A mortgage buy down on Kauaʻi is one of the most underused tools in the current market — one that can cut a buyer's monthly payment by hundreds to thousands of dollars, funded by the seller without touching the asking price. With rates holding in the mid-6% range as of May 2026, more buyers and sellers are asking how it works. The answer depends on the type of buy down and who's paying for it.
The breakdown below draws on a detailed conversation with Meena Na, Mortgage Loan Officer at Barrett Financial Group (NMLS #1412826), the preferred lending partner for Hawaiʻi Life. She recorded an in-depth explainer covering the mechanics, the math, and the scenarios where each structure makes sense. The strategy is the same — only the rate environment has shifted.
Rates referenced in the original recording were in the mid-7% range (September 2023). The examples below reflect current conditions. As of the week of May 19, 2026, the 30-year fixed rate averaged 6.51% nationally. Source: Freddie Mac Primary Mortgage Market Survey.
What Is a Mortgage Buy Down on Kauaʻi?
A mortgage buy down is money paid at closing — by the buyer, seller, or both — to secure a lower interest rate on the loan. A lower rate means a lower monthly payment, which affects what a buyer can qualify for and what a property costs to carry over time.
There are two types: permanent and temporary. Each works differently, and the right fit depends on the buyer's financial picture, the property's occupancy type, and what the seller is willing to contribute.
Permanent Buy Down: Lower Rate for the Life of the Loan
A permanent buy down reduces the interest rate for the entire loan term. Either party — buyer or seller — can pay for it. The cost is expressed in points, where one point equals 1% of the loan amount. The rate reduction that each point buys varies by lender, loan type, and market conditions — your lender calculates the exact reduction for your specific scenario.
This structure is available for primary residences, second homes, and investment properties.
One practical application Na highlights is a buyer right at the qualifying edge. On a conventional loan, the maximum debt-to-income ratio is 50%. A buyer who comes in at 51% may be able to qualify if the seller contributes points to permanently lower the rate — shrinking the monthly payment enough to bring the DTI into range. "It's very property-to-property specific," Na notes, which is why this conversation always starts with the lender running the actual numbers on a specific address.
Temporary Buy Down: Payment Relief for the First Years
A temporary buy down lowers the rate for a defined period before stepping back up to the note rate. The most common structures are the 2-1 and 3-2-1. This type must be funded by an interested party — typically the seller through a credit — not by the buyer directly.
In a 2-1 buy down at a 6.5% note rate:
- Year 1: Rate is 4.5% — two points below the note rate
- Year 2: Rate is 5.5% — one point below
- Year 3 through 30: Rate returns to 6.5%
The buyer qualifies based on the full 6.5% note rate — not the reduced year-one rate — so underwriting reflects the long-term obligation. The relief is real, but lenders confirm the buyer can carry the full payment before the buy down is structured.
One detail most buyers don't know: if the buyer refinances before the temporary period ends, any unused portion of the seller's credit isn't lost — it applies as a principal reduction on the loan. That's a meaningful difference from a permanent buy down, where the upfront cost is spent regardless of when the buyer exits the loan.
Temporary buy downs are available for primary residences. Eligibility for second home purchases can vary by lender and loan program — ask your lender before structuring an offer around this type of buy down. Investment properties are not eligible.
What a Mortgage Buy Down Looks Like at Kauaʻi Price Points
To make the math concrete, here's what a 2-1 mortgage buy down looks like at three Kauaʻi price points, each assuming 20% down on a 30-year fixed rate. Figures shown are principal and interest only — taxes, insurance, and any HOA are additional. Actual results vary by lender, credit profile, and loan terms.
| Purchase / Loan | 6.5% Note Rate | Year 1 at 4.5% | Year 1 Savings | Year 2 at 5.5% | Year 2 Savings |
|---|---|---|---|---|---|
| $875K / $700K loan | $4,425/mo | $3,550/mo | $875/mo | $3,975/mo | $450/mo |
| $1.5M / $1.2M loan | $7,590/mo | $6,080/mo | $1,510/mo | $6,815/mo | $775/mo |
| $3M / $2.4M loan | $15,175/mo | $12,160/mo | $3,015/mo | $13,625/mo | $1,550/mo |
At the $3M level, $3,015 per month in year-one savings is meaningful carrying cost relief — without the seller reducing their asking price by a dollar. At any price point, the seller funds a credit, and the buyer gets lower payments while rates hold at current levels.
Same Cost to the Seller, Three Times the Savings for the Buyer
The seller strategy built into a mortgage buy down is one of the most overlooked tools in the current market. The comparison that makes the case: $30,000 applied as a price reduction versus $30,000 applied as a permanent rate buy down credit.
At $1.5M with 20% down (a $1.2M loan at 6.5%):
- $30K price reduction: New loan is $1.176M. Monthly payment drops to approximately $7,436 — a savings of about $154 per month.
- $30K permanent buy down credit: The seller's $30K funds points that reduce the interest rate — your lender calculates the exact drop. The lower rate produces a meaningfully smaller monthly payment than the price reduction alone delivers.
The price reduction math is straightforward. The buy down math is almost always better for the buyer — and the seller nets the same purchase price either way. In some scenarios, a smaller credit applied to a buy down outperforms a larger price reduction while netting the seller more after closing costs.
"As a seller," Na explains, "if you're thinking about reducing your price and you're having that conversation with your realtor... these programs show you there may be a better option." For more on current pricing strategy, see Selling on Kauaʻi in 2026.
A Kauaʻi-Specific Detail That Changes the Qualifying Math
Hawaiʻi property taxes are assessed annually and collected upfront. Lenders qualify buyers based on the property taxes currently on record — which creates a significant wrinkle in Kauaʻi transactions.
When a seller has been using a property as a rental, it's taxed at the investor rate. On Kauaʻi for fiscal year 2025–2026, non-owner-occupied residential properties are taxed at $5.45 to $9.40 per $1,000 of assessed value depending on value tier. Owner-occupants with a homestead exemption pay $2.59 per $1,000 — a fraction of the investor rate. (Source: Kauaʻi County Real Property Tax Division.)
A buyer purchasing the property as their primary residence will eventually qualify for the lower homestead rate — but that requires a post-closing filing, and the lender qualifies the buyer based on the tax bill currently in place. That gap in monthly carrying cost can push a buyer's debt-to-income ratio just over the qualifying threshold.
A permanent rate buy down funded by the seller can close that DTI gap directly — without a price reduction or additional down payment. It's one of the clearest use cases for the strategy in a Hawaiʻi transaction.
"It's very common for me to get multiple emails with property-specific questions," Na notes. "'Hey Meena, here's the address — does this work?' That's exactly the right question to ask early in the process." For context on how Kauaʻi property complexity plays out across different transaction types, see Why Kauaʻi Real Estate Is Different.
Who Should Consider a Mortgage Buy Down on Kauaʻi?
The strongest candidates are buyers who are right at the qualifying edge — where a rate reduction closes a DTI gap — and sellers who are weighing a price reduction and haven't modeled the buy down alternative. Beyond those scenarios, a mortgage buy down on Kauaʻi tends to make sense when:
- The buyer has reserves but tighter monthly income — the permanent buy down lowers the qualifying payment
- The buyer expects higher income in the next one to two years — a temporary buy down provides near-term relief before the rate steps back up
- The buyer is purchasing a property currently taxed at the investor rate (the Hawaiʻi-specific qualifying scenario above)
- The seller has room to offer credits and wants to attract more qualifying buyers without adjusting the price
One note on occupancy: temporary buy downs require the property to be owner-occupied. Investment properties are not eligible. For second home purchases, eligibility can vary by lender and loan type — confirm with your lender before structuring an offer around a temporary buy down.
Buyers who have been waiting for rates to fall may not need to wait. A seller-funded buy down can create year-one payment relief that costs the seller less than a price cut — while saving the buyer more per month.
