Temporary Buydowns Explained: 2-1, 1-0, and Seller-Paid Payment Relief
A temporary buydown lowers the payment for the first year or two, but the actual loan rate does not disappear. The full payment is waiting on the schedule.
TL;DR
- A 2-1 buydown reduces the effective payment rate by 2 points in year one and 1 point in year two.
- A 1-0 buydown reduces the payment for one year.
- The seller, builder, or lender usually funds the subsidy account.
- Borrowers typically qualify at the full note rate.
- A buydown is useful when near-term cash flow matters more than permanent monthly savings.
What a temporary buydown is
A temporary buydown is an upfront subsidy that lowers the borrower's payment for a short period. The note rate remains the actual interest rate on the mortgage, but money is placed into a buydown account at closing. Each month during the buydown period, that account covers the difference between the reduced payment and the full note-rate payment.
In a 2-1 buydown, the payment is calculated as if the rate were 2 percentage points lower in year one and 1 percentage point lower in year two. In year three, the borrower pays the full note-rate payment.
In a 1-0 buydown, the payment is reduced for only the first year.
Example
Assume a $400,000 loan at a 6.75% note rate.
| Year | Payment based on | Approximate P&I payment | | --- | --- | --- | | Year 1 | 4.75% effective payment rate | $2,087 | | Year 2 | 5.75% effective payment rate | $2,334 | | Year 3+ | 6.75% note rate | $2,594 |
The buydown account covers the difference between the reduced payments and the full $2,594 principal-and-interest payment during years one and two. Taxes, insurance, HOA dues, and mortgage insurance are separate and still apply.
Temporary buydown vs. discount points
A temporary buydown and discount points are different tools.
Discount points permanently reduce the note rate. They can make sense when the borrower expects to keep the loan long enough to recover the upfront cost through monthly savings.
Temporary buydowns reduce the early payment only. They can make sense when the borrower expects income to rise, wants moving-year breathing room, or negotiates seller concessions that cannot otherwise be used more efficiently.
| Tool | Best for | | --- | --- | | Temporary buydown | Short-term payment relief | | Discount points | Long-term payment reduction | | Seller price cut | Lower loan amount and property basis | | Seller closing credit | Reducing cash needed at closing |
Why sellers and builders use buydowns
In a slower market, sellers may prefer a buydown over a price reduction because it can make the monthly payment feel more manageable without lowering the public sale price. Builders use buydowns heavily because they can advertise lower first-year payments while protecting community price comps.
Borrowers should still do the math. A $12,000 seller credit could fund a buydown, pay closing costs, permanently buy down the rate, or reduce the price. The best use depends on the borrower's cash position and expected holding period.
Qualification and payment shock
Most borrowers qualify at the full note-rate payment, not the temporary payment. That is a consumer-protection feature. If the file only works at the reduced first-year payment, the payment jump in year two or three could create trouble.
Before accepting a buydown, ask yourself whether the full payment is comfortable today. If the answer is no, the buydown may be masking affordability rather than solving it.
Risks to watch
- Confusing the effective payment rate with the actual note rate. The note rate controls the long-term loan.
- Ignoring taxes and insurance. A reduced principal-and-interest payment can be offset by rising escrow.
- Assuming a refinance will be available. Rates, home values, credit, income, and guidelines can change.
- Using borrower cash for a temporary benefit. If you are paying for the buydown yourself, compare it against points and emergency reserves.
- Not reading the buydown agreement. The treatment of unused funds matters if you sell or refinance early.
When it can be smart
A temporary buydown can be useful for a borrower who has stable qualification at the full payment but wants lower early payments while rebuilding savings after closing. It can also be a good use of seller concessions when closing costs are already covered and the borrower does not expect to keep the loan long enough for discount points to break even.
It is not a substitute for affordability. Treat it as a cash-flow cushion, not as permission to buy a home whose real payment does not fit.
