What MassDEP has recorded

No tier-classified 21E site and no Activity and Use Limitation is mapped on this parcel.

Within about 500 m (a third of a mile): 3 active tier-classified 21E sites and 7 sites with an Activity and Use Limitation. All MassDEP sites in Boston.

What this means

Assessed 188% above the median residential condominium in Boston ($1,926,500, 10,170 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.
Built before 1978: the Massachusetts Lead Law applies when a child under six lives there; ask for any lead inspection or letter of compliance.
