Can I buy a house with an ITIN instead of a Social Security number?
The full answer
An ITIN mortgage is a non-QM loan designed for borrowers who file U.S. taxes with an IRS-issued ITIN rather than an SSN. The government-backed programs (Fannie Mae, Freddie Mac, FHA, VA, USDA) all require a Social Security number, so ITIN loans come from lenders who hold the loans on their own books — community banks, credit unions serving immigrant communities, and non-QM portfolio lenders.
These programs typically require a larger down payment (often 15–25%), accept non-traditional credit (12 months of rent, utilities, and insurance payments) when you have no FICO score, and want a U.S. tax-filing history. Many ITIN programs aren't advertised, so you may need to ask lenders directly.
The ITIN loan often isn't permanent: once you obtain an SSN and build two years of U.S. credit and income history, refinancing into a lower-rate conventional loan becomes possible.
What credit history do ITIN lenders accept?
Many accept non-traditional credit when you have no FICO score: roughly 12 months each of rent, utilities, insurance or phone payments, documented with statements or letters from the provider. Some ITIN programs still prefer a scored file, so building U.S. credit widens your options.
Can I refinance out of an ITIN loan later?
Usually. Once you have a Social Security number and roughly two years of U.S. credit and documented income, conventional refinancing becomes possible — which is why many borrowers treat an ITIN loan as a stepping stone rather than a permanent arrangement.
