Can I Qualify for a Mortgage Using an ITIN Instead of a Social Security Number as a Non-Citizen?
Yes, in many cases. Fannie Mae accepts either a valid Social Security number or an Individual Taxpayer Identification Number (ITIN) for each borrower. Separately, a non-citizen generally has to be a lawful permanent or non-permanent resident for a standard loan. If you can't document that, specialized ITIN loan programs exist, usually at a higher rate.
Last updated September 29, 2026What is an ITIN, and how does it work on an application?
The IRS issues ITINs to people who need to file U.S. taxes but can't get a Social Security number. On a mortgage application it fills the same slot: the lender uses it to verify your identity, pull credit and report to the IRS. Fannie Mae's guidelines require each borrower to have a valid Social Security number or ITIN, so either one meets that requirement.
Do I need to show lawful status?
For a standard loan sold to Fannie Mae, generally yes. Fannie Mae buys loans to non-citizens who are lawful permanent or non-permanent residents, and the lender has to confirm the borrower is legally present, using documents it considers appropriate, like a green card, visa or work authorization. An ITIN on its own doesn't show residency status.
What if I can't document lawful status?
It depends on your situation:
- You have an ITIN and can document lawful residency: you may qualify for a standard loan using the ITIN.
- You have an ITIN but can't document lawful status: standard agency loans generally aren't available. Many lenders offer non-QM ITIN loan programs built for this, with more manual underwriting and typically higher rates, depending on the program, your credit and your down payment.
- You're a foreign national with no U.S. credit history: that's a separate category, and foreign national programs have their own documentation and down payment rules.
Programs vary a lot, so compare more than one.
Will large bank deposits cause problems?
They can slow things down. When a deposit doesn't clearly match your usual income, lenders commonly ask where it came from before counting it. That's routine for every borrower under Fannie Mae's rules, not something aimed at ITIN applicants. Keep paperwork for any large deposit, like a gift letter or a record of something you sold, so you can answer quickly.
