The 2-1 buydown gained traction when rates climbed from 3% to 7% and sellers needed a way to move homes without reducing list price. In 2026, with rates still elevated, it remains a useful tool for sellers who want to offer a compelling incentive and buyers who want near-term payment relief. Here is how it actually works and when to use it.
How a 2-1 Buydown Works
The note rate is fixed at whatever rate the loan closes at. A seller-funded concession goes into an escrow account. In year one, the payment is calculated at the note rate minus 2%. In year two, the payment is calculated at the note rate minus 1%. Starting in year three and for the remaining life of the loan, the borrower pays the full note rate. The escrow account subsidizes the difference in years one and two, then it is depleted.
Real Math on a $400,000 Loan at 7.25% Note Rate
- ✦Year 1 (5.25%): principal and interest payment of approximately $2,208 per month
- ✦Year 2 (6.25%): principal and interest payment of approximately $2,463 per month
- ✦Year 3 and beyond (7.25%): principal and interest payment of approximately $2,726 per month
- ✦Total buydown cost (escrow funded by seller): approximately $10,494
- ✦Seller can fund this amount as a concession in lieu of a price reduction
The Critical Qualifying Rule
The borrower does not qualify at the buydown rate. They qualify at the full note rate. This is the most common misunderstanding about 2-1 buydowns. If the note rate is 7.25%, the DTI is calculated at the 7.25% payment even though the borrower will pay only the 5.25% payment in year one. The buydown is a cash flow benefit, not an underwriting benefit. If the borrower cannot qualify at the full note rate, the buydown does not solve the problem.
When to Use a 2-1 Buydown
- ✦Sellers who are already willing to reduce price but want a marketing advantage
- ✦New construction with builder incentives: builders commonly fund 2-1 buydowns on inventory homes
- ✦Buyers who expect income growth over the next two years and want lower early payments
- ✦Markets where buyer demand is soft and sellers need differentiation
What Happens If the Buyer Pays Off or Refinances Early
Any unused funds in the buydown escrow account are credited to the borrower at payoff or refinance. If rates drop in year one and the buyer refinances, they recover the unspent portion. This makes the 2-1 buydown more flexible than a permanent rate buydown in a scenario where the borrower might refinance within two to three years.
