Tracking 15,647 properties across Arlington, Massachusetts — a community where the median home dates to 1933 and the oldest to 1680. Every parcel mapped with building characteristics, environmental exposure, hazard risk, and ownership history assembled from 140+ sources.
Arlington is a dense inner suburb immediately northwest of Cambridge, with a housing stock that reflects its position on the streetcar lines that extended outward from Boston in the late 19th and early 20th centuries. The town's residential neighborhoods are dominated by two-family and triple-decker homes, Victorian-era singles, and the kind of dense, walkable streetscapes that characterized pre-automobile New England suburbs. Massachusetts Avenue — the same road that runs through Cambridge and into Boston — serves as the town's commercial spine.
The Minuteman Bikeway, which runs through Arlington on the path of the old railroad, has become a significant amenity that affects property values along its route. Arlington's proximity to Cambridge and Boston, combined with its housing density and transit access, puts it in a different market tier than the more suburban Middlesex towns. For property professionals, the older housing stock means building age, condition, and systems are the critical variables — most properties predate 1940, and the range of maintenance and renovation levels within a single block can be enormous.
