ITIN Mortgage Loans: How Non-US Citizens Can Buy a Home

Millions of people live and work in the United States, pay taxes faithfully, and dream of owning a home — but don't have a Social Security number. If you have an Individual Taxpayer Identification Number (ITIN), you may qualify for a mortgage even without a SSN.

What Is an ITIN?

The IRS issues ITINs to people who are required to file U.S. taxes but aren't eligible for a Social Security number. This includes non-resident aliens, resident aliens, undocumented immigrants, and foreign nationals with U.S. income. An ITIN begins with the number 9 and looks like: 9XX-XX-XXXX.

How ITIN Mortgages Work

ITIN mortgages are Non-QM loans offered by specialty lenders who have built underwriting guidelines specifically for borrowers without SSNs. They evaluate your application using:

Your ITIN and tax filing history (typically 2 years)
Proof of consistent income (pay stubs, bank statements, or employment letter)
Alternative credit history — rent payments, utility bills, remittance records
Solid down payment (typically 15–20%)

ITIN Loan Requirements

Valid ITIN: Must be current and active
Tax history: 2 years of ITIN tax returns (1040-NR or 1040 with ITIN)
Employment/Income: Verifiable income for 2+ years in same field
Down payment: 15–20% minimum
Credit history: 12+ months of on-time payments on any accounts
Residency: Must reside in the U.S. (primary residence only in most programs)

Building Credit Without a SSN

If you don't have a traditional credit score, lenders can use alternative credit — documented payment history on items like:

Rent (12-24 months of canceled checks or landlord letter)
Utilities, phone, insurance
International credit history
Money remittances (some lenders accept this)

What You'll Need to Apply

Valid photo ID (passport, consular ID, or matricula)
ITIN letter from the IRS
2 years of tax returns filed with your ITIN
2 years of employment history
Recent pay stubs or bank statements (60 days)
12+ months proof of on-time housing payments
Proof of down payment funds (seasoned 60+ days)

Can I Buy Any Type of Home?

Most ITIN mortgage programs are for primary residences — the home you'll live in. Some lenders also offer ITIN loans for investment properties, though down payment requirements are higher. Condos, single-family homes, and 2-4 unit properties are all eligible.

Finding the Right Lender

Most banks and credit unions don't offer ITIN mortgages at all. You need a Non-QM specialist. At AltLend Pro, we work with multiple ITIN-friendly lenders and can match you with the program that fits your situation — whether you've been here 2 years or 20.

We speak to your entire financial picture, not just your immigration status. If you have stable income, a solid down payment, and a history of paying your bills on time, homeownership is within reach.
