What a 50-Year Mortgage Could Mean for Home Buyers

The Trump administration has suggested a big change to U.S. housing policy: allowing 50-year mortgages to help people afford homes.

Usually, mortgages in the U.S. last for 30 years, but with a 50-year mortgage, the loan is spread out over a much longer period.
 

How Would a 50-Year Mortgage Work?


The main idea is that with more years to pay back your loan, your monthly payments become lower.

For example, if you borrow $360,000 to buy a $400,000 house (with 10% down) at a 6.25% interest rate, your monthly payment could be about $250 less with a 50-year mortgage compared to a 30-year one.

This could make buying a home easier for people who struggle to keep up with high monthly costs.
 

The Downsides of a Longer Mortgage


However, having a longer loan comes with important drawbacks:
 
  • You Build Equity More Slowly: In the early years of a mortgage, most payments go toward interest, not paying down the actual loan. With a 50-year mortgage, it will take much longer to actually own more of your home.
  • You Pay Much More in Interest: Over 50 years, you will end up paying a lot more interest. For example, you might pay around $816,000 in interest for a 50-year loan, compared to $438,000 for a 30-year loan. In some estimates, the total interest could be nearly double!
  • Doesn’t Fix the Real Problem: Many experts say the real issue is that there aren’t enough homes. Making loans longer doesn’t increase the number of houses for sale. It could even make prices go up, canceling out the benefit of lower monthly payments.

Some rules might block most 50-year mortgages for now. Changing these rules would require government action.
 

Who Might Benefit?


If you have trouble qualifying for a 30-year loan or can’t afford the higher payments, a 50-year loan could help you buy a home now.

For example, at a 6.5% interest rate, the payment on a 50-year loan could be $2,819 a month, compared to $3,079 for a 30-year loan.

But if you want to own your home outright before retirement, or plan to stay in the home for decades, you might be making payments into your 70s or 80s, and it will take many years before you build up equity.
 

Conclusion


A 50-year mortgage could help some people buy homes by lowering payments, but over time, you’ll pay a lot more and build equity much more slowly.

It’s essential to consider the long-term costs, not just today’s payment, and whether this option aligns with your future plans.
