Seattle mortgage rate buydowns: 4 ways to lower payments

Permanent buydown requests filed more than two business days after loan reservation carry a 1.00% fee. The schedule changed the economics of rate reduction for state-subsidized borrowers, who had previously been able to attach buydowns to their loan packages at near-zero administrative cost.

Inside the broader Seattle market, the change narrowed the gap between WSHFC products and conventional financing, but it also raised the effective cost of every basis point bought down by low- and middle-income buyers in the Puget Sound region. Timing matters for permanent points. For temporary buydowns, the 0.50% charge needs to be treated as part of the transaction cost regardless of when the request is filed.

The four buyer-side instruments in active use resolve to three temporary structures and one permanent structure. On a $560,000 loan at a 6.5% note rate, a 2-1 temporary buydown holds the borrower’s payment at roughly $2,835 for twelve months and $3,178 for the next twelve, before reversion to the full $3,539 principal-and-interest figure in month 25. The upfront subsidy fund required to produce those reductions runs about $12,700.

That sum is the variable—the lever that determines whether a Seattle mortgage rate buydown reduces the borrower’s effective interest cost or merely shifts it to a counterparty willing to absorb it for marketing or transaction-velocity reasons.

Temporary Buydown Mechanics: 3-2-1, 2-1, and 1-0

All three temporary structures share one operational principle. A subsidy account, funded at closing, reimburses the lender for the interest differential between a reduced contract rate and the loan’s full note rate over a defined window. Once that window closes, the rate resets and the subsidy is exhausted.

The borrower signs the loan at the full note rate. The temporary structure does not rewrite that rate, and it does not guarantee that the payment will remain at the subsidized level after the first, second, or third year. It simply places money in an account that covers part of the scheduled payment during the agreed period.

The Year 1 cash-flow impact on a $560,000 loan at 6.5% is direct and quantifiable. A 2-1 buydown produces approximately $704 per month in year-one savings and $361 per month in year-two savings. A 3-2-1 produces roughly $1,069 per month in year one, $722 in year two, and $366 in year three. A 1-0 produces roughly $366 per month in year one and nothing thereafter.

Those monthly figures should not be treated as interchangeable. The $704 associated with a 2-1 is a year-one figure; it does not continue through the second year. The same applies to the larger first-year reduction under a 3-2-1. Breakeven has to be calculated against the actual subsidy schedule, not against the first-year saving multiplied across every month.

For the $560,000 example, the approximate cumulative savings look like this:

• 2-1: $704 multiplied by 12 months, plus $361 multiplied by 12 months, produces roughly $12,780 in total savings. Against an estimated $12,700 subsidy, breakeven arrives at approximately the end of month 24.
• 3-2-1: $1,069 multiplied by 12 months, plus $722 multiplied by 12 months, plus $366 multiplied by 12 months, produces roughly $25,884 in total savings. Against an estimated $25,500 subsidy, breakeven arrives at approximately the end of month 36.
• 1-0: $366 multiplied by 12 months produces roughly $4,392 in savings. The implied breakeven is approximately 12 months, assuming the subsidy is sized to that one-year payment reduction.

The practical conclusion is less dramatic than the first-year payment figures suggest. A 2-1 does not recover its subsidy in 18 months by applying the year-one savings alone. It reaches approximate breakeven over the full two-year subsidy period. A 3-2-1 is not a one-year recovery instrument; its stated subsidy and payment reductions point to a breakeven near the end of the third year. A 1-0, by contrast, is a roughly one-year instrument because both its benefit and its subsidy window end after twelve months.

A temporary buydown does not lower the note rate. It subsidizes the differential between a reduced rate and the note rate for a fixed period. At month 25, the borrower is back at the original payment on a 2-1.

That distinction matters when comparing temporary and permanent options. A temporary structure creates a lower payment now, but it leaves the borrower exposed to the full note rate once the subsidy ends. The borrower may refinance before that point, but a refinance is a future transaction, not a feature guaranteed by the original buydown.

The 3-2-1 is the most generous to the borrower during the subsidy window and the least likely to pencil out over a full 30-year hold if the buyer is paying for it personally. It can make sense when a builder or seller is funding the subsidy and the buyer expects either income growth or a refinance within three years.

The 1-0 is the leanest structure. It is useful for a buyer who needs temporary payment relief during the first year but does not want to spend a large credit on a three-year schedule. It can also fit a transaction where a seller concession is available but not large enough to support a full 2-1 or 3-2-1.

Permanent Rate Reductions: Buying Discount Points for Long-Term Savings

The permanent structure operates by purchasing discount points at closing. Each point costs approximately 1% of the loan amount and reduces the interest rate by approximately 0.25%. On the same $560,000 loan, one point runs $5,600 and produces a rate reduction that applies over the full loan term.

The breakeven math is mechanical. A 0.25% reduction on a $560,000 loan saves roughly $93 per month at current amortization. At a $5,600 upfront cost, breakeven arrives at approximately month 60. Two points cost $11,200, yield a 0.50% reduction, and produce roughly $186 per month in savings. The approximate breakeven remains month 60 because both the upfront cost and monthly benefit have doubled.

Three points cost approximately $16,800, yield a 0.75% reduction, and produce roughly $279 per month in savings. Under the same 0.25%-per-point assumption, the breakeven remains near month 60. This is a useful illustration of the model, not a promise that every lender will price the points on a perfectly linear curve.

Where lenders compress that curve to 0.125% per point, breakeven extends to approximately month 120. The borrower pays the same general percentage of the loan balance for a smaller rate reduction, so the long-term savings become less attractive. This is why the note rate attached to the points, rather than the number of points alone, has to appear on the loan estimate and be compared against the no-point option.

The cost of buying down mortgage rate in WA through discount points is also governed by the WSHFC schedule. A permanent buydown request filed more than two business days after loan reservation carries a 1.00% fee on the loan balance, applied to the buydown request itself. For a $560,000 loan, that is $5,600 of additional administrative cost layered on top of the discount points.

When the permanent buydown is locked in at loan reservation, the 1.00% late-request fee does not apply under the stated schedule. The timing rule is therefore material: a borrower considering points should have the request documented and priced at reservation, rather than assuming the decision can be added later without changing the economics.

Permanent buydowns are also subject to a categorical prohibition under the WSHFC House Key Opportunity program. Borrowers using that down payment assistance channel cannot pair their assistance with a permanent rate reduction. The restriction is structural, not negotiable, and has applied to reservations originated under the program’s published guidelines.

The same distinction should be kept in view for other assistance funds. Down payment assistance is not simply another pool of cash that can be redirected to points or a temporary subsidy. The source, program rules, and allowable costs determine whether the money can be used at all. A buyer may have access to seller or builder funds for a buydown while being prohibited from using the DPA proceeds for that purpose.

Builder and Seller Concessions in the Seattle Market

In the Puget Sound region, the subsidy fund required to execute a temporary buydown is rarely paid entirely from the borrower’s pocket. Two channels dominate: seller-paid rate buydown Seattle transactions funded from the seller’s net proceeds, and builder incentives attached directly to new construction.

The Taylor Morrison Seattle offering, active in August 2026, is representative. The builder advertised up to $50,000 in flex cash on quick move-in homes in the Seattle metropolitan area, with authorization to apply the funds toward temporary buydowns, closing costs, or a combination of the two. Comparable programs have appeared from other production builders active in Snoqualmie, Issaquah, and the I-405 corridor.

The dollar magnitude is large enough to fund a full 3-2-1 buydown on the example loan and cover a substantial portion of ordinary closing costs. But the credit is not automatically available for every buyer, property, or loan structure. Builder incentives are usually tied to selected inventory, contract timing, preferred lenders, or other transaction conditions. The headline number is the ceiling, not a guaranteed cash payment.

A $50,000 builder flex credit can cover an estimated $25,500 3-2-1 subsidy on a $560,000 loan and approximately $8,000 in standard closing costs, but the remaining credit should not be described as an automatic permanent rate buydown.

The remaining credit depends on the builder’s written terms, the lender’s pricing, the type of loan, and the buyer’s actual closing costs. It may be available for other permitted costs, may be limited by concession rules, or may disappear if the buyer does not use the builder’s affiliated financing channel. There is no reliable basis for treating the residual—after the temporary subsidy and closing costs—as equivalent to a 1.0% permanent rate reduction. Under the article’s own 0.25%-per-point convention, a one-percentage-point permanent reduction on a $560,000 loan would cost approximately $22,400, not the roughly $16,500 left after the listed expenses.

On the resale side, the mechanics are similar but the magnitude is constrained by loan-to-value ratios and conforming loan limits. A seller concession of 3% to 6% of the purchase price is typical in King County, with the exact figure negotiated against days on market and the listing agent’s read on the buyer’s financing structure.

Concessions above 6% become uncommon in conventional financing because of secondary-market guidance. They can also become mechanically impossible in some FHA structures when the buydown is funded as a seller credit rather than as an allowable closing cost. The same nominal concession may therefore have a different usable value depending on the loan program.

The leverage point for the buyer is whether the concession is sized to cover the full buydown or only part of it. A partial subsidy produces a smaller monthly benefit in years one through three but preserves the note rate. The buyer still benefits from the rate environment at month 25 and beyond, because the payment returns to the original note-rate schedule rather than to a newly increased rate.

The buyer also has to compare the buydown with other uses of the credit. Closing costs, prepaid taxes and insurance, discount points, and a temporary subsidy may all compete for the same concession dollars. A 2-1 that absorbs the entire credit may be less useful than a 1-0 combined with a lower cash requirement at closing, particularly for a buyer whose reserves are thin.

WSHFC Guidelines and the 2025 Fee Structure

The Washington State Housing Finance Commission governs buydown treatment on loans originated through its first-time homebuyer, down payment assistance, and bond-funded channels. The fee timing is especially important because the temporary and permanent structures are not treated identically.

The working rules are:

• Temporary buydown requests carry a 0.50% fee on the loan balance, including requests made at loan reservation.
• The 0.50% temporary-borrowdown fee should therefore be included in the initial cost comparison rather than treated as a fee that disappears when the request is filed early.
• Permanent buydown requests filed at loan reservation do not carry the 1.00% late-request fee.
• Permanent buydown requests filed more than two business days after loan reservation carry a 1.00% fee on the loan balance.
• Down payment assistance funds cannot be applied to temporary or permanent buydown costs where the applicable program prohibits that use.
• The House Key Opportunity program prohibits permanent buydowns outright, regardless of timing.
• 3-2-1 buydowns under WSHFC are restricted to conventional loan products. Government-backed channels—FHA, VA, and USDA—are excluded.

For a $560,000 WSHFC-subject loan, the 0.50% temporary fee adds approximately $2,800 to the cost of a temporary buydown. A permanent request filed more than two business days after reservation adds approximately $5,600. On a smaller loan, the percentage impact is identical but the absolute figure scales down.

The temporary fee is not waived merely because the request is filed at reservation. That point changes the comparison with conventional financing. A borrower may still find the WSHFC product attractive because of its broader assistance or program terms, but the buydown calculation has to include the fee from the beginning.

The 3-2-1 temporary buydown is the deepest subsidy available in the Washington state housing market. It is also the most heavily restricted: conventional channel only, no government-backed pairing, and the full WSHFC fee included in the cost.

The mechanical impact of the 2025 schedule is to compress the cost differential between WSHFC products and conventional financing. The 0.50% fee applies to temporary requests whether they are filed at reservation or later. The 1.00% permanent fee creates a separate incentive to make the permanent-point decision before the two-business-day deadline.

That timing should be confirmed with the lender and documented in the loan file. Reservation, lock, and closing are not interchangeable events, and a borrower should not assume that a discussion with the loan officer has the same effect as a formal buydown request. The relevant question is when the request is considered filed under the originating channel’s procedures.

Financial Trade-offs: Temporary Versus Permanent

The choice between a temporary buydown and a permanent discount point purchase reduces to three variables: holding period, expected rate trajectory, and available subsidy funding.

Holding period is the strongest determinant. A borrower who expects to hold the loan for less than approximately 60 months does not reach the breakeven point on a single discount point under the example pricing. A temporary structure can reach its own breakeven only if the borrower receives the full subsidy period: approximately 24 months for the stated 2-1 example, approximately 36 months for the stated 3-2-1, and approximately 12 months for the stated 1-0.

Those are not interchangeable break-even claims:

The temporary figures assume the stated payment reductions and do not account for refinancing costs, changes in the loan balance, taxes, insurance, or the opportunity cost of funds. The permanent-point example assumes the lender maintains the stated 0.25%-per-point pricing relationship. Real loan estimates can produce a different result.

A buyer who expects to sell or refinance after ten months may still prefer a 1-0 if a seller or builder funds it. But if the buyer pays the subsidy personally, the transaction does not automatically make economic sense. The buyer would recover only part of the cost before the loan disappears or is replaced. The same logic applies to a 2-1 that is exited during the first year: the buyer receives the year-one payment reduction but not the second year needed to approach the stated breakeven.

Rate trajectory is the second variable. A borrower who expects the Federal Reserve to deliver 75 to 150 basis points of easing inside the next 18 months may reasonably prefer a 2-1 temporary buydown to paying for a permanent reduction. The temporary structure delivers cash-flow relief during the period of elevated rates, while a future refinance could deliver permanent relief if the borrower qualifies and the market cooperates.

That last condition is doing real work. A refinance requires sufficient income, acceptable credit, enough equity, and a rate reduction large enough to justify the new closing costs. A buyer should not choose a temporary buydown solely because a refinance feels likely. If rates remain elevated, the borrower reaches the end of the subsidy with the original full payment.

A borrower who expects rates to remain elevated or to rise is better served by locking a permanent point at today’s pricing if the originating lender offers a competitive discount curve and the borrower expects to hold the loan beyond the roughly five-year breakeven. Permanent points are also easier to evaluate when the buyer has a long-term plan and does not need the cash for reserves or other closing costs.

Subsidy funding is the third variable. In a transaction where the builder or seller is willing to fund the full buydown, the buyer’s decision becomes a comparison between the cash-flow benefit of the subsidy window and the residual flexibility of holding cash. In a transaction where the buyer funds the buydown personally, the comparison becomes a cost-of-capital calculation.

A buyer putting $12,700 into a 2-1 temporary buydown has to compare that use of capital with a larger down payment, a lower loan-to-value ratio, preserved emergency reserves, or another investment. The temporary payment reduction may be valuable, but it is not free simply because the money is paid at closing rather than through the monthly payment.

The Seattle-specific data point that matters in mid-2026 is the persistence of seller and builder concessions at magnitudes sufficient to fund temporary buydowns outright. The Taylor Morrison $50,000 flex program, comparable production-builder offerings, and the 3% to 6% seller-concession norm in King County together ensure that funded temporary buydowns remain available in parts of the market.

Availability is uneven, however. A new-construction incentive may be limited to quick move-in homes, while a resale concession depends on the seller’s negotiating position and the property’s time on market. A buyer should compare the concession against the price of the home and the financing terms rather than treating it as a standalone discount.

Permanent buydowns, by contrast, are priced too close to the breakeven horizon to dominate borrower decision-making at current note rates above 6% unless the buyer expects a long hold, has adequate cash, and receives a genuinely favorable point-to-rate conversion.

The Market Read

Temporary structures are the dominant tool for Seattle buyers in the current cycle. The funding is available, the payment relief is visible, and the rate environment has held elevated long enough to make the subsidy window genuinely valuable. But the economics are strongest when someone else funds the subsidy and the buyer expects to keep the loan through most or all of the scheduled window.

The 2-1 is the broadest middle ground. It gives the buyer two years of declining payment support without consuming as much credit as a 3-2-1. Its approximate breakeven is the end of the second year, not 18 months based on the first-year saving alone. The 3-2-1 is more powerful during the first year but requires the borrower to remain in the loan for roughly three years to recover the stated subsidy. The 1-0 is a one-year bridge and should be evaluated as such.

Permanent discount points remain a defensible choice for borrowers with confirmed long hold periods and access to capital at an opportunity cost below the effective loan rate. Under the example pricing, the five-year breakeven is clear and easy to test. If the lender’s discount curve is weaker, the same upfront payment can take much longer to recover.

The WSHFC fee schedule reinforces the need for precise timing and complete cost comparisons. Temporary buydowns carry the 0.50% fee even when requested at reservation. Permanent buydowns avoid the 1.00% late-request fee only when handled within the applicable reservation window. House Key Opportunity restrictions and the prohibition on using down payment assistance for buydown costs can remove an option before pricing becomes the issue.

Seattle mortgage rate buydown options will continue to skew toward 2-1 and 1-0 structures funded by seller and builder credits through 2026. Permanent points will remain a selective tool for borrowers with multi-decade horizons, sufficient reserves, and a loan estimate that supports the projected breakeven. The useful question is not which buydown produces the lowest payment in month one. It is who funds the reduction, how long the borrower will keep the loan, and what payment remains when the subsidy ends.
