King County Home Loan Programs: A Complete Buyer's Guide

The Short Answer on King County Home Loan Programs

King County home loan programs in 2026 include a high-cost conforming ceiling of $1,063,750 set by the Federal Housing Finance Agency, federal FHA and VA loans, Washington State Housing Finance Commission first mortgages with down payment assistance, city of Seattle home buyer help, ARCH ownership programs on the Eastside, and employer benefits at Amazon, Microsoft, and several other large employers. Most buyers stack at least two.

I work with buyers across the county every week, and the question I hear most is some version of, "Which of these actually applies to me?" That depends on three things: where you are buying, what you earn, and how much you have to put down. The rest of this guide walks you through how the King County home loan programs fit together so you can spot the ones worth a closer look.

One ground rule before we start. Mortgage programs change. I will flag what is current as of 2026, but income limits, loan caps, and employer benefits are reviewed on their own schedules. When I cite a number, verify it before you commit, and assume any rate or payment example is illustrative until I have a full loan estimate in front of you.

Why King County Sits in Its Own Mortgage Category

King County home loan programs do not look like loan programs in most of the country, and the reason is price. The Seattle-Tacoma-Bellevue metro carries one of the highest FHFA county loan ceilings in the United States, which changes which products actually apply to buyers here.

The 2026 King County conforming loan limit

The 2026 one-unit conforming loan limit for King County is $1,063,750, current as of 2026 per the Federal Housing Finance Agency. That is the line between conforming or high-balance conforming financing and jumbo financing. Anything at or below the ceiling can be sold to Fannie Mae or Freddie Mac under standard conforming guidelines, and pricing tends to be more favorable than jumbo. Anything above it is jumbo, which means tighter credit, reserve, and documentation requirements, subject to credit approval.

What "high-cost area" means for King County home loan programs

FHFA designates a county high-cost when local median home values run well above the national baseline. King County qualifies for the high ceiling. The practical effect on King County home loan programs is that many Seattle and Eastside buyers can stay inside conforming territory on purchases that would force jumbo financing in cheaper markets. That matters for FHA loan limits too, because the FHA county ceiling tracks the conforming high-balance figure.

Jumbo threshold for Seattle, the Eastside, and the rest of King County

Once a loan crosses the King County conforming line, jumbo guidelines take over. Most floating homes in Eastlake and Portage Bay, most single-family homes in central Seattle and on the Eastside, and many lake-view condos cross the jumbo threshold. I cover jumbo specifics in the Seattle jumbo mortgages guide, but the headline is that jumbo programs are part of the King County home loan programs landscape whether buyers want them to be or not.

Federal King County Home Loan Programs: FHA, VA, and USDA

Three federal programs anchor the conventional alternatives in the King County home loan programs menu. Each carries its own credit, down payment, and property rules.

FHA loans in King County

FHA loans are insured by the Federal Housing Administration and accept credit scores as low as 580 with 3.5 percent down, subject to credit approval and FHA program rules. FHA is forgiving on credit history and debt-to-income ratios, which makes it a common path for first-time buyers in King County, especially on warrantable condos in Capitol Hill, the University District, and South Lake Union. The 2026 FHA loan limit in King County tracks the conforming high-balance ceiling, so most price points inside the city qualify. FHA carries mortgage insurance for the life of the loan in most current cases, which is the trade-off for the loose credit overlay.

VA loans in King County

VA loans are available to eligible veterans, active-duty service members, National Guard and Reserve members, and qualifying surviving spouses. The headline features are zero down payment up to the county ceiling, no monthly mortgage insurance, and competitive pricing, subject to qualification. King County is heavy with VA-eligible buyers because of Joint Base Lewis-McChord commuters to the south and Naval Base Kitsap commuters across the Sound, plus a large veteran population working in tech, healthcare, and city government. VA loans pair cleanly with WSHFC down payment assistance for closing-cost help.

USDA loans in King County

USDA Rural Development loans offer zero down for income-eligible buyers in designated rural areas. Most of King County is not USDA-eligible, but pockets in the rural south and east of the county, including portions of Enumclaw and the unincorporated foothills, may qualify, subject to USDA mapping and income limits. If you are buying outside the urban growth boundary, ask before you assume USDA is off the table.

How the Washington State Housing Finance Commission Fits Into King County Home Loan Programs

The Washington State Housing Finance Commission, or WSHFC, runs the state's flagship first-mortgage and down payment assistance offerings. King County buyers see WSHFC paired with FHA, VA, USDA, or conventional first mortgages more often than any other program in the county.

WSHFC Home Advantage in King County

Home Advantage is WSHFC's most-used program. It pairs a 30-year first mortgage with a down payment assistance second that can run as high as 5 percent of the loan amount, subject to program rules. King County income limits for Home Advantage are higher than the rest of Washington, reflecting county median income, so buyers who think they earn too much often still qualify. Verify the current limit at write time with WSHFC, and confirm purchase price caps for King County before locking pricing.

WSHFC House Key Opportunity in King County

House Key Opportunity targets lower-income first-time buyers with tighter income limits and slightly different first-mortgage pricing. It is less common in central Seattle because of price points, but I see it on King County purchases in Kent, Renton, Burien, Federal Way, and parts of Tukwila where prices fit the program math. House Key can layer with several WSHFC down payment assistance products.

WSHFC down payment assistance variations

WSHFC operates several specific down payment assistance products that overlay the Home Advantage or House Key first mortgages. Examples include the Home Advantage DPA, the Opportunity DPA, the HomeChoice DPA for buyers with disabilities, and the Veterans Down Payment Assistance program for qualifying Washington veterans. Each carries its own income, occupancy, and repayment rules, subject to program-level qualification.

For a deeper walk-through of these layers and how they apply specifically to Seattle buyers, see my Washington down payment assistance for Seattle buyers guide.

City and County Programs: ARCH and the Seattle Office of Housing

Beyond the federal and state offerings, two locally administered tracks deserve attention in any rundown of King County home loan programs. They serve different parts of the county and operate on different funding cycles.

ARCH ownership programs on the East King County side

A Regional Coalition for Housing, better known as ARCH, is a partnership of East King County cities and the county itself. Member jurisdictions include Bellevue, Kirkland, Redmond, Issaquah, Sammamish, Mercer Island, and several smaller cities. ARCH primarily supports the development and preservation of affordable units, including for-sale units that are restricted to income-eligible buyers, typically households at 80 to 120 percent of King County area median income.

From a financing standpoint, ARCH ownership units come with deed restrictions, resale formulas, and program-specific guidelines that affect which first mortgages can be used. Many ARCH-restricted units can be financed with conforming products that include a soft second, but the loan must respect the resale and occupancy rules. Confirm eligibility and available inventory directly with ARCH before structuring a loan around one of its units.

City of Seattle Home Buyer Assistance

The Seattle Office of Housing runs the City of Seattle Home Buyer Assistance program for income-eligible buyers purchasing inside Seattle city limits. The assistance is typically structured as a deferred or low-interest second mortgage that helps cover down payment and closing costs. It layers with FHA, VA, conventional, and WSHFC first mortgages. Funding availability and income caps move on the city's budget cycle, so verify current terms with the Office of Housing before counting on the program for a specific purchase.

City of Bellevue, Kirkland, and other Eastside city tracks

Bellevue, Kirkland, and several other Eastside cities participate in housing programs primarily through ARCH rather than running stand-alone down payment assistance loans for individual home buyers. If you are buying inside one of these cities and someone tells you the city itself has a direct down payment assistance loan, verify with the city's housing department before relying on it.

Seattle Multifamily Tax Exemption and what it does not do for buyers

The Seattle Multifamily Tax Exemption, or MFTE, comes up often in conversations about affordable housing in the city. MFTE is a rental program, not a home buyer program. Buyers should know it exists, because a building's MFTE status can affect a condo conversion or a buyer's renter neighbors, but MFTE itself does not help anyone purchase a unit.

Employer Down Payment Assistance Inside King County Home Loan Programs

One of the most overlooked corners of King County home loan programs is employer-provided assistance. Several of the county's largest employers offer some form of home buyer benefit, and many employees never check.

Major King County employer benefits to ask about

The list below covers employers that have historically offered home buyer benefits at some point. Programs change frequently, so confirm with your HR or benefits portal before relying on a specific dollar figure.

• Amazon (South Lake Union HQ and across the Eastside): has historically supported relocation packages; ask HR whether any home purchase or down payment benefit applies to your role.
• Microsoft (Redmond): has offered employee home loan and assistance programs for U.S. employees; verify current eligibility with HR.
• Boeing (Renton, Everett, Tukwila): relocation and home purchase support has varied by program and employee classification; confirm with HR.
• University of Washington (Seattle, Bothell, Tacoma): UW has historically offered faculty and staff housing assistance through specific programs; verify with UW HR.
• Starbucks corporate (SoDo HQ): confirm current home buyer or relocation benefits with HR.
• T-Mobile (Bellevue HQ): confirm with HR.
• Costco corporate (Issaquah HQ): confirm with HR.
• Expedia Group (Seattle Interbay HQ): confirm with HR.
• Fred Hutch, UW Medicine, Allen Institute, and SLU biotech employers: each runs its own benefits structure; ask HR.

Employer programs are powerful when they exist, because they stack on top of the rest of the King County home loan programs menu. They are also notoriously easy to miss. If your employer is on the list above or is comparable in size, ask HR before assuming you are limited to FHA, VA, or WSHFC alone. Programs change, so verify with employer HR each time.

How King County Home Loan Programs Apply by Neighborhood

Different parts of the county lean on different layers of the King County home loan programs stack. Here is how the menu maps to the neighborhoods I cover most.

Stacking King County Home Loan Programs: What Lines Up With What

Most buyers I work with end up combining at least two layers, sometimes three. The combinations that show up most often in King County home loan programs files are predictable once you see them a few times.

Common stacks I see across the county

FHA first mortgage with WSHFC down payment assistance is the workhorse stack for first-time buyers in Seattle, Renton, Kent, and Burien. VA first mortgage with WSHFC Veterans Down Payment Assistance shows up for service members and veterans across the county. Conventional first mortgage with WSHFC Home Advantage DPA covers many city buyers above the FHA loan amount sweet spot but still inside conforming. Conventional or jumbo first mortgage with employer DPA covers Amazon, Microsoft, and Boeing buyers where the employer benefit exists.

Stacks that need extra care

City of Seattle Home Buyer Assistance and WSHFC DPA can both sit in second-lien position. Pairing them requires careful coordination so the closing does not unwind because two programs both wanted the same priority. ARCH ownership units carry deed restrictions that limit which first mortgages can be used. Employer programs vary so widely that I always pull the actual benefit doc before structuring the file.

Income limits to verify on every King County file

King County income limits for WSHFC are higher than most of Washington, but they still exist. FHA, VA, and conventional loans without DPA do not have income limits at the loan level, though employer programs almost always do. ARCH targets 80 to 120 percent of King County area median income, depending on the unit. Seattle Office of Housing has its own income tiers. Every program-level income limit should be verified against current numbers before we commit to a structure, subject to program-level qualification.

How I Walk King County Buyers Through These Programs

My approach to King County home loan programs is the same whether you are buying a Wallingford craftsman, a Kirkland townhome, or an Eastlake condo. I start with your income, savings, credit, and timeline, then I work backward from the programs that fit your numbers. I am calm about it, I do not push, and I will tell you when a program someone mentioned is not the right fit so you do not waste cycles on it.

I have been doing this for more than twenty years, almost all of it in King County, and I have lived through enough rate cycles, FHFA limit changes, and program updates to know which combinations hold up at closing and which ones blow up in underwriting. I work out of Movement Mortgage's Eastlake office at 2701 Eastlake Ave E, Unit 105, and I take calls, emails, and in-person meetings across Seattle and the Eastside.

When you are ready, I will run your scenarios against the current King County home loan programs landscape and give you a clear picture of what you may qualify for, what to verify with HR or with WSHFC, and what your next steps look like. Subject to credit approval and program rules.
