Tracking 27,905 properties across Newton, Massachusetts — a community where the median home dates to 1930 and the oldest to 1686. Every parcel mapped with building characteristics, environmental exposure, hazard risk, and ownership history assembled from 140+ sources.
Newton is one of the largest and most affluent suburbs in Greater Boston, organized around 13 distinct villages — each with its own character, commercial center, and property profile. The city sits along the Massachusetts Turnpike and the Green Line, providing both highway and transit access to Boston. The housing stock is vast and varied: grand estates in Chestnut Hill and Waban, dense multi-family housing near the Newtonville and West Newton village centers, and everything in between.
The village structure means Newton functions less like a single market than like a collection of related but distinct neighborhoods. Assessed values in Chestnut Hill can be multiples of those in Nonantum, and the housing types, construction eras, and lot sizes vary dramatically between villages. For property professionals, Newton's size and diversity make it one of the most data-intensive markets in Massachusetts — generic city-level statistics are nearly meaningless when the variation between villages is this large. Parcel-level intelligence is the only way to work effectively here.
