Home financing in King County.

Home financing means borrowing money to purchase, refinance, or improve a home, then repaying that loan over time — usually 15 to 30 years — with interest. The most common product is a mortgage, but in King County you will also encounter home equity lines of credit (HELOCs), land contracts, down payment assistance loans, and bridge loans designed for investors flipping or renting properties.

King County is one of the most expensive housing markets in the United States. Median home prices in Seattle and surrounding cities like Bellevue, Renton, and Kent regularly exceed $700,000. That price level shapes everything: down payment requirements are larger in dollar terms, debt-to-income ratios are harder to hit on a modest income, and competition moves quickly.

This is exactly why the local intermediary layer — community lenders, CDFIs, and mission-driven credit unions — matters so much.

They understand the local market and often carry programs that mainstream national lenders do not advertise.

King County's economy is anchored by technology, healthcare, construction trades, maritime industries, and a large immigrant entrepreneurship sector. That means many residents earn income in ways that do not fit neatly on a W-2: gig work, sole proprietorships, rental income, subcontracting, or mixed sources.

**Solo contractors and self-employed workers:** You can qualify for a mortgage, but lenders will typically want two years of filed tax returns showing consistent income. If your write-offs bring your taxable income down significantly, a bank statement loan or a CDFI product may fit better than a conventional Fannie Mae loan.

**Immigrant and mixed-status households:** You do not need a Social Security Number to buy a home in Washington State.

Several lenders in King County accept Individual Taxpayer Identification Numbers (ITINs) in place of SSNs.

You will need a credit history (or a lender willing to build alternative credit from rent, utilities, and remittance records) and legal presence documentation.

**First-time buyers:** Washington State sets income and purchase price limits for its assistance programs. For King County, income limits are generally higher than statewide averages to reflect local costs — check the Washington State Housing Finance Commission (WSHFC) website for current figures, as they update annually.

**Small real estate investors:** If you are purchasing a duplex, triplex, or fourplex as a primary residence, you may still qualify for FHA or WSHFC programs. Pure investment properties require conventional or portfolio loans, and local credit unions and community banks are often the most flexible option here.

Having your documents ready before you approach a lender saves weeks of back-and-forth. Requirements vary by lender and loan type, but most King County lenders will ask for some combination of the following:

**Identity and residency:**

- Government-issued photo ID (passport, consular ID, state ID, or driver's license)

- ITIN letter (if no SSN) or Social Security card

- Visa, green card, or other immigration status documentation if applicable

**Income:**

- Last two years of federal tax returns (all schedules, including Schedule C for self-employed)

- Last two to three months of bank statements

- Profit-and-loss statement if self-employed (some lenders require a CPA to prepare this)

- 1099 forms or business income records

- Award letters for Social Security, disability, or pension income

**Assets:**

- Bank and investment account statements (last two to three months)

- Gift letter if any part of your down payment is a gift from family

- Documentation of any other assets (vehicle titles, retirement accounts)

**Property:**

- Signed purchase and sale agreement (once you are under contract)

- Homeowners insurance quote

- HOA documents if applicable

**Credit:**

- Lenders will pull your credit report directly, but you should review your own report first at AnnualCreditReport.com — it is free and does not affect your score.

- If you have no traditional credit history, gather 12–24 months of on-time payment records: rent receipts, utility bills, or phone bills.
