Can I Buy a House in California With an ITIN Instead of a Social Security Number?

Last updated: September 2026 | California

Yes. You can buy a house in California using an Individual Taxpayer Identification Number (ITIN) instead of a Social Security number. A number of banks, credit unions, and portfolio lenders across California offer ITIN mortgage loans to buyers who don't have a Social Security number, as long as they can document steady income, hold a valid ITIN issued by the IRS, and typically make a larger down payment than a conventional loan requires.

What Is an ITIN Loan and Who Qualifies?

An ITIN loan is a mortgage designed for borrowers who file their taxes using an Individual Taxpayer Identification Number rather than a Social Security number. Instead of relying on a traditional credit score, many ITIN lenders build a credit profile from alternative documentation such as rent payment history, utility bills, and insurance payments. Borrowers generally need at least two years of consistent income, whether from W-2 employment, self-employment, or a combination of both, and a valid ITIN letter from the IRS.

How Much Down Payment Do I Need for an ITIN Loan in California?

Most ITIN loan programs require a down payment between 15% and 20% of the purchase price, higher than the 3.5% minimum on an FHA loan. Some credit unions and community lenders offer ITIN programs with down payments closer to 10% for well-qualified borrowers with strong reserves and a longer credit history. Because requirements vary widely between lenders, it's worth getting quotes from at least two or three institutions that specifically advertise ITIN mortgage programs.

What Documents Do I Need to Apply for an ITIN Mortgage?

Expect to provide your ITIN letter from the IRS, two years of federal tax returns, recent pay stubs or profit-and-loss statements if you're self-employed, two years of bank statements, and a valid form of photo identification such as a passport or matrícula consular. Lenders will also want to see a consistent address history and, in place of a FICO score, documentation of on-time payments for rent, utilities, or insurance going back at least 12 to 24 months.

Which Lenders Offer ITIN Loans in California?

ITIN mortgage programs are typically offered by community banks, credit unions, and portfolio lenders rather than the large national banks, since these loans usually aren't sold to Fannie Mae or Freddie Mac. Working with a loan officer who specifically advertises ITIN loan experience matters, because underwriting guidelines and required down payments can differ significantly from one lender to the next. Comparing at least a few offers can make a meaningful difference in your interest rate and closing costs.

ITIN Home Loan FAQ

Do I need to be a U.S. citizen to buy a house in California? No. You do not need to be a U.S. citizen or have a Social Security number to purchase property in California; an ITIN and proof of income are generally enough to qualify for an ITIN mortgage program.

Are interest rates higher on ITIN loans? Yes, typically. ITIN loan rates usually run higher than conventional or FHA rates because they carry more risk for the lender and are not backed by Fannie Mae or Freddie Mac.

Can I buy an investment property with an ITIN loan? Some lenders allow it, but most ITIN programs are built primarily for owner-occupied primary residences, so ask your lender directly about investment property guidelines.

How long does it take to close an ITIN home loan? Closing timelines are similar to conventional loans, generally 30 to 45 days from an accepted offer, assuming your documentation is complete and organized upfront.
