The Sotheby's Concierge Auctions founder and CEO shared more about how the recent auction of "La Dune" went down, as well as key reasons why luxury agents turn to the brand to get a deal done.
The sprawling estate, dubbed La Dune for the sandy dune it sits behind, was owned by the former Canadian art magazine publisher, Louise Blouin, 65, who bought it for $13.5million in the 1990s.
