Foreign National and ITIN Mortgages in Seattle: Buying Without an SSN

A foreign national mortgage in Seattle lets a buyer without a Social Security number finance a home through portfolio lending, typically with 25 to 30 percent down and asset-based qualifying. Visa holders who already hold U.S. credit usually qualify for standard agency financing instead, subject to qualification.

A research scientist walked into my Eastlake office last year with an offer letter from one of the immunotherapy labs on Dexter Avenue, a lease she wanted out of, and a question she had already asked two national call centers. Could she buy a condo without a Social Security number. Both had told her no. Both were wrong, or at least incomplete.

She had an Employment Authorization Document, eighteen months of U.S. credit, and a pending green card. She closed on a one-bedroom near Lake Union Park on a standard conventional loan. Nothing exotic about it. The problem was never her file. The problem was that nobody had asked the right three questions.

South Lake Union sits at the center of this conversation in a way few Seattle neighborhoods do. Amazon's headquarters campus, Fred Hutchinson Cancer Center on Fairview Avenue North, the Allen Institute at Westlake and Mercer, UW Medicine's research buildings, and a dense cluster of younger immuno-oncology companies like Sana Biotechnology and Umoja Biopharma all recruit internationally. A meaningful share of the people walking to work through that corridor are on an H-1B, an L-1, an O-1, a TN, or an EAD.

One note before we start. I am a lender, not an immigration attorney. Nothing here is legal or immigration advice, and visa questions belong with your attorney. Every figure below is illustrative and dated July 2026. Your actual terms come out of a full loan estimate, subject to qualification and subject to credit approval.

What a Foreign National Mortgage in Seattle Actually Means

The phrase gets used loosely, and that is where most of the confusion starts. Lenders use "foreign national" narrowly. It describes a buyer with no U.S. residency status, no Social Security number, and no U.S. credit history, who is buying property here from abroad or on a short-term visa.

That is a much smaller group than people assume. For example, a software engineer on an H-1B who has lived in Seattle for three years, paid U.S. taxes, and carries a U.S. credit card is not a foreign national in the lending sense. She is a non-permanent resident alien, and as a result Fannie Mae and Freddie Mac treat her essentially the same as a citizen.

So the first thing I do on these calls is sort you into the right bucket. Getting that wrong costs people either money or a house. Buyers who belong on the agency path get quoted portfolio terms they never needed. Buyers who genuinely need portfolio money spend six weeks discovering agency will not take them.

Three Paths to a Foreign National Mortgage in Seattle

In practice, almost every file I see sorts into one of three lanes. The lane is set by your documentation, not by your nationality.

All three are real. However, only the first one runs through the ordinary agency machinery, and that matters more than any single term on the sheet. Agency guidelines are published, so every lender works from the same book. Portfolio guidelines are written by whoever holds the loan, which is why quotes vary so widely from one shop to the next.

The Visa Holder Path: H-1B, L-1, O-1, and TN Buyers

This is where most South Lake Union and U District buyers land, and it is the least complicated of the three. Fannie Mae and Freddie Mac allow non-permanent resident borrowers on the same terms as citizens when two conditions hold. You have a valid Social Security number, and your legal right to work here shows evidence of continuance.

Continuance is the piece people trip on. Underwriting is not asking whether you will live here forever. It is looking for a reasonable expectation that your authorization will be renewed, which is usually satisfied by an unexpired visa, an I-797 approval notice, an EAD card, or a letter from your employer confirming ongoing sponsorship. However, an expiration date inside the next several months does need a paper trail behind it. On its own it is not a problem.

The other half of the conversation is income. Tech and biotech offers in this corridor lean heavily on restricted stock, and the rules there are strict enough to deserve their own guide. If your compensation includes equity, read the piece on documenting RSU and bonus income for a Seattle mortgage before you assume your total comp is your qualifying number. It generally is not.

Thin credit is the other common wrinkle for recent arrivals. Someone who landed from Bengaluru or Zurich nine months ago may have a strong salary and almost no U.S. credit depth. There are documented workarounds using alternative trade lines like rent, utilities, and insurance. They take time to assemble, which is the argument for starting early rather than the week you find a listing.

True Foreign National Loans in Seattle: Portfolio Money Without U.S. Credit

When there is no Social Security number and no U.S. credit file, agency financing is off the table. That is a guideline, not a judgment, and it is where portfolio lending picks up.

A portfolio lender keeps the loan on its own books rather than selling it to Fannie or Freddie, so it can write its own rules. Those rules generally trade flexibility for cushion. In practice, down payments commonly run 25 to 30 percent. Qualifying leans on verified assets and, where available, a credit reference letter from your home-country bank rather than a U.S. score. Reserves after closing tend to run higher than an agency file would ask.

Two things deserve plain statement here. First, portfolio loans do not carry the same terms or protections as agency loans, and some carry prepayment penalties. Second, every one of these files is underwritten case by case, so nothing is standard until it is in writing.

Movement's own menu covers the agency path for visa holders directly. For true foreign national and ITIN files, I will tell you honestly at the first call whether we can place it in house or whether you are better served by a portfolio lender who writes these every week. Sending you down a path that ends in a decline six weeks later helps nobody. If the qualifying question is really about assets rather than status, my guide to asset depletion loans in Seattle covers how lenders convert balances into monthly qualifying income.

ITIN Home Loans in Seattle: Buying With a Tax ID Instead of an SSN

An Individual Taxpayer Identification Number is issued by the IRS to people who have federal tax obligations but are not eligible for a Social Security number. You can read the eligibility basics on the IRS ITIN page. It is a tax identifier, not a work permit and not an immigration status.

ITIN mortgage products exist, but they live in a narrow corner of the market. Expect a larger down payment than an agency loan, full documentation of income and time in the country, and a lender who has done these before. In addition, some programs want two years of filed returns using the ITIN. Others will look at bank deposits instead, which is closer to how a bank statement loan in Seattle reads self-employed cash flow.

These borrowers show up less often in the tech and biotech profile around South Lake Union than they do elsewhere in the county, but they are here, and the product is real. What sinks these files is almost never the borrower. It is a listing agent or lender who has never seen one and assumes it cannot be done.

What Documents a Foreign National Mortgage in Seattle Requires

The document list is the honest difference between these paths. Nothing on it is unusual on its own. What is unusual is how long some of it takes to gather from another country.

In practice, the line that catches people is the last two rows. Moving money across borders, seasoning it, and producing a clean paper trail for every transfer can take longer than the escrow period allows. Start that step first, not last.

Why Condo Warrantability Complicates a Foreign National Mortgage in Seattle

South Lake Union is effectively a condo market. Outside a handful of legacy houses and townhomes near Cascade and along Pontius, the inventory is mid-rise and high-rise. Buildings like 2200 Westlake above the Whole Foods, Onyx, Veer Lofts, and the newer towers are where these purchases actually happen, and the building underwrites alongside the borrower.

Fannie Mae publishes project standards, and a building fails them for reasons that have nothing to do with you. Pending litigation against the homeowners association. Commercial space above 35 percent of total floor area, which is common in mixed-use towers here. A single owner holding more than 10 percent of the units. Reserve contributions below the required share of the annual budget.

When a building fails, conventional financing is off the table even for a citizen with perfect credit. As a result, stacking that on top of a portfolio borrower profile gives you two case-by-case reviews at once, which is exactly the kind of file that needs to be sorted out before an offer goes in rather than after. My guide to condo and townhome financing in central Seattle covers the questionnaire and what to ask for.

One more piece of local math. Homeowners association dues in these buildings commonly run between 700 and 1,500 dollars a month depending on amenities and the scope of the master insurance policy. That figure goes straight into your debt-to-income ratio, and it moves qualifying more than most buyers expect. Bake it in at pre-approval rather than discovering it during underwriting.

How Early Should You Start a Foreign National Mortgage in Seattle?

Earlier than you think, and for a specific reason. On a standard W-2 file, pre-approval can come together quickly. On these files the bottleneck is documents that live in other countries and other institutions.

Here is the sequence I would ask for if you were sitting across the desk from me. Start the work authorization paperwork first, because the I-797 or EAD copy is the gate. Then open or fund the U.S. account you will close from, so the money has time to season, which just means sitting in one place long enough for a lender to verify where it came from. Then request the foreign credit report or bank reference letters, which routinely take a few weeks. Translations and currency conversions go last, once you know which documents actually matter.

In addition, price point deserves a look at the same time. Median condo sale prices in South Lake Union generally sit in the mid seven hundreds to low eight hundreds, which keeps most buyers inside standard conforming limits. However, view and penthouse units in the newer towers can cross into higher territory. The 2026 one-unit conforming limit in King County is 1,063,750 dollars, well above the 832,750 dollar national baseline, and you can confirm the current figures on the FHFA conforming loan limit map. If your loan amount is heading past that ceiling, the guide on high-balance versus jumbo in King County explains what changes.

Where This Guide Fits in the Central Seattle Series

This piece is the sorting hat. Each of these goes deeper on one part of the picture.

• Your neighborhood. The South Lake Union home loans hub covers the corridor, its condo pricing tiers, and the employers behind most of these files.
• Equity compensation. The RSU and bonus income guide shows how restricted stock qualifies and what history underwriting wants to see.
• The building itself. My condo and townhome financing guide walks through warrantability and the HOA questionnaire.
• Qualifying on assets. The asset depletion guide explains how balances become monthly qualifying income.
• Above the limit. The high-balance versus jumbo guide maps the King County ceiling and what sits on each side.

When you are ready to see real numbers on your own scenario, you can start an application or call me first and we will talk it through.
