Listing & sale history

Every time this exact home has come to market in the MLS data this site tracks. Where a sale closed, the recorded sale price is shown; "asking" marks a price the home was listed at rather than what it sold for.

Public record

From the Darien 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.
