WEST CHESTER, PA — Chester County home prices continued to rise in August even as the national housing market weakened, with constrained local inventory supporting prices and competition while mortgage costs kept affordability under pressure.
The county’s median sale price ranged from about $565,000 to $620,000, up an estimated 2% to 4% from a year earlier. Nationally, the typical U.S. home value rose 1.3% to $369,678, according to Zillow’s August Market Report.
That puts Chester County’s median price roughly $195,000 to $250,000 above Zillow’s national home-value measure, while its annual price growth also outpaced the national rate.
The divergence came as U.S. sales softened. Zillow estimated 339,927 homes sold nationally in August, down 0.6% from a year earlier and 10.7% from July. Newly pending listings fell 2.6% annually, pointing to weaker closings ahead.
Chester County remained considerably tighter. Available inventory stood at roughly 1.5 to 2 months of supply, compared with the four to six months generally associated with a balanced market. Existing homeowners with mortgages below 4% continued to limit resale supply, while new construction has not added enough homes to offset demand.
The countywide sale-to-list ratio remained near 101%, with move-in-ready properties in sought-after school districts frequently going under contract within about 10 to 18 days. Nationally, homes took a median 27 days to go pending in August.
Zillow reported 1.41 million homes for sale nationwide, 3% more than a year earlier. The share of listings with price cuts reached 26.3%, while 29.6% of homes sold above list price in July, the latest month available for that measure.
Chester County’s relative strength varied sharply by geography.
The eastern Main Line market, including Tredyffrin, Easttown, Willistown and Malvern, remained the county’s most supply-constrained segment, with about 1.1 to 1.4 months of inventory. Median prices ranged from roughly $850,000 to more than $1.1 million, while some properties sold at 102% to 104% of asking prices.
The West Chester, Exton, and Downingtown corridor carried median values of roughly $580,000 to $665,000 and 1.5 to 1.8 months of inventory. Homes generally spent 12 to 24 days on the market and sold for about 100% to 102% of list price.
Western Chester County offered substantially lower entry prices and more inventory. Coatesville, Parkesburg, Honey Brook, Atglen and Oxford recorded median prices of about $350,000 to $425,000, with supply of roughly 2.2 to 3 months and market times of 25 to 45 days.
Financing costs continued to constrain buyers across the county. Thirty-year fixed mortgage rates were around the mid-6% range during late summer, putting estimated principal-and-interest payments on a median-priced Chester County home at roughly $2,800 to $3,300 for buyers making a 20% down payment.
After property taxes and insurance, estimated monthly housing costs frequently reached $3,700 to $4,200. Zillow put the monthly mortgage payment on the typical U.S. home at $1,897, including estimated taxes, insurance and maintenance and assuming a 20% down payment.
The pressure is also pushing some prospective buyers toward rentals.
Chester County rents averaged approximately $2,050 to $2,250 a month in August, above Zillow’s national typical rent of $1,948. County occupancy remained around 95%.
West Chester and Phoenixville one-bedroom apartments generally rented for $1,800 to $2,100, while two-bedroom townhomes and higher-priced apartment communities ranged from $2,400 to $2,900. Central Chester County rents generally ran from $2,100 to $2,500, while western communities were lower at about $1,500 to $1,850.
National rents increased 2.5% from a year earlier, nearly twice the 1.3% growth in U.S. home values. Zillow Chief Economist Mischa Fisher attributed the broader shift partly to borrowing costs.
“The combination of weak sales and even weaker pending sales points to a soft close to 2026,” Fisher stated. “There are more homes for sale than a year ago, which is good news for buyers who are ready to move, but until rates ease, many households will likely stay on the sidelines a little longer as renting is still the more affordable substitute.”
Chester County’s August figures point to a different balance: affordability remains a constraint, but limited supply has so far prevented the weakening in demand seen nationally from translating into comparable pressure on local home prices.
