What this means
- Assessed 315% above the median other congregate housing (includes non-transient shared living arrangements) in Boston ($747,011, 966 parcels).
- The last deed was recorded for a nominal sum: a transfer between family members, into a trust or a similar non-market sale. It says nothing about the market value.
- A tier-classified site is a release still being cleaned up under the Massachusetts Contingency Plan; the MassDEP file shows the stage reached.
