What Is a Temporary Buydown?
A temporary buydown is a financing arrangement in which the buyer's effective interest rate is reduced for the first one to three years of the loan, then reverts to the full note rate for the remaining term. The cost of the buydown — equal to the total monthly payment savings over the reduced-rate period — is typically paid upfront as a seller concession at closing.
Think of it as a negotiating tool that converts a seller's price reduction into something far more tangible: lower monthly payments during the years when your cash flow is tightest.
The Three Main Types
There are three standard buydown structures, each named for the rate reductions they provide:
| Buydown Type | Year 1 Rate | Year 2 Rate | Year 3+ Rate |
|---|---|---|---|
| 1/1 Buydown | Note Rate − 1% | Note Rate − 1% | Note Rate |
| 2/1 Buydown | Note Rate − 2% | Note Rate − 1% | Note Rate |
| 3/2/1 Buydown | Note Rate − 3% | Note Rate − 2% | Note Rate − 1% (Year 3), then Note Rate |
The "1/1" refers to the 1% reduction applied for two years. The "2/1" reduces by 2% in Year 1 and 1% in Year 2. The "3/2/1" reduces by 3%, then 2%, then 1% in successive years before reverting to the note rate.
Real Numbers: A $700,000 Loan at 6.25%
To make this concrete, here is what each buydown structure looks like on a $700,000 loan at a 6.25% note rate on a 30-year term:
| Buydown Type | Year 1 Payment | Year 1 Savings/Mo | Seller Credit Needed | |---|---|---| | 1/1 Buydown | $3,865 at 5.25% | $445/mo | ~$5,335 | | 2/1 Buydown | $3,444 at 4.25% | $866/mo | ~$15,732 | | 3/2/1 Buydown | $3,046 at 3.25% | $1,264/mo | ~$30,895 | | No Buydown | $4,310 at 6.25% | — | — |
The note rate payment of $4,310 per month is what the buyer pays from Year 2 (1/1), Year 3 (2/1), or Year 4 (3/2/1) onward. The buydown simply shifts those higher payments into the future — at the seller's expense.

Who Pays for the Buydown?
In the vast majority of cases, the seller or builder pays for the buydown as a closing cost concession. The buyer negotiates the seller credit as part of the purchase contract, and the funds are deposited into an escrow account at closing. The mortgage servicer draws from that account each month to make up the difference between the buydown payment and the full note rate payment.
The buyer does not pay a higher rate or a higher loan balance in exchange for the buydown. The note rate on the loan remains unchanged — the buydown is purely a payment subsidy funded by the seller credit.
In some cases, a lender may offer a lender-paid buydown as part of a promotional program, though seller-paid buydowns are far more common in purchase transactions.
How the Seller Credit Is Calculated
The math is straightforward: the seller credit equals the total monthly savings over the entire buydown period.
For a 2/1 buydown on a $700,000 loan at 6.25%:
- Year 1: $866/mo savings × 12 months = $10,397
- Year 2: $445/mo savings × 12 months = $5,335
- Total seller credit: $15,732
This is the exact amount the buyer should ask the seller to credit at closing. The seller is essentially prepaying the interest rate differential for the buydown period — and the buyer captures every dollar of it in lower monthly payments.
Why Ask for a Buydown Instead of a Price Reduction?
This is the question most buyers do not think to ask — and it is one of the most important in today's market.
Consider a $700,000 purchase. The seller offers a $16,000 price reduction, bringing the price to $684,000. At 6.25%, the monthly P&I payment drops from $4,310 to approximately $4,212 — a savings of about $98 per month.
Now compare that to a $16,000 seller credit applied as a 2/1 buydown. In Year 1, the buyer saves $866 per month. In Year 2, they save $445 per month. The total seller concession is identical, but the timing is radically different.
A price reduction spreads the savings thinly over 30 years. A buydown front-loads the savings into the years when buyers need cash flow the most — when they are moving in, furnishing a home, and adjusting to new expenses.
The psychology matters. A buyer who is stretching to qualify at 6.25% may be far more comfortable knowing their first-year payment is $866 lower per month. That breathing room in Year 1 and Year 2 can be the difference between a confident buyer and a stressed one.
The Cash Flow Argument
Most buyers are cash-constrained in the early years of homeownership. Down payment, closing costs, moving expenses, and immediate home needs all compete for the same dollars. A buydown addresses this directly by reducing the monthly obligation during the period of maximum financial stress.
By Year 3 or Year 4, when the full note rate kicks in, most buyers have settled in, potentially received raises, and adjusted their budget. The higher payment is more manageable at that point than it would have been on day one.
When a Buydown Makes Sense — and When It Doesn't
A temporary buydown is a strong negotiating tool in the right circumstances, but it is not always the optimal choice.
A buydown makes the most sense when:
- You expect your income to grow over the next two to three years
- You are cash-flow constrained in the early years of ownership
- You plan to stay in the home for at least three to five years
- The seller is motivated and willing to offer concessions
- Rates are elevated and you expect to refinance within three to five years — the buydown savings are yours to keep regardless of whether you refinance
A buydown may not be the best choice when:
- You plan to sell or refinance within the first year (you may not recoup the full benefit)
- The seller is unwilling to offer a large enough credit to fund a meaningful buydown
- You would benefit more from a price reduction that lowers your loan amount and long-term interest cost
- You are already at the top of your budget and the note rate payment is unaffordable regardless of the buydown
Hawaii-Specific Context: How Seller Credits Work
In Hawaii real estate transactions, seller credits (also called seller concessions) are a standard and accepted part of the purchase contract. They are negotiated in the purchase agreement and appear on the closing disclosure as a credit toward the buyer's closing costs.
Conventional loan guidelines generally allow seller credits of up to 3% of the purchase price for loans with less than 10% down, and up to 6% for loans with 10% or more down. VA loans allow up to 4% in seller concessions. FHA loans allow up to 6%.
In Hawaii's high-cost market, where median home prices in Honolulu regularly exceed $700,000, a 2/1 buydown seller credit of $16,000 to $25,000 is well within the allowable concession limits for most loan types. Buyers should work with their lender to confirm the specific concession limits for their loan program before negotiating.
It is also worth noting that in Hawaii's slower market segments — particularly higher-priced condos and single-family homes that have been sitting on the market — sellers are increasingly open to concession requests. A buydown ask is often more palatable to a seller than a price reduction because it does not affect the recorded sale price, which matters for comparable sales in the neighborhood.
Practical Advice for Hawaii Buyers
If you are purchasing a home in Hawaii and rates are elevated, here is a practical approach to incorporating a buydown into your negotiation:
Step 1: Calculate your buydown cost before making an offer. Use the RealityCents Buydown Calculator [blocked] to determine the exact seller credit needed for a 1/1, 2/1, or 3/2/1 buydown based on your specific loan amount and rate. This gives you a precise number to include in your offer.
Step 2: Frame the ask as a seller concession, not a price cut. Sellers are often more receptive to a credit than a price reduction. Present it as a closing cost credit equal to the buydown cost — most listing agents understand this structure.
Step 3: Confirm concession limits with your lender. Before finalizing the offer, verify with your lender that the seller credit amount is within the allowable limits for your loan type and down payment.
Step 4: Understand the note rate. The buydown does not change your note rate — the rate on your loan documents remains the full rate. Your qualifying payment for DTI purposes is also calculated at the note rate, not the buydown rate, for most loan programs.
Step 5: Plan for Year 3 (or Year 4). Know what your full note rate payment will be and make sure it is comfortably within your budget. If rates have dropped by then, you may be refinancing anyway — but plan as if you will not.
The Bottom Line
A temporary buydown is one of the most underutilized tools in a buyer's negotiating toolkit. In a high-rate environment, it converts seller concessions into immediate, meaningful payment relief during the years when buyers need it most. The math is transparent, the structure is straightforward, and the benefit is real.
