Philadelphia search is several markets stitched together. Center City and University City are towers, condos, hospitals and campuses. Around them runs a grid of neighborhoods, from South Philly to Fishtown to Manayunk, where people say row home and search by neighborhood name.
West of the city sit the Main Line and King of Prussia, with stone houses, office parks and a retail hub. East across the Delaware, Cherry Hill and South Jersey follow New Jersey rules and New Jersey habits.
Pennsylvania and New Jersey each license brokers and contractors separately, so a license line has to name the state it belongs to. Zillow, Bright MLS and Realtor.com own the searches for homes for sale.
Almost everything else is open to a local firm.
