Yes, undocumented immigrants can buy a house in the US. No federal law ties property ownership to citizenship or immigration status, and property law is set at the state level, where the vast majority of states do not require buyers to prove legal status. The real obstacles are practical ones: financing, identification for tax purposes, and long-term tax exposure.
Paying Cash Is the Simplest Route
An all-cash purchase skips the hardest part of the process. There is no mortgage application, no Social Security Number requirement, and no credit history to build. The seller or title company will ask for proof of funds, usually a bank statement or letter, and a valid ID such as a foreign passport or consular card.
Federal anti-money-laundering rules do require financial institutions involved in closings to verify the identity of the parties using documents like passports, driver’s licenses, or credit reports. Those rules do not require proof of citizenship or legal residency.1U.S. Department of the Treasury. Treasury and Federal Financial Regulators Issue Patriot Act Regulations on Customer Identification A passport from any country satisfies the identity check. Title insurance, which protects you against later ownership disputes, is available on the same terms.
Getting an ITIN
Even a cash buyer needs an Individual Taxpayer Identification Number to file taxes on the property and claim deductions. The IRS issues ITINs to people who have a federal tax obligation but are not eligible for a Social Security Number.2Internal Revenue Service. Individual Taxpayer Identification Number (ITIN) An ITIN does not authorize work and does not change your immigration status. It exists only for tax purposes.
You apply on Form W-7. The cleanest supporting document is an original passport or a certified copy from the issuing agency, which proves identity and foreign status in one piece of paper. Without a passport, you need at least two other documents from the IRS’s accepted list, and at least one must include a photograph.3Internal Revenue Service. Instructions for Form W-7
If the ITIN request is tied directly to a property sale or purchase, Exception 4 on Form W-7 lets you apply without attaching a full tax return. You include a copy of the sales contract or closing disclosure along with the relevant withholding forms (Form 8288 or 8288-B).3Internal Revenue Service. Instructions for Form W-7
Financing With an ITIN Mortgage
Conventional mortgages backed by Fannie Mae or Freddie Mac require a Social Security Number, which closes off mainstream lending. A number of private lenders, credit unions, and community banks fill that gap with ITIN mortgages that accept an ITIN in place of an SSN.
The terms are tighter than conventional loans. Down payments typically run 10% to 25% of the purchase price, with most lenders asking for 15% to 20%. Interest rates run one to three percentage points above conventional rates because lenders keep these loans in their own portfolios rather than selling them on the secondary market. To qualify, you generally need at least two years of U.S. tax returns filed with your ITIN, proof of steady income, and enough savings for the down payment and closing costs. Some lenders will look at alternative credit data like rent and utility payments instead of a traditional credit score.
DACA recipients have less room than they used to. As of May 2025, the Federal Housing Administration removed the “non-permanent residents” category from its Title I and Title II programs, ending new FHA-insured mortgages for DACA recipients.4U.S. Department of Housing and Urban Development. HUD Cracks Down on Government-Backed Mortgages for Illegal Immigrants Existing FHA loans are unaffected, but new applicants have to look to private ITIN lenders.
Taxes and Deductions After You Buy
Owning property creates tax obligations regardless of status. Property taxes are the most immediate; local governments assess them annually, and falling behind can produce a lien and eventually a forced sale. You are also expected to file a federal income tax return each year using your ITIN.
Homeownership also opens up deductions if you itemize on Schedule A. Mortgage interest is deductible on up to $750,000 in mortgage debt ($375,000 if married filing separately), a cap that is now permanent under current law; mortgages taken out before December 16, 2017, may qualify for the older $1 million cap.5Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction Property taxes and other state and local taxes are deductible together under the SALT deduction, capped at $40,000 ($20,000 if married filing separately) with small increases each year through 2029.6Internal Revenue Service. Real Estate (Taxes, Mortgage Interest, Points, Other Property Expenses)
The mortgage interest deduction only covers interest on debt used to buy, build, or substantially improve the home. Interest on a home equity loan used to pay off credit cards is not deductible.6Internal Revenue Service. Real Estate (Taxes, Mortgage Interest, Points, Other Property Expenses) Filing accurate returns each year with your ITIN also builds the documented financial history that ITIN mortgage lenders want to see.
Capital Gains and FIRPTA When You Sell
Profit on the sale of a home is a capital gain subject to federal tax.7Internal Revenue Service. Topic No. 409, Capital Gains and Losses If you owned and lived in the home as your primary residence for at least two of the five years before the sale, you can exclude up to $250,000 of gain from income ($500,000 for married couples filing jointly).8Office of the Law Revision Counsel. 26 U.S. Code 121 – Exclusion of Gain From Sale of Principal Residence The exclusion is based on ownership and use, not on citizenship.
Undocumented sellers face an added rule: FIRPTA withholding. Federal law requires the buyer of U.S. real property from a foreign person to withhold 15% of the total sale price and send it to the IRS.9Office of the Law Revision Counsel. 26 U.S. Code 1445 – Withholding of Tax on Dispositions of United States Real Property Interests This is not a separate tax; it is a prepayment against your actual capital gains liability. If the withholding exceeds what you owe, you file a return with your ITIN and claim a refund.10Internal Revenue Service. ITIN Guidance for Foreign Property Buyers/Sellers
There is a residential exception. If the buyer intends to use the property as a personal residence and the sale price is $300,000 or less, no withholding is required.11Internal Revenue Service. Exceptions From FIRPTA Withholding For higher-value sales, you can apply on Form 8288-B before closing to request reduced withholding based on your expected tax bill.
The Estate Tax Trap
This is where immigration status creates the sharpest financial gap, and many buyers never see it coming. U.S. citizens and permanent residents receive a federal estate tax exemption of $15 million in 2026.12Internal Revenue Service. Whats New – Estate and Gift Tax Nonresident aliens receive $60,000.13Internal Revenue Service. Some Nonresidents With U.S. Assets Must File Estate Tax Returns An undocumented homeowner who dies owning U.S. property worth more than $60,000 can leave an estate exposed to federal estate tax on almost the entire value of the home. The top federal estate tax rate is 40%.
Gift tax rules split along the same line. U.S. citizen spouses can transfer unlimited property to each other tax-free. Transfers to a spouse who is not a U.S. citizen are limited to a special annual exclusion of $194,000 in 2026, and anything above that in a given year may trigger gift tax.14Internal Revenue Service. Frequently Asked Questions on Gift Taxes for Nonresidents Not Citizens of the United States For any undocumented buyer with meaningful equity, an estate attorney is worth the cost.
State Restrictions on Foreign Buyers
Federal law does not bar undocumented buyers, but state law is a separate matter. As of late 2025, roughly 36 states had some form of foreign ownership restriction, and several adopted or expanded laws during 2025. Most target citizens, businesses, and government entities of countries flagged as national security concerns, and most focus on agricultural land, though some reach residential property, mineral rights, and water rights.
Scope and penalties vary. Some laws apply only to government-affiliated buyers; others restrict individual citizens of designated countries. Penalties range from forced divestiture to criminal charges. An undocumented buyer who is not a national of a restricted country may be unaffected, but someone who is could face real consequences. Check the specific rules in your state before signing anything.
Fair Housing and Enforcement Realities
The Fair Housing Act protects against discrimination based on race, color, national origin, religion, sex, familial status, and disability.15Department of Justice. The Fair Housing Act Immigration status is not a protected category, so the Act does not directly bar a seller or agent from refusing to work with an undocumented buyer. In practice, discrimination against undocumented buyers often follows national-origin lines, which can give affected buyers a legal basis for action even when documentation is the stated reason.
Buying a home does not change your immigration status and does not shield you from deportation. Real estate transactions become part of public county records, and your name will appear on a deed that anyone, including federal agencies, can search. Owning property is not itself an immigration violation, and it also is not a protection.
The current enforcement climate adds pressure at the edges of the financial system. In 2025, the Treasury Department’s Financial Crimes Enforcement Network directed money services businesses to increase scrutiny of cross-border fund transfers involving undocumented individuals, consistent with executive orders on immigration enforcement.16Financial Crimes Enforcement Network. FinCEN Issues Alert on Cross-Border Funds Transfers Involving Illegal Aliens The alert targeted remittances rather than property, but it reflects a broader posture of financial scrutiny worth knowing about.
Using fraudulent identification or false information in a real estate transaction is a federal crime separate from any immigration violation. A valid foreign passport, consular ID, and properly obtained ITIN keep the transaction itself lawful.
Buying With a Family Member Who Has Status
Co-ownership with a family member or partner who has legal status is a common path. If the co-owner qualifies for a conventional mortgage, financing terms improve, and the financial load is shared.
The most common structure is tenancy in common, where each owner holds a defined percentage share. Shares can be unequal, and each person can sell or transfer their share independently. Joint tenancy requires equal shares and includes a right of survivorship, so one owner’s share passes automatically to the surviving co-owner at death.
Any co-ownership arrangement needs a written agreement covering each person’s contribution, who pays the mortgage and upkeep, what happens if one party wants to sell, and how profits are split. Without one, disputes end up in court, and an undocumented co-owner may be reluctant to pursue legal remedies, which makes the upfront agreement matter even more.
