Texas Builder Buy-Down 2026: How New Home Builders Are Subsidizing Interest Rates

Texas Builder Buy-Down 2026: How New Home Builders Are Subsidizing Interest Rates

Why Builders Are Paying Your Interest and What It Actually Costs Them (and You)

Walk into a new home sales office anywhere in the Houston metro in 2026 and you will likely see a placard advertising a rate in the 5-point-something percent range. The market rate for a 30-year fixed mortgage sits near 7%. The gap between those two numbers is not magic. It is cash that the builder or its affiliated mortgage company is depositing on your behalf, either into a buydown escrow account or directly to the lender as discount points. Understanding how that money moves, who benefits, and what strings are attached separates buyers who use the incentive intelligently from buyers who pay full price for a manufactured discount.

TL;DR: Texas builders in 2026 are offering temporary buydowns (2-1 and 3-2-1 structures) and permanent rate buydowns as the primary affordability tool in a market where the 30-year fixed rate is near 7%. A 2-1 buydown on a $400,000 loan brings year-one payments down by roughly $450 to $550 per month versus the note rate, but the payment jumps to full cost in year three. Permanent buydowns reduce the rate for the life of the loan, often to the 5.5% to 5.99% range, funded by builder-paid discount points. The catch in both cases: builder pricing is typically 5% to 10% above comparable resale, and many incentive packages require using the builder's captive lender, removing your ability to shop for competing rates. According to American Enterprise Institute analysis, reducing a rate by 100 basis points costs the builder roughly 3.2% of the sale price, while achieving the same payment reduction through a price cut would require a 10% price reduction. Builders choose buydowns because they are cheaper for the builder than cutting the sticker price.

The 2-1 Buydown: Mechanics, Math, and the Third-Year Reality

A 2-1 buydown is a temporary rate reduction funded by a lump sum deposited into an escrow account at closing. The funds come out of that escrow in monthly installments over the first two years to supplement your payment, so your actual interest cost to the lender is always at the full note rate. From your perspective as a borrower:

• Year 1: Your effective rate is 2 percentage points below the note rate. On a 7% note, you pay as if the rate is 5%.
• Year 2: Your effective rate is 1 percentage point below the note rate. On a 7% note, you pay as if the rate is 6%.
• Year 3 and beyond: Your rate returns to the full 7% note rate for the remaining 28 years of the loan.

The buydown escrow is funded upfront, entirely by whoever is paying for it. In new construction, that is typically the builder or its affiliated lender. On a conforming 30-year fixed loan at 7%, the cost to fund a 2-1 buydown on a $400,000 loan is approximately $8,000 to $9,500, representing the total monthly payment difference over 24 months. That cost is part of what the builder calls "seller concessions" or "incentives" in the sales contract.

Real rate example with a $400,000 loan at a 7.00% note rate:

The escrow-funded subsidy totals: (12 x $534) + (12 x $283) = $6,408 + $3,396 = $9,804. That is the actual cash cost to the builder to deliver this benefit.

The critical number every buyer must internalize: month 25, when the full 7% payment kicks in. If your income does not grow, if you have not refinanced, and if market rates have not fallen enough to make a refinance worthwhile, you face a $514 per month payment jump with no warning. The Fannie Mae Selling Guide on Temporary Buydowns requires lenders to qualify borrowers at the full note rate (not the reduced buydown rate) specifically because of this payment shock risk.

The 3-2-1 Buydown: Three Years of Relief, Same Cliff at the End

The 3-2-1 buydown extends the reduced-rate period to three years, with the rate reduction stepping down each year:

• Year 1: Note rate minus 3 percentage points
• Year 2: Note rate minus 2 percentage points
• Year 3: Note rate minus 1 percentage point
• Year 4 and beyond: Full note rate

On a 7% note, year-one borrowers pay as if the rate is 4%. That is a significant monthly payment reduction and a powerful sales tool. DHI Mortgage (D.R. Horton's affiliated lender) has offered 3-2-1 buydown programs in Texas, and the mechanics create what looks like an entry-level rate that is dramatically below market.

The escrow cost of a 3-2-1 buydown is higher than a 2-1 buydown because it covers three years of subsidies. On the same $400,000 loan at 7%:

Total escrow cost: (12 x $751) + (12 x $514) + (12 x $263) = $9,012 + $6,168 + $3,156 = $18,336. The builder is spending nearly $18,500 to make year-one payment look like a $1,910 monthly obligation. That money is not free. It comes from the home's price, the builder's incentive budget, or both.

Note that a DHI Mortgage promotion in late 2025 offered rates as low as 0.99% in year one on select Texas properties, which was a 3-2-1 structure that stepped to 1.99% in year two, 2.99% in year three, and 3.99% for the life of the loan thereafter. That exceptional offer was tied to a permanently bought-down note rate of 3.99%, which required the builder to fund both a permanent buydown and a 3-2-1 escrow layered on top. The complexity illustrates how aggressively builders are willing to structure incentives when inventory is elevated.

Permanent Rate Buy-Downs: Lower Rate for Life of Loan

A permanent buydown works differently from a temporary one. Instead of funding an escrow account that supplements payments for a fixed period, the builder (or buyer) purchases discount points at closing that permanently reduce the interest rate on the loan. Each discount point typically equals 1% of the loan amount and reduces the rate by approximately 0.25%, though the exact reduction varies by lender and market conditions. To reduce a 7% rate by a full 1%, a buyer typically needs 3 to 4 points, or 3% to 4% of the loan amount.

In practice, builders funding permanent buydowns in 2026 use what the American Enterprise Institute calls a "bulk forward commitment": the builder pre-pays a large block of mortgage commitments at a below-market rate, locking in a pool of money for a defined period. Buyers in those communities can access rates that would cost 2 to 4 additional points if obtained on the open market. This is how builders advertise rates of 5.50% to 5.99% in a 7% market and actually deliver them.

What it costs the builder: AEI data shows that approximately 64% of new homes sold by large builders in 2025 used a permanent buydown, with an average rate discount of about 1.3 percentage points at an estimated cost of 5% of the mortgage amount in builder concessions. On a $400,000 loan, that is $20,000 in builder funds deployed to reduce your rate from 7% to 5.7%.

Perry Homes Spring 2026 Savings Event example: Perry Homes' Spring 2026 promotional offer in the San Antonio and Austin markets advertised a 4.99% rate (5.178% APR) through Crestmark Mortgage or Parkstone Mortgage on select inventory homes, with up to $50,000 in total incentives including closing cost contributions, the buydown, and design center allowances. The fine print specifies that using Crestmark or Parkstone is required to receive the promotional rate, illustrating the captive lender structure common across the industry. Perry Homes does not originate mortgages itself; Crestmark (NMLS #287961) and Parkstone (NMLS #2065952) are the actual lenders.

Builder Captive Lenders in Texas 2026: Lennar, Perry, KB, DR Horton

The four largest publicly traded builders in Texas each operate affiliated mortgage companies that are central to their incentive programs. Understanding the captive lender structure is essential before accepting any rate offer.

Lennar Mortgage (LMI): Lennar Mortgage, LLC is the financing arm of Lennar Corporation, one of the largest home builders in the Houston metro with active communities in Balmoral (Humble), Pomona (Manvel), Harvest Green (Richmond), and Sorrento (Conroe), among others. LMI offers FHA, VA, conventional, and jumbo products. In 2026, Lennar Mortgage's incentive packages typically include a closing cost contribution or rate buydown structured to be available only when using LMI. The Lennar Mortgage Advantage Plus program also provides up to 5% down payment assistance as a second lien, available on select FHA first mortgage products. Buyers should request the full Loan Estimate from LMI and compare it to a Loan Estimate from at least one independent lender on the same scenario.

DHI Mortgage (D.R. Horton): DHI Mortgage Company, Ltd. (NMLS #14622) is the captive lender for D.R. Horton, the largest home builder by volume in the U.S. and a major presence in Houston-area communities including Pomona, Sterling Lakes (Rosharon), Sweetwater (Sugar Land), and Harmony (Spring). DHI Mortgage has offered 2-1 and 3-2-1 buydown programs aggressively in 2025 and 2026 as D.R. Horton works through elevated inventory levels. DHI Mortgage's incentive programs are available exclusively to buyers of D.R. Horton homes and require using DHI Mortgage as the lender.

KBHS Home Loans (KB Home): KB Home's affiliated lender, KBHS Home Loans (a joint venture with Nationstar Mortgage, now Mr. Cooper), offers rate lock programs for construction periods and rate buydown options. KBHS Home Loans provides a Builder 90 rate lock for construction-phase loans and offers discount point purchases at closing. KB Home communities in the Houston area include developments in Katy, Cypress, and Conroe. KB Home has also offered closing cost assistance and appliance packages alongside rate incentives in 2026.

Perry Homes (Crestmark/Parkstone): Perry Homes operates through two preferred lenders: Crestmark Mortgage Company, Ltd. (NMLS #287961) and Parkstone Mortgage, LLC (NMLS #2065952), both headquartered in the Houston area. As noted above, Perry's Spring 2026 promotion required the buyer to select and qualify with Crestmark or Parkstone to access the advertised 4.99% rate. Perry Homes is active in Bridgeland (Cypress), Meridiana (Manvel), Candela (Richmond), and Harvest Green (Richmond), among other Houston-area master-planned communities.

Common thread: All four builders require the buyer to use the affiliated or preferred lender to receive the incentive. Buyers who use an outside lender may still purchase the home but forfeit the rate incentive (and sometimes the closing cost contribution). The question is whether the incentive plus the captive lender's pricing beats the rate you could get on the open market.

When the Buy-Down Beats a Price Discount

The buy-down versus price cut comparison is not always obvious. Here is when the buydown is the better deal:

1. DTI-tight qualifying situations. Lenders qualify borrowers for temporary buydowns using the full note rate, not the reduced buydown rate, per Fannie Mae guidelines. However, for permanent buydowns, the qualifying rate is the actual bought-down rate. If a buyer is borderline on the debt-to-income ratio at 7% but clears it at 5.75%, a permanent buydown from the builder can expand their purchasing power in a way that a price reduction does not. A $20,000 price reduction on a $400,000 purchase saves approximately $133 per month at 7%; a $20,000 permanent buydown reduces the rate by roughly 1.5% on a $400,000 loan and saves approximately $386 per month, making a meaningful difference for a buyer whose DTI is 44% and needs to get under 43%.

2. Cash-flow management in the short term. For buyers who expect their income to grow in two to three years (a physician completing residency, a W-2 employee expecting promotion, a dual-income household planning to return to full income after parental leave), a 2-1 buydown provides intentionally lower payments during the period of tighter cash flow. The note rate payment that kicks in at year three is manageable given the anticipated income trajectory.

3. Short-hold buyers who plan to sell or refinance before year three. If you expect to hold the home for two to four years and believe rates will be meaningfully lower by then (enabling a refinance), a 2-1 buydown captures real cash savings during the hold period. The "cliff" at year three is mitigated if the plan is to refinance in year two or three when rates improve.

4. When the escrow is credited back if you sell. Some buydown escrow agreements return any unused escrow balance to the seller (you) if you sell the home before the buydown period ends. In that case, the escrow functions partially as a refundable deposit, reducing the opportunity cost of the buydown structure.

When the Buy-Down Does NOT Make Sense

1. When the builder's price is 5% to 10% above comparable resale. AEI research shows builders price homes to absorb the cost of incentives rather than passing them through as true savings. If the new construction home you are considering is priced at $450,000 and comparable resale homes in the same area are selling at $415,000 to $425,000, the $25,000 to $35,000 price premium exceeds the value of most buydown packages. A permanent buydown funded at $20,000 still leaves you $5,000 to $15,000 behind a resale buyer at full market rate. Run the comparison: total cost of the new home (price plus any upfront costs minus the buydown benefit value) versus total cost of a comparable resale with an independently sourced mortgage.

2. When lender captivity removes shopping power. If you must use DHI Mortgage or Lennar Mortgage to receive the incentive, you cannot compare competing loan products, lenders, or rate sheets. The captive lender may be pricing the loan at origination fees or LLPAs that a competitive lender would not charge. Regulatory concerns raised in 2026 highlight that builder-affiliated lenders have reported some of the highest percentages of underwater FHA mortgages, suggesting underwriting standards may differ from independent lenders.

3. When you plan to hold the home long-term and rates stay elevated. A 2-1 or 3-2-1 buydown on a 7% note rate leaves you at 7% starting in year three (or year four for a 3-2-1). If rates do not fall and you do not refinance, you are carrying the full note rate for 27 or 26 of the 30 years. In that scenario, a price reduction of equal dollar value would have permanently lowered your loan balance and your interest cost for the entire term.

4. When the incentive is structured as a closing cost credit, not a buydown. Some builders offer what they describe as "up to $25,000 in incentives" that the buyer can apply to closing costs or rate buydowns. If the closing cost credit is used to fund things you would have paid for anyway (title policy, origination fee, prepaid taxes and insurance), the credit is valuable but unrelated to the buydown math. Do not conflate the two.

Worked Example: $420,000 New Home in a Houston Master-Planned Community

Consider a buyer evaluating a new D.R. Horton home in a Spring 77379 community at $420,000 (5% down, $399,000 loan after minimum down payment) with a DHI Mortgage 2-1 buydown incentive advertised at a 5.00% first-year rate. The note rate from DHI Mortgage is 7.00%.

Buydown Option (using DHI Mortgage at 7.00% note, 2-1 buydown):

• Year 1 effective rate: 5.00% | Monthly P&I: $2,142
• Year 2 effective rate: 6.00% | Monthly P&I: $2,393
• Year 3 and beyond: 7.00% | Monthly P&I: $2,655
• Two-year escrow cost funded by builder: approximately $9,750

Alternative: Resale Home at $390,000 (comparable square footage, same ZIP code, 5% down, $370,500 loan at 7.00% open market):

• Monthly P&I at 7.00%: $2,466
• No buydown benefit

Year 1 comparison: DHI Mortgage option saves $2,142 vs $2,466 = $324 per month savings. But the buyer paid $30,000 more for the home ($420K vs $390K). At $324/month savings, it takes 92 months (7.7 years) for the payment savings to break even against the $30,000 price premium, ignoring time value of money. If the buyer refinances or sells before year eight, the new construction home cost more.

Year 3 comparison (when buydown expires): The DHI Mortgage buyer now pays $2,655 per month. The resale buyer at the same rate still pays $2,466. The new construction buyer is now paying $189 per month more, compounding the price premium disadvantage.

The worked example shows that the buydown only wins if: (a) the price premium is small or nonexistent, (b) the buyer holds long enough for the payment-savings break-even to arrive, or (c) rates fall and the buyer refinances the 7% note before year three.

For buyers in communities where builder pricing is close to resale (some master-planned communities with controlled resale inventory), the buydown can be a genuine benefit. See our analysis of best Houston master-planned communities for ROI for community-by-community pricing comparisons.

How to Negotiate Cash Incentive or Upgrade Allowance Instead

Buyers who prefer a lower purchase price or an upgrade allowance over a rate buydown have legitimate negotiating room, particularly on spec homes (completed, unsold inventory) where the builder has carrying costs accumulating every month.

Strategy 1: Ask for the cash equivalent of the buydown as a closing cost credit. If the builder's incentive package is worth $20,000, ask for $20,000 in closing costs paid by the seller on the Closing Disclosure. Apply those funds to reduce your loan balance or pre-pay escrow items rather than funding a buydown. This lowers your loan balance permanently.

Strategy 2: Request an upgrade allowance in lieu of the rate incentive. Builders typically have higher margins on design center upgrades (flooring, cabinetry, counters) than on rate subsidies, because the wholesale cost of upgrades is much lower than the cash cost of buying down a mortgage rate. A $15,000 design center allowance may cost the builder $6,000 in actual materials and labor, while a $15,000 rate buydown costs the builder $15,000 in real cash. Knowing this, buyers can often negotiate more upgrade value than equivalent cash value if they frame the request around design center options.

Strategy 3: Use your own lender and negotiate price. If you have an independently obtained pre-approval (see our Texas Pre-Approval vs Pre-Qualification guide for the distinction), you know your competitive rate without the captive lender. Present a cash-equivalent offer using your own financing and negotiate the price down by the amount the builder would otherwise spend on the buydown. Builders prefer to move inventory and may accept this structure, especially on spec homes sitting for 60 or more days.

Strategy 4: On a 2-1 buydown, negotiate the unused escrow to be returned to you at sale. Many buydown escrow agreements default the unused balance to the lender if you sell or pay off the loan early. Request language specifying that unused escrow funds are credited to you at sale. This converts a use-it-or-lose-it incentive into a partial refund if you sell before the buydown period ends.

When evaluating any builder incentive package alongside Texas closing costs and your overall financing structure, the starting point is knowing your real market rate independently. Understanding whether an FHA, conventional, or VA loan is best for your situation first (see our FHA vs Conventional vs VA guide) prevents the builder's captive lender from steering you into the wrong loan type to make their incentive package work.

Understanding the Mortgage Rate Lock for New Construction

New construction purchases present a specific rate lock challenge that does not exist in resale: completion dates are uncertain, and a 7% rate locked today may need to be held for six to nine months if the builder pushes the timeline. Understanding Texas mortgage rate lock options before committing to a new construction contract is essential, because a builder's affiliated lender may offer a "builder rate lock" that ties your rate to their specific pool of commitments and cannot be transferred if you switch lenders mid-construction.

The builder rate lock at the captive lender solves the new construction timing problem but reinforces the captive lender relationship. Ask explicitly: what happens to my rate if construction is delayed 90 days? What is the rate lock extension policy? Does the builder absorb the extension cost, or does the buyer?

Frequently Asked Questions

What is the escrow account in a 2-1 buydown and who controls it?

The buydown escrow is a third-party account funded at closing, typically held by the mortgage servicer. The funds in the account represent the total payment difference between the reduced buydown rate and the full note rate over the buydown period. Each month, the servicer withdraws the subsidy amount from the escrow and applies it to your mortgage payment, so the lender always receives the full note rate payment. You as the borrower pay only the reduced amount. You do not control the account or have access to the funds; they are disbursed automatically. If you sell the home or pay off the loan before the buydown period ends, the remaining escrow balance disposition (credited to you, to the lender, or to the buyer) depends on the specific agreement. Negotiate this term before closing.

Does using the builder's captive lender hurt my ability to compare loan products?

Yes, meaningfully. When you commit to using the captive lender to receive the builder's incentive, you give up the ability to shop Fannie Mae and Freddie Mac rate sheets across multiple lenders, which is where most competitive pricing is discovered. Captive lenders operate within the same rate environment as independent lenders, but their incentive to be price-competitive is lower since you are locked in. Before signing a purchase contract requiring a specific lender, request a Loan Estimate from the builder's lender and compare it to Loan Estimates from at least two independent lenders on the identical scenario (same loan amount, same loan type, same lock period). If the captive lender's pricing is within 0.25% of the open market, the builder's incentive may still be worthwhile. If the captive lender's rate is 0.50% or more above market on an equivalent product, the incentive may not fully offset the pricing disadvantage.

How does Fannie Mae treat builder-funded temporary buydowns when calculating DTI?

Fannie Mae's Selling Guide requires lenders to qualify borrowers at the full note rate on loans with temporary buydowns, not at the reduced buydown rate. This means a buyer taking a 2-1 buydown with a 7% note rate is qualified at 7%, even though their year-one payment is at 5%. The buydown does not help with DTI qualification for temporary structures. Permanent buydowns are different: since the bought-down rate is the actual contractual rate for the full loan term, lenders qualify borrowers at the permanently reduced rate, which can meaningfully expand purchasing power for DTI-constrained buyers.

Are builder buy-downs available on VA and FHA loans, not just conventional?

Yes, with restrictions. The VA Home Loans program allows temporary buydowns on all fixed-rate VA loans, including purchase loans, with the buydown funded by the seller, builder, or lender. Builder-paid buydowns are treated as seller concessions, capped at 4% of the reasonable value of the home. VA lenders must still qualify borrowers at the full note rate. FHA loans also permit seller-funded temporary buydowns, subject to FHA's maximum seller contribution limits. One important distinction: FHA's maximum seller contribution is 6% of the purchase price, which a large incentive package can easily reach, potentially making the full buydown ineligible if other seller contributions (closing costs, prepaids) are also being covered.

If rates drop to 5.5% by year three, does it make sense to refinance out of the buydown?

If the market rate at the time falls to 5.5% and your note rate is 7%, refinancing into a 5.5% loan would reduce your payment and eliminate the year-three payment shock. However, refinancing carries its own closing costs, typically 2% to 3% of the loan amount, or $8,000 to $12,000 on a $400,000 balance. The refinance makes mathematical sense if you plan to hold the home long enough for the monthly savings to exceed the refinance cost (the break-even horizon). On a $400,000 loan, refinancing from 7% to 5.5% saves approximately $390 per month; at $10,000 in closing costs, break-even is approximately 25 months. Factor this into your holding period plan before committing to either the buydown or the refinance strategy.

Can I negotiate the builder down on price instead of taking the rate incentive?

Yes, and this is often the better strategy on spec homes (completed homes sitting unsold). Builders have carrying costs on completed inventory (interest on construction loans, insurance, HOA fees) that accumulate every month the home is unsold. On a home that has been sitting for 60 or more days, negotiating a $15,000 to $25,000 price reduction is often feasible, particularly if you come with a strong pre-approval and a quick closing timeline. A price reduction permanently lowers your loan balance and your lifetime interest cost, unlike a temporary buydown that expires after 24 months. The builder's sales team will typically present the rate incentive first because it is cheaper for the builder than a price cut; push back with a counter that includes a price reduction and watch how the negotiation develops.
