       “Rarely does a home of this size and scale exist on the water, let alone come to market in the Hamptons,” said Preston Kaye, co-founder of Hedgerow Exclusive Properties.

       The mansion has reportedly never before been available for purchase on the open market, but was part of a 20-acre off-market deal in 2021, according to Mansion Global.

       “The property was the crown jewel of a family compound that was created over a 20-year period,” Mr Kaye told it.

       “The new buyer saw this as an opportunity to obtain both a waterfront and agricultural compound, with the intention to spin off the largest of the four parcels.”
