Buying a house with an ITIN in Florida: the honest guide

If someone offers you "the approved ITIN loan," be wary. What exists are specific paths, and they are checked with paperwork and quotes, not with promises.

The ITIN (Individual Taxpayer Identification Number) is a 9-digit number that starts with 9. The IRS, the federal tax agency, issues it to people who must file taxes and cannot get a Social Security number. It looks like a Social Security number, but it is not one.

What it is not, according to the IRS itself:

• It is for federal tax purposes only.
• It gives no permission to work and does not change your immigration status.
• It gives no Social Security benefits.
• It is not a loan, or a pre-approval. No federal agency publishes a program called an "ITIN loan." What exists are products each lender defines.

For any tax question, the IRS website or a tax professional. For questions about your immigration status, an immigration attorney. This guide gives advice on neither.

You apply with the IRS Form W-7 (it comes in Spanish too: W-7(SP)), together with your federal tax return, unless you meet one of the exceptions the form lists. It asks for documents proving your foreign status and your identity. There are several official ways: by mail or courier, at an IRS Taxpayer Assistance Center (by appointment only) or through an authorized Acceptance Agent. Some agents charge for their help: ask the cost in writing first.

The IRS says to count on 7 weeks to hear back, and 9 to 11 weeks if you file between January 15 and April 30, or from abroad. If you plan to buy, get the ITIN sorted before you fall for a house, not during the contract.

1. A conventional loan the lender sells to Fannie Mae or Freddie Mac. These two companies buy loans from lenders. They accept people who are not citizens if they are legal residents, permanent or non-permanent, on the same terms as a citizen. What they look at is your documented legal residency, not the tax number. Fannie Mae sets no single document: the lender decides how to establish it. And a loan to someone without legal residency in the United States is not eligible to be sold to Freddie Mac.

2. FHA, closed to non-permanent residents. The costliest myth is "get FHA with your ITIN." In Mortgagee Letter 2025-09, HUD removed eligibility for non-permanent residents for FHA cases assigned from May 25, 2025. Lawful permanent residents remain eligible, on the same terms as a citizen. If you are not one, FHA is not your path, ITIN or not.

3. Each lender's own product. Outside the agencies is the loan a lender keeps in its own portfolio or sells to private investors. There is no national rule: each one decides whether it works with buyers who file with an ITIN, what documents it asks for, how much down payment it requires and how much it charges. That is why this guide has no list of lenders: no official source maintains one, and a list copied from the internet would be made up.

Do down payment assistance programs accept an ITIN? The program cards on this site do not state that they accept it or reject it. Each program sets its own rules on identification, residency and income, so it is confirmed program by program with whoever administers it. Start with the guide on down payment help in Miami-Dade.

Documents that lenders working this profile tend to ask for. This is not an official list: it is common practice, and each lender confirms its own. If you are asked for something very different, or for money up front with no paperwork, stop and ask.

• Your ITIN assignment letter from the IRS, with the number still valid.
• Your recent tax returns filed with that ITIN.
• Photo ID and, if the path requires it, the residency document the lender determines.
• Proof of income and of employment or self-employment.
• Bank statements showing the down payment, with the source of the money clear.
• Payment history that complements a traditional credit history: rent, utilities and any credit that already reports.

• They cannot discriminate against you for your national origin. The law (ECOA) prohibits a lender from denying you credit, discouraging you from applying, or charging you more because of your national origin, among other reasons. They can evaluate your income, your debts and your history. If you suspect otherwise, you can complain to the CFPB, the federal agency that protects consumers.
• You can compare in writing. The CFPB recommends getting at least three Loan Estimates, the standard form with each lender's costs and terms. The lender must give you one within three business days of your application. Before closing you receive the Closing Disclosure with the final figures to compare against it. More on those costs in closing costs in Florida.
• Nobody can assure you an approval. A real pre-approval comes from your complete file reviewed by the lender (the difference is in pre-approval vs pre-qualification).
