Refinance With an ITIN Number: How It Works (2025)

By Wirly Editorial Team | Updated March 30, 2026 | AI-assisted, human-reviewed

Refinance With an ITIN Number: How It Works (2025)

Key Takeaways

  • Yes, you can refinance a mortgage using an Individual Tax Identification Number (ITIN) instead of a Social Security Number.
  • ITIN loan options are typically offered by credit unions, community banks, and specialized lenders – not conventional loan programs.
  • Interest rates on ITIN loans tend to be higher than conventional mortgage rates, so shopping multiple lenders is essential.
  • Refinancing with an ITIN affects your credit history the same way any mortgage application does, including hard inquiries on your credit report.

Can You Refinance With an ITIN Number?

Yes, it is possible to refinance a home loan using an ITIN. An Individual Tax Identification Number is a nine-digit number issued by the IRS to taxpayers who are not eligible for a Social Security Number. While most conventional mortgage programs require an SSN, a growing number of lenders offer ITIN loan programs that allow borrowers to purchase or refinance a home.

The application process is similar to a standard refinance, but the pool of available lenders is smaller. You will need to seek out lenders that specifically advertise ITIN mortgage programs.

What Is an ITIN?

An ITIN, or Individual Tax Identification Number, is issued by the IRS so that individuals without a Social Security Number can file taxes and comply with U.S. tax laws. It is formatted like an SSN (XXX-XX-XXXX) but always begins with the number 9. Having an ITIN does not grant work authorization or immigration status – it is strictly a tax identification number.

Where to Find ITIN Refinance Lenders

Not every lender offers ITIN loan products. Your best options typically include:

  • Credit unions: Many community-based credit unions serve ITIN holders. According to CFPB complaint data, credit unions like Navy Federal and PenFed tend to have strong timely response rates (100%) on mortgage complaints, though their ITIN offerings vary by location.
  • Community Development Financial Institutions (CDFIs): These mission-driven organizations often provide financing to underserved borrowers.
  • Portfolio lenders: Some banks keep loans on their own books rather than selling to Fannie Mae or Freddie Mac, which gives them flexibility to accept ITIN borrowers.

According to the Consumer Financial Protection Bureau, borrowers should compare at least three to five lender offers before choosing a mortgage or refinance. Use Wirly’s lender comparison tool to start your research.

Qualifying for an ITIN Refinance

Each lender sets its own guidelines, but common requirements for an ITIN mortgage refinance include:

  • Valid ITIN: Your individual tax identification number must be current and not expired.
  • Credit score: Many ITIN lenders require a minimum credit score, often 620 or higher. Some use alternative credit histories such as rent and utility payment records.
  • Tax returns: Typically two years of filed U.S. tax returns using your ITIN.
  • Down payment or equity: For a refinance, lenders usually require at least 20% to 30% equity in the home.
  • Debt-to-income ratio: Generally below 43% to 50%, depending on the lender.

Interest Rates for ITIN Loans

ITIN loan interest rates are generally 1% to 3% higher than conventional mortgage rates. This is because ITIN loans are considered non-qualified mortgages (non-QM), and lenders price in additional risk. According to Freddie Mac’s Primary Mortgage Market Survey, conventional 30-year rates have fluctuated significantly in recent years, so ITIN borrowers should expect rates above those benchmarks.

Shopping around is critical. Even small differences in your interest rate can save thousands over the life of the loan.

Risks and Considerations

Refinancing with an ITIN carries the same risks as any refinance, plus a few additional concerns:

  • Higher costs: Expect higher interest rates and potentially larger closing costs, including appraisal fees and title insurance.
  • Fewer lender options: A smaller pool of lenders means less competition and potentially less favorable terms.
  • Resetting your loan term: Refinancing into a new 30-year mortgage restarts your amortization clock, meaning you pay more total interest over time.
  • Credit score impact: Each lender application triggers a hard inquiry on your credit report. Multiple inquiries within a 14 to 45 day window are typically grouped as one by scoring models.
  • Break-even timeline: If you plan to move within a few years, the closing costs of refinancing may outweigh the savings.

According to CFPB complaint data from 2024, “applying for a mortgage or refinancing an existing mortgage” remains a common source of consumer complaints across major servicers, underscoring the importance of understanding your loan terms before signing.

Frequently Asked Questions

Does refinancing with an ITIN number affect my credit score?

Yes. The refinance application process involves hard credit inquiries, which can temporarily lower your credit score by a few points. Making timely payments on the new loan will help build your score over time.

Can I refinance with an ITIN number in California?

Yes. California has several credit unions and community lenders that offer ITIN mortgage and refinance programs. Availability varies by region, so contact local lenders or CDFIs directly.

Is an ITIN refinance the same as a regular refinance?

The basic process is similar – you apply, get appraised, and close on a new loan. However, ITIN refinances typically have higher interest rates, stricter equity requirements, and fewer lender options compared to conventional refinancing.

What documents do I need to refinance with an ITIN?

Most lenders require your valid ITIN, two years of U.S. tax returns, proof of income, bank statements, and documentation of your current mortgage. Some lenders may also accept alternative credit documentation like rent receipts or utility bills.
