Jumbo Loan vs Conforming Loan: A 2026 Guide for Seattle Buyers

This article was originally published on May 26, 2021. It was updated on October 15, 2026.

“How much can I borrow?”

It’s the first question most Seattle home buyers ask their lender, and for good reason.

The median sale price in Seattle and King County was $850,000 in September 2026, and with interest rates hovering above 7%, that’s a lot of money on the line for the average Seattle family.

In a housing market like this, you’ll want to know your limits before you fall head over heels for a house.

That’s where many buyers trip up.

They find a home they love, see that it’s priced above the loan limit, and figure it’s off the table. So they shop for less. Or they hold off and keep saving for that ever-elusive 20% down.

But there’s one critical fact that most buyers overlook once the search for their forever home takes off.

The loan limit only caps your loan; it doesn’t cap your home.

Stay under the limit, and you’ve got a conforming loan. Go over it, and you’ll use a jumbo loan, which many buyers can still get with 5% to 10% down. It’s your down payment that decides which side of the line you’re on.

In this article, we’ll break down the ins and outs behind jumbo loans and conforming loans, so you can plan the right loan for the Seattle home you want.

What Happens When Seattle Buyers Misread the Loan Limits

Meet Maya and Ben.

They’re a couple from Seattle, and just like most young couples in the area, they’re on the hunt for their first home.

For the past three years, they’ve lived in Ballard and have come to know the neighborhood by heart. They’re regulars at the Sunday farmers market and have enjoyed dozens of picnics in Golden Gardens Park.

So when they started looking for a home of their own, leaving wasn’t even an option.

After months of tours, they find it. It’s an older Craftsman a few blocks off Market Street, with a covered porch and a backyard big enough for a garden. Plus, the monthly mortgage payments fit their budget.

Then they look closer at the numbers.

The purchase price sits just over the loan limit, and they figure that puts it out of reach.

So they pass.

They decide to keep saving until they have 20% down, since they think a bigger loan needs a larger down payment.

A year later, they start touring again. And as market conditions shifted, homes like that Craftsman now cost more. The money they’ve worked so hard to save covers a smaller share of the price. And for that whole year, their rent went to a landlord instead of building equity in a home of their own.

If this story sounds familiar, that’s because it’s a mistake plenty of Seattle buyers make each year.

The hard part is that Maya and Ben never needed to wait. The loan limit only decides which type of loan they use. It doesn’t decide which homes they can buy. With the right down payment, the loan on that Craftsman could have stayed under the limit.

And if it went over, many jumbo loans still work with 5% to 10% down. Instead of starting their search over, they could have been a year into owning their home and building equity.

In the next section, we’ll share what makes a loan conforming or jumbo, and why going over the limit doesn’t put a home out of reach.

Why Going Over the Conforming Loan Limit Doesn’t Put a Home Out of Reach

Before you rule out a home because of its price, it helps to know what the loan limit measures.

To be clear, it measures your loan amount. The home’s price is a separate number, and your down payment is what connects the two.

What Makes a Conforming Mortgage in King County

Conventional conforming loans are standard home loans that stay at or under a set amount. Conforming loan limits are set by the Federal Housing Finance Agency (FHFA) and are updated each year.

For most of the country, the 2026 baseline conforming loan limit is $832,750. In high-cost areas like King County, which includes Seattle, it’s $1,063,750 for a single-family home. Pierce and Snohomish counties share that higher limit because the Seattle area is one of the country’s most expensive housing markets.

So a loan that would exceed conventional loan limits doesn’t necessarily stop you from buying a home.

It simply means you’ll use a different type of loan, known as a non-conforming loan.

How and When Your Loan Becomes a Jumbo Mortgage Loan

In King County, a jumbo loan exceeds $1,063,750. “Jumbo” only describes the loan size. It doesn’t mean the loan carries more risk or is harder to get.

In fact, for most buyers, there’s no real cap on how big a jumbo loan can be. That’s because loans don’t start to work differently until they reach the $5 million to $10 million range.

Some jumbo loans require a more significant down payment.

But truthfully, many still work with smaller down payments of 5% to 10%.

A piggyback loan can help, too. It’s a second, smaller loan you take out at the same time as your main one. It covers part of your down payment, so you bring less cash to closing. It can also help you skip mortgage insurance, which is the extra monthly fee lenders usually charge when you put less than 20% down.

How 5% Down Can Keep You Under the Limit

Say you find a Seattle home listed at $1,100,000. The price is above the $1,063,750 loan limit, so it’s easy to assume you’d need a jumbo loan.

Here’s what the numbers look like with a lower down payment of 5%:

• Home price: $1,100,000
• Down payment (5%): $55,000
• Loan amount: $1,045,000

That’s a 95% loan-to-value ratio, meaning the loan covers 95% of the price.

The loan lands $18,750 under the limit. That’s a conforming loan. No jumbo loan needed.

With 5% down, a Seattle home can cost up to about $1,119,000 and still keep the loan under the limit. With 10% down, that number climbs to about $1.18 million.

You Probably Need Less Than 20% Down

The 20% rule for a conventional mortgage keeps a lot of buyers waiting. But most buyers don’t put that much down.

The National Association of Realtors’ 2025 buyer report found the typical buyer put 19% down. First-time buyers put down 10%, and repeat buyers put down 23%. Repeat buyers often have equity from a home they already owned, which helps explain the gap.

Some loan options ask for even less:

• FHA loans (backed by the Federal Housing Administration, a government agency): As little as 3.5% down with a minimum credit score of 580, which makes FHA a good fit for buyers with lower credit scores. In King County, the FHA limit matches the conforming limit.
• VA loans: Zero down for eligible service members, veterans, and surviving spouses, with no private mortgage insurance.
• USDA loans: Zero down for low- and moderate-income buyers in eligible rural areas. Seattle itself doesn’t qualify, but some areas outside the city may.

Local programs can lower the amount even more. The Washington State Housing Finance Commission offers down payment assistance loans to low- and moderate-income buyers who use its home loan programs. Buyers inside Seattle city limits who earn 80% or less of the area median income can also get help through the Seattle Office of Housing and its nonprofit partners. Each program has its own income limits, so it’s worth checking early.

How Seattle’s Mortgage Broker Helps You Choose the Right Mortgage Loan

Unlike many lenders, Seattle’s Mortgage Broker is a full-service mortgage consulting firm with decades of experience helping Seattle home buyers choose between jumbo and conforming loans before they start making offers.

Our process starts with your down payment.

If a home sits just above the $1,063,750 limit, we’ll check whether 5% or 10% down keeps your loan conforming. If going over makes more sense, we’ll set you up with a jumbo loan. As we covered earlier, many jumbo loans still work with 5% to 10% down.

We also review your financial profile, starting with your debt-to-income ratio. That’s the share of your monthly income that already goes to debt payments. It affects how much a lender will let you borrow, so we check it before you start house hunting.

Then we work with your realtor on an offer that stands out without leaving you overexposed or overpaying. Plus, we regularly close loans in under two weeks, which lets our buyers compete with, and win against, all-cash offers.

In fact, on average, our clients make 70% fewer offers than the industry average, meaning they spend less time touring and more time building equity in their forever home.

Know Your Numbers Before You Start House Hunting

If there’s one idea you should take away from this article, it’s that the loan limit only decides what type of loan you’ll use.

Your down payment and your plan are what decide which homes are within reach.

If a home you love is over the limit, that’s okay.

A jumbo loan can still work, and more often than not, you likely need less than the 20% that’s often cited for conventional loans.

The best time to figure this out is before you fall head over heels for a house. That way you can search for your dream home knowing what fits your budget, and when the right home comes along, you’ll be ready to make an offer instead of letting it slip away.

Even if you’re not ready to buy just yet, it’s worth booking a call with us. That way we can help you see your numbers in advance, and at your not left with unanswered questions when the right home hits the market.
