President Donald Trump recently floated the idea of a 50-year mortgage as a way to lower monthly mortgage payments and make home ownership more affordable.
Although the 50-year mortgage is not a new idea, it has taken on greater meaning in the current housing market. Home prices remain near all-time highs and even though mortgage rates have come down, they’re also much higher than only a few years ago, according to Macrotrends.

A 50-year mortgage would lower monthly payments because loans are spread over a much longer period of time versus the standard 30-year mortgage. But is it a good idea? Not everyone thinks so.
Here are four reasons a 50-year mortgage won’t work, according to real estate experts.
One of the biggest problems cited by experts is that the vast majority of homeowners will never pay off a 50-year mortgage simply because they won’t live long enough.
The median age of first-time homebuyers in 2025 is 40 years old, according to new research from the National Association of Realtors (NAR). That’s the highest it has ever been. Meanwhile, the Centers for Disease Control estimates that the average life expectancy in the U.S. is 78.4 years.

Given those numbers, most homeowners won’t reach the age when they can pay off a 50-year mortgage. Even if they do, they could find themselves in dire financial straits, according to Michael Micheletti, chief communications officer at Unlock Technologies, a provider of home equity agreements.
“A couple in their mid-30s who enter into a 50-year mortgage agreement would be paying this off into their 80s,” Micheletti said. “That is problematic given that the vast majority of homeowners will be well past income-earning years at that point. It’s likely people will not have saved enough to continue making their payments in those years, yet alone have enough money to cover essential living expenses and healthcare costs.”
However, others point out that most homeowners don’t live in their homes for the duration of the mortgage, anyway.
“The 50-year mortgage is not about living in the same house for 50 years. There are other considerations that the entire ecosystem benefits from [such as lower mortgage payments],” said Arie Brish, business/technology executive, real estate investor, author and business professor at St. Edward’s University.
