Trump Jr. and Guilfoyle are under contract to buy the seven-bedroom, 12-bathroom mansion at 492 Mariner Drive, which is on the market for $11 million. And Guilfoyle, alone, plans to buy the estate next door at 494 Mariner Drive, which is asking $9.5 million, according to the Palm Beach Post. Peter Moore, general manager of Admirals Cove’s homeowners association, told the newspaper that about 30 residents have reached out with their concerns. “I believe their membership would bring undesirable notoriety to the club, harm our reputation and have the potential for creating disharmony,” one resident said.
