Columbia Business School’s Professor Stijn Van Nieuwerburgh spoke with PolitiFact reporter Louis Jacobson about how a proposed 50-year mortgage option could reshape the U.S. housing market. Van Nieuwerburgh explained that while longer-term mortgages may reduce monthly payments for buyers, they also extend debt burdens, limit equity accumulation, and could inflate home prices by increasing purchasing power without increasing supply. He emphasized that such policies risk worsening affordability challenges if not paired with measures to expand housing inventory.
