What MassDEP has recorded
No tier-classified 21E site and no Activity and Use Limitation is mapped on this parcel.
What this means
- Assessed 311% above the median residential condominium in Marlborough ($1,361,350, 128 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.
