What this means
- Connecticut taxes property at 70% of its appraised market value: the assessment $1,753,920 times the town mill rate gives the yearly tax.
- Darien last revalued in 2023. Towns revalue every five years; between two revaluations the appraisal stays the same even if the market moves.
- Assessed 44% above the median for this use in Darien ($1,216,880, 6,138 parcels).
- The last sale price is 20% above the appraisal.
- Built before 1978: lead paint may be present; Connecticut law requires disclosure to a buyer or tenant.
