History
The property of Maison de L'Amitié was formerly owned by Dun & Bradstreet family member Robert Dun Douglass. It was sold to tycoon Harrison Williams in 1930. Owner Jayne Wrightsman sold the house on May 1, 1985, for $10 million to Les Wexner. Three years later, on May 27, 1988, it was sold to Massachusetts nursing home magnate Abraham "Abe" D. Gosman for $12,089,500. Gosman built the mansion on the property and named it Maison de L'Amitié''. On July 30, 1999, the house was put in the name of his wife, Linda C. Gosman. After Abe Gosman filed for Chapter 7 bankruptcy liquidation in 2003, the property went up for auction in 2004.

On January 7, 2005, entrepreneur Donald Trump bought the home for $41.35 million outbidding Jeffrey Epstein. Trump listed the home in early 2006 for $125 million. An employee of Trump Properties in Florida said that Trump had spent $25 million on renovations, while Trump himself claimed to have only spent around $3 million renovating the house. In March 2008, after cycling through several real estate brokers, Trump lowered the asking price to $100 million. On July 16, 2008, Trump sold the home to Russian billionaire Dmitry Rybolovlev through his County Road Property LLC, for $95 million. At the time it was the most expensive residential property sale to ever occur in the United States. 

Rybolovlev purchased the home with a trust. During divorce proceedings for the Rybolovlevs, Dmitry denied direct or indirect ownership of the house in a 2011 deposition. According to him, the real owner of the mansion was a family trust established for the financial future of his two daughters. The house remained empty since the purchase. Due to years of divorce proceedings, in which all the property of Rybolovlev, including the house, was arrested, Maison de L'Amitié could not be used. 

In 2013, a Palm Beach County appraisal of the house valued it at $59.8 million. In 2013, the media reported about Rybolovlev's plans to demolish the house and divide it into 3 lots for sale. He described it as an opportunity to divide the land into smaller plots. A plan to demolish the residence was approved by the Palm Beach architectural commission in April 2016. The Palm Beach Town Council approved a proposal to subdivide the property into three parcels of around two acres each. 

One parcel of  sold for $34.34 million in November 2016. The other two were sold for $37 million in October 2017, and $37.29 million in July 2019. All three lots were sold through the brokerage services of Lawrence Moens, an agent with Lawrence A. Moens Associates. Moens was also involved in the sale of Maison de L'Amitié when it was sold by Donald Trump. All three lots amounted to a total of $108.2 million, which is roughly $13 million more than what Rybolovlev paid for the property in 2008.
