1 buydown?

Most do. Temporary seller-funded buydowns are available on:

• Conventional loans — Fannie Mae and Freddie Mac both permit seller-funded temporary buydowns; seller concession limits apply (typically 3% with less than 10% down, 6% with 10-25% down)
• FHA loans — permitted per HUD guidelines, but the buydown must be funded by the seller or builder, not the borrower; seller concession cap is 6%
• VA loans — permitted; total seller concessions are capped at 4% of the purchase price
• Jumbo loans — available at most DFW lenders, though terms and concession limits vary by institution

You do not qualify at the reduced year-one rate. The lender uses your note rate in underwriting regardless of what the buydown brings your first-year payment to. If that's a concern for your debt-to-income ratio, getting pre-approved before you tour builder models is the right order of operations.

It's also worth comparing a temporary 2-1 buydown against paying permanent discount points — a different mechanism that locks a lower rate for the full loan term rather than just years one and two. For buyers who are confident they won't refinance for at least seven years, permanent points sometimes pencil out better.

And if you're weighing whether an adjustable-rate mortgage might make more sense than either buydown structure, the DFW ARM vs. fixed comparison covers the current spread and which buyer profile each fits.

Frequently Asked Questions

What happens to the buydown escrow funds if I refinance early?

Any money remaining in the buydown escrow account when you refinance is returned to you as a credit at closing — not to the builder or seller. This makes the 2-1 buydown particularly attractive when mortgage rates are expected to fall. If you refinance at month 18, you receive two years of reduced payments plus a refund of roughly six months of remaining escrow, which can meaningfully reduce your refinancing break-even timeline.

Can I negotiate a seller-paid buydown on a resale home in Dallas, not just new construction?

Yes. A 2-1 buydown is a form of seller concession and can be included in any Texas purchase contract, new construction or resale. In DFW's 2026 resale market, where more than 45% of active listings have taken at least one price reduction, asking for a seller-paid buydown instead of (or alongside) a price cut is a legitimate negotiating strategy. Your agent would draft it into the TREC contract as a seller concession in the appropriate paragraph.

Does a seller-paid rate buydown affect my Texas homestead exemption?

No. The buydown is a financing arrangement and has no effect on your property's appraised value or your homestead exemption eligibility. Your property tax is based on the value set annually by your county appraisal district — not your purchase price, note rate, or how your lender structured the closing.

Is a 2-1 buydown the same as an adjustable-rate mortgage?

No — and this is a common confusion worth clearing up. A 2-1 buydown uses a fixed-rate mortgage. Your note rate is locked for the entire loan term. The buydown uses an escrow account to subsidize your payments in years one and two, but from year three forward your rate never changes. An ARM has a rate that adjusts periodically based on a market index after an initial fixed period — a fundamentally different risk profile.

Which real estate agent should I use when buying new construction in DFW?

Builder contracts are not TREC promulgated forms. They're written by the builder's legal team and don't automatically include the buyer protections you'd find in a standard Texas resale contract — including the option period, appraisal contingency language, and certain earnest money refund rights. The agent who matters most is one who has walked buyers through multiple DFW builder contracts, knows where the risk is buried, and can negotiate with the on-site sales rep from a position of knowledge rather than hope. Paul Blair at Grey Square has represented buyers across Collin County's new construction corridor — Frisco, McKinney, Celina, and Anna — and can give you an honest read on a builder's incentive package before you sign.
