What this means

Connecticut taxes property at 70% of its appraised market value: the assessment $837,340 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 31% below the median for this use in Darien ($1,216,880, 6,138 parcels).
The last sale price is 42% above the appraisal.
Built before 1978: lead paint may be present; Connecticut law requires disclosure to a buyer or tenant.
