How Mortgage Rates Are Priced in Seattle: The Adjustments on Your File

How mortgage rates are priced comes down to four layers on every file: the market price for that loan type on that day, the adjustments Fannie Mae and Freddie Mac publish for the loan's features, the lender's own choices such as lock length, and the points or credits you pick. Two Seattle buyers on the same morning can get different rates because their files sit differently in those layers.

I get some version of this question every week. A buyer sees a rate in an ad, then sees a different number on their own quote, and wants to know which one is real. Both are. The advertised rate was priced for a specific, simple file: usually a detached house, a large down payment, a purchase, a 30-day lock. Your rate was priced for your file. The difference between them is not a mystery and it is not a sales trick. It is a published list of adjustments, applied in order.

This guide walks through how mortgage rates are priced, one layer at a time, with the Seattle situations that move a file from one row of the list to another: a Capitol Hill condo, a Wallingford duplex, a King County loan above the national baseline. It quotes no rate and no adjustment figure. Those change too often to print, and the only number that matters is the one priced for your file, subject to qualification.

Layer One: The Market Price Behind How Mortgage Rates Are Priced

Every lender starts the day with a rate sheet for each loan type: 30-year fixed conventional, 15-year fixed, FHA, VA, jumbo, and so on. Each sheet shows a range of rates and the price of each one. That base price comes from the bond market, mostly from what investors will pay for mortgage-backed securities that morning, and it can change during the day when the market moves.

I will not repeat the macro story here. The Eastlake rate read covers the four signals that move that base price, including Treasury yields and mortgage spreads. For this guide, the point is simpler: the base price is the same for everyone getting that loan type from that lender at that moment. Everything that makes your rate yours happens on top of it.

Layer Two: How Mortgage Rates Are Priced by Loan Feature

Most Seattle buyers take a conventional loan that a lender will sell to Fannie Mae or Freddie Mac. Both agencies charge the lender a one-time fee when they buy a loan, and the fee depends on the loan's features. Fannie Mae publishes its version as the Loan-Level Price Adjustment Matrix. Freddie Mac publishes its version as Exhibit 19, Credit Fees, in its Seller/Servicer Guide; the current edition was updated September 30, 2026, for loans settling on or after October 1, 2026.

The lender usually recovers that fee through your pricing, either as a slightly higher rate or as points at the same rate. That is why the fee shapes your quote even though you never see it as a line item. Freddie Mac's exhibit is also clear that these charges stack: a loan with several features is charged for each of them, and the total is the sum.

Each agency starts from a base grid that pairs loan-to-value with your credit history, then adds charges for specific features. Here is the list of features in Freddie Mac's current exhibit, with what each one looks at and where it tends to show up in Seattle.

Term matters too. Freddie Mac's base grids state that they do not apply to 15-year and 10-year fixed-rate loans, which is one reason shorter-term loans can price differently from a 30-year fixed on the same file. Fannie Mae's matrix covers the same kinds of features under its own layout and its own figures. Your lender's pricing engine reads whichever one fits the loan and the investor buying it.

Seattle Property Types That Change How Mortgage Rates Are Priced

Three Seattle situations move a file off the plain-vanilla row more than any others.

A condo. An attached condo unit can carry a feature charge that a detached house at the same price does not, once the loan-to-value is above the levels in the grid. That is pricing, separate from whether the building itself is approvable. If the building fails the agency review, the loan may need a different product altogether, which the non-warrantable condo guide covers. A larger down payment can move a condo file into a tier where the condo line drops away; whether that is worth the cash is a trade I run for clients on both sides.

A duplex or triplex. A two-to-four-unit property adds the number-of-units line above certain loan-to-value levels, and if you are not living in it, the investment line too. Unit count also changes the loan limit itself. The Seattle multifamily loan guide covers the limits by unit count and how occupancy reshapes the whole loan.

A high-balance loan. King County's 2026 conforming limit for a one-unit home is $1,063,750, above the national baseline of $832,750. A loan amount between those two figures is still conforming, but Freddie Mac prices it on its super conforming lines, which apply at every loan-to-value tier. That is why a $900,000 loan and an $800,000 loan on similar files can price differently even though both are conforming. The limit that applies follows the county where the property sits, not where you live. The high-balance versus jumbo guide covers when a jumbo loan prices better than a high-balance one.

Occupancy and Loan Purpose: Second Homes, Rentals, and Cash-Out

Occupancy is one of the heaviest lines in the grid. A second home and an investment property each carry their own charge at every loan-to-value tier in Freddie Mac's purchase grid, so even a large down payment does not erase it. That is why the occupancy you declare has to be the real one: it is priced, and it is verified. The second home guide covers what a lender needs to see for a cabin or lake property to qualify as a second home rather than a rental.

Loan purpose works the same way. A cash-out refinance has its own base grid and its own feature lines, and some features charge more on a cash-out loan than on a purchase. If you are weighing a cash-out refinance against a home equity line for a remodel, the HELOC versus cash-out guide compares the two, and the pricing of the first mortgage is part of that decision.

When the Agency Charges Are Capped for First-Time Buyers

The grids also have a floor. Freddie Mac's current exhibit caps credit fees at zero for eligible first-time homebuyers with income at or below 100 percent of area median income, or 120 percent in areas Freddie Mac designates as high-cost. It applies the same zero cap to Home Possible loans for borrowers at or below 80 percent of area median income, and to certain Duty to Serve loans. Eligibility is defined in a separate exhibit, so the lender checks the address, the income, and the borrower's history against it.

Fannie Mae's matrix carries its own waivers for its affordable programs. For a Seattle first-time buyer, that can mean the condo or loan-to-value lines that would otherwise apply simply do not. If you think you might be close to the income limit, ask your lender to check before you assume the price on a standard quote applies to you. The first-time buyer guide covers the program stack these caps sit alongside.

Layer Three: The Lender's Part of How Mortgage Rates Are Priced

On top of the agency charges, each lender adds its own pricing for choices you make on the file. Two matter most.

• Lock length. A longer lock protects you for longer, and it generally costs more than a shorter one. A 60-day lock for a long escrow or new construction is a different product from a 30-day lock. The rate lock guide covers lock periods, extensions, and float-downs.
• Escrow waiver. If you want to pay your own property taxes and insurance instead of having an escrow account, many investors charge a small adjustment for that waiver, because the loan carries more risk to them. The escrow account guide covers when a waiver is available and when it makes sense.

Lenders also differ in their own margins and in how they buy and sell loans, which is why the same file can price differently at two lenders on the same morning. That difference is the one worth shopping for, and it is the only one the agencies do not set.

Layer Four: Points or Credits Turn the Price Into Your Rate

After the first three layers, the lender has a price for each rate on its sheet for your file. The last step is yours. You can pay discount points for a lower rate, take a lender credit toward closing costs in exchange for a higher rate, or land near the middle with neither. Same file, same price, different structure.

That is the reason the rate alone cannot tell you whether a quote is good. The guide to comparing mortgage offers in Seattle shows where points and credits appear on the Loan Estimate and how to line up two offers on the same structure. The rate buydown guide covers permanent and temporary buydowns, including seller-paid ones.

FHA and VA Loans Follow a Different Pricing Path

Fannie Mae's matrix and Freddie Mac's exhibit apply to conventional loans sold to those agencies. FHA and VA loans are not priced off them. Their base pricing comes from the market for government-backed mortgage securities, and lenders and investors apply their own adjustments on top. FHA loans also carry FHA's mortgage insurance premium, and VA loans carry the VA funding fee unless the borrower is exempt; those are program costs, not rate adjustments. For a buyer with a smaller down payment or a condo in an FHA-approved building, an FHA or VA quote can price differently from a conventional one on the same day for exactly this reason. The FHA loans guide and the VA loans guide cover those programs.

Questions to Ask Once You Know How Mortgage Rates Are Priced

Once you know the layers, a quote becomes something you can interrogate rather than accept or reject.

1. What file was this priced for? Property type, occupancy, loan amount, down payment, and loan purpose. If any of them is wrong, the quote is wrong.
2. Which features are moving my price? A lender can tell you whether the condo, unit-count, or high-balance lines are in play on your file.
3. Would a different down payment change the tier? Sometimes a modest change crosses a loan-to-value line; sometimes it changes nothing.
4. Do I qualify for a first-time buyer or income-based cap? Ask before you assume standard pricing.
5. How many points, or how much credit, is in this rate, and for how long is it locked? Without those two answers, a rate is not comparable to anything.
