You’ll notice something odd for a supposedly dynamic housing market if you drive through nearly any well-known American suburb today, such as Thousand Oaks in California, Naperville outside of Chicago, or the older subdivisions surrounding Charlotte. The driveways are packed, the lawns are neat, and there are hardly any for-sale signs. People are at home. They simply won’t go.
This is the street-level appearance of a frozen market. Not overly dramatic. Not clearly damaged. Still, in a way that has actual repercussions for anyone attempting to enter, advance, or start over somewhere else. The US housing market has been in an unsatisfactory state for the past three years. It’s a standstill, not a crash, correction, or bubble, and it’s mostly caused by a difference between two figures that most people never thought would be so important: your current mortgage rate and the one you’d have to accept if you moved.

Once the math is presented, it is nearly impossible to dispute. During the pandemic, when the Federal Reserve was keeping mortgage rates at all-time lows and lenders were essentially giving away money, millions of American homeowners locked in mortgage rates below 3%. There is currently a 3.2 percentage point difference between what current homeowners pay each month and what they would pay on a new loan for a comparable property because those rates are currently around 7% for new loans.
That difference corresponds to an extra $700 to $800 in monthly payments for a $400,000 mortgage. It’s not a rounding error. That represents a significant portion of most families’ budgets—a car payment, a grocery bill, etc. Thus, people continue to stay. Rather than moving, they remodel. They put up with the school district they’ve outgrown, the commute, and the small office. The low rate effectively turns into a golden pair of handcuffs, making leaving seem financially unreasonable.
This has wider repercussions than initially thought. Approximately 4.7 million homes are needed in the US, according to the National Association of REALTORS®. That figure has been influenced, at least in part, by the lock-in effect that prevents current inventory from being sold. This is further complicated by research from Justin Katz at Harvard’s Joint Center for Housing Studies: typically, when mortgage rates rise, some homeowners become renters, freeing up supply and driving down prices. That mechanism was short-circuited by the lock-in effect. Even as rates increased, homeowners who would have sold and rented stayed put, keeping supply tight and prices high. It’s a feedback loop that worsened the situation for consumers across nearly all price points.
First-time purchasers suffered the most. When a new buyer entered the market for the majority of the last three years, they had to contend with all-cash offers, investors making large purchases, and a very small pool of inventory. The entry-level market virtually vanished in some cities, including Austin, Phoenix, and areas of the Sun Belt that had experienced frenzied appreciation during the pandemic. During the height of those years, a generation of potential buyers stood by and waited for a window that never seemed to open. The notion that the same low rates that saved current homeowners a substantial amount of money each month also priced an entire cohort out of the market for years makes it difficult to avoid feeling a little uneasy.
As spring 2026 approaches, there are hints that something might be changing. Due in large part to income growth outpacing increases in home prices in many markets, affordability has improved for eight consecutive months. In February, 34% of purchases were made by first-time customers. This figure is noteworthy since first-time customers often initiate the entire chain. When they purchase starter homes, the market finds some circulation, existing owners can advance, and rental inventory becomes less constrained. Only 14% of homes are selling for more than asking, a significant decrease from the wild peaks of bidding wars. Negotiation, a notion that seemed almost antiquated for a few years, has subtly returned, and homes are remaining on the market for longer.
It’s still unclear if this is a seasonal uptick or a true thaw. A homeowner with a 2.75% mortgage rate still has very little financial incentive to trade it for a 6.8% rate, even if they would prefer a different home. This is because mortgage rates haven’t dropped enough to completely eliminate the lock-in effect. It’s possible that the market adjusts gradually, that builders close enough of the gap to provide buyers with genuine options, and that sellers start to accept the new reality and adjust prices accordingly. Another possibility is that rates remain stubbornly high and the freeze lasts for an additional year or two, which would wear down patience but not the underlying math. When the housing market gets this complicated, it usually follows its own timetable instead of anyone else’s.
