How to read this explorer
Estimated market value is calculated from final 2025 Board of Review total assessed value divided by the 10% residential assessment level. This is an assessment-based estimate, not a listing or sale price.
Includes 1,512 single-family tax parcels above $3 million, including non-condominium town and rowhomes. Condos, co-ops and multifamily classes are excluded. There are 270 above $5 million and 55 above $10 million. Thresholds overlap.
All 1,512 parcels match unique official 2025 polygon boundaries. Tax parcels have not been independently reconciled to physical houses. Street addresses are joined by parcel identifier to the official 2025 parcel address records.
