What Is a 2-1 Buydown on a Conventional Loan — and Should You Ask for One?
A 2-1 buydown is a seller-funded strategy that temporarily reduces your mortgage rate for the first two years. It can be a useful negotiating tool — here is exactly how it works.
What is a 2-1 buydown?
A 2-1 buydown is an arrangement where a third party — typically the seller or real estate agent — deposits funds into an account that subsidizes your mortgage payment for the first two years. Your rate is reduced by 2 percentage points in year one and 1 percentage point in year two. In year three and beyond, you pay the full note rate for the remaining term.
Example: If your note rate is 7.0%, you pay 5.0% in year one, 6.0% in year two, and 7.0% from year three onward.
Who can fund the buydown?
On conventional loans, the buydown must be funded by the seller, builder, or real estate agent — an interested party to the transaction. The borrower cannot fund their own buydown. The buydown funds count toward the interested party contribution (IPC) limit for the transaction, subject to the same 3–9% caps based on LTV.
How is the borrower qualified?
This is a critical point many buyers overlook: you are qualified at the full note rate, not the reduced buydown rate. Even though your payment in year one reflects a lower rate, the lender confirms you can afford the full note rate payment. The buydown simply subsidizes the difference — it does not change your qualifying income or DTI.
What happens if you sell or refinance early?
If you sell or refinance before the buydown period ends, unused buydown funds can be returned to the borrower or to the lender, depending on the buydown agreement terms documented at closing.
What the subsidy costs (illustrative example, not a quote)
This uses a hypothetical $500,000 loan on a 30-year fixed term at a 7.0% note rate, matching the example above. Principal and interest comes to about $3,327 a month at 7%, about $2,684 at 5%, and about $2,998 at 6%.
| Year | Rate paid | Monthly P&I | Subsidy for the year |
|---|---|---|---|
| 1 | 5.0% | about $2,684 | about $7,709 |
| 2 | 6.0% | about $2,998 | about $3,945 |
| 3 and on | 7.0% | about $3,327 | none |
The seller would deposit roughly $11,650 to fund the two years. Those funds count toward the interested party contribution cap. At 90% loan-to-value or lower that cap is higher, but at above 90% it is 3% of the price. Your payment steps up twice, ending at the full $3,327 plus taxes and insurance. These are rounded, rate-based figures, not a quote.
Buydown or price reduction?
- A buydown helps cash flow early. It does nothing for the loan amount, closing costs, or the payment in year three.
- A price reduction helps for the life of the loan. It lowers the balance and the payment every month.
- Ask for both numbers. Have us price each approach so you can see which offers more value for the same seller dollars.
Planning for year three
Before you rely on the lower early payments, test the full payment against your budget. Do not plan around a refinance before year three, since it depends on your equity, credit, and the terms available then. If your income is likely to rise, or you expect to sell, the buydown can be a good fit.
Frequently asked questions
Can a buydown be combined with other seller credits?
Yes, but all seller-funded items share one cap, so the more you use for the buydown, the less is left for closing costs.
Does a buydown work the same as paying points?
No. A point equals 1% of the loan amount and permanently lowers the rate. A 2-1 buydown is temporary and ends after two years.
What if I pay off the loan in year two?
Depending on the buydown agreement, unused funds may be returned. Read the agreement, and confirm with your escrow officer.
