Shopping for a home in Seattle or on the Eastside and hearing the word “jumbo”? You are not alone. In King County, many well-qualified buyers cross into jumbo territory because local prices outpace national norms. This guide breaks down what a jumbo loan is, how limits work, what lenders expect, and how to stay competitive in our market. Let’s dive in.
Conforming vs. jumbo basics
A conforming mortgage is one that meets Fannie Mae and Freddie Mac standards, including the maximum loan amount for your county. A jumbo mortgage is any loan amount above your county’s conforming limit, which means it is funded and underwritten by private lenders or held in portfolio.
The Federal Housing Finance Agency sets baseline conforming limits each year and publishes county-specific limits. These limits change annually, so a loan that is conforming one year could be jumbo the next. To classify your loan amount, check the current King County number using the FHFA’s county lookup on the FHFA conforming loan limits page.
Why jumbos are common in Seattle and the Eastside
Home values across Seattle, Bellevue, Redmond, Kirkland, and nearby communities are often well above the national median. That means typical loan sizes for move-up and luxury homes can exceed the conforming limit.
Neighborhoods with waterfront properties, view homes, or proximity to major employment centers see frequent jumbo financing. Competitive offer situations are common in upper price tiers, and you may encounter buyers with large down payments or cash.
What to expect with a Seattle jumbo mortgage
Documentation and underwriting
Expect full documentation. Lenders will verify income, assets, employment, and liabilities with pay stubs, W-2s, tax returns, and bank statements. Self-employed buyers typically need two years of returns and may be asked for year-to-date profit and loss statements. If you earn bonuses or stock/RSU income, plan for extra verification. Many jumbo programs also require documented reserves after closing.
Credit score and DTI
Strong credit is key. Many lenders look for a 700+ score, and 720+ can help with pricing. Debt-to-income limits are often tighter than conforming, with many lenders targeting 43 to 45 percent. Exceptions exist when you have compensating factors like substantial reserves or larger down payments.
Down payment and loan-to-value
For a primary residence, jumbo down payments commonly range from 10 to 20 percent depending on your profile and product. Second homes and investment properties usually require larger down payments, often 20 to 30 percent or more. Jumbos do not use private mortgage insurance, so lenders manage risk with pricing, reserves, or higher down payment requirements.
Reserves and liquidity
Plan to show healthy cash reserves. Many jumbo programs ask for 6 to 12 months of mortgage payments in reserves, and higher balances or higher loan-to-value scenarios may require more. Lenders will verify the source of funds, including the sale of another property, liquid investments, or eligible gift funds with proper documentation.
Appraisals and property reviews
Jumbo loans require full appraisals and careful review of property type, condition, and comparable sales. Unique homes or luxury features may require specialty valuation and additional time. Some properties with unusual characteristics may need a portfolio lender with flexible guidelines.
Rates and pricing
Jumbo rates often track Treasury yields and can be close to conforming rates for well-qualified borrowers. The spread changes with market conditions and lender appetite and can widen with higher LTVs, lower credit scores, or complex income. For an overview of jumbo mechanics and borrower expectations, review the CFPB’s guide on jumbo mortgages, then compare live quotes with local lenders.

How to stay competitive with jumbo financing
Get a full pre-approval
Request a full written pre-approval from a lender experienced with jumbo files. That means your income, assets, credit, and reserves are reviewed in advance. Organize tax returns, pay stubs, bank and investment statements, and employment verifications so underwriting can move fast once you are mutual.
Use the strongest product for your offer
If you can structure your offer to fit within the county’s conforming or high-balance limit, you may gain speed and pricing advantages. If a jumbo is necessary, consider a portfolio lender or a local credit union known for quick decisions and reliable closings.
Manage appraisal and financing risk
Shorten or streamline contingencies only when it fits your financial comfort. Some buyers include appraisal gap coverage to signal strength if the valuation comes in low. Larger earnest money, faster timelines, and verified reserves also reassure sellers that you can close.
Show liquidity and stability
Ask your lender to note verified reserves in your pre-approval letter. Demonstrating ready funds helps sellers trust your ability to handle minor appraisal variances or rate moves without delaying closing.
Consider bridge tools carefully
Bridge loans and HELOCs can free up down payment funds before your current home sells. These tools come with higher costs and moving parts, so align them early with your jumbo lender. The right plan can help you write a cleaner, more competitive offer.
Work with local experts
Choose a lender who knows King County’s appraisal landscape and timelines. Local processors, appraisers, and underwriters can help you clear conditions smoothly, especially with unique or higher-end properties.
How to check your loan size and next steps
- Confirm the current King County conforming limit on the FHFA conforming loan limits page, then compare it to your target loan amount.
- Gather documents now. Two years of tax returns, recent pay stubs, W-2s or 1099s, bank and investment statements, and any equity or gift documentation will speed pre-approval.
- Request multiple quotes. Portfolio lenders, credit unions, and brokers can price jumbo loans differently. Compare terms, rates, points, and reserve requirements.
- Align your financing with your offer strategy. Decide upfront whether you will use appraisal gap coverage, adjust your down payment, or consider bridge tools.
