An ITIN mortgage is for borrowers living in the US who pay taxes using an ITIN but lack a Social Security Number, typically requiring 10% to 25% down and US tax returns. A foreign national mortgage is intended for non-resident borrowers living abroad who want to buy property in the US; this usually calls for 25% to 40% down and qualification through international assets or rental income. The right option always comes down to your residency and where you file taxes.
Understanding the core difference
Over my years guiding clients at Heart Mortgage, I have often seen confusion between ITIN and foreign national mortgages. The line is straightforward: ITIN mortgage programs are for those physically living in the United States and earning here, while foreign national programs are designed for people living overseas with no US tax presence.
- ITIN mortgages: for buyers in the US without Social Security Numbers but who file US taxes using an Individual Taxpayer Identification Number.
- Foreign national mortgages: for those who live and work outside the US and want to purchase a second home or investment property in America.
What I notice is that some guides mix up eligibility, but keeping these categories clear is key to a smooth loan process. The requirements change dramatically depending on which one fits your case. I see clients lose months pursuing the wrong product, so I want to lay out the facts as plainly as possible here.

Breaking down ITIN mortgage definition and requirements
An ITIN (Individual Taxpayer Identification Number) is a nine-digit number beginning with “9” that lets non-citizens file federal taxes if they don’t qualify for a Social Security Number, according to guidance from the Consumer Financial Protection Bureau. Many of our clients at Heart Mortgage use their ITIN to buy a first home, usually as primary residence or investment property.
Standard lender requirements for ITIN programs include:
- Valid, unexpired ITIN issued by IRS
- Two years of full US tax returns with ITIN as ID
- Proof of US-based income (W-2, paystubs, or self-employed records such as bank statements, 1099, or Profit & Loss statements)
- Down payment between 10% and 25% depending on credit and property type
- Credit score ideally 580–660 (or twelve months of timely rent and utilities payments as alternative verification)
- Valid passport or government-issued photo ID
- Debt-to-income ratio up to 50%
I work with buyers who are self-employed, and lenders accept as proof twelve to twenty-four months of bank statements or third-party profit and loss statements. Guidance on acceptable ITIN lending is shaped by Qualified Mortgage rules and the Equal Credit Opportunity Act. Lenders are prohibited from discriminating based on national origin or immigration status if all income is verifiable and legal.
What sets foreign national mortgage programs apart?
Foreign national loans offer an avenue for non-residents wanting to own US property with no US tax ties. These are non-Qualified Mortgage “non-QM” programs, which are underwritten by portfolio lenders rather than Fannie Mae or Freddie Mac. I often see foreign nationals applying from Brazil, Europe, or Asia, with these main requirements:
- Valid passport from a non-sanctioned country (OFAC restrictions apply)
- No ITIN or SSN needed at all
- No US credit score required (some want a letter or score from a foreign bank)
- Down payment from 25% to 40%
- Foreign income/asset verification, such as international bank statements or employer letters
- Cash reserves: at least six to twelve months of payment, typically seasoned for at least sixty days
- Eligible properties: second homes or investment property only, not primary homes
- Loans typically up to $2 million (sometimes $5 million), rates sitting about 1.5% to 3% higher than conventional loans due to risk and paperwork
- US LLC often used for the title
- Closing takes about 45 to 60 days
- Many programs allow debt-service coverage ratio (DSCR) qualification using projected rents
Both program types are covered by anti-discrimination rules, and underwriters will require that income is traceable and legal. If you want to know more on the technical side, market application and closing volume data tracks both ITIN and foreign national programs as part of the overall non-QM pool. This is a reassuring sign for those worried about regulatory risks.
How real-life scenarios play out
I want to make this less abstract, so here are scenarios I’ve encountered with Heart Mortgage clients:
- First-time buyer in the US (no SSN, has ITIN): With tax returns, this client can buy a primary home for 15%–20% down using an ITIN mortgage. The lender will check their job and savings in America.
- Investor living abroad (for example in Brazil): No US income or tax returns needed—this buyer can get a foreign national mortgage (often using DSCR, which allows rental income to count for qualification), usually 25%–30% down. If you’re curious how this works, I highly recommend our guide to foreign national mortgages or deep-dive on non-citizen property financing.
- ITIN holder who wants rental property: Some lenders can use either ITIN or foreign national terms—so an experienced broker at Heart Mortgage will compare both for better rates or lower down payment.
- No US credit score: ITIN programs allow for alternative credit review (with bills/rent payments), while foreign national options accept absence of credit with a bigger down payment and more reserves.
What US regulations say about these programs
Lenders who offer ITIN and foreign national loans must follow the rules established by the CFPB, Fair Housing Act, and the Equal Credit Opportunity Act, which all prohibit discrimination based on citizenship, nationality, or immigration status. Both loan types are considered “non-QM”, lacking some consumer protections described by Qualified Mortgage regulations. As a result, terms may be less flexible, and buyers should always check all disclosures carefully, including repayment obligations and risk of higher fees.
For up-to-date research and new program developments, I find it helpful to keep an eye on the CFPB National Survey of Mortgage Originations and FFIEC releases on lending market trends.

Frequently asked questions
What is an ITIN mortgage in the US?
An ITIN mortgage is a home loan offered to people living in the US who do not have a Social Security Number but file taxes with an Individual Taxpayer Identification Number (ITIN). The ITIN, issued by the IRS, enables applicants to show US tax history and legal income, and allows for home financing even if their immigration status does not permit a traditional loan. More details are available in this detailed guide on ITIN mortgages.
What are the requirements for ITIN mortgages?
Most lenders need a valid ITIN, at least two years of tax returns with ITIN as ID, proof of US-based income (like paystubs, W-2 forms, or bank deposits for the self-employed), a down payment of 10% to 25%, and either a 580–660 credit score or proof you paid rent and utility bills on time for a year. This is covered in depth by CFPB guidance.
How do foreign national mortgages work?
Foreign national mortgages allow non-US residents who live and earn abroad to buy property in the United States. These loans use foreign bank records or employer letters for income, do not require a US tax ID or Social Security Number, and ask for a higher down payment (usually 25% or more). See our step-by-step foreign national mortgage overview for a complete breakdown.
Which lenders offer ITIN mortgage programs?
Specialized non-QM lenders, many of which partner with Heart Mortgage, focus on ITIN mortgage programs. These lenders know how to work with tax, credit, and ID documentation common for ITIN borrowers, and they are not the mainstream banks that require SSNs for all applications. You can learn more about application steps and documents in this ITIN application guide.
Is it worth it to get an ITIN mortgage?
For many people, an ITIN loan is the only practical way to buy a house in the US if they lack a Social Security Number. The down payment and rates are higher than traditional loans, but building home equity and establishing US credit history can make it worthwhile. Carefully compare offers and terms so you can choose what’s right based on your goals and situation.
