The rate quoted on a lender's sheet isn't the payment you have to live with — a temporary mortgage buydown can cut your first-year payment by hundreds of dollars a month even when the 30-year fixed rate sits above 7%. The daily average for 30-year fixed rates hit 7.60% in early October 2026 (HomeServices Lending), yet buyers who only compare sticker rates are missing the lever that makes ownership affordable again.
A buydown works by pre-paying interest so your payment runs below the note rate for the first year or two. In a 1-0 structure you pay 1% less in year one, then step up to the full rate in year two. A 2-1 buydown cuts the rate 2 points in year one and 1 point in year two, then jumps to the note rate in year three. The difference matters most now, because high rates — not high prices — are what's freezing buyers out of the market.
What exactly is a 1-0 buydown?
A 1-0 buydown is a temporary subsidy that lowers your effective interest rate by 1 percentage point for the first 12 months of the loan, then steps up to the full note rate from year two onward. The money that covers the gap between your reduced payment and the full payment is set aside in escrow at closing and drawn down as your payments come due.
The buyer pays less each month in year one, and the servicer fills the difference from that escrow account. A Rocket Mortgage example on a $300,000 loan at a 7% note rate shows a 1-0 structure saving $197 a month, or $2,367 across the first year — then the payment jumps to the full rate for the remaining 29 years.
The 1-0 is the lighter touch of the two structures. It's a one-year bridge, which suits buyers who expect to refinance soon, expect their income to grow, or simply need to survive the first 12 months of homeownership without stretching their budget to the breaking point.
Who pays for the buydown — and why a seller would?
The two structures in this article are usually paid differently, and that difference shapes the deal. A 1-0 buydown is often what's called a lender-paid buydown: your mortgage lender credits the escrow as part of a promotional pricing offer, so it costs you little or nothing up front. A 2-1 buydown, by contrast, is most often seller-paid — the seller contributes the escrow amount at closing, often instead of cutting the list price.
Why would a seller hand over thousands of dollars rather than just lower the price? Because a buydown concession often does more for the buyer's monthly budget than an equivalent price reduction does. Rocket Mortgage quotes a blunt rule of thumb: "seller-funded buydowns typically provide more value than equivalent price reductions on a home for sale." A builder in particular can advertise a striking year-one rate — one Las Vegas builder pushed a 2-1 buydown on top of a 4.875% permanent rate in fall 2026 (Nevada Real Estate Group) — to draw offers without permanently lowering the asking price.
Sellers and builders aren't being altruistic. In a market where price cuts are surging and buyers are rate-sensitive, a buydown is a powerful negotiating tool: it lets a seller move a home without a headline price cut, and it lets a buyer lock in affordability they couldn't reach through a lower list price alone.
Side-by-side: what each structure saves
To see the real dollar impact, compare both structures on the same loan. U.S. News ran the numbers on a $400,000 loan at a 6.5% note rate: the 1-0 drops the payment to $2,271 a month in year one, and the 2-1 drops it to $2,027 in year one, then $2,271 in year two, before both settle at the full $2,528 payment (U.S. News).
The 1-0 structure's total savings come to about $3,085 across year one, while the 2-1 totals about $9,104 across two years (U.S. News). That's the trade-off in plain numbers: a 1-0 gives you one year of modest relief, while a 2-1 gives you roughly three times the total savings over a longer runway.
Why buydowns matter in a 7% market
The strategic case for buydowns rests on today's rate environment, and the numbers are stark. Mortgage rates hit new highs in late September and early October 2026, with the daily average for 30-year fixed rates surging to 7.60% and the MBA weekly benchmark at 7.30% (HomeServices Lending). Purchase demand has frozen — total mortgage demand dropped 6% in a single week — as buyers balk at the monthly cost.
This isn't a niche trick either. Temporary buydowns saw a resurgence in 2025 as affordability worsened, and a March 2026 survey found 64% of builders were offering sales incentives including rate buydowns and closing-cost credits (U.S. News).
Which one should you choose?
Pick the structure by matching it to your timeline and your budget, not by which one sounds bigger. A 1-0 buydown suits the buyer who plans to refinance within 12 to 18 months or simply needs to soften the first-year cash outlay on a home they expect to keep for years. A 2-1 buydown is the stronger play when you'll live with the full payment by year three but want a longer runway of relief to absorb moving costs, furnishing, and the other first-year expenses of ownership.
Two checks decide it. First, can you afford the step-up? If the jump to the full note-rate payment after year one or year two breaks your budget, a buydown is a short-term fix that becomes a long-term problem — U.S. News warns buyers to be sure they can handle the final payments once the buydown period expires. Second, who's funding it? A seller-paid buydown costs you little up front but is capped by loan-program limits on seller contributions, and a seller must agree to it — concessions are negotiated, never guaranteed (EZ Funding Group).
The bottom line for today's buyers
In a market where the 30-year rate has climbed to 7.60%, a buydown is the difference between renting and owning for many buyers. The key insight is that you don't have to wait for rates to fall to make a purchase work. A 1-0 or 2-1 structure — whether lender-paid or negotiated as a seller concession — buys you the affordability window you need now, and the note rate underneath means you can refinance to a lower payment the moment the market cooperates.
The rate on the lender's sheet is not the final word on what your mortgage costs. Ask your loan officer to run the numbers on both a 1-0 and a 2-1 buydown on the exact home you're considering, and get the seller's concession in writing. In a high-rate market, the smartest strategy is often the one that lowers your monthly payment today.
