With rates in the mid-6% range, “buying down” your mortgage rate has become one of the hottest topics for first-time buyers. A rate buydown does exactly what it sounds like — it lowers your interest rate in exchange for an upfront cost. But there are two very different kinds, and knowing which is which (and, crucially, who pays) can save you real money. Here’s the full breakdown.
What is a mortgage rate buydown?
A buydown means paying money upfront to reduce your interest rate. Sometimes you pay for it; very often the seller or builder pays for it as an incentive to close the deal. There are two main types: temporary buydowns that lower your rate for the first few years, and permanent buydowns (discount points) that lower it for the entire life of the loan.
Temporary buydowns (2-1, 3-2-1, 1-0)
A temporary buydown reduces your rate for the first year or two, then it steps back up to the full “note” rate. The numbers in the name tell you how much and for how long:
- 2-1 buydown: Rate is 2% lower in year one, 1% lower in year two, then the full rate from year three on.
- 3-2-1 buydown: 3% lower in year one, 2% lower in year two, 1% lower in year three, then the full rate.
- 1-0 buydown: 1% lower in year one only.
How it works mechanically: the cost of the buydown is calculated upfront and held in an escrow account. Each month, that account covers the difference between your reduced payment and the full payment. If you sell or refinance before the buydown period ends, any unused funds are typically credited back toward your loan.
Example: On a loan with a 6.75% note rate, a 2-1 buydown means you pay as if the rate were 4.75% in year one and 5.75% in year two, before settling at 6.75% in year three. On a $300,000 loan, that’s meaningful monthly savings in the early years — often several hundred dollars a month.
The important caveat: you still qualify at the full note rate, and the discount is temporary. Temporary buydowns shine when a seller or builder pays for them (common in a slower market), or when you reasonably expect your income to rise or plan to refinance before the rate steps up.
Permanent buydowns (discount points)
A permanent buydown means buying discount points. Each point typically costs 1% of your loan amount and lowers your rate by roughly 0.25% — for the entire life of the loan. On a $300,000 loan, one point costs about $3,000.
Permanent buydowns make sense when you plan to stay in the home a long time, because the monthly savings eventually outweigh the upfront cost. The key number is your break-even point: divide what you paid by your monthly savings to see how many months until it pays off. Stay past that point, and every month after is pure savings.
Temporary vs. permanent: which is right for you?
| Situation | Better option |
|---|---|
| Seller is offering to pay for it | Temporary buydown (free to you) |
| You expect income to rise soon | Temporary buydown |
| You plan to refinance if rates fall | Temporary buydown |
| You’ll stay in the home many years | Permanent points |
| You want the lowest lifetime cost | Permanent points (if past break-even) |
Who pays for a buydown?
This is the part first-time buyers should not miss. Buydowns can be paid by:
- The seller — as a concession to close the deal (very common right now). See seller concessions.
- The builder — new-construction incentives frequently include a buydown.
- You, the buyer — paying points at closing for a permanent reduction.
If a seller offers to help with closing costs, directing that money toward a buydown can be more valuable than a small price cut, because it lowers your actual monthly payment rather than just shaving a little off the loan balance.
Pros and cons
Pros: Lower monthly payments (temporary or permanent); can be seller-paid; can make an otherwise tight payment affordable in the crucial early years; a temporary buydown can bridge you to an expected raise or a refinance.
Cons: Temporary savings end and the payment jumps, so you must be able to afford the full payment; permanent points cost real cash upfront that you only fully recoup if you stay past break-even; if you sell or refinance early, you may not recoup points (though unused temporary-buydown funds are typically credited back).
A quick decision example
Imagine a seller offers a $9,000 credit. You could take it as a price reduction (shaving a bit off your loan and payment), or apply it to a 2-1 buydown that cuts your payment by several hundred dollars a month for two years. If money is tight in your first years of ownership, the buydown often delivers more real-world relief — and you can still refinance later if rates fall.
Frequently asked questions
What is a 2-1 buydown?
A temporary buydown that lowers your rate by 2% in year one and 1% in year two before returning to the full rate. It’s often paid by the seller or builder.
Is a rate buydown worth it?
If the seller pays, almost always. If you pay, it depends on how long you’ll stay — permanent points pay off past their break-even point.
Can I refinance instead of buying down my rate?
Yes. Many buyers take a temporary buydown now and refinance later if rates fall, avoiding the cost of permanent points.
Do I qualify based on the lower buydown rate?
No. You must qualify at the full note rate, which ensures you can afford the payment once the buydown period ends.
The bottom line
A rate buydown can make your first mortgage more affordable — especially if you can get the seller or builder to foot the bill. Use a temporary buydown for early breathing room or if you expect to refinance, and permanent points if you’re settling in for the long haul and can clear the break-even.
