• Pending home sales fell 7.3% in September, reversing August's 0.3% gain, with the index dropping to 66.0, down 11.3% year-over-year.
  • All four regions saw declines, led by the West (-9.2%) and South (-8.2%), as mortgage rates near 7.4% squeeze affordability.
  • The drop signals weaker completed sales in the coming months, with broader economic implications for housing-related businesses.

Sharp Reversal

U.S. pending home sales plunged 7.3% in September, reversing a modest 0.3% gain in August, according to the National Association of Realtors. The Pending Home Sales Index, which tracks signed contracts for existing single-family homes, condominiums, and co-ops, fell to 66.0—a record low—and was down 11.3% from a year earlier. All four regions weakened, with the West and South posting the steepest declines of 9.2% and 8.2%, respectively. The data, released Friday, underscores a sharp deterioration in housing demand as rising mortgage rates sideline buyers.

Mortgage Rates Bite

The primary culprit is the relentless rise in borrowing costs. Freddie Mac (FMCC)'s latest survey puts the average 30-year fixed mortgage rate at 7.40%, up from 6.27% a year ago and the highest since November 2023. "The effect on household budgets is substantial," said Lawrence Yun, NAR's chief economist, in a statement. "Higher financing costs can overwhelm improvements in buyers' negotiating power." Indeed, a recent Realtor.com (NWSA) analysis noted that while the market has shifted in buyers' favor, affordability remains stretched. The rise in rates from 5.98% in late February to 7.40% adds roughly $376 a month in principal-and-interest payments on a $400,000 mortgage, according to Associated Press estimates.

Pipeline Pressure

The decline in pending sales is a leading indicator for completed transactions, which typically lag signings by one to two months. September's weakness suggests October and November closings will be soft, pressuring revenue for brokers, mortgage originators, title insurers, and movers. Redfin (RDFN) data already show that 14.5% of homes under contract fell out of contract in September—the highest share outside the early pandemic period—signaling that even signed deals are increasingly fragile. "The housing market is in a deep freeze," said one industry analyst, who requested anonymity to speak candidly. "Without a meaningful drop in rates, we're unlikely to see a sustained recovery."

Broader Economic Ripples

The housing slowdown comes amid a backdrop of elevated inflation and geopolitical tensions. The 10-year Treasury yield, which mortgage rates tend to track, stood at about 5.10% on October 15, up from 3.97% before the U.S.-Iran conflict began, according to AP. That link underscores how global events transmit to Main Street borrowing costs. While the Federal Reserve has signaled a pause in rate hikes, mortgage rates remain stubbornly high, reflecting inflation expectations and bond market volatility. The NAR release did not directly address these macro factors, but Yun has repeatedly cited rates as the key constraint on housing activity.

Looking Ahead

The September plunge marks a deterioration within an already prolonged slump. Existing-home sales have been stuck near a 30-year low, and pending signings were already running about 30% below pre-pandemic levels in August. The key question is whether mortgage rates ease enough to restore purchasing power. Realtor.com's analysis suggests that even with more buyer leverage, affordability remains a hurdle. For now, the data point to weaker transaction activity rather than a nationwide price crash. But with cancellations rising and inventory thin, the housing market's path forward hinges on financing costs. As one NAR spokesperson put it, "Until rates come down, we expect continued volatility in signed contracts."
