Prices are estimates calibrated to the Zillow Home Value Index and Redfin; tax rates are FY2026 residential rates and the bill applies that rate to the town’s own median 4BR estimate; commutes take the rail leg from the MBTA timetable and still model the drive; rents are HUD FY2026 Small Area Fair Market Rents. School tiers are editorial and shown next to the state’s own MCAS figures. Data last reviewed — see the methodology. This comparison never uses demographics as an input.
