A temporary rate buydown is exactly what it sounds like: someone, usually the seller, pays up front so your mortgage rate starts lower for the first year or two. Your monthly payment starts smaller and steps up to the full amount over time.
With 30-year rates averaging 7.40% the week of October 8 (Freddie Mac), it's one of the most useful tools buyers have right now. Here's how it works in plain English.
How a 2-1 buydown works
The most common version is the 2-1. Your rate is 2 points lower in year one, 1 point lower in year two, and back to the full rate from year three on. The seller's money sits in an account and covers the difference each month.
Here's a simple example: a $600,000 home, 10% down, a $540,000 loan at a 7.25% rate.
| Rate | Monthly principal & interest | Savings per month | |
|---|---|---|---|
| Year 1 | 5.25% | $2,982 | $702 |
| Year 2 | 6.25% | $3,325 | $359 |
| Years 3–30 | 7.25% | $3,684 | — |
That's about $12,700 in savings over two years, which is roughly 2.1% of the price, paid by the seller. Taxes, insurance and HOA fees come on top and aren't affected.
Example for illustration only. Your rate and numbers depend on your loan, credit and lender.
Buydown vs. a $30K price cut
Same home, two different asks: the seller pays for a 2-1 buydown at $600,000, or the seller drops the price $30,000 to $570,000. Both assume 10% down and a 7.25% rate.
| 2-1 buydown at $600K | $570K, no buydown | |
|---|---|---|
| Down payment (10%) | $60,000 | $57,000 |
| Monthly P&I, year 1 | $2,982 | $3,500 |
| Monthly P&I, year 2 | $3,325 | $3,500 |
| Monthly P&I, years 3–30 | $3,684 | $3,500 |
| Cost to the seller | about $12,700 | $30,000 |
Here's the honest read:
- The buydown wins early. You save about $8,300 in payments over the first two years, though you put $3,000 more down.
- The price cut wins long term. It pulls ahead around year six. Over 30 years, it saves about $53,600 in payments, and a lower price can mean a lower tax bill too.
- But the seller decides. A $30K cut costs the seller more than twice what the buydown does, so many sellers say yes to a buydown long before they'd say yes to $30K off.
- Compare equal dollars. If the seller put the same $12,700 toward a price cut instead, your payment would drop by only about $78 a month.
So if a seller will truly knock $30K off, that's usually the better deal. If they won't, a buydown is often the most payment relief you can get for the money they're willing to spend.
Who pays for it?
Usually the seller, as a concession negotiated into your offer. How much a seller can contribute depends on your loan type and down payment. Talk to your loan officer about what your loan allows, and let your agent negotiate the seller concession.
The fine print (read this part)
- You qualify at the full rate. Lenders approve you based on the year-three payment, not the discounted one (Newrez guidelines). That's a good thing: it protects you from buying more than you can carry.
- Your rate is fixed underneath. This isn't an adjustable-rate mortgage. The payment steps up on a set schedule and never goes above your note rate.
- If you refinance early, ask about leftover funds. If rates drop and you refinance during the buydown period, unused funds are typically credited toward your loan balance. Confirm how your lender handles it.
- Temporary vs. permanent. A permanent buydown (paying "points") lowers your rate for the life of the loan, but it costs more up front. Which is better depends on how long you'll keep the loan. We'll run both.
A real example: Olivia's buydown
Olivia bought in December 2024 with a 7.5% mortgage. The seller contributed toward a 2-1 buydown, so her payment was calculated at 5.5% in year one and 6.5% in year two. That saved her $629 a month in the first year.
Later, she refinanced into a 30-year fixed loan at 6.25%. Her unused buydown funds were applied to her loan balance, so she ended up with both a lower rate and a smaller loan.
One honest caveat: refinancing isn't guaranteed, and it comes with costs. Your home should fit your budget even if rates never change. But a well-negotiated seller contribution can make a meaningful difference.
Is a buydown right for you?
It tends to work well if you expect your income to grow, you're stretching a bit in the first couple of years (new job, new baby, moving costs), or you'd like breathing room while you settle in. It's not a fix for a payment you can't afford long term, and I'll tell you if that's the case.
