Robert Miller, a real estate investor and marina owner based in Palm Beach, has purchased a home on the island for $25 million. The property is located at 143 Clarendon Avenue within the Mar-a-Lago Security Zone, an area that receives Secret Service protection when President Donald Trump is present.
According to property records, Miller and his wife Linnette acquired the house from Marcia and William Rickman Jr., financing the purchase with a $14 million loan from Taylor Made Lending. Carole and Brett Koeppel of Sotheby’s International Realty handled the listing, with Carole Koeppel representing the buyer.
Miller owns Jupiter Pointe Club & Marina in Tequesta and leads MLR Management LLC. He often invests in real estate with his son Myron “Mosie” Miller. In 2023, Mosie Miller sold a mansion in Palm Beach Gardens to BET co-founder Robert Johnson for $20 million. Later that year, he sold an oceanfront mansion in Palm Beach for $68.1 million.
In 2021, Robert and Linnette Miller sold a lakefront mansion to developer Todd Glaser for $23.8 million; Glaser later resold it for $31.7 million. The Millers also own a 1.3-acre estate at Bear’s Club Drive in Jupiter, which they bought for $10.7 million in 2021.
The sellers, Marcia and William Rickman Jr., had purchased the Clarendon Avenue home for $9 million in 2008. The residence spans 5,800 square feet with five bedrooms, four bathrooms, one half-bathroom, a pool, and separate staff quarters. Built in 1924 by architect Maurice Fatio, it was marketed as “Villa Dolce” and sold at its asking price after three months on the market.
Clarendon Avenue marks the upper boundary of the Mar-a-Lago Security Zone—a neighborhood that has seen increased luxury real estate activity since Trump’s victory in the 2024 election. Seven sales totaling $118.3 million have closed there following his election win; agents highlight security measures and proximity to political power as key attractions.
William Rickman Jr., part of a Maryland family known for owning Delaware Park racetrack and casino for decades before selling it to Clairvest and Rubico Gaming in 2021 according to published reports, also owns an oceanfront estate at 1055 North Ocean Boulevard purchased for $13.1 million in 2016. Sources indicate this property is among those sought by billionaire Charles Simonyi as he expands his holdings on Palm Beach Island.
