The return of 7% mortgage rates is pushing the US housing market into its deepest freeze in nearly 12 years.

According to data from real estate brokerage Redfin, US pending home sales plunged 4% month-over-month in September, marking the largest single-month drop in more than three years and hitting the lowest level since 2014 (excluding the early COVID-19 pandemic period in 2020). At the same time, active listings rose to their highest level since March 2020. Pending sales declined across all 50 major metropolitan areas, the first broad-based pullback since September 2023.

The destructive force of the rate shock has spread through the entire transaction chain. Redfin data shows that nearly one in five sellers was forced to cut their asking price in September, and 14.5% of purchase contracts fell through after signing, the highest share on the company's record, reflecting a sharp deterioration in buyer confidence. Redfin Chief Economist Daryl Fairweather said:

"Sentiment in the real estate industry has shifted significantly. With rates rising this much, fewer people can afford to buy, and sales are bound to decline."

Rates Jump Over 70 Basis Points, Borrowing Costs Hit Near Three-Year High

The trigger for this round of shock was the rapid jump in mortgage rates. According to data from mortgage agency Freddie Mac, the average 30-year fixed mortgage rate soared from 6.66% at the end of August to 7.4% on October 8, an increase of more than 70 basis points and the highest level in nearly three years, more than one percentage point above a year earlier.

The sharp climb in rates over just a few weeks quickly extinguished buying interest that had been rekindled by an earlier brief decline in rates. Analysts noted that the September rate shock has suppressed housing demand to levels last seen after the end of the 2007-2012 foreclosure crisis, exposing the fragility that has accumulated in the market after years of substantial price gains.

This housing cooldown is not evenly distributed, with clear regional divergence. The Northeast and Midwest, where supply remains relatively tight, have seen some support for prices; while some cities in the Sun Belt face the dual pressures of weak demand and falling prices.

The steepest declines are concentrated on the West Coast. Pending sales in Seattle plummeted 24.4% year-over-year, leading all major metropolitan areas nationwide, as high borrowing costs compounded with a slowdown in the local tech industry job market. The city's median home sale price also fell 4.4%, likewise the largest decline in the country.

The Southern California market is also under clear pressure. Redfin data shows that pending home sales in Los Angeles, San Diego and Anaheim all recorded declines of more than 15%. Redfin noted that Southern California properties "rank among the most expensive in the nation, so rising rates hit them especially hard."

Supply-Demand Balance Tilts, Seller Pressure Mounts

Even as demand contracts sharply, the supply side of the market is quietly building up. Listings have risen to their highest since March 2020, and sellers' bargaining power has weakened markedly. Nearly one in five sellers proactively cut their asking price in September, while the 14.5% contract fallout rate not only set a record for Redfin but also means that a large number of transactions already in process are collapsing midway, further dragging down actual sales volume.

This reversal in the supply-demand landscape signals that the balance of market power is shifting from sellers to buyers, but under a high-rate environment, buyers' actual purchasing power is also severely compressed, making it difficult to form effective demand absorption in the short term.

The current market predicament is the result of multiple overlapping factors: years of sustained and substantial home price increases have severely damaged affordability, and the renewed jump in rates has become the final straw for marginal buyers. Daryl Fairweather's assessment cuts to the core — with rates running at elevated levels, affordability issues will continue to constrain sales volume, and the housing market is unlikely to see any meaningful recovery in the near term.
