10% Down Jumbo Home Loans

10% down jumbo home loans let qualified Washington buyers finance a loan above $1,063,750, the 2026 conforming limit in King and Snohomish counties, while putting down 10% instead of 20%. They typically require stronger credit, lower debt, and larger cash reserves, and some programs add mortgage insurance.

I have spent more than 25 years closing loans around Puget Sound, and this is one of the most useful programs I offer Eastside and Seattle buyers who have strong income but do not want to drain their savings or sell stock to reach 20%. Here is how it works and when it makes sense.

How a 10% Down Jumbo Loan Works

With 10% down, you finance 90% of the price, which lenders call a 90% loan-to-value (LTV) loan. Because the loan is above the conforming limit, Fannie Mae and Freddie Mac do not buy it. The lender keeps it or sells it to a private investor, so each program sets its own rules.

That has three practical effects. Requirements are stricter than at 20% down, many programs cap the loan amount lower at 90% LTV than they do at 80%, and some programs charge mortgage insurance while others build the extra risk into pricing instead. Two lenders can give the same buyer very different answers, which is why comparing programs matters more here than almost anywhere else.

When Does 10% Down Put You in Jumbo Territory?

The conforming limit applies to the loan amount, not the price. So the same home can need a jumbo loan at 10% down and a conforming loan at 20% down. Here is how that plays out in King and Snohomish counties for 2026 (illustrative purchase prices):

The middle zone is the one to watch. For a one-unit home priced between about $1,182,000 and $1,330,000, 10% down means a jumbo loan and 20% down means a conforming one. If you are shopping in that range, it is worth running both before you decide. These examples are illustrative only, not a loan offer, and your actual terms depend on a full loan estimate.

Requirements for 10% Down Jumbo Loans in Washington

Every program writes its own rules, so treat these as typical ranges rather than fixed requirements:

• Credit score. Often 700 or higher, and many 90% programs look for 720 to 740 or more.
• Debt-to-income ratio. Commonly capped around 43%, sometimes lower at 90% LTV.
• Cash reserves. Usually more than at 20% down. Plan on showing many months of full housing payments in savings or investments after closing, often 12 months or more on larger loans.
• Loan amount. Many programs cap the loan lower at 10% down than at 20% down, so very large purchases may need more down.
• Occupancy and property. 10% down is generally for a primary residence. Second homes, investment properties, and some condos typically need more down.
• Documentation. Full income and asset documentation, usually with two years of history for bonus, commission, or RSU income.

Mortgage Insurance on a 10% Down Jumbo Loan

Some 10% down jumbo programs require private mortgage insurance, and others skip it and price the extra risk into the loan instead. Neither is automatically better. The right comparison is the total cost over the years you expect to keep the loan, which I lay out on actual Loan Estimates, side by side, for the same loan amount and lock period.

10% Down vs 20% Down on a Jumbo Loan

Putting down less keeps more of your money working for you, but it costs something. Here is the trade-off in plain terms:

• 10% down keeps more cash. On a $1,500,000 purchase, that is $150,000 you do not have to bring to closing, which can stay invested, cover a remodel, or sit in reserves.
• 20% down usually costs less over time. A smaller loan, more program choices, and no mortgage insurance typically mean a lower monthly payment.
• 20% down can avoid jumbo entirely in the middle price zone shown above.

I walk through the numbers in my guides to 10% vs 20% down on a jumbo loan and 20% down jumbo loans.

Alternatives to a 10% Down Jumbo Loan

• First and second mortgage. A conforming first mortgage at 80% plus a second mortgage or home equity line for 10% can sometimes beat a single 90% jumbo loan. It works best when the first mortgage stays at or under $1,063,750.
• Conforming with less than 20% down. If your loan fits under $1,063,750, a conforming loan with mortgage insurance may be simpler than a jumbo program.
• Gift funds. Many jumbo programs allow family gifts toward the down payment, though some want part of the down payment from your own funds.

10% Down Jumbo Loans for Tech Professionals

This program fits a common Eastside situation: a high household income, a large balance in company stock, and no interest in selling shares and triggering taxes just to reach 20% down. RSU income can usually count toward qualifying once there is a reliable vesting history, and vested shares can often count toward reserves, typically at a discount to their market value.

How much counts depends on how long you have received RSUs, whether the grants continue, and the program. A first-year hire with a large sign-on grant is treated very differently from someone with several years of steady refreshers. This is not tax advice, so talk to a tax professional before you sell stock to fund a purchase.

How to Get a 10% Down Jumbo Loan

1. Get fully pre-approved. Jumbo underwriting is less automated, so a pre-approval backed by real documents matters.
2. Gather two months of statements for every account you will use for the down payment or reserves, plus your RSU vesting schedules.
3. Compare programs. We look at 90% jumbo options, a first and second mortgage, and 20% down side by side.
4. Make your offer. My team closes in 9 business days, which carries real weight when a seller is comparing offers.
5. Appraisal, underwriting, and closing. Expect a detailed review of income, assets, and the property before you sign.
