The quiet housing market flip nobody is talking about
After years of being frozen in place, the U.S. housing market may finally be showing signs of thawing.
A little-noticed shift is underway: for the first time in years, more American homeowners now carry mortgages with rates above 6% than those with ultra-low rates below 3%. That change is beginning to loosen the so-called “golden handcuffs” that have kept millions of homeowners from selling.
By 2025, 21.2% of U.S. mortgage holders had rates above 6%, surpassing the share of sub-3% mortgages, according to data compiled by Reventure Consulting’s Nick Gerli. It’s the highest share of 6%-plus mortgages since 2015.
The shift marks a clear regime flip from the pandemic era, when millions of homeowners locked in historically low mortgage rates. When interest rates surged in 2023, those ultra-cheap loans became a powerful incentive to stay put, sharply restricting housing supply and driving inventory to historic lows.
Now, that lock-in effect is gradually weakening.
As more homeowners carry mortgages closer to prevailing market rates, the financial penalty of selling — giving up a once-in-a-generation interest rate — has diminished. In practical terms, moving no longer requires doubling a mortgage rate, making the decision to sell less financially punishing.
That shift matters because housing supply has been the market’s biggest constraint. A larger share of homeowners being willing to sell opens the door to higher listings and slowly improving inventory, even if mortgage rates remain elevated.
“This is happening because even in today’s depressed sales and refinance environment, each year about 5-6 million Americans take out a new mortgage,” Gerli wrote.
While the shift won’t produce a flood of homes overnight, it does signal that one of the strongest forces suppressing housing supply since the pandemic is beginning to fade.
More Americans are feeling the strain of today’s housing environment
While the easing of the mortgage rate lock-in effect could bring some long-term relief to the housing market, it doesn’t mean conditions are improving for everyone.
For many homeowners, particularly recent buyers, today’s higher interest rates are introducing new financial stress.
A November report from Intercontinental Exchange (ICE) found that nearly 900,000 U.S. homeowners were now “underwater” on their mortgages, meaning they owe more on their loan than their home is currently worth.
The problem is most pronounced in formerly red-hot Sun Belt markets, where pandemic-era migration and rapid price appreciation pushed home values sharply higher in a short period of time.
As price growth has cooled, and in some cases reversed, that cushion of equity has begun to erode. Markets such as Austin, Texas, which saw some of the fastest gains during the pandemic, have reported home price declines, increasing the risk for recent buyers.
According to Amy Walden, head of mortgage and housing research at ICE, borrowers who purchased in recent years with smaller down payments face the greatest vulnerability, as even modest price declines can push them into negative equity.
