Why Credit Scores Matter for Mortgages

Your credit score is one of the most important factors lenders consider when determining your mortgage interest rate. A higher score demonstrates to lenders that you're a lower-risk borrower.

  • Good credit (670-739): Still get competitive rates with most lenders
  • Fair credit (580-669): Higher rates, but conventional loans still possible
  • Poor credit (below 580): May need FHA loans or face significantly higher rates
