- Connecticut taxes property at 70% of its appraised market value: the assessment $510,720 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 sale price is 40% above the appraisal.
- Built before 1978: lead paint may be present; Connecticut law requires disclosure to a buyer or tenant.
