These Unpopular Mortgages May Be the Key to Affordable Housing

Can a mortgage product tainted by the financial crisis come back to revive US housing? The answer could reorient the housing market and give the Federal Reserve greater control over consumer spending in the years ahead.

A lack of affordability has hindered housing transactions the past two years, frustrating would-be buyers and, more recently, hammering the stocks of developers. Those waiting for popular 30-year mortgages to sink to what’s considered a reasonable rate — around 5.5% by my estimation — have been repeatedly disappointed. To the surprise of many, loan rates climbed after the Fed began easing monetary policy last year. They have averaged 6.9% since February 2023, according to data from the Mortgage Bankers Association.

Indeed, the mortgage market may be ready for a fundamental reshaping in an world where sticky inflation and hefty government borrowing keep longer-term interest rates elevated.

The outsized concentration of homebuyers in 30-year fixed-rate mortgages is an anomaly. In the two decades prior to the 2008 financial crisis, a fifth of homebuyers, on average, opted for adjustable-rate mortgages, which reset after a few years, deciding based on the difference between short- and longer-term interest rates. But following the crisis and until mid-2022, there was no reason to shop around. Rates on 30-year mortgages were kept ultra-low by an extraordinary and extended period of monetary stimulus. That became the new normal for homebuyers and ARMs went out of favor. They accounted for just 6% of mortgage applications last year.
