What Is a Mortgage Buy Down and How Does It Help Kauaʻi Buyers and Sellers?

The most common question I hear from buyers watching rates right now: Are they going to come down? They might. But a mortgage buy-down in Kauaʻi is what I show them instead. The seller can fund meaningful payment relief right now. No waiting for the Fed, no price cut, no change to the asking price.

The 30-year fixed rate averaged 6.43% nationally as of the week of July 2, 2026 (Freddie Mac Primary Mortgage Market Survey). This is one of the most underused tools in our market. Here’s how both structures work, with payment examples at price points that reflect where Hawaiʻi buyers are actually transacting.

I recorded a detailed walk-through of this with Meena Na, Mortgage Loan Officer at Barrett Financial Group (NMLS #1412826). She is Hawaiʻi Life’s preferred lending partner. The original conversation happened when rates were in the mid-7% range. The mechanics are unchanged.

What Is a Mortgage Buy Down in Hawaiʻi?

A mortgage buy-down is money paid at closing, by the buyer, the seller, or both. It secures a lower interest rate on the loan. A lower rate means a lower monthly payment. That affects what a buyer qualifies for and what a property costs to carry over time.

There are two types: permanent and temporary. 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 comes in points, where one point equals 1% of the loan amount. The rate reduction each point buys varies by lender, loan type, and market conditions. Your lender calculates the exact reduction for your specific scenario.

This structure works for primary residences, second homes, and investment properties. That makes it the most flexible option across Hawaiʻi’s mix of buyer types.

One practical application Meena highlights: a buyer right at the qualifying edge. On a conventional loan, the maximum debt-to-income ratio is 50%. Say a buyer comes in at 51%. The seller can contribute points to permanently lower the rate. That shrinks the monthly payment enough to bring the DTI into range. “It’s very property-to-property specific,” she notes. That is why this conversation always starts with the lender running 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. The seller typically funds this type through a credit, not 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 structuring the buy down.

One detail most buyers don’t know: if the buyer refinances before the temporary period ends, any unused portion of the seller’s credit doesn’t disappear. It applies as a principal reduction on the loan. That’s a meaningful difference from a permanent buy down. There, the upfront cost is gone 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. Confirm with your lender before structuring an offer around this type. Investment properties are not eligible.

What a Mortgage Buy Down in Hawaiʻi Looks Like at Current Price Points

To see what a mortgage buy down looks like in Hawaiʻi right now, here are three price points. They span Kauaʻi’s entry market through higher-end transactions, and similar ranges show up on Oʻahu, Maui, and the Big Island. Each assumes 20% down on a 30-year fixed rate. Figures are principal and interest only: taxes, insurance, and HOA are additional. Actual results vary by lender, credit profile, and loan terms.

At the $3M level, $3,015 per month in year-one savings is real carrying-cost relief. And the seller never moves the asking price. At any price point, the seller funds the 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 side of a mortgage buy down in Hawaiʻi often gets overlooked, and it shouldn’t. This is the comparison I come back to most often when a seller is considering a price reduction. What does that same dollar amount accomplish as a buy down credit instead?

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, 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 simple. 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. It can also net the seller more after closing costs.

“As a seller,” Meena 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 what pricing strategy looks like in the current Kauaʻi market, see Selling on Kauaʻi in 2026: What the Data Says About Pricing, Buyers, and Timing.

A Hawaiʻi-Specific Detail That Changes the Qualifying Math

Hawaiʻi assesses property taxes annually and collects them upfront. Lenders qualify buyers based on the property taxes currently on record. That creates a significant wrinkle in transactions across all the islands.

When a seller has been using a property as a rental, the county taxes it at the investor rate. Take Kauaʻi in fiscal year 2025–2026. Non-owner-occupied residential properties pay $5.45 to $9.40 per $1,000 of assessed value, depending on tier. Owner-occupants with a homestead exemption pay $2.59 per $1,000, a fraction of that rate (Source: Kauaʻi County Real Property Tax Division). Each county sets its own rates, but the investor-to-homestead gap shows up across Hawaiʻi.

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 based on the tax bill currently in place. That gap can push a buyer’s DTI just over the qualifying threshold.

A permanent rate buy down funded by the seller can close that DTI gap directly. No price reduction, no additional down payment. It’s one of the clearest use cases for this strategy in a Hawaiʻi transaction.

“It’s very common for me to get multiple emails with property-specific questions,” Meena notes. “‘Hey Meena, here’s the address, does this work?’ That’s exactly the right question to ask early in the process.”

Who Should Consider a Mortgage Buy Down in Hawaiʻi

The strongest candidates: buyers right at the qualifying edge. Also sellers who are weighing a price reduction and haven’t modeled the alternative. Beyond those, a mortgage buy down in Hawaiʻi 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 asking 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. Meanwhile, it saves the buyer more per month. For more on structuring a strong offer in the current market, see Crafting a Winning Offer: Mastering the Art of Securing Your Dream Kauaʻi Home.
