Program overview
House Key Opportunity is Washington's statewide first mortgage with deferred down payment assistance attached. It pairs with a set of separate local seconds — Home Advantage, House Key Plus, and county-specific funds — which is why Washington buyers frequently stack two layers of help. Seattle and King County buyers in particular have access to some of the largest local assistance in the western US.
Best for: Washington first-time buyers, especially in King, Pierce, Snohomish, Spokane, and Clark counties.
Who qualifies
- First-time buyer rule: You generally cannot have owned a primary residence in the last three years.
- Credit score: A 620 credit score is the general floor; 640 or higher opens more first mortgage options.
- Income limits: Washington sets income limits by county and household size, and King County limits are substantially higher than rural county limits.
- Occupancy: Primary residence only, and you must complete a WSHFC homebuyer seminar.
- Eligible loans: FHA, VA, USDA, Conventional
- Homebuyer education: Required before closing. Start it early — certificates take days to issue.
Do you pay it back?
A deferred second at a low fixed rate; principal and accrued interest are due when you sell, refinance, or pay off the first mortgage.
