The Complete Guide to Rate Buydowns: 2-1, 3-1, and Permanent Options
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: On a $400,000 loan, one point would cost $4,000 upfront. If that point drops your rate from 7% to 6.75%, your monthly payment is lower for the entire duration of the loan — no reversion, no step-up.
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 |
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.
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.
