The US government is considering a 50-year mortgage plan, which has faced criticism from various stakeholders. While it could lower monthly payments, it may lead to significantly higher interest costs and slow equity accumulation. Critics argue it doesn't address core housing market issues like supply shortages and high costs. The average age of first-time homebuyers is now 40, raising concerns about the viability of such long loans. President Trump has downplayed the idea, and legislative changes would be required to implement it.
