What Is a 2-1 Buydown? Lower Your Mortgage Rate for Two Years

A 2-1 buydown is a way to lower your mortgage payment for the first two years of the loan, often paid for by the seller or builder. It's one of the most useful tools in a higher-rate market, but only when the math fits your situation.

How a 2-1 Buydown Works

Your interest rate is temporarily reduced for the first two years, then settles at the full note rate for the rest of the loan:

• Year 1: rate is 2% below your locked rate
• Year 2: rate is 1% below your locked rate
• Years 3–30: your full, permanent rate

An Example

Say your permanent rate is 6.5% on a $500,000 loan. With a 2-1 buydown you'd pay as if the rate were 4.5% in year one and 5.5% in year two, saving several hundred dollars a month early on, before stepping up to 6.5% in year three. The savings are deposited into an escrow account at closing and applied to your payments automatically.

Who Pays for It

The cost (the difference between the reduced and full payments) is funded upfront, usually as a seller or builder concession negotiated into the deal. In a buyer's market, asking the seller to fund a buydown is often more valuable to you than a small price cut. Lenders and builders sometimes offer them as incentives too.

Temporary Buydown vs. Buying Points

A 2-1 buydown is temporary. If you want a permanently lower rate, that's a different tool, paying discount points to buy the rate down for the full loan term. Points make sense if you'll keep the loan a long time; a 2-1 buydown makes sense if you expect your income to rise or plan to refinance within a couple of years.

When a 2-1 Buydown Makes Sense

Consider it when you expect rates to fall (so you can refinance into the permanent lower rate), when your income will grow into the full payment, or when a seller is willing to fund it instead of dropping the price. It eases you into homeownership without overpaying for the house itself.

The Fine Print

You still have to qualify at the full note rate, not the reduced one, so a buydown won't stretch your approval. And if you sell or refinance before the buydown period ends, any unused funds are credited back toward your loan. We'll model the exact numbers so there are no surprises.
