Get ITIN Loan Pre-ApprovalKey Differences: ITIN vs Conventional
ITIN Loans: Non-QM mortgages designed for foreign nationals and non-permanent residents who don’t have Social Security numbers. Uses Individual Taxpayer Identification Number (ITIN) instead of SSN for credit and income verification. Requires 2 years of ITIN tax filing history and a 680 or higher credit score. Down payment depends on credit, property type, and lender guidelines. Pricing typically runs somewhat higher than conventional loans.
Conventional Loans: Standard mortgages backed by Fannie Mae or Freddie Mac requiring Social Security number for credit verification. Conventional loans generally require a Social Security number and eligible residency status. Some non-permanent residents may qualify, while borrowers with only an ITIN typically do not, which is where ITIN programs come in. Lower down payments (3-20%), competitive interest rates, and strict qualification standards including 620+ credit score and 43% DTI maximum.
Critical Distinction: the dividing line is the Social Security number, not immigration status. An ITIN loan is built for a borrower who files taxes with an ITIN and does not have an SSN. Conventional financing generally requires a valid SSN, and US citizens, permanent residents, and non-permanent residents with acceptable work authorization and an SSN may qualify, depending on credit, equity, income, property type, and lender guidelines. ITIN loans are portfolio products and price above conventional; conventional loans are sold to Fannie Mae and Freddie Mac.
What Each Program Asks For: the ITIN program requires a valid ITIN and a tax filing history under it. Conventional financing generally requires a valid Social Security number. Which program fits you depends on your documentation, credit, equity, income, property type, and lender guidelines, and we confirm it before you apply.

Example Scenarios
Scenario 1: ITIN Loan for Foreign National
Borrower Profile: Self-employed consultant, age 35, working in California, not SSN-eligible; files U.S. taxes with an ITIN, 3 years of filing history. Annual income $120,000.
- Purchase price: $700,000
- Down payment: 20% ($140,000)
- Loan amount: $560,000
- Credit score: 710 (ITIN credit file)
- Term: 30-year fixed
- Gross monthly income: $10,000
- DTI: Within ITIN program limits (which allow higher DTI than conventional)
- Result: may qualify for an ITIN loan, since conventional financing generally requires an SSN
Scenario 2: Conventional Loan for Permanent Resident
Borrower Profile: Registered nurse, age 42, working in California, SSN-eligible. Has SSN and 5 years US credit history. Annual income $95,000.
- Purchase price: $650,000
- Down payment: 10% ($65,000)
- Loan amount: $585,000
- Credit score: 720 (SSN credit file)
- Term: 30-year fixed
- Gross monthly income: $7,917
- DTI: Comfortably within conventional limits
- Result: Approved with conventional loan (lower rate, lower down payment)
Bottom Line: an ITIN loan opens homeownership to a borrower without an SSN, and it costs more, in both rate and down payment. Conventional financing offers better terms but generally requires a valid SSN. If you later obtain an SSN, refinancing to conventional may be an option worth reviewing at that point.
Which Option Should You Choose?
Choose ITIN Loan If
- You don’t have Social Security number
- You’re foreign national or non-permanent resident legally working in US
- You have ITIN with 2+ years tax filing history
- You have 680+ credit score (ITIN credit file)
- You have a down payment ready; how much depends on credit, property type, and lender guidelines
- You’re willing to pay a somewhat higher interest rate
- You want to buy California real estate now, without waiting on an SSN
Choose Conventional Loan If
- You have Social Security number
- You meet the program’s residency and documentation requirements
- You have 620+ credit score (SSN credit file)
- You want the lower pricing conventional financing generally carries
- You want lowest down payment option (3-20%)
- You qualify for conventional loan standards (43% DTI, income verification)
For a borrower who files taxes with an ITIN and has no Social Security number, an ITIN loan is generally the route to a mortgage. Conventional financing offers better terms but generally requires a valid SSN. If an SSN is likely in your future, buying now on an ITIN loan and reviewing a refinance to conventional later is a path worth comparing, depending on credit, equity, income, property type, and lender guidelines.
What is the difference between an ITIN loan and a conventional loan?
An ITIN loan lets you qualify using an Individual Taxpayer Identification Number instead of a Social Security number, while conventional loans require an SSN and are limited to U.S. citizens and permanent residents. ITIN loans are non-QM portfolio products with somewhat higher rates and larger down payments; conventional loans offer lower baseline pricing but stricter eligibility. If you work legally in the U.S. without an SSN, an ITIN loan may be your only realistic path to a mortgage, subject to qualification and lender guidelines.
Can I get a mortgage without a Social Security number?
Yes — ITIN loans are specifically designed for borrowers without SSN. You need a valid Individual Taxpayer Identification Number (ITIN) with at least 2 years of tax filing history. These are non-QM portfolio loans with slightly higher rates but enable homeownership for foreign nationals and non-permanent residents.
Can I get an ITIN mortgage in California?
Yes — ITIN mortgage programs are available throughout California for primary homes, second homes, and investment properties. As a mortgage broker, Solve Lending & Realty can compare ITIN programs across multiple wholesale sources rather than being limited to one bank’s guidelines. You’ll generally need an ITIN with tax filing history, established credit, and a larger down payment than a conventional loan; exact terms depend on credit, income, and lender guidelines.
What documentation do I need for an ITIN loan?
Typical ITIN loan documentation includes: valid ITIN letter from IRS, 2 years ITIN tax returns, valid passport or consular ID, proof of US residence, bank statements (12-24 months), employment verification or business documentation, and down payment source documentation. Requirements vary by lender.
Can I refinance from ITIN to conventional after getting my green card?
Yes — once you obtain Permanent Resident status and a Social Security number, you can refinance from an ITIN loan into a conventional mortgage, which typically prices lower than non-QM. Whether your payment actually drops depends on market rates, your credit, and your equity at that time; with 20%+ equity you may also avoid PMI. It’s a common long-term plan for ITIN borrowers, subject to qualification and lender guidelines.
How do I build credit with an ITIN?
Several credit card issuers and credit unions accept ITIN applications. Start with a secured credit card, make consistent payments for 12-24 months, and you’ll build an ITIN credit file. Some lenders also accept alternative credit (rent payments, utility bills, phone bills) for ITIN borrowers with limited traditional credit history.
Are ITIN loans available for investment properties?
Yes — most ITIN lenders offer financing for primary residences, second homes, and investment properties. Investment property ITIN loans typically require larger down payments (25-30%) and may have slightly higher rates. Some investors combine ITIN loans with DSCR qualification for rental properties.
Does my immigration status affect loan approval?
ITIN lenders focus on your ability to repay — income, credit, and assets — rather than your specific visa type, though you must be legally authorized to work in the U.S. with a valid ITIN and tax filing history. A mortgage application is a financial transaction, not an immigration matter. If your status may change soon (for example, a pending green card), tell your broker — it can shape which loan makes sense now versus later.
