The Complete Guide to Rate Buydowns: 2-1, 3-1, and Permanent Options
By Brent Reiter, REALTOR® · Last updated August 24, 2026
If you're buying a home — especially new construction — you've probably heard the term "rate buydown" thrown around as an incentive. Builders and sellers use them to make a home more attractive without simply cutting the price. But not all buydowns work the same way, and picking the right one (or knowing whether to skip one altogether) depends entirely on your situation. Here's a full breakdown.
What Is a Rate Buydown?
A rate buydown is a way to lower your mortgage interest rate — either temporarily or permanently — by paying money upfront at closing. That money can come from you, the seller, or the builder, depending on how the deal is structured.
There are two categories: temporary buydowns (2-1 and 3-1) and permanent buydowns. They solve different problems, so it's worth understanding both before deciding which — if either — makes sense for you.
Temporary Buydowns: 2-1 and 3-1
Temporary buydowns lower your payment for the first few years of the loan, then step back up to the full note rate for the remainder of the term. Your actual interest rate on paper doesn't change — instead, someone funds a subsidy that covers the difference in your payment during the reduced-rate period.
2-1 Buydown
- Year 1: 2% below note rate
- Year 2: 1% below note rate
- Year 3+: Full note rate
3-1 Buydown
- Year 1: 3% below note rate
- Year 2: 2% below note rate
- Year 3: 1% below note rate
- Year 4+: Full note rate
Example: If your note rate is 7%, your effective rate would be 5% in year one, 6% in year two, and 7% from year three on.
Who Temporary Buydowns Make Sense For
- Buyers who expect their income to rise in the next 2-4 years
- Buyers who plan to refinance if rates drop, and just need breathing room in the meantime
- Buyers who want lower payments early on — first year of homeownership often comes with extra costs (furniture, moving, repairs)
The Catch
You need to qualify (and budget) for the full note-rate payment, not the reduced one — lenders underwrite you based on your ability to afford the eventual full payment, not the discounted year-one number. And if rates don't drop and you don't refinance, your payment will step up as scheduled regardless of your financial situation at the time.
Permanent Rate Buydowns
This is a fundamentally different tool. Instead of a temporary discount that phases out, a permanent buydown lowers your interest rate for the entire life of the loan — from your first payment to your last.
How It Works
You (or the builder/seller) pay for discount points upfront at closing. Each point typically costs 1% of the loan amount and generally lowers your rate by roughly 0.25%, though this varies by lender and market conditions.
Example (as of Oct. 5, 2026): On a $400,000 loan at a starting rate of 6.71% (today's market average), here's how buying points could play out:
| Points Bought | Cost | Illustrative Rate | Monthly Payment | Monthly Savings | Break-Even | 30-Year Net Savings* |
|---|---|---|---|---|---|---|
| 0 (no points | — | 6.71% | $2,584 | — | — | — |
| 1 point | $4,000 | 6.46% | $2,518 | $66 | ~5.0 years | ~$19,800 |
| 2 points | $8,000 | 6.21% | $2,452 | $131 | ~5.1 years | ~$39,300 |
| 3 points | $12,000 | 5.96% | $2,388 | $196 | ~5.1 years | ~$58,500 |
*Net of the upfront point cost, assuming you keep the loan the full 30 years. That's illustrative, not a quote — a particular lender could offer a larger or smaller reduction per point, and pricing isn't always perfectly linear as you buy more.
The pattern worth noticing: the break-even timeline barely moves between 1, 2, and 3 points — it's the long-run savings that scale up. That makes the real question less "can I afford the points" and more "how long do I realistically expect to keep this loan."
Before paying points, ask your lender for side-by-side scenarios showing:
- The interest rate with no points
- The cost of each lower-rate option
- The resulting monthly payment
- The total interest over your expected ownership period
- The break-even point
If you expect to sell or refinance before reaching that break-even point, paying discount points may not be the best use of the money.
Who Permanent Buydowns Make Sense For
- Buyers planning to stay in the home long-term (this is the single biggest factor)
- Buyers who want payment certainty rather than a payment that changes year to year
- Buyers who have the extra cash at closing and would rather reduce long-term interest costs than keep that money liquid
The Catch
The math only works if you stay in the loan long enough to "break even" on the upfront cost. If you sell or refinance within a couple of years, you may not recoup what you paid for the points. This is where run the numbers matters most — good lenders can calculate your exact break-even point in months/years.
2-1 vs. 3-1 vs. Permanent: Quick Comparison
| Feature | 2-1 Buydown | 3-1 Buydown | Permanent Buydown |
|---|---|---|---|
| Rate reduction | Temporary, 2 years | Temporary, 3 years | Permanent, full loan term |
| Payment pattern | Steps up after year 2 | Steps up after year 3 | Stays the same |
| Best for | Short-term relief, expect income growth | Bigger short-term cushion | Long-term homeowners |
| Risk | Payment increases even if income doesn't | Same, over a longer runway | Upfront cost may not pay off if you move soon |
| Who typically pays | Builder, seller, or buyer | Builder, seller, or buyer | Builder, seller, or buyer |
New Construction Plays a Different Game Entirely
If you're weighing new construction against resale, there's a structural reason new builds deserve a closer look right now: many large builders own their own mortgage company, and that changes the math in your favor.
D.R. Horton's captive lender, DHI Mortgage, isn't a separate business — it's part of the same company selling you the house. That's why 73% of D.R. Horton's closings nationally now carry some form of rate buydown, and 90% of buyers who finance through DHI Mortgage specifically get one. The builder has been advertising mortgage rates commonly running 1–1.5% below prevailing market rates — a different starting point than what an independent lender quotes on a resale purchase.
Here's why builders can do this when a typical seller can't: a rate buydown doesn't show up as a lower sale price. If a builder cuts $20,000 off the price of a home, that becomes the new comp for every future sale in that community — it drags down the value of every other home the builder still has to sell there. Subsidizing the loan instead costs them real money, but it never appears on paper as a lower sales price, so it doesn't damage their own comps. That's the whole reason builders lean on financing incentives instead of price cuts.
Some of the rates builders advertise right now go even lower — but read the fine print. It's common to see builder marketing around rates as low as 4.5% on new construction. In almost every case, that's the first-year rate under a "2-1 temporary buydown," not a permanent rate. Here's how that actually works on a $400,000 loan with a 6.5% note rate:
| Year | Rate | Monthly Payment | Monthly Savings vs. Note Rate |
|---|---|---|---|
| Year 1 | 4.5% | $2,027 | $502 |
| Year 2 | 5.5% | $2,271 | $257 |
| Year 3 onward | 6.5% (full note rate) | $2,528 | — |
That's a real $9,100+ in savings over the first two years — valuable, especially for a buyer expecting income growth or a refinance down the road. But it's critical to know: you must qualify at the full note rate (6.5% in this example), not the temporary year-one rate, and the payment jumps back up starting year three. It's a bridge, not a permanent fix — which is a very different conversation than the permanent buydown numbers above.
Some builders go further and buy the rate down permanently, not just for year one. It's increasingly common to see builder-advertised permanent rates around 4.99% — a different offer than the temporary 4.5% example above, since this one doesn't reset. On that same $400,000 loan, 4.99% instead of today's 6.71% market average works out to about $2,145/month instead of $2,584 — a savings of roughly $439 every month, for as long as you hold the loan. Over a full 30-year term, that's over $158,000 in interest saved. The builder is typically paying a substantial amount in points upfront to secure that rate on your behalf, which is exactly why it's worth asking any builder directly what their preferred lender's permanent rate options look like, not just the flashiest year-one number in their ad.
Who Actually Pays for the Buydown?
This varies by deal:
- Builders frequently offer buydowns (temporary or permanent) as an incentive to move new construction inventory, especially in a higher-rate environment — often at little to no extra cost to you, baked into the deal.
- Sellers in a resale transaction may agree to fund a buydown as a negotiating concession, especially in a buyer's market.
- Buyers can also choose to pay for points themselves if neither the builder nor seller is offering it, particularly for a permanent buydown.
Always clarify who's funding it and confirm the true numbers — sometimes a "seller-paid buydown" is really priced into a slightly higher purchase price, so it's worth comparing the all-in cost carefully.
Could the Seller Pay for the Buydown?
Depending on the loan program, contract terms, appraisal, and applicable concession limits, a seller may be able to pay some or all of the discount-point cost through a negotiated seller concession.
That can benefit both sides:
For the buyer
The buyer receives a lower monthly payment without covering the entire upfront cost.
For the seller
The seller addresses a major affordability concern without necessarily making a larger price reduction.
Immediate monthly relief
The concession may provide the buyer with more immediate monthly relief than applying the same dollars to a modest reduction in purchase price.
This is why seller concessions and rate buydowns are worth evaluating together — not treating either one as automatically better in every transaction.
The Real Question to Ask Before Choosing One
It's not "which buydown is best" — it's "how long do I plan to be in this house, and do I want a payment that changes over time, or one that's certain from day one?"
- Planning to move or refinance in a few years? A temporary buydown gets you savings now without paying for a permanent rate change you won't hold long enough to benefit from.
- Planning to stay long-term? A permanent buydown may save you significantly more over the life of the loan than a temporary dip in year one or two.
- Not sure? That's exactly the kind of conversation worth having with your lender and me together — running actual numbers against your specific loan amount, rate, and timeline instead of guessing.
Let's Run Your Numbers
Buydowns can be a great tool — but only when they're matched to your actual plans, not just taken because they're offered. If you're looking at new construction or considering an offer with a buydown incentive, I'm happy to walk through the real numbers with you and your lender so you know exactly what you're getting.

Frequently Asked Questions
What is the difference between a temporary and permanent buydown?
A temporary buydown (like a 2-1 or 3-1) lowers your rate for the first few years, while a permanent buydown (buying points) lowers your rate for the entire life of the loan.
Who pays for a rate buydown?
Buydowns can be paid for by the buyer, the seller, or the builder. In today's market, builder-paid buydowns are very common on new construction homes.
Is a rate buydown worth it?
It depends on how long you plan to stay in the home. A temporary buydown is great if you plan to refinance soon, while a permanent buydown saves more money over the long term if you stay put.
