The 50-Year Mortgage: What You MUST Know!

Last weekend, President Trump tweeted the idea of creating a 50-year mortgage as a way to help lower payments for Americans who want to buy a home. Federal Housing Finance Agency Director Bill Py called the proposal a complete gamecher. It might sound clever, but it just isn't. Let's look at why stretching debt across half a century would likely be disastrous for home buyers and what history tells us about ideas like this.

While the idea is so far quite light on detail, administration officials are saying that a 50-year mortgage would lower monthly payments and help Americans who are currently priced out of the housing market. The logic is that if you just lengthen the term of a loan, you can reduce the monthly payment. But that simplicity hides a much more complicated reality. Extending mortgages to half a century would alter how lenders price risk, how investors value mortgage back securities, and would require changes to federal law.

US home prices have risen about 45% since 2020, with most of that increase having occurred during the pandemic years when interest rates fell near zero. Today, mortgage rates are at their highest level in 20 years. And you would normally expect that to depress home prices, but instead home prices have barely budged since rates went up. Limited housing supply has kept values elevated, but sales volumes have dropped to their lowest level in decades.

On top of that, the average age of a firsttime buyer has now reached 40. Against that backdrop, a longer loan term might look like a lifeline until you check the fine print. The economics and the politics are unfortunately way more complicated than the headlines suggest. On the bright side, however, this proposal would allow many Americans the opportunity to pass something down to their kids.

Unfortunately, that thing would be a mortgage. The 30-year fixed rate mortgage feels like a permanent feature of American life, but it was born out of crisis. Ben Castleman wrote an excellent history of the US mortgage market a few years ago in the New York Times. He explains that before the Great Depression, home loans were underwritten by banks and not backed by the US government.

They usually had terms of 10 years or less as lenders don't really like making long-term loans. And unlike mortgages today, they were not selfvertising, meaning that borrowers just ...
