The source material examines former President Donald Trump’s November 2025 proposal for 50-year mortgages, an idea positioned as a modern solution to the ongoing housing affordability crisis. This extensive analysis explores the mechanics and implications of such an extended loan term, noting that while it significantly lowers monthly payments to benefit young or first-time buyers, it also dramatically increases total interest costs and slows equity building over time. The document provides historical context, contrasting the proposal with President Franklin D. Roosevelt’s creation of the 30-year fixed-rate mortgage during the Great Depression. Furthermore, it details the controversy surrounding the plan, citing critics who view it as a debt trap that could inflate home prices and increase systemic financial risk, particularly given the regulatory hurdles imposed by the post-2008 Qualified Mortgage rule.
