What this means
- Connecticut taxes property at 70% of its appraised market value: the assessment $866,310 times the town mill rate gives the yearly tax.
- Plainfield last revalued in 2026. 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.
