Quick answer: An ITIN mortgage lets you buy a home in the US using your Individual Taxpayer Identification Number instead of a Social Security Number. Guild Mortgage is the strongest national option with a dedicated ITIN program, while HomeAbroad specializes specifically in ITIN and foreign national borrowers. Expect a down payment of 10-25% and a rate roughly 0.5-2% above conventional loans — but for millions of ITIN filers, it’s the only path to homeownership available today.

What Is an ITIN Mortgage Loan?
An ITIN loan is a mortgage program that uses your Individual Taxpayer Identification Number — issued by the IRS to anyone required to file US taxes, regardless of immigration status — in place of a Social Security Number. Because these loans fall outside Fannie Mae and Freddie Mac guidelines, they’re classified as non-QM (non-qualified mortgage) products, meaning lenders typically hold them in their own portfolio rather than selling them to a government-sponsored enterprise. That classification is why ITIN loans carry higher down payments and rates — it reflects how the loan is funded, not the quality of the borrower.
Typical Requirements
- A valid ITIN and typically two years of filed US tax returns
- Down payment of 10-25%, depending on the lender and your credit profile
- Verifiable income — tax returns, bank statements, or documented self-employment income
- Credit history — many lenders accept alternative data like rent, utility, and phone bill payments if you have no traditional US credit score
- Cash reserves in a US bank account, seasoned for at least 2-3 months before applying

Guild Mortgage: Best for National Availability
Guild Mortgage runs one of the most established ITIN programs among larger lenders, requiring a valid ITIN and generally two years of filed tax returns. It reviews alternative credit documentation for borrowers without a traditional US score and is available in most states, making it a strong first call for a wide range of ITIN applicants.
HomeAbroad: Best for Foreign Nationals and ITIN Combined
HomeAbroad specializes specifically in ITIN and foreign national mortgage products, accepting foreign credit reports and international bank references alongside standard documentation. This makes it particularly useful for recent arrivals who have strong financial histories abroad but haven’t yet built a US credit file.
Flagstar Bank: Best for a Traditional Bank Relationship
Flagstar is one of the larger bank-name lenders that offers ITIN mortgages, giving borrowers who prefer working with an established, regulated bank (rather than a non-bank lender) a credible path to an ITIN loan.
Credit Unions and CDFIs: Best for Flexible Underwriting
Community Development Financial Institutions and local credit unions frequently offer the most flexible ITIN mortgage terms, since regulatory allowances give them more room to manually underwrite based on your full financial picture rather than rigid automated criteria. The tradeoff is that most require membership tied to your employer, community, or region.
How to Improve Your ITIN Mortgage Approval Odds
- Season your down payment funds in a US bank account for at least 2-3 months before applying.
- Build alternative credit documentation — rent, utility, and phone payment records — if you don’t have a traditional credit score yet.
- Keep two years of consistent, documented income, ideally with tax returns that match your bank deposits.
- Shop multiple ITIN-specialized lenders — rates and down payment requirements vary meaningfully between them.
