A new real estate listing for the mansion is asking for $3,995,000. It is described as eco-friendly and about 10,000 square feet.
Kennedy killed herself by hanging in a separate structure on the property in May.
Her estate had been estimated at nearly $2.1 million, including up to $2 million for her interest in the Bedford home she shared with her estranged husband, according to court papers.
The couple’s eldest son, Conor, and family friend and attorney Faith Miller are the estate’s administrators.
Mary Kennedy’s suicide followed a lengthy battle with depression and the more recent tumult of seeing her husband win custody of the couple’s four children as he was dating the actress Cheryl Hines.
And the bitterness of the couple’s divorce proceedings has continued since her death, first with a court fight over Mary Kennedy’s body.
Robert Kennedy won that battle and buried his estranged wife at the Kennedy family plot near Hyannis Port, Mass.
Her relatives stayed away from the funeral and held their own memorial service in Manhattan —and were mortified in recent weeks to learn that Mary Kennedy’s body was reburied 700 feet away from Kennedy relatives.
A few weeks after the suicide, a published report revealed Robert Kennedy’s claims in an affidavit during the divorce that his wife had physically abused him, drank alcohol excessively and had threatened suicide within earshot of their children. Her family blasted the claims as lies.
Mary Kennedy left no will and her son’s application offered no details on specific assets she left behind – other than her share of the home in Bedford.
