The Mortgage Lending Explained newsletter is published with each new article and podcast episode. My monthly JSWhaldo newsletter focuses primarily on travel and lifestyle content, highlighting new projects and stories from across the site.
After more than 30 years in mortgage underwriting, I write these articles to help consumers understand how mortgage loans really work. My goal is to explain lending in plain English, separate fact from fiction, and provide insight into how mortgage underwriters evaluate loan applications.
Whether you're buying your first home, refinancing, exploring reverse mortgages, or simply curious about credit and lending, I hope you'll find useful information and practical answers here.
