Yes, Seattle-area buyers can get a mortgage loan over $1 million. But a loan above that amount is not automatically a jumbo loan. Whether it falls into a conforming or jumbo category depends on the county loan limit where the property is located, along with other transaction details.
If you’re comparing large-loan options in the Seattle area, the key is to determine which loan category your target amount falls into and then prepare for the credit, down payment, income, and debt review that comes with it.
When it comes to their size, mortgage loans can be categorized as either conforming or jumbo.
In 2026, the conforming loan limit for King County is $1,063,750 for a one-unit property. Loan limits can vary by county, so borrowers in the Seattle area should compare their loan amount to the applicable county limit to determine whether they need a conforming or jumbo mortgage.
A simple way to think about it is:
FHFA states that the 2026 conforming loan limit values have been set under the HERA formula, and that the ceiling loan limit for one-unit properties will be $1,249,125, which is 150 percent of $832,750. Even so, Seattle-area buyers should verify the current limit for the specific county and property type involved, and confirm lender guidelines before applying.
Jumbo (or non-conforming) home loans represent a higher risk to the lender, and for two reasons. First of all, there’s a larger amount of money being borrowed. Secondly, these loans cannot be sold to the government-sponsored mortgage buyers Freddie Mac and Fannie Mae.
Now let’s shift gears and talk about some of the requirements for obtaining a mortgage loan in excess of $1 million.
All borrowers can benefit from having good credit. A good credit history and score can help you qualify for a mortgage loan with a good interest rate. But having good credit is even more important when it comes to jumbo mortgage loans.
If you want to borrow more than $1 million for a home purchase in the Seattle area, you’ll need to have a good credit score and history. This shows that you have borrowed and repaid money successfully in the past, an important quality for someone seeking a mortgage loan over $1 million.
There is no specific credit score threshold that applies to all borrowers across the board. Credit scores are part of a broader qualification process. But generally speaking, a higher score will increase your chances of qualifying for a mortgage loan over $1 million in the Seattle area. While a lower score could have the opposite effect.
Every jumbo lending scenario is different, because every borrower is different. But in general, home buyers who are seeking a jumbo mortgage loan over $1 million usually have to put more money down, compared to someone with a smaller loan.
This relates back to the risk factor we discussed earlier. Home loans that exceed $1 million represent a higher risk to the bank or lender that offers them. As a result, borrowers typically have to make a larger down payment on these loans.
In contrast, Seattle-area home buyers who use conforming mortgage loans can often put down as little as 3%. But the down payment requirement is usually higher for a jumbo product.
Home buyers seeking a mortgage loan over $1 million in the Seattle area must also be able to document their income. This is for obvious reasons. In short, you’ll need to have enough income to manage the monthly payments for the amount you’re trying to borrow.
Mortgage lenders often use the debt-to-income (DTI) ratio to assess these things. As you might have guessed, this is a comparison between the amount of money a person earns through income, and the amount they spend on all recurring debts.
When borrowing more than $1 million, home buyers typically need to keep their total DTI ratio at or below the mid-40% range. That number is not set in stone, but it does represent a common threshold within the lending industry. In some cases, exceptions can be made to allow for a higher debt ratio.
This qualification process serves everyone’s best interests. As a borrower, the last thing you want to do is take on too much mortgage debt in relation to your income. To help guard against this, lenders use the DTI ratio and other tools to qualify mortgage applicants.

No. In the Seattle area, a loan over $1 million may still be conforming if it falls within the applicable county limit for the property. If it exceeds that limit, it generally becomes a jumbo loan.
County loan limits help determine whether your loan is conforming or jumbo. Two buyers with similar loan amounts could end up in different categories if they are purchasing in different counties or different property types.
They may. Reserve expectations can vary based on the loan type, occupancy, overall borrower profile, and lender guidelines. This is one reason it helps to review your full scenario with a lender before applying.
Often, yes, if the income can be properly documented and meets lender requirements. For large-loan underwriting, the type, history, and consistency of income can all matter.
There is not one single jumbo loan limit for all Seattle-area buyers. Whether a loan is jumbo depends on the applicable county limit and the property type. In 2026, the conforming loan limit for King County is $1,063,750 for a one-unit property, and loans above the applicable limit generally require jumbo financing.
There is no single minimum score that applies to every borrower. In general, a higher credit score improves your chances of qualifying for a mortgage over $1 million, especially if the loan falls into the jumbo category.
It depends on the loan type and borrower profile, but buyers seeking a mortgage over $1 million usually need a larger down payment than someone using a smaller conforming loan. Jumbo loans often require more money down because they present more risk to the lender.
There is no universal income requirement because qualification depends on the full picture, including debt, credit, down payment, and the exact loan amount. Lenders typically look for sufficient documented income and a manageable debt-to-income ratio, often at or below the mid-40% range.
Potentially, yes, but the loan category and requirements can vary by occupancy type and lender guidelines. Occupancy is one of the transaction details lenders review along with loan amount, county limit, credit, income, debt, and reserves.
The monthly payment depends on factors such as the interest rate, loan term, down payment, taxes, insurance, and whether the loan is conforming or jumbo. A mortgage calculator or lender quote can provide a more accurate estimate for a specific Seattle-area scenario.
