Last week, President Trump stirred up controversy by suggesting a 50-year fixed mortgage. Many people, even some of his supporters, didn’t like the idea. They argued this type of mortgage would keep Americans in debt for life, essentially turning homeowners into lifelong renters from banks. Critics pointed out that it could lead to massive interest payments, leaving borrowers stuck with high costs and little equity over time.
Rep. Marjorie Taylor Greene summed up these concerns, saying, “In debt forever, in debt for life!” Others voiced similar sentiments, fearing it would create a cycle of generational debt.
The backlash was loud enough that reports claimed the White House was upset with the official who presented the idea. But is a 50-year mortgage really that outrageous?
Interestingly, financial experts have mixed feelings. John Campbell, an economist at Harvard, suggests it might not be that crazy. Eric Zwick from the University of Chicago agrees, noting it’s not much different from a 30-year mortgage.
Most people don’t keep their mortgages for the full term. In fact, research shows that typical American homeowners stay in one place for less than 12 years. Many sell their homes or refinance before the mortgage ends.
Daryl Fairweather, chief economist at Redfin, mentioned that if a 50-year mortgage existed, most people might start with it but likely refinance later. This means the longer duration wouldn’t necessarily trap them. In fact, it might offer lower monthly payments, making homes seem more affordable upfront.
Zwick pointed out that affordability is key in the housing market. A longer mortgage can lower monthly costs, which could help more people buy homes. However, the trade-off is inevitable: borrowers would pay more interest over time and build equity slowly.
The 30-year mortgage has become a staple in America. Over 90% of mortgage holders have one. This preference is partly due to a unique aspect of the U.S. mortgage market. Unlike in countries like the UK, Americans generally can’t transfer their mortgages when they sell their homes.
Long-term fixed mortgages offer predictable payments, which many find comforting. However, they can also be risky. If housing prices drop, homeowners might owe more than their property is worth, a situation known as going “underwater.” Economists warn that this can lead to significant financial strain.
The heavy reliance on fixed-rate mortgages raises broader economic concerns. For instance, if everyone had adjustable-rate mortgages, economic shifts like interest rate decreases could stimulate spending more effectively. But in the current system, borrowers are shielded from these changes.
Harvard economist John Campbell highlighted another issue: financial literacy. Many people don’t know when to refinance. Minority borrowers often refinance less frequently than white borrowers, resulting in higher interest rates for them. This situation can exacerbate financial inequalities.
There’s also a phenomenon known as “lock-in,” where homeowners with low-interest rates feel reluctant to sell, leading to stagnant housing markets. This could explain why U.S. home prices have remained high even as interest rates increased.
So, what’s the real solution to housing affordability? Experts agree it’s not simply about introducing new mortgage options. We need to increase the supply of affordable homes. Without more houses, making it easier for buyers just leads to bidding wars that push prices higher.
In conclusion, while a 50-year mortgage might help some, it won’t fix the root problems in the housing market. More education on financial options and a focus on building homes are much needed.
