The Great Freeze

The numbers trace a brutal arc. Existing home sales — which represent roughly 85% of all home transactions in the United States — averaged around 5.3 million per year from 2014 to 2019, a healthy if unremarkable clip. Then came the pandemic. Sales surged to 5.64 million in 2020 and 6.12 million in 2021, driven by COVID-era demand for space, remote work flexibility, and the lowest mortgage rates in history. The frenzy was unmistakable: homes sold in an average of 17 days, bidding wars became the norm, and buyers waived inspections just to get an offer accepted.

The 2022 rate shock ended the party with a jolt. As rates doubled from 3.5% to 7%, existing sales plunged to 5.03 million in 2022, then 4.09 million in 2023, and 4.06 million in 2024 — the weakest pace since Bill Clinton’s first term. The 38% decline from 2021 to 2024 was steeper than the crash of 2007–2008, when sales fell 33% from their bubble peak. But this time, the cause was entirely different. In 2008, sales fell because buyers couldn’t borrow. In 2023, sales fell because sellers wouldn’t sell.

The distinction matters enormously. A demand-driven downturn clears itself: prices fall, affordability improves, and buyers return. A supply-driven freeze is self-reinforcing: fewer listings mean fewer transactions, which means less inventory, which keeps prices high, which keeps buyers priced out, which reduces demand further. The American housing market has been stuck in this loop for three years. By 2025, sales edged up to roughly 4.35 million — a modest improvement but still 29% below the 2021 pace, and below the 2015–2019 average. The freeze is thawing, but glacially.

The lock-in effect is the defining feature of this housing cycle. It works like this: a homeowner who refinanced to a 2.9% rate in 2021 pays roughly $1,200 per month on a $280,000 mortgage. If they sell and buy a comparable home at today’s $413,000 median and 6.5% rate, their payment jumps to $2,090 — a 74% increase for the same standard of living. The only way to avoid the payment shock is to use a large chunk of their home equity as a down payment, which reduces their liquid savings. For most families, the math doesn’t work.

The Federal Housing Finance Agency estimates that over 80% of outstanding mortgages have rates below 5%, and roughly 60% are below 4%. These are not just numbers on a spreadsheet — each one represents a family that has a powerful financial incentive to stay in their current home. The homeowner with a 3% rate on $300,000 is saving $633 per month compared to the current market rate. Over 25 years, that differential is worth nearly $190,000 in present value. Selling the house means surrendering that asset. Few families will do it voluntarily.

The lock-in effect is not equally distributed. Younger homeowners who bought in 2020–2021 with small down payments are the most locked in — they have less equity to use and larger mortgages to refinance. Older homeowners and retirees who are downsizing may actually benefit from the sale (pocketing equity to buy a smaller home with cash), but even they face the psychological pain of losing a low rate. The result is a market where everyone has a reason not to sell. As Lawrence Yun, NAR’s chief economist, has noted, the lock-in effect has removed an estimated 1.5 to 2 million listings per year from the market — homes that would normally be for sale but aren’t.

The South dominates American housing by sheer volume. At 1.85 million sales in 2025, it accounts for 43% of all existing home transactions — nearly as many as the Midwest and Northeast combined. Texas alone sells more homes annually than the entire Northeast region. The South’s dominance reflects both population growth (the Sun Belt migration) and relative affordability: the median home in the South costs $363,000, compared to $502,000 in the Northeast and $619,000 in the West.

The West suffered the steepest decline: sales fell 43% from 2021 to 2025. California, where the median home tops $800,000, has been particularly frozen. The lock-in effect is most extreme where prices are highest, because the gap between the existing mortgage and a new one is largest. A Bay Area homeowner with a 3% rate on a $700,000 mortgage saves over $2,000 per month compared to current rates. That’s not a rate differential — it’s a lifestyle differential. They’re not selling.

The Northeast, already the smallest market by volume, fell 37%. High prices, dense urban markets with limited turnover, and an aging homeowner population all contributed. The Midwest, where prices are most affordable, held up slightly better with a 30% decline. But “better” is relative: even the Midwest is selling 30% fewer homes than it was three years ago. The freeze is national. It just bites harder where prices are highest.

The lock-in effect will eventually fade. Mortgages mature, families grow, divorces happen, jobs relocate, and people die. Life events force sales regardless of interest rates. The question is how long the thaw takes. Economists at the Federal Reserve Bank of Dallas estimate that the lock-in effect suppresses roughly 1.3 million sales per year at current rate levels. If rates decline to 5.5%, the suppression drops to about 700,000. At 4.5%, the effect largely disappears. But rates are not heading to 4.5% anytime soon.

The more likely path is a slow normalization over 5–7 years. Each year, roughly 5% of homeowners sell for non-financial reasons (death, divorce, job transfer, major life change). Over time, these life-event sales will replenish inventory. New construction will add supply — builders started roughly 1.36 million homes in 2025, as Episode 6 explores. And as home equity builds (prices continue to rise), some owners will feel wealthy enough to absorb the rate penalty.

But the American housing market of 2019 — 5.3 million annual sales, reasonable inventory, and buyers who could browse for months before making an offer — is not coming back quickly. The lock-in effect has created a structural change in how the market functions. Turnover is lower, holding periods are longer, and the market is less liquid than at any point in the modern era. Real estate agents, mortgage brokers, title companies, and moving companies that staffed up for the 2020–2021 boom have been devastated. The National Association of Realtors reported that agent membership fell 4% in 2024, the largest decline in 15 years.
