Sotheby's International Realty
First listed all the way back in 2007 for $14 million, the mansion has undergone a series of listings and price changes, the highest of which was $17 million in the summer of 2015.
The most recent listing was for $13 million, though it's not clear what the final selling price was.
In 2012, the CEO bought another house in Bridgehampton worth $32.5 million, which is reportedly the reason he elected to let go of this one.
Blankfein bought the property in 1995 and commissioned architect Larry Randolf and builders Men at Work to complete the mansion in 2001. The property has seven bedrooms, five full baths, a heated pool, and tennis courts, according to the listing.
Susan Breitenbach of the Corcoran Group handled the listing as of the sale.
