Most first-time homebuyers in the United States take out 30-year mortgages. Under a new proposal from the Trump administration, they may soon have an even longer loan option. This week, President Donald Trump introduced a new idea to tackle home affordability: a 50-year mortgage loan. Federal Housing Finance Agency Director Bill Pulte called the proposal “a complete game changer.” While Trump’s proposal is light on details, administration officials say a 50-year mortgage would lower monthly payments, helping more Americans currently priced out of the market.
