The U.S. housing market suffered another setback in October as existing-home sales fell to their lowest level in more than 16 years, highlighting the growing impact of elevated mortgage rates and persistent affordability challenges on American households.
According to the National Association of Realtors (NAR), existing-home sales declined 5.5% from September to a seasonally adjusted annual rate of 3.75 million units. Transactions were down 8.8% compared with October 2025, marking the weakest sales pace since August 2010.
The slowdown comes as mortgage rates continue to climb, making homeownership increasingly expensive for prospective buyers already facing elevated property prices.
The average 30-year fixed mortgage rate reached 7.33% in October, up from 6.86% in September and 6.25% a year earlier, according to Freddie Mac data cited by NAR.
For buyers financing a $400,000 mortgage, that increase from last year’s rate translates into approximately $280 more in monthly principal and interest payments, creating another financial obstacle for households considering a purchase.
Despite weakening demand, home prices have remained remarkably resilient.
The national median existing-home sales price reached $416,700 in October, representing a 0.4% increase from the previous year. It marked the 40th consecutive month of annual price increases, illustrating the continuing disconnect between housing affordability and property valuations.
However, signs of improving inventory conditions are emerging.
The number of homes available for sale increased to 1.59 million, up 4.6% from a year earlier. That represents a 5.1-month supply at the current sales pace, compared with 4.4 months in October 2025.
More available inventory could eventually provide buyers with additional negotiating power, particularly in markets where sellers have become accustomed to rapid transactions and rising prices.
Regional data showed that the weakness was widespread.
Existing-home sales declined 9.7% in the West, 6.5% in the South, and 3.2% in the Midwest. Sales remained unchanged in the Northeast.
First-time buyers accounted for just 29% of transactions, down from 32% a year earlier, underscoring the challenges facing households attempting to enter the housing market.
The implications extend beyond real estate.
Housing transactions generate economic activity across mortgage lending, brokerage services, home improvement, furniture, appliances, and other consumer industries. Fewer transactions can reduce spending across these categories, potentially affecting companies that depend on residential turnover.
Building materials suppliers and installation contractors also face a complicated environment as higher financing costs influence construction activity and renovation decisions.
The slowdown helps explain why some construction-related companies are seeking greater exposure to commercial and industrial markets.
Installed Building Products (NYSE: IBP), for example, recently announced its acquisition of Old Dominion Group, expanding its commercial and industrial installation capabilities while reducing its relative dependence on residential construction.
The transaction illustrates how businesses exposed to housing cycles are attempting to diversify into infrastructure, data centers, and other construction markets.
For investors, the housing slowdown also creates a broader question about the direction of interest rates.
If inflation remains elevated and borrowing costs stay high, housing affordability could remain under pressure. Conversely, declining mortgage rates could release pent-up demand from buyers who have postponed purchases.
NAR has indicated that substantial potential demand remains, particularly among households waiting for financing conditions to improve.
For now, October’s report highlights an economy in which housing remains a significant source of financial strain.
Whether the market begins recovering will depend on mortgage rates, household incomes, available inventory, and the willingness of sellers to adjust expectations.
Until those conditions improve, housing-related businesses may continue facing a challenging operating environment, even as opportunities emerge for companies positioned to navigate the slowdown.
