ITIN

What is an ITIN and why do homebuyers ask about it?

An ITIN is an Individual Taxpayer Identification Number issued by the IRS for people who need a U.S. tax ID but are not eligible for a Social Security number. Some lenders and tax filings related to U.S. property use an ITIN. It is not a work permit or visa.
