Montgomery County, Pennsylvania
Montgomery County wraps Philadelphia's northwestern suburbs, running from Lower Merion and Cheltenham on the city line out to Lansdale, Pottstown and the Perkiomen Valley. Corporate offices, life sciences and SEPTA rail access drive the market, and mixed-use redevelopment concentrates in King of Prussia, Conshohocken and Norristown because little greenfield remains, leaving zoning overlays and school attendance zones to decide value.
