Robert Miller, a Palm Beach real estate investor and marina owner, bought a home on the island for $25 million.
The home sits within the Mar-a-Lago Security Zone, a stretch of the island that falls under Secret Service protection when President Donald Trump is in town.
Records show Miller and his wife Linnette Miller bought the house at 143 Clarendon Avenue from Marcia and William Rickman Jr. The Millers financed the purchase with a $14 million loan from Taylor Made Lending, according to property records. Carole and Brett Koeppel with Sotheby’s International Realty had the listing, and Carole Koeppel brought the buyer.
Miller is the owner of Jupiter Pointe Club & Marina in Tequesta, where he also heads MLR Management LLC.
He and his son Myron “Mosie” Miller frequently partner on real estate investments in Palm Beach County. In 2023, Mosie Miller sold BET co-founder Robert Johnson a Palm Beach Gardens mansion for $20 million. A few months later, he sold an oceanfront mansion in Palm Beach for $68.1 million.
In 2021, Robert and Linnette Miller sold a lakefront mansion to spec developer Todd Glaser for $23.8 million. Glaser flipped it a few months later for $31.7 million. Records show the couple also owns the 1.3-acre Bear’s Club estate at 150 Bear’s Club Drive in Jupiter, which they bought for $10.7 million in 2021.
The Rickmans bought the 0.6-acre Clarendon Avenue home for $9 million in 2008, according to property records. The 5,800-square-foot house has five bedrooms, four bathrooms, one half-bathroom, a pool and separate staff quarters, records and the listing show. It was built in 1924 by celebrated Palm Beach architect Maurice Fatio.
Clarendon Avenue is the upper limit of the Mar-a-Lago Security Zone, which has emerged as a hotbed of luxury real estate deals since Trump’s 2024 electoral victory. Seven sales totaling $118.3 million closed in the months following his election, with agents touting security and proximity to power as perks of the neighborhood.
Dubbed “Villa Dolce,” the Rickmans sold the home for the asking price after just three months on the market.
William Rickman Jr. is a scion of the Maryland real estate family that owned and operated the racetrack and casino Delaware Park for decades. He sold the track, first developed by William du Pont Jr. in the 1930s, to private equity firm Clairvest and Rubico Gaming in 2021, according to published reports. The Rickmans also own the oceanfront estate at 1055 North Ocean Boulevard, a 10,200-square-foot mansion they bought for $13.1 million in 2016, according to property records. Sources told The Real Deal the half-acre property is among those targeted by billionaire Excel creator Charles Simonyi as he assembled a sprawling estate on the island.
