Down Payment Assistance in Seattle & King County (2026)

Down Payment Assistance in Seattle & King County (2026): What Every Buyer Should Know

Saving for a down payment in Seattle is genuinely hard. The median home price in King County sits above $800,000 in 2026, which means even a 5% down payment requires $40,000 or more in cash — before closing costs. For many buyers, the mortgage payment is actually more affordable than the rent they're already paying. The barrier isn't the monthly payment. It's that first big check at the closing table.

The good news: Washington State and King County have some of the most robust down payment assistance (DPA) programs in the country, and most buyers don't know they exist. I've spent 20 years helping Seattle-area buyers unlock these programs, and I still see clients walk away from thousands of dollars because nobody told them to ask.

Here's what's available in 2026 and who qualifies.

Washington State Housing Finance Commission (WSHFC) Programs

The WSHFC is the backbone of affordable homeownership in Washington and your first stop for DPA.

Home Advantage DPA

This is the most widely used program in the state. When you use a WSHFC-approved lender for your first mortgage, you become eligible for a second mortgage of up to 4% of the loan amount to cover down payment and/or closing costs. In 2026, there are no purchase price limits, but income limits apply — generally up to $180,000 for most King County households. The second mortgage is at 0% interest and deferred for the life of the loan, meaning you don't make monthly payments on it. It's repaid when you sell, refinance, or pay off the home.

House Key Opportunity Program

This is a below-market-rate first mortgage combined with DPA for buyers at or below 80% of Area Median Income (AMI). For a family of four in King County in 2026, 80% AMI is approximately $99,200. House Key is a true affordability program — it's not just down payment help but also a subsidized interest rate. Inventory of these funds is limited and moves quickly, so early application matters.

HomeChoice Program

For buyers with a disability or who have a household member with a disability, HomeChoice offers up to $15,000 in down payment assistance as a second mortgage at 1% interest. It's one of the most underutilized programs I encounter.

All WSHFC programs require a WSHFC-approved homebuyer education course — typically a one-day class available online. If you're exploring any of these programs, complete that course early. It counts toward multiple programs simultaneously.

King County Down Payment Assistance Program

King County operates its own DPA program specifically targeted at buyers purchasing in unincorporated King County and participating cities. In 2026, this program offers deferred-payment loans up to $100,000 — one of the highest amounts in the state — for buyers at or below 80% AMI. This is a soft second mortgage: no monthly payments, and it's forgiven after a specified period if you remain owner-occupant.

The large loan amount makes this program a genuine game-changer for first-generation buyers and those with thin savings. A $100,000 DPA loan effectively eliminates the down payment requirement on a home under $500,000.

Seattle Office of Housing Programs

If you're buying specifically within Seattle city limits, the Seattle Office of Housing administers its own loan programs in partnership with nonprofit lenders. These are income-restricted (typically 80% AMI and below) and designed for buyers who might not qualify for conventional financing without assistance. Loan amounts vary by program cycle and available funding. These programs are worth investigating directly if you're targeting neighborhoods like Rainier Valley, Beacon Hill, or South Seattle.

How These Programs Stack — The DPA Combination Strategy

Here's something most buyers don't realize: you can often layer multiple programs. A qualified buyer might combine a WSHFC Home Advantage first mortgage with a Home Advantage 4% DPA second, plus an employer assistance grant (Amazon, Microsoft, and some hospital systems offer housing benefits). I've helped buyers walk into closing with less than $5,000 out of pocket on a $450,000 home using this approach.

Stacking requires coordination — not all programs allow combinations, and the order of liens matters. This is where working with a local loan officer who knows the Washington DPA landscape pays for itself.

Income Limits & Eligibility Basics for 2026

Program eligibility varies, but here are common thresholds to check yourself against:

• 80% AMI (King County, 2026): ~$86,400 for a 2-person household; ~$99,200 for a 4-person household
• 100% AMI: ~$108,000 (2-person); ~$124,000 (4-person)
• Home Advantage income cap: Up to ~$180,000 for most household sizes — this covers many dual-income professional households

Most programs define first-time homebuyer as not having owned a primary residence in the past three years — so if you owned a home, sold it during the divorce, and haven't bought since, you may qualify again. This comes up often in divorce mortgage situations I handle.

What About Tech Employees & Higher Incomes?

If you work at Amazon, Microsoft, or another major tech employer and your W-2 is above the DPA income thresholds, you're likely not eligible for most of these programs — but you have other tools. RSU income, stock option proceeds, and employer stock purchase plan distributions can all be used strategically to fund your down payment and qualify for a larger conventional or jumbo loan. I've written specifically about mortgage strategies for tech employees in Seattle if that's your situation.

Doctor Loans: A Different Kind of Down Payment Solution

For physicians, dentists, and other medical professionals in the Seattle area, DPA programs often conflict with physician loan structures. Physician loans are designed precisely to solve the down payment problem for high-income, high-debt borrowers — offering 0–5% down without PMI and without income caps. If you're a resident or early-career attending, physician mortgage loans are almost always a better fit than state DPA programs.

How to Actually Apply

1. Get pre-approved first. DPA programs require a qualified first mortgage — you need to know your loan amount before applying for assistance.
2. Complete homebuyer education. WSHFC requires it. Do it early so it doesn't delay your closing timeline.
3. Work with a WSHFC-approved lender. Not all lenders are approved to originate WSHFC loans. As an approved Washington State lender, I can originate Home Advantage, House Key, and help you apply for county and city programs simultaneously.
4. Act fast. King County and Seattle program funds are allocated on a first-come, first-served basis and routinely run out mid-year. Spring and early summer are high-competition periods.

Bottom Line

Seattle is expensive, but it's not unreachable — especially if you know which programs to combine. Down payment assistance in King County in 2026 ranges from modest 4% second mortgages to six-figure deferred loans, and most buyers leave this money on the table simply because they didn't ask.
