Short answer: yes, you can buy a home in Aurora, West Chicago, or anywhere in Illinois with an ITIN instead of a Social Security number. ITIN mortgages are offered by specialized lenders, and every year families across Chicago’s western suburbs use them to stop renting and start building equity.
I’m Rogelio Garcia, a bilingual Illinois real estate broker with Realty of America. I work with ITIN buyers in Aurora, West Chicago, and nearby towns, in English or Spanish, and I can introduce you to lenders who do these loans every day.
What Is an ITIN Mortgage?
An ITIN mortgage is a home loan for borrowers who file taxes with an Individual Taxpayer Identification Number issued by the IRS. Because these loans aren’t backed by FHA, Fannie Mae, or Freddie Mac, they’re offered as portfolio or non-QM loans by a smaller group of lenders. The rules are a little different from a conventional loan, but the home-buying process is almost the same.
How to Buy a Home with an ITIN: Step by Step
- Gather your documents. ITIN letter, photo ID, about two years of tax returns, bank statements, and proof of income.
- Get pre-approved by an ITIN lender. This tells you your price range, down payment, and estimated monthly payment.
- Pick your areas and start touring. Aurora and West Chicago both have a wide range of homes, townhomes, and condos.
- Make an offer. I’ll help you price it right and write strong terms for this market.
- Attorney review and inspection. In Illinois, both buyer and seller usually hire a real estate attorney, and you’ll have time for a home inspection.
- Close and get your keys. Most purchases close about 30 to 45 days after an accepted offer.
Why Aurora and West Chicago Work Well for ITIN Buyers
Aurora has one of the largest Hispanic communities in the Chicago suburbs, and West Chicago is a majority-Hispanic city with strong Spanish-speaking businesses and services. Both offer a mix of single-family homes, townhomes, and multi-unit properties, and both are on Metra lines into Chicago. As of August 2026, the median sale price was about $361,000 in Aurora and about $387,000 in West Chicago, according to Redfin.
Common Mistakes to Avoid
- Shopping for homes before you’re pre-approved.
- Moving money between accounts or making large deposits without paper trails right before applying.
- Opening new credit cards or financing a car while your loan is in process.
- Assuming you can’t buy because a big bank said no. Many banks simply don’t offer ITIN loans.
Frequently Asked Questions
Can I buy a house in Illinois with an ITIN number?
Yes. You do not need a Social Security number to buy a home in Illinois. Many buyers in Aurora and West Chicago purchase with an ITIN (Individual Taxpayer Identification Number) mortgage, a loan offered by specialized lenders rather than through FHA or conventional programs.
How much down payment do I need for an ITIN loan?
It depends on the lender, your credit, and the property. Many ITIN programs ask for roughly 10% to 20% down, and some lenders advertise lower minimums for well-qualified buyers. A lender who specializes in ITIN loans can tell you your exact number after reviewing your documents.
What documents do I need for an ITIN mortgage?
Most lenders ask for your ITIN letter, a valid photo ID such as a passport or consular ID, about two years of filed tax returns, recent bank statements, and proof of income. Some lenders accept alternative credit history, like rent and utility payments, if you don’t have a traditional credit score.
Are interest rates higher on ITIN loans?
Usually, yes. ITIN mortgages are considered non-QM (non-qualified mortgage) loans, so rates are typically higher than conventional or FHA loans. Many buyers refinance later if their situation changes.
Is there a real estate agent in Aurora who speaks Spanish and works with ITIN buyers?
Yes. Rogelio Garcia is a bilingual (English and Spanish) Illinois real estate broker with Realty of America who helps ITIN buyers in Aurora, West Chicago, and the surrounding western suburbs, and can connect you with lenders who specialize in ITIN loans.
How long does it take to buy a home with an ITIN loan?
Once you are pre-approved and have an accepted offer, closing usually takes about 30 to 45 days, similar to other loan types. Getting your documents together before you start shopping is the best way to avoid delays.
