Tracking 18,626 properties across Medford, Massachusetts — a community where the median home dates to 1921 and the oldest to 1678. Every parcel mapped with building characteristics, environmental exposure, hazard risk, and ownership history assembled from 140+ sources.
Medford is a dense inner suburb north of Boston and east of Cambridge, with Tufts University occupying a prominent hilltop position. The city's housing stock is dominated by multi-family buildings — triple-deckers and two-families from the late 1800s and early 1900s — with pockets of single-family homes in the Medford Hillside and West Medford neighborhoods. The Mystic River runs through the city, and the Mystic Lakes create waterfront properties in the western sections.
The Green Line Extension, which brought subway service to Medford in recent years, has significantly affected property values and development activity near the new stations. For property professionals, Medford is an urban market where transit access, building condition, and neighborhood position are the key value drivers. The older housing stock means systems age and renovation history are critical assessment factors, and the rapid market changes near the GLX stations make current data particularly important.
