Brownfield inventory
- Winchester Arms, 270 Mansfield Street — program: NONE
Within about 500 m (a third of a mile): 5 sites of the state brownfield inventory. Brownfields in New Haven.
What this means
- Connecticut taxes property at 70% of its appraised market value: the assessment $244,370 times the town mill rate gives the yearly tax.
- New Haven last revalued in 2021. Towns revalue every five years; between two revaluations the appraisal stays the same even if the market moves.
- The last deed was recorded for a nominal sum: a transfer between family members, into a trust or similar. It says nothing about the market value.
