Can I Buy a House With a Tax ID Number (ITIN) Instead of a SSN?

Last Updated: June 2026

TL;DR: Yes — you can buy a house in Texas using an Individual Taxpayer Identification Number (ITIN) instead of a Social Security Number (SSN). ITIN mortgage loans are specialized non-QM loans offered by portfolio lenders that typically require 10–20% down, two years of tax returns filed with your ITIN, and proof of stable income. Interest rates run about 0.5–2% higher than conventional mortgages.

Key Takeaways:

• An ITIN is a nine-digit tax processing number issued by the IRS for individuals who cannot get an SSN but need to file federal taxes
• ITIN loans are available in Texas through specialized lenders — not major national banks
• Most ITIN programs require 10–20% down, though some lenders offer options as low as 5% for qualifying borrowers
• Interest rates are typically 0.5–2% higher than conventional mortgages
• You do NOT need a Green Card or U.S. citizenship to buy property in Texas

What Is an ITIN and Who Qualifies for One?

An Individual Taxpayer Identification Number (ITIN) is a nine-digit tax processing number issued by the IRS to individuals who are required to have a U.S. taxpayer identification number but are not eligible to obtain a Social Security Number (SSN) from the Social Security Administration. ITINs begin with the number "9" and are designed solely for federal tax filing purposes.

According to the IRS, ITINs are available to nonresident aliens filing U.S. tax returns, resident aliens filing due to substantial presence in the U.S., and dependents or spouses of U.S. citizens or visa holders. An ITIN does not provide authorization to work in the U.S., eligibility for Social Security benefits, or immigration status — it is strictly a tax processing number.

To apply for an ITIN, you must submit Form W-7 along with original or certified copies of documents proving your identity and foreign status. A valid passport is the preferred document. The IRS typically processes ITIN applications in 7 to 14 weeks. ITINs must be used on a tax return at least once every three years to remain active.

Can You Really Buy a House With Just an ITIN?

Yes, you can. Texas law does not require U.S. citizenship, a Green Card, or an SSN to purchase property. Anyone with legal access to the U.S. can buy real estate, and ITIN holders can use specialized mortgage loans to finance the purchase.

According to Sully Ruiz, a licensed Texas REALTOR® (TREC #0742907) with Sully Realty Group who has helped 46+ families close on ITIN loans, the key is working with the right lender. "Many immigrants assume homeownership is impossible without an SSN, but ITIN loans are a proven path," she explains. "The process takes a bit more documentation, but families are doing it across the Austin metro every month."

It's important to understand that ITIN loans are not FHA loans. FHA loans require a valid SSN for the primary borrower. ITIN loans are non-Qualified Mortgages (non-QM) — meaning they don't meet the strict criteria of Fannie Mae, Freddie Mac, or FHA guidelines. Instead, they are portfolio loans held by the lenders that issue them, which gives lenders flexibility to set their own underwriting standards.

How Do ITIN Mortgage Loans Work?

ITIN mortgage loans function similarly to conventional mortgages in structure — you make a down payment, receive a loan for the remainder, and repay it over a set term (typically 30 years). The key differences are in who offers them, how underwriting works, and the pricing.

Because ITIN loans are non-QM portfolio loans, the lender keeps them on their own books rather than selling them to Fannie Mae or Freddie Mac. This means each lender sets its own requirements for credit history, income verification, and down payment — there is no single government standard.

Most ITIN loans are fixed-rate mortgages with 30-year terms. Some lenders also offer adjustable-rate options. The property being purchased must typically be your primary residence, though some lenders offer ITIN loans for second homes or investment properties at higher down payment requirements.

What Are the Requirements for an ITIN Home Loan?

ITIN loan requirements vary by lender, but most programs share these core criteria:

• Valid ITIN: You must have a current, unexpired ITIN issued by the IRS. If your ITIN has expired, you'll need to renew it before applying.
• Proof of Identity: A valid passport, consular ID (matrícula consular), or other government-issued photo identification.
• Income Verification: Two years of tax returns filed with your ITIN is the standard. W-2 employees should also provide recent pay stubs and an employer verification letter. Self-employed borrowers can use bank statements (typically 12–24 months) or profit-and-loss statements.
• Credit History: Many ITIN lenders accept alternative credit — consistent rent, utility, and insurance payments over 12 months — in lieu of a traditional FICO score. Some lenders require a minimum score around 580–660 if you do have a credit file.
• Proof of Residency: Utility bills, a lease, or other documentation showing you reside in the U.S.
• Debt-to-Income (DTI) Ratio: Most lenders allow a maximum DTI of 43–50%, similar to conventional loan standards.
• Property Type: ITIN loans are generally for primary residences. The property must meet the lender's condition standards.

According to Sully Ruiz, the most common obstacle isn't the requirements themselves — it's that borrowers don't know which documents to gather ahead of time. "Having two years of ITIN-filed tax returns, proof of income, and identification ready before you start the pre-qualification process saves weeks," she notes.

How Much Down Payment Do You Need?

Down payment is one of the biggest differences between ITIN loans and conventional mortgages. Here's what to expect:

Loan Type	Typical Down Payment	Notes
ITIN Loan	10–20%	Some lenders offer 5% down for strong profiles
Conventional	3–5%	PMI required under 20%
FHA Loan	3.5%	Requires SSN — not available to ITIN holders
VA Loan	0%	Requires military service + SSN
USDA Loan	0%	Rural areas only, income limits apply

According to Sully Ruiz, a licensed Texas REALTOR® (TREC #0742907) with Sully Realty Group who has helped 46+ families close on ITIN loans, most ITIN programs in Central Texas require a 10–20% down payment, though some lenders now offer options as low as 5% for qualifying buyers with stronger credit profiles and lower DTI ratios.

On a $350,000 home in the Austin metro (close to the area's median price), a 10% down payment would be $35,000, while 20% would be $70,000. This is a meaningful difference — and a key reason why many ITIN borrowers benefit from down payment assistance programs that can help cover a portion of the upfront cost.

ITIN Loan vs. Conventional Loan: How Do They Compare?

Feature	ITIN Loan	Conventional Loan
SSN Required?	No — uses ITIN	Yes
Minimum Down Payment	5–10% (varies by lender)	3–5%
Credit Score Minimum	580–660 or alternative credit	620+ typically
Interest Rate	~7–8.5% (as of June 2026)	~5.875–6.9% (as of June 2026)
Loan Term	Up to 30 years fixed	15 or 30 years fixed
PMI Required?	Varies by lender	Required under 20% down
Max DTI	43–50%	43–50%
Available from Major Banks?	No — specialized lenders only	Yes
Primary Residence Only?	Usually (some allow 2nd homes)	No restriction
Tax Benefits	Yes — mortgage interest deductible	Yes

What Interest Rates Can You Expect?

As of June 2026, conventional 30-year fixed mortgage rates in Texas average between 5.875% and 6.9%, depending on the lender and borrower profile. ITIN loan rates typically run 0.5 to 2 percentage points higher — meaning you might see rates in the 7% to 8.5% range.

The rate you receive depends on several factors:

• Down payment amount: Higher down payments generally unlock better rates
• Credit profile: Stronger alternative credit history can reduce your rate
• DTI ratio: Lower debt-to-income ratios signal lower risk to lenders
• Loan amount: Some lenders offer tiered pricing based on loan size
• Lender: Rates vary significantly between ITIN lenders — shopping around matters

While the higher rate is a trade-off, it's important to remember that ITIN loans offer something conventional loans cannot: a path to homeownership for families who file taxes but don't have an SSN. For many families, the long-term benefits of building equity and stability outweigh the rate premium.

Which Lenders Offer ITIN Loans in Texas?

ITIN loans are not available from major national banks. Instead, you'll work with specialized mortgage lenders, portfolio banks, credit unions, or mortgage brokers who have access to wholesale ITIN programs. Some Texas ITIN lenders include:

• NQM Funding — wholesale ITIN programs through brokers
• AsertaLoans — direct ITIN lender with Texas-specific programs
• Town Square Mortgage — ITIN mortgage options
• Hudson Sullivan — ITIN mortgage programs for non-citizens
• New American Funding — flexible ITIN borrower programs
• First National Bank of America — portfolio ITIN lending
• Carrington Mortgage Services — ITIN-friendly options

When choosing a lender, compare at least three offers. Ask about: interest rates, down payment minimums, income verification methods (tax returns vs. bank statements), and whether they offer purchase and refinance options.

Step-by-Step: How to Buy a House With an ITIN in Texas

1. Get your ITIN — If you don't have one yet, file Form W-7 with the IRS along with your tax return. Processing takes 7–14 weeks.
2. Gather your documents — Two years of tax returns filed with your ITIN, proof of income (pay stubs or bank statements), valid ID (passport or consular ID), and proof of residency.
3. Build alternative credit — If you don't have a traditional credit score, gather 12 months of on-time rent, utility, and insurance payment records.
4. Get pre-qualified — Contact an ITIN-friendly lender to get pre-qualified. This tells you your budget and shows sellers you're serious.
5. Save for your down payment — Aim for 10–20% of your target home price. Explore down payment assistance programs that may be compatible with ITIN loans.
6. Find a REALTOR® experienced with ITIN buyers — Work with someone who understands the ITIN process and can guide you through making offers, negotiating, and closing.
7. House shop and make an offer — Once pre-qualified, you can shop with confidence. Your REALTOR® will help you find homes in your budget across the Austin metro.
8. Close on your home — The closing process for ITIN loans is similar to conventional loans — typically 30–45 days from accepted offer to keys.

Common Mistakes to Avoid

• Not shopping between lenders — ITIN loan rates and terms vary significantly between lenders. Get quotes from at least three.
• Assuming you need 20% down — While 20% is ideal, many ITIN programs accept 10% and some go as low as 5% for strong profiles.
• Letting your ITIN expire — If you don't file taxes using your ITIN at least once every three years, it expires. Renew it before applying for a mortgage.
• Not preparing alternative credit — If you lack a traditional credit score, start documenting rent, utility, and insurance payments at least 12 months before applying.
• Working with an inexperienced agent — Not all REALTORS® understand ITIN transactions. Work with someone who has closed ITIN deals before. Book a free consultation with Sully to get started.
• Forgetting about closing costs — Beyond the down payment, budget 2–5% of the purchase price for closing costs, including title insurance, appraisal, and origination fees.

FAQ
