Why are ITIN mortgage rates higher than conventional?

ITIN mortgages cannot be sold to Fannie Mae or Freddie Mac because the borrower lacks an SSN. The originating lender holds the loan on its own portfolio, which ties up capital and increases regulatory cost. The rate premium covers that capital cost plus the manual-underwriting overhead.

How do I get the best ITIN mortgage rate?

Maximize down payment (25% or more drops the rate the most), build a 24-month ITIN credit history with 720+ FICO before applying, keep DTI below 35%, and shop 3+ ITIN-specialist lenders for quotes. Credit unions and CDFI lenders typically beat for-profit lenders on rate by 25-75 basis points.

Can I refinance an ITIN mortgage to conventional after getting an SSN?

Yes. Once an SSN is issued and the ITIN is retired, the borrower can refinance to a conventional Fannie Mae or Freddie Mac loan at the prevailing conforming rate. The ITIN credit history merges with the SSN file, and the existing on-time payment record helps the refinance qualify.

Are ITIN ARM rates lower than ITIN fixed rates?

Yes. ITIN adjustable-rate mortgages (5/1, 7/1, 10/1 ARMs) typically start 75-125 basis points below the fixed-rate equivalent. The ARM resets to a market-linked rate after the fixed period, which is acceptable if the borrower plans to refinance or sell before the reset.
