Home value figures are sourced directly from the Zillow Home Value Index (ZHVI), the city-level smoothed seasonally-adjusted series covering all home types (single-family, condo, co-op). Rent figures are sourced directly from the Zillow Observed Rent Index (ZORI), the city-level smoothed series covering all homes including multifamily.
Data reflects published values as of April 30, 2026. Of 161 towns in the 35-mile radius: 104 have both ZHVI and ZORI coverage, 54 have ZHVI only (no rent index published), and 3 have neither.

ZHVI is a smoothed measure of the typical home value, calibrated to the 35th-to-65th percentile band of all homes in a given region. It is not a median sale price or a transaction index; it is derived from Zillow's home-value model aggregated across all homes in the area.
ZORI reflects current asking rents on listed units, weighted to the rental stock. It is what someone moving in today would be quoted, not what existing long-term tenants pay (which typically runs 15-25% lower for tenants in place for several years). ZORI is also a blended figure across studio, 1BR, 2BR, and 3BR+ rentals weighted to the local rental mix.
Year-over-year change is computed from the April 2026 ZHVI value against the April 2025 ZHVI value for the same town. Towns missing from the Zillow ZHVI file display no YoY change. Geometry is simplified MassGIS municipal boundaries.
This atlas is an independent reference. It is not legal, financial, or investment advice. ZHVI and ZORI are statistical indexes of typical regional values, not specific transactions; individual homes vary materially from these aggregates.
The atlas does not derive synthetic values for missing towns or interpolate from neighbors. Towns absent from Zillow's source data are marked NO DATA rather than filled with estimated values.
If you find a value materially wrong, the most helpful thing is to point to a public source that disagrees.
