VantageScore, FICO, and the Future of Mortgage Credit Models with Erin Wester & Tiffany McGarry | 10/6/2026

The mortgage industry is navigating one of its most significant credit scoring changes in decades. This week on Optimal Insights, Erin Wester, Tiffany McGarry, and Jim Glennon discuss the industry's transition to a multi-model credit environment, including the introduction of VantageScore 4.0 alongside traditional FICO models.

The conversation covers how lenders, investors, and technology providers are adapting to evolving credit model requirements, operational challenges, loan sale considerations, pricing impacts, underwriting workflows, and the uncertainty that remains as new guidance continues to emerge. The speakers also explore how future credit models could influence borrower affordability, competition, and mortgage technology roadmaps across the industry.

In the market update, Alex Hebner and James Cahill break down recent inflation data, employment trends, mortgage rate movement, Federal Reserve expectations, and what mortgage professionals should monitor ahead of upcoming CPI and PPI reports.
