Estimates only. Figures are illustrative, are not a loan offer, a commitment to lend, or an advertisement of credit terms. Taxes, insurance, mortgage insurance and HOA dues are entered as estimates and your real numbers will differ. A temporary buydown has to be written into the purchase contract and funded at closing by the seller or builder.

How a temporary buydown works

A temporary buydown lowers the interest rate for the first few years of a mortgage, so the early payments are smaller. The rate is not permanently lower — the full note rate returns on a published schedule.

  • 2-1 buydown: The rate is 2% lower in year 1 and 1% lower in year 2, then the full note rate from year 3 onward.
  • 3-2-1 buydown: The rate is 3% lower in year 1, 2% lower in year 2 and 1% lower in year 3, then the full rate.
  • 1-1-1 buydown: The rate is 1% lower in each of years 1, 2 and 3, then the full note rate from year 4 onward.
  • 1-0 buydown: The rate is 1% lower in year 1 only, then the full note rate from year 2 onward.
  • Seller concession needed: The buyer's total savings, expressed as a percentage of the purchase price — the concession you need negotiated into the contract.
  • Best for: Buyers who expect their income to rise, or a market where sellers and builders are offering concessions to close.
