Montgomery County, Pennsylvania

Montgomery County, home of the historic Main Line, remains one of the region's most sought-after markets, though activity cooled from its summer pace. In the week ending September 30, 2026, homes spent a median of 23 days on the market, 868 homes sold, and current listings rose to 1,698 from 1,672 the prior week, per Bright MLS data compiled by Rarity Real Estate. Realtor.com's monthly active-listing count for the county was 1,283 in September, up meaningfully from earlier in the year, so buyers have more to choose from than they did last fall.

The most recent published monthly median sale price is $508,750 for August 2026, up about 7.1% from a year earlier (Coldwell Banker Hearthside, Bright MLS data), and Redfin's three-month median through August was about $508,000, up about 8.1%. County medians for September are typically published in mid-October, so these are the latest figures available. Main Line communities like Bryn Mawr and Ardmore continue to trade at a premium near SEPTA regional rail stations, while family-friendly suburbs like Blue Bell and Ambler offer great schools and strong options for buyers.

Major employers include pharmaceutical companies, healthcare systems, and King of Prussia's massive retail and business corridor. With SEPTA regional rail, bus, and major highways, commuting to Philadelphia is convenient from most Montgomery County towns.
