ITIN Loans: Non-QM mortgages designed for foreign nationals and non-permanent residents who don't have Social Security numbers. Uses Individual Taxpayer Identification Number (ITIN) instead of SSN for credit and income verification. Requires 2 years ITIN tax filing history, 680+ credit score, and 15-25% down payment. Interest rates typically 0.5-1.5% higher than conventional loans.
Conventional Loans: Standard mortgages backed by Fannie Mae or Freddie Mac requiring Social Security number for credit verification. Available to US Citizens and Permanent Resident Aliens (green card holders) only. Lower down payments (3-20%), competitive interest rates, and strict qualification standards including 620+ credit score and 43% DTI maximum.
Critical Distinction: ITIN loans enable homeownership for non-citizens legally working in US without SSN. Conventional loans require SSN and are limited to US Citizens and Permanent Resident Aliens. ITIN loans are portfolio products with higher rates. Conventional loans are sold to Fannie/Freddie with lower rates.
Legal Status Requirement: ITIN loans require legal work authorization in US with valid ITIN and tax filing history. Conventional loans require US Citizenship or Permanent Resident status with Social Security number.
