2-1 and 3-2-1 rate buydowns on new construction in Las Vegas (2026)

A rate buydown on new construction in Las Vegas is a way to lower your mortgage payment for the first year or two of the loan — usually paid for by the builder as an incentive — without changing the actual interest rate on your note. The two most common versions are the 2-1 buydown (payment based on a rate 2 points lower in year one, 1 point lower in year two) and the 3-2-1 buydown (3, then 2, then 1 point lower over three years). Here's the part builders' marketing rarely leads with, and the one that matters most: on a conventional loan you qualify at the full note rate, not the reduced rate. This guide walks the actual mechanics — how a temporary buydown affects your debt-to-income qualification, who funds the buydown escrow, how a temporary buydown differs from a permanent buydown (discount points), and how to read builder incentives without getting steered. Every figure below is an illustrative example — not a quote, offer, commitment to lend, or tax advice.

What is a rate buydown on a new-construction home?

A rate buydown is a financing arrangement that temporarily reduces your monthly mortgage payment by covering part of your interest for the first year or two of the loan. As the Consumer Financial Protection Bureau puts it, "with a temporary buydown, the mortgage payment is lowered for the first year or two in exchange for an up-front fee or a higher interest rate later." That up-front money sits in a buydown escrow account and is drawn down each month to make up the difference between your reduced payment and the full payment.

On new construction in Las Vegas — the newer neighborhoods across the valley, from Summerlin and Skye Canyon in the northwest to Cadence and the growing Henderson and North Las Vegas developments — builders frequently offer to fund the buydown as a purchase incentive rather than cut the sticker price. It's a payment cushion for your first year or two in the home, at a time when you may also be furnishing it and settling in. The key thing to hold onto is that a buydown changes your payment, not the note rate written on your loan. When the buydown period ends, you pay the full note-rate payment for the rest of the loan. This matters most on conventional loans within Nevada's 2026 conforming limit of $832,750 for a single unit — buydowns on jumbo new-construction loans follow similar mechanics but may carry different investor-specific rules.

How do 2-1 and 3-2-1 buydowns work in 2026?

Both a 2-1 and a 3-2-1 are temporary buydowns: they discount your payment by a set number of percentage points below the note rate, then step the payment up each year until you reach the full payment. The number in the name tells you the schedule.

• 2-1 buydown. Your payment is calculated as if your rate were 2 points lower in year one and 1 point lower in year two. In year three, you pay the full note-rate payment for good. It's the most common structure builders offer.
• 3-2-1 buydown. Your payment reflects a rate 3 points lower in year one, 2 points lower in year two, and 1 point lower in year three, reaching the full note-rate payment in year four. A deeper cushion — and a larger upfront cost to fund.

So if your note rate were a hypothetical 6.500%, a 2-1 buydown would base your year-one payment on 4.500% and your year-two payment on 5.500%, then settle at 6.500%. A 3-2-1 on the same note would start at 3.500%, then 4.500%, then 5.500%, before landing at 6.500% in year four. (Those rates are illustrative only — not a quote or an offer.) You can see the exact payment steps in the interactive illustration below. The escrow account holds enough money at closing to cover every one of those monthly differences, so from the servicer's point of view the full payment is always made — part by you, part by the escrow.

This step-up cadence is why the buydown suits certain buyers well and others poorly. If you expect your income to rise, or you're moving from a high-cost market and want breathing room your first year or two, a stepped payment can fit. If your budget is already tight at the reduced payment, the year-three (or year-four) reset is a real risk — and it's exactly why the qualification rule in the next section exists.

Do you qualify at the buydown rate or the note rate?

You qualify at the note rate — the full rate — not the temporarily reduced rate. This is the single most important mechanic on this page, and it's federal conventional guideline, not a lender preference. Fannie Mae's Selling Guide B2-1.4-04 states plainly that when underwriting a loan with a temporary interest rate buydown, "the lender must qualify the borrower based on the note rate without consideration of the bought-down rate."

In practice, that means your debt-to-income ratio is measured against the full year-three payment, even though you'll pay less in years one and two. A buydown does not help you qualify for a larger loan or squeeze into a house you couldn't otherwise afford — underwriting already assumes you're making the full payment. Its value is purely cash-flow relief in the early years, not expanded buying power.

Why does this matter so much for a Las Vegas new-build buyer? Because the way an incentive is pitched can blur it. A first-year payment based on a rate 2 or 3 points lower looks dramatically lower than the real one. The disciplined move is to build your budget around the note-rate payment from day one, treat the buydown years as a bonus, and confirm your DTI works at the full number. Our guide to what actually goes into a Las Vegas mortgage payment (PITI) shows how principal, interest, taxes, and insurance stack into that full figure, and how much house you can afford in Las Vegas works the DTI math the way an underwriter will.

Who funds the buydown escrow: builder concession or borrower-paid?

On new construction, the builder most often funds the buydown as a sales concession, depositing the money into a buydown escrow account at closing. The seller, the lender, or you can also fund it — but builder-funded is by far the most common source on a new build. Here are the possible sources:

• The builder (most common on new construction). Builders fund the buydown as a sales concession — an incentive to move inventory without publicly cutting the base price. This is an interested party contribution, and it's subject to conventional limits (below).
• The seller (on a resale). Same idea as a builder concession, negotiated into the purchase contract.
• The lender. A lender can fund a buydown, typically in exchange for a slightly higher note rate — another interested-party arrangement to weigh on total cost.
• You, the borrower. Less common for a temporary buydown, since paying to lower your own payment for only a year or two rarely pencils out versus permanent points.

When an interested party — a builder, seller, or agent — funds the buydown, Fannie Mae's interested party contribution (IPC) caps apply. On a primary residence or second home, the maximum financing concession is up to 3% of the property value with less than 10% down, up to 6% with 10% to 25% down, and up to 9% with 25% or more down; investment properties are capped at 2%. Fannie Mae does not set a separate dollar cap on the buydown itself, but "the total dollar amount of an interest rate buydown must be consistent with the terms of the buydown period," and any concession above the IPC limit is treated as a sales concession that reduces the value used for your loan-to-value calculation. So a builder can fund a serious buydown — but the total help you receive still lives inside those percentage caps.

One servicing detail worth knowing, also from B2-1.4-04: if your loan's servicing is transferred to another company, the remaining buydown funds move with it, and you are never relieved of your obligation to make the full mortgage payment if, for any reason, the buydown funds aren't available. The escrow is a convenience, not a guarantee that erases your note.

Temporary buydown vs. permanent buydown: what's the difference?

A temporary buydown (2-1, 3-2-1) lowers only your payment for a set number of years using escrowed money, then expires; a permanent buydown — discount points — lowers the note rate itself for the life of the loan. Confusing the two is a common and expensive mistake. With points, one point equals 1% of the loan amount, paid at closing, and it typically shaves a fraction off the rate that lasts as long as you keep the loan.

Which is better depends on who pays and how long you'll keep the loan. If the builder is funding a temporary buydown, it's found money for your first year or two — take it, and budget for the reset. If you'd be paying, permanent points often win for a buyer who plans to stay put, because the CFPB's own advice is to "compare the costs for loans with and without the temporary reduced rate to determine the best product for their needs over time." And if rates fall later, some buyers plan to refinance out of the note rate entirely — our conventional refinance guide covers when that math works, and our ARM vs. fixed-rate comparison weighs another way buyers manage a higher-rate environment.

How do Las Vegas new-home builder incentives work in 2026?

Las Vegas builders fund most 2026 rate-buydown incentives as a sales concession baked into the contract, often advertised through — and sometimes conditioned on using — the builder's in-house or preferred lender. That's real value, but the entity marketing the home is also arranging your financing, so it pays to get an independent second opinion before you sign.

Many builder incentives are advertised as available only through the builder's in-house or preferred lender. Some builders' in-house preferred lenders structure the deal around the buydown's eye-catching first-year payment, and the incentive dollars may be conditioned on using that lender. There's an inherent tension there: the entity marketing the home is also arranging your financing, and the number that sells the house (the reduced first-year payment) isn't the number you qualify on (the full note-rate payment). None of that makes a preferred lender wrong to use — but it's a reason to get an independent second opinion on the loan itself.

What to do about it, concretely:

• Separate the incentive from the loan. Ask what the incentive is worth in dollars, then ask an outside lender to price the same loan. In many cases a builder will still apply some or all of those dollars if you bring your own lender — the amount can differ, so get it in writing.
• Qualify at the note rate everywhere. That's the rule covered above (B2-1.4-04) — if a payment estimate leans on the first-year number, ask to see the year-three figure.
• Compare total cost, not the teaser. A lower first-year payment can come with a higher note rate or fees. Look at the full loan — note rate, points, lender fees, and the buydown — side by side.
• Know the concession cap. Whatever the builder contributes toward a buydown and closing costs together is bounded by the IPC limits above.

This is the same principle behind choosing any lender: the structure that's most convenient isn't automatically the one that costs you least. Our breakdown of how to compare conventional lenders in Las Vegas and the difference between a credit union and a mortgage broker both apply directly to a builder's preferred-lender pitch.

See the payment step-up (illustrative only)

Use the illustration below to see how a 2-1 or 3-2-1 buydown steps your payment up year by year, and roughly how much money someone would deposit into the buydown escrow to fund it. Enter a loan amount and a hypothetical note rate. Every buydown year is calculated one point at a time down from the note rate — it's a directional teaching tool, not a quote, an approval, or an offer to lend.

On a hypothetical $450,000 loan at a 6.500% note rate, a 2-1 buydown makes your year-one payment about $2,280/mo (based on 4.500%) and year two about $2,555/mo (based on 5.500%), before the full $2,844/mo note-rate payment kicks in from year three — funded by roughly $10,242 in escrow. A 3-2-1 on the same loan starts near $2,021/mo and takes about $20,125 to fund. These are illustrative principal-and-interest figures only — not a quote, offer, or commitment to lend — and your real payment also includes taxes, insurance, and any PMI on a conventional loan.

Is a rate buydown on a new build a good idea?

It can be an excellent deal — when it's builder-funded and you'd qualify comfortably at the full note-rate payment anyway. In that case, the buydown is pure upside: someone else pays to soften your first year or two, and you were going to be fine at the full payment regardless. That's the ideal scenario, and it's common on Las Vegas new construction right now.

Where it goes wrong is when the buydown is doing the heavy lifting to make the home feel affordable. Signs to slow down:

• Your budget only works at the reduced payment. If year three's full payment would strain you, the buydown is postponing a problem, not solving it. Remember, you already had to qualify at that full payment.
• The incentive is locked to a higher note rate. A builder-preferred loan with a buydown but an above-market note rate can cost more over time than a plain loan at a lower rate. Compare total cost.
• You expect to move or refinance within the buydown window. If you'll be gone in two years, a 3-2-1's deeper (and pricier-to-fund) cushion may be wasted — though unused escrow is generally credited back at payoff.

The healthiest way to treat a temporary buydown is as a bridge, not a foundation: helpful for easing into a new home, planning for a known income increase, or buying time to refinance if rates fall — never as the thing that makes an unaffordable payment look affordable. If you're new to the process, our first-time home buyer guide for Las Vegas and the full conventional learning center walk the fundamentals, and relocating buyers often find a builder buydown especially useful — see moving to Las Vegas from California for how that transition maps to financing.

The bottom line

A rate buydown on a Las Vegas new build lowers your payment for the first year or two, usually on the builder's dime, then steps up to the full note-rate payment. The mechanics that actually protect you are simple to remember: you qualify at the note rate, not the reduced rate (Fannie Mae B2-1.4-04); the money is escrowed up front and, when a builder or seller funds it, capped by IPC limits (3/6/9% by down payment); and a temporary 2-1 or 3-2-1 is a different animal from permanent discount points. Treat a builder-funded buydown as a welcome bonus on a loan you can already afford — never as the reason a payment "works."

The most valuable move before you sign a new-construction contract is to have an independent, local lender price the loan two ways and confirm your budget holds at the full payment. That's the difference between an incentive that saves you money and one that just sells you a house.
