President Donald Trump floated an idea recently that managed to do something pretty rare: unite critics from his own party against him. His proposal? Fifty-year mortgages to tackle America's housing affordability crisis.

The logic seems straightforward enough—stretch the loan over five decades instead of three, and monthly payments drop. But the backlash has been swift and brutal, particularly from conservative lawmakers and MAGA supporters who see this as creating a debt trap rather than solving a problem.

The GOP Pushback

Rep. Marjorie Taylor Greene didn't mince words when she took to X to slam the proposal.

"I don't like 50-year mortgages as the solution to the housing affordability crisis … In debt forever, in debt for life," Greene wrote.

Instead, Greene suggested alternative approaches: stopping large corporations from buying up single-family homes to convert into rentals, and eliminating capital gains taxes on primary home sales.

"This will help people keep the equity they have earned owning their home for a very long time and likely allow them to lower the price of their home for sale since they won't be paying taxes after they sell their home," she explained.

The criticism extends beyond Greene. Conservative lawmakers and several economists have warned that extending mortgage terms to 50 years would leave families stuck in long-term debt while dramatically slowing their ability to build equity.

What the Experts Say

Financial professionals share similar concerns about the mechanics of such extended loans.

"It would lead to buyers building equity in their homes more slowly. At the beginning of the mortgage, more of those payments tend to be interest," said Gennadiy Goldberg, head of U.S. rates strategy at TD Securities, per Politico.

"This is more of a stopgap bandaid to address affordability," Goldberg added.

The math is pretty brutal. A 50-year mortgage means homebuyers would pay vastly more in total interest over the life of the loan compared to a traditional 30-year mortgage, making the house significantly more expensive in the long run.

There's another wrinkle, too. Critics warn that extending loan terms might actually push housing prices higher by increasing buyer demand without fixing the real problem: not enough homes are being built. More buyers chasing the same limited supply typically means one thing—higher prices.
