A rate buydown is exactly what it sounds like: you pay money upfront to get a lower interest rate. The question is whether the upfront cost is worth the long-term savings, or in the case of temporary buydowns, whether the structure matches your actual plans. There are three primary types, and each one serves a different purpose.
Permanent Buydown: Paying Points for a Lower Rate
A permanent buydown, paying discount points, reduces your interest rate for the entire life of the loan. One discount point equals 1% of the loan amount. On a $370,000 loan, one point costs $3,700. That typically buys down the rate by approximately 0.25%. Whether it's worth it depends entirely on your break-even timeline: divide the upfront cost by the monthly savings to find how many months until the cost is recovered.
Example: $3,700 upfront reduces payment by $60/month. Break-even: 62 months (about 5 years and 2 months). If you'll stay in the home and keep this loan for more than 5 years, buying the point makes financial sense. If you might refinance or sell in three years, you'll pay $3,700 to save only $2,160, a net loss.
The 2-1 Buydown: Temporary Rate Reduction
The 2-1 buydown reduces your rate by 2% in Year 1 and 1% in Year 2, then reverts to the full note rate from Year 3 forward. If your note rate is 7%, you pay 5% in Year 1, 6% in Year 2, then 7% starting in Year 3. This gives you significantly lower payments in the first two years as you settle into homeownership, then you're at the permanent rate.
The cost of a 2-1 buydown is approximately 2% of the loan amount, held in an escrow account that the servicer draws from to make up the rate difference in Years 1 and 2. On a $370,000 loan, that's about $7,400. This cost can be paid by the buyer, the seller (common in today's market as a negotiating tool), or the builder on new construction.
The 2-1 buydown makes strategic sense in specific situations: if you expect your income to increase by Year 3 (making the higher payment more comfortable), or if you expect to refinance before Year 3 ends (so you never actually reach the full rate). It also makes sense when the seller is funding it as a concession, essentially giving you a subsidized first two years.
The 1-0 Buydown: One Year of Relief
The 1-0 buydown reduces your rate by 1% in only Year 1, then jumps to the full note rate. Lower cost than the 2-1, smaller benefit. This is the simplest version of a temporary buydown and is sometimes used when the available negotiating budget is limited.
Who Pays for the Buydown
Permanent points (for a permanent buydown) can be paid by the buyer or the seller as a concession within the allowed concession limits. Temporary buydowns (2-1, 1-0) can be funded by the buyer, seller, or builder. In the current market, sellers often fund temporary buydowns as an alternative to price reductions. The economics can work well for both parties: the seller avoids setting a low comparable sale price; the buyer gets below-market payments in the critical first years.
Break-Even Calculation for Permanent Points
Upfront cost ÷ monthly savings = months to break even. Example on $370K loan: 1 point = $3,700, rate drops from 7.0% to 6.75%, monthly savings = $59, break-even = 63 months. If you plan to stay 10+ years, buy the point. If you're likely to refinance in 2–3 years when rates fall, don't.
Common Mistake
Paying discount points when the break-even timeline exceeds your expected stay in the home. I see buyers pay $10,000–$15,000 in points to buy their rate from 7.0% to 6.5%, with a break-even of 80 months, and then refinance or sell 36 months later. The points were wasted money. Run the break-even before you pay for any points.
Bottom Line
Permanent buydowns make sense if you'll stay long enough to recoup the upfront cost. Temporary buydowns (2-1, 1-0) make sense when seller-funded, when your income is expected to grow, or when you anticipate refinancing before reaching the full rate. Always run the break-even calculation before paying for any rate reduction.
