Credit Score Shake-Up: New Models Promise Broader Access—But Could Cost Lenders Billions
Mortgage scoring is being rewritten to widen access, but the shift could reshape lender economics and risk.
What is this trend?
Mortgage credit scoring is moving beyond legacy FICO toward newer, data-rich models that can include more borrowers while forcing lenders to adapt systems, compliance, and risk pricing.
- Alternative data like rent history can help score borrowers with thin or invisible credit files.
- Dual-score and newer-model adoption aims to broaden approvals without abandoning risk discipline.
- Lenders face costly tech, compliance, and workflow changes as scoring rules evolve.
- Broader access could open the door for first-time and moderate-credit buyers long excluded from mortgages.
- The transition may shift lender economics and create new concerns about model gaming and delinquency.
