Yes, you can buy a house with an ITIN number, but not through the mortgage programs most U.S. buyers use. ITIN borrowers qualify through a smaller group of specialized lenders offering non-qualified mortgages, which typically require 10 to 20 percent down and carry interest rates roughly 1 to 3 percentage points above conventional loans. Qualifying leans on your tax returns and alternative credit history rather than a Social Security Number-linked credit score.
Which Mortgage Programs Are Open to You
Conventional conforming loans are closed to ITIN borrowers. Fannie Mae requires lenders to validate every borrower’s Social Security Number with the Social Security Administration, and a loan that fails that validation cannot be sold to Fannie Mae.1Fannie Mae. General Borrower Eligibility Requirements Freddie Mac imposes the same requirement.
Government-backed loans are closed too. FHA loans require SSN validation through FHA Connection, and VA and USDA loans also require an SSN. Advertisements suggesting you can get an FHA loan with an ITIN are wrong. Don’t spend application fees on those programs.
What’s open to you is the non-qualified mortgage, usually called a non-QM loan. These are legitimate mortgage products that don’t meet the Consumer Financial Protection Bureau’s specific “qualified mortgage” criteria. The lender keeps the loan on its own books — portfolio lending — instead of selling it, which gives it room to underwrite your file using tax returns and alternative credit instead of an SSN-linked score.
Where To Find a Lender
Because the mainstream mortgage marketplace isn’t an option, where you shop matters. Community Development Financial Institutions (CDFIs) are among the most active ITIN lenders. They’re mission-driven organizations focused on underserved communities, and many are exempt from certain qualified mortgage requirements that would otherwise block these loans. Credit unions serving immigrant communities are another common source.
Some regional and community banks with under $10 billion in assets have additional regulatory flexibility to hold non-QM loans in portfolio. A handful of larger non-QM lenders also offer ITIN products nationwide. Start locally with CDFIs and credit unions, then widen the search. Rates and terms vary more in non-QM lending than in the conventional market, so apply with at least three lenders and compare their written offers.
Check That Your ITIN Is Still Active
The IRS deactivates any ITIN that hasn’t been used on a federal tax return for three consecutive tax years. Expiration takes effect on December 31 following that third year of non-use.2Internal Revenue Service. How To Renew an ITIN A lender can’t process your application with an expired number.
Renewal means filing Form W-7 with the IRS, checking the renewal box, and submitting original identification documents or certified copies — a passport is the most common. Processing takes several weeks, and from mid-January through April it can run longer.2Internal Revenue Service. How To Renew an ITIN Handle the renewal well before you start house hunting.
What Lenders Look For
Credit History
Most ITIN applicants don’t have a credit score with the major bureaus, so lenders evaluate you through alternative trade lines. These are recurring bills you pay on time that don’t typically appear on a credit report: rent, utilities, phone, car insurance, and similar obligations. Lenders generally want to see at least two trade lines with twelve consecutive months of on-time payments. Some lenders who do pull a traditional credit report tier their requirements by score, with stronger scores unlocking lower down payments.
Employment and Income
Expect a two-year work history in the same line of work. That doesn’t have to mean two years at one employer, but the employment should be continuous and consistent. Self-employed applicants face more scrutiny and typically need two years of tax returns showing stable or growing income from a profitable business.
Debt-to-Income Ratio
Lenders divide your total monthly debt payments, including the projected mortgage payment, by your gross monthly income. Most ITIN programs cap this ratio between 43 and 50 percent, depending on the lender and the overall strength of your file. Paying down existing balances before you apply can move you into a stronger tier.
Down Payment
ITIN loans ask for more cash upfront than FHA (3.5 percent with an SSN) or conventional loans (as low as 3 percent). Most ITIN lenders want 10 to 20 percent down. Borrowers with stronger alternative credit tend to qualify near the lower end; thinner files land closer to 20 percent.
The money has to be “seasoned,” meaning it has to have been in your bank account for a period before closing. Some lenders accept 30 days of statements; others want 60 to 90. The point is to confirm the funds are yours and didn’t come from an undisclosed loan.
Part of the down payment can come as a gift. Under Fannie Mae guidelines, for a primary residence with at least 20 percent down, the entire down payment can be gifted. If you’re putting down less than 20 percent on a two-to-four-unit property or a second home, at least 5 percent must come from your own funds before gift money can supplement the rest. Your ITIN lender may apply stricter rules since it’s underwriting to its own standards. Every gift needs a signed letter from the donor stating the dollar amount, confirming no repayment is expected, and listing the donor’s name, address, phone number, and relationship to you.3Fannie Mae. Personal Gifts
Cash Reserves
Beyond the down payment, lenders typically want to see about six months of mortgage payments, including taxes and insurance, held in liquid accounts after closing. Some lenders reduce or waive this if you’re borrowing less than 75 percent of the home’s value.
Paperwork To Pull Together
ITIN applications involve more documentation than conventional loans, and a single missing item can stall things for weeks. Gather everything before you submit.
Identity and ITIN Verification
You’ll need your CP565 notice, the official IRS letter confirming your ITIN assignment.4Internal Revenue Service. Understanding Your CP565 Notice If you’ve lost it, contact the IRS or a Taxpayer Assistance Center for a replacement. Most lenders also require a government-issued photo ID: a passport from your home country, a consular ID card, or a state driver’s license.
Income Documents
Federal tax returns for the two most recent filing years are the backbone of income verification. Returns must include all schedules and be signed. Salaried employees also provide W-2s and recent pay stubs covering at least 30 days. Self-employed applicants submit profit and loss statements and may need several months of business bank statements to corroborate reported income.4Internal Revenue Service. Understanding Your CP565 Notice
The Application
Every mortgage uses the Uniform Residential Loan Application, Form 1003, which collects your assets, monthly debts, employment, and housing history.5Fannie Mae. Uniform Residential Loan Application (Form 1003) Everything on it becomes a legal representation of your finances. Inconsistencies can kill an application entirely.
If You’re Applying With an SSN Holder
If one of you has an SSN and the other has an ITIN, the household must still use an ITIN loan product whenever the ITIN holder’s income is needed to qualify. The co-borrower’s SSN alone won’t open conventional loans in that situation. Both applicants provide their own ID and tax documents, and the lender underwrites the combined picture. Documented income from family members contributing to housing costs can generally be counted.
What It Costs
ITIN mortgage rates typically run 1 to 3 percentage points above conventional rates. On a $300,000 loan, a 2-point premium adds roughly $350 to the monthly payment and tens of thousands of dollars over the life of the loan. The premium reflects that the lender holds the loan in portfolio and carries all the default risk.
Most ITIN mortgages come as 30-year fixed-rate or adjustable-rate products. ARMs may offer a lower rate for an initial 5- or 7-year period before adjusting annually. If you expect to refinance into a conventional loan after obtaining an SSN or building traditional credit, an ARM can save money in the near term. If that refinance doesn’t materialize, you’re exposed to rate increases later.
Budget 2 to 5 percent of the purchase price for closing costs, paid at the closing table. These cover origination fees, the appraisal, title insurance, title search and recording fees, and prepaid escrow for property taxes and homeowner’s insurance. Manual underwriting on ITIN files can push origination fees slightly higher than on conventional loans. Ask for a Loan Estimate early so you can compare offers before committing.
Federal consumer protections still apply. Every mortgage must come with a Loan Estimate within three business days of application and a Closing Disclosure at least three business days before closing.
Most ITIN lenders also set up an escrow account at closing to handle property taxes and homeowner’s insurance. A share of each monthly payment flows into escrow, and the lender pays those bills when they come due. You’ll fund the account with an initial deposit at closing covering a few months in advance. Escrow amounts can change each year as tax bills and premiums shift, so your total monthly payment can rise even on a fixed-rate loan.
Your Rights as an Applicant
A lender cannot refuse to work with you or offer worse terms because of your national origin. The Fair Housing Act prohibits discrimination in any residential real-estate-related transaction, which expressly includes making or purchasing loans secured by residential real estate.6Office of the Law Revision Counsel. 42 US Code 3605 – Discrimination in Residential Real Estate-Related Transactions This protection applies regardless of immigration status.
A lender can apply different underwriting rules to an ITIN borrower — larger down payment, alternative credit documentation — because those are risk-based distinctions. A lender cannot refuse your application, raise your rate, or impose harsher terms based on your country of origin, accent, name, or ethnicity. If a lender crosses that line, you can file a complaint with the Department of Housing and Urban Development.
What Happens After You Apply
ITIN loans go through manual underwriting rather than the automated systems used for conventional loans. A human underwriter reviews every document, verifies employment with your employer, examines bank statements for unexplained deposits, and confirms your alternative credit references. That hands-on review is one reason ITIN files take longer to close.
The lender also orders a professional appraisal to confirm the property is worth at least the purchase price. If the appraisal comes in low, you can renegotiate with the seller, cover the gap with more cash, or walk away if your contract allows.
Once underwriting and the appraisal are done, the lender issues a “clear to close.” From application to clear-to-close typically runs 45 to 60 days. At closing, you sign the loan documents, deliver the remaining down payment and closing funds by cashier’s check or wire, and a title company or attorney records the deed with the local government.
Tax Benefits Once You Own
ITIN holders have the same access to the mortgage interest deduction as SSN holders. If you itemize on Schedule A, you can deduct interest paid on up to $750,000 of mortgage debt on your primary residence ($375,000 if married filing separately). State and local property taxes are deductible as well, subject to the $10,000 SALT cap. Your lender sends Form 1098 each January showing the interest you paid for the prior year. Filing consistently also keeps your ITIN active and builds the tax-return history that strengthens future refinancing and credit applications.
