Mortgage Rate Buydown — 2-1 Buydown, 3-2-1 Buydown & Permanent Points Explained

A mortgage rate buydown is a subsidy that lowers the borrower's payment for a defined period at the beginning of the loan. There are two different ideas hiding under the same phrase. A temporary buydown lowers the effective payment for one, two, or three early years. A permanent buydown means paying discount points to reduce the note rate for the full life of the loan.

In the 2026 market, the temporary version is what most buyers are actually seeing in builder ads and listing concessions. The common form is the 2-1 buydown: the payment is calculated as though the rate were 2% lower in year one and 1% lower in year two, then the full note rate starts in year three.

This guide focuses mostly on temporary buydowns because they are the main negotiation tool in the market right now. For permanent points, use the mortgage points guide.

Using the planning example from the spec, a $400,000 loan with a permanent note rate of 6.52% has a standard principal-and-interest payment of about $2,534/month. A 2-1 buydown changes the early payment schedule like this:

The total first-two-year subsidy is about $9,113. That number matters because the buydown cost is not magical. Someone funds that exact subsidy at closing, usually through a dedicated escrow account controlled by the servicer.

A 3-2-1 buydown is the same concept stretched one year further. The first-year payment is modeled at 3% below the note rate, then 2% below in year two, then 1% below in year three before the full rate begins.

The three-year subsidy totals about $17,907, which is why 3-2-1 buydowns are less common than 2-1s. The upfront cost is meaningfully higher, so sellers and builders usually prefer the cheaper two-year concession unless inventory pressure is severe.

The buyer enjoys the lower early payment, but the subsidy has to come from somewhere. In 2026, the most common payer is the seller or builder. Builders like buydowns because they preserve headline pricing and neighborhood comps while still creating a real affordability story for the buyer.

Existing-home sellers may prefer a buydown over a price cut for the same reason. The concession can help the deal close without dragging the comparable sale price down for the next listing. Lender-paid buydowns exist too, but they are usually baked into a slightly higher permanent note rate somewhere else in the structure.

If the buyer is paying the subsidy from their own funds, the comparison gets tougher for the temporary buydown. A buyer-funded temporary buydown often loses to permanent discount points over a longer hold period because the temporary savings disappear while the points keep working.

This is the most important negotiation question. Suppose the seller is willing to spend about $10,000. Should you ask for a 2-1 buydown or a price cut?

A $10,000 price reduction lowers the loan amount and creates about $63/month of payment savings at the 6.52% note rate. The savings are smaller upfront than the 2-1 buydown, but they last for the full life of the loan.

The temporary buydown wins on short-term cash flow. The price reduction wins on long-term economics. That means the buydown is strongest for buyers who expect to refinance, move, or materially improve income within a few years. The price reduction is usually better for buyers who plan to keep the mortgage for a long time.

Most lenders qualify the borrower at the full note rate, not the discounted buydown rate. That is an important guardrail. A 2-1 buydown is meant to smooth the first years of ownership, not to sneak a borrower into a loan that stops working as soon as year three starts.

In practical terms, the lender usually wants to know you can handle the permanent payment of about $2,534/month in this example even though the early payments are lower. If you only qualify because of the discounted year-one payment, the structure is probably too fragile.

In many standard temporary-bydown structures, the unused subsidy balance is returned to the borrower or applied at payoff if the loan is refinanced before the buydown period ends. That is one reason a temporary buydown can work well for buyers who think rates may fall in the next couple of years.

That said, contracts matter. Some builder packages include special language, and some lender promos have quirks that deserve a close read. Never assume the leftover escrow balance behaves the same way in every buydown agreement without confirming the actual documents.

A temporary buydown and a hybrid ARM both lower the initial payment, but they do it very differently. A buydown is a payment subsidy on top of a fixed-rate mortgage. An ARM is a loan whose own interest rate is contractually fixed for a few years and then resets based on an index and margin.

The temporary buydown is usually easier to reason about because the step-up schedule is known on day one and the final stop is simply the original fixed note rate. The ARM introduces a more open-ended rate path after the fixed period ends.

If you want a deeper side-by-side on that trade, use the ARM vs fixed-rate guide.

The 1-0 buydown is exactly what it sounds like: the payment is modeled 1% below the note rate for the first year only, then the borrower moves straight to the full note rate in year two.

At the 6.52% note-rate example, that means year one is calculated at 5.52%, for a payment of about $2,276/month. The annual subsidy is much smaller than a 2-1, so some sellers prefer it when they want to help but do not want to spend nine or ten thousand dollars on the concession.

The cleanest way to ask is not "Can you help with my rate?" It is a specific concession request in dollar terms. For example: buyer requests a seller-paid 2-1 temporary buydown not to exceed a stated amount, funded through escrow at closing.

On conventional primary-residence loans, seller-contribution caps are usually structured around the down payment and occupancy profile. A common planning shorthand is 3% for low-down primary scenarios, 6% in mid-range cases, and up to 9% on larger down-payment owner-occupied transactions. The exact cap depends on loan type and structure, so the lender should validate the real limit before you rely on it.

For VA loans, concessions have their own rules and a separate 4% concession cap framework, even though many ordinary closing costs are negotiated differently. Product type matters here, which is why the lender should confirm the exact room before the request hits paper.

Temporary buydowns show up most often where sellers or builders need a payment story to get buyers over the line. In New Jersey, some resale sellers use them to compete without cutting the asking price. In California, Texas, and Florida, builders in newer communities often use 2-1 buydowns as a standard inventory-moving tool. In New York suburbs, concession structure depends heavily on local supply conditions and co-op versus condo versus single-family context.

The temporary-bydown funds are typically placed into a dedicated escrow account at closing. Each month, the servicer draws from that escrow to make up the difference between the reduced borrower payment and the full fixed note payment.

The borrower usually does not have to do anything special each month. The statement simply reflects the reduced required payment during the buydown period, and the servicer handles the subsidy transfer internally until the escrow is exhausted.

Temporary buydowns and permanent discount points solve different problems. Temporary buydowns front load the savings. Points spread the savings over the full life of the loan.

On a $400,000 loan, one discount point costs about $4,000. If it lowers the rate by 0.25%, the monthly principal-and-interest savings are roughly $65/month, which implies a break-even near 61 months.

Buyers expecting to keep the mortgage for a very long time often like permanent points better. Buyers expecting to refinance or move within a few years often value the short-term cash-flow relief of the temporary structure more.

To model a temporary buydown, run the mortgage calculator at the full note rate first. Then run the same home at 4.52% and 5.52%. The payment differences between those runs show you the year-one and year-two relief.

If you expect to refinance before year three, use the refinance calculator to test what kind of market drop would justify exiting the loan early.

If someone is offering you a buydown, confirm four things before you treat it as a win. First, who is actually funding it. Second, whether unused escrow is returned if you refinance early. Third, whether you qualify at the note rate or only because the early payment is lower. Fourth, what the alternative price-cut option looks like.
