Temporary rate buydowns: pros and cons

Educational guide · Updated 2026

A temporary buydown lowers your mortgage rate for the first few years, then steps it back up to the full rate. It's different from buying discount points, which lower the rate permanently. Buydowns became popular when rates rose, often as a seller or builder incentive.

How they work

The most common structures are the "2-1" and "3-2-1" buydown. With a 2-1, your rate is 2% lower in year one, 1% lower in year two, then settles at the full note rate from year three onward. A 3-2-1 starts 3% lower and steps down over three years. The full loan rate is fixed the whole time — only the rate you actually pay is temporarily reduced, with the difference covered by an upfront fund.

Who pays for it

The cost of the buydown — the gap between the reduced payments and the full payments — is funded upfront, usually by the seller or builder as an incentive, sometimes by the buyer. The money goes into an escrow account that covers the difference each month during the buydown period.

The pros

A buydown eases you into the payment with lower costs in the early years — helpful if you expect your income to rise, or if a seller is offering to fund it as part of the deal (effectively a price concession that helps your cash flow). If rates fall, you might refinance before the buydown even ends.

The cons and the key caution

The big risk is qualifying for and counting on the lower initial payment, then being caught off guard when it steps up. You must still qualify at the full note rate, and you should budget for the full payment from day one — treat the early savings as a bonus, not your baseline. If you were betting on refinancing before the rate resets and rates don't cooperate, you're left with the full payment you may not have planned for.
