How to read this map
Maps 2,836 residential tax accounts above $3 million, 996 above $5 million, and 150 above $10 million. These overlapping thresholds count each tax account once; 2110 are condo units. Shared building outlines are not additional homes.
Uses Boston’s official FY2026 total property assessment and the saved MassGIS FY2026 assessments for Chelsea, Revere and Winthrop. All four municipalities were checked; qualifying records in this snapshot are in Boston. Boston’s FY2023 MassGIS assessment attributes are not used for price filters. Assessor values are estimates, not current sale or listing prices.
Includes residential houses, townhomes and individual condo units. Apartments, commercial properties, vacant land and multiple-family classifications are excluded.
Boundary matching uses stable town and tax property IDs. Condo units retain their own IDs and share the underlying lot outline; acreage describes the mapped land, not an apartment or survey.
72 newer condo accounts were matched using Boston’s official FY2026 parcel layer; their values agreed with the saved assessment file.
