Sep 19, 2026 - High Mortgage Rates Reshape Home Sales

• Mortgage rates are nearing 7%, contributing to slower home sales and more cautious buyers, The Wall Street Journal reports. Sellers increasingly are being advised to price homes realistically, address property-condition issues, and consider concessions such as repair credits or mortgage-rate buydowns to keep deals together. The housing market also faces renewed interest-rate pressure after the Federal Reserve raised its benchmark rate by a quarter percentage point in September, bringing the target range to 3.75% to 4%. Slower transaction activity could reduce demand for pre-purchase home inspections, while greater attention to property condition may make inspections more important to buyers and sellers trying to identify repair needs before closing. Sellers also may seek pre-listing inspections to address defects in advance and strengthen their position in a more competitive housing market.
• According to Realtor.com, active home listings rose 3.6% in August compared with a year earlier to about 1.14 million, while 20.4% of listings had a price reduction. Pending sales turned negative year over year after eight consecutive months of growth, suggesting that additional inventory has not translated into stronger transaction activity. A larger supply of homes for sale expands the pool of properties that could eventually require inspections, but weaker pending sales may limit how many listings advance to completed purchases. More frequent price reductions also indicate sellers are adjusting to softer demand. Inspection firms may benefit if improved affordability draws buyers back into the market, although assignment volumes ultimately depend on whether increased inventory produces more signed contracts and closings.
• The National Association of Realtors reports that US existing-home sales fell 2% in August to a seasonally adjusted annual rate of 3.98 million, the lowest level in 14 months, according to Reuters. Elevated mortgage rates continued to weigh on buyer demand and contributed to weaker transaction activity. Existing-home sales are an important source of work for residential inspection firms because buyers commonly seek information about property condition before completing a purchase. A sustained slowdown in transactions can therefore reduce the number of potential pre-purchase inspection assignments and intensify competition among inspectors for available work. Firms may need to monitor local sales volumes closely, as national weakness can affect markets differently and influence staffing, scheduling, and near-term demand expectations.
• The national median price of a new single-family home was $410,700 in the second quarter, $25,000 below the existing-home median of $435,700, according to analysis of Census Bureau data by the National Association of Home Builders. NAHB says regional and compositional differences help explain the unusual pricing relationship rather than a simple decline in the relative value of new construction. Shifts in the price relationship between new and existing homes can influence which properties attract buyers and ultimately generate inspection assignments. Inspection firms serving both new construction and existing-home transactions may benefit from monitoring changes in sales activity between the two segments, particularly if relative affordability causes buyers to reconsider whether to purchase a newly built or previously owned home.
