Public record

From the Westport assessor's public property record. These figures describe the property as the town has it on file and can differ from the listing — a finished basement or an addition may not be reflected in the assessor's living area.

Recorded sales

Deed transfers on file with the Westport land records, newest first. These are recordings rather than MLS sales, so they include transfers that were never listed. Nominal and $0 transfers (estate, trust and family conveyances) are excluded.
