The Platinum Triangle’s powerhouse brokerage Hilton & Hyland, t is as synonymous, in the finer zip codes across Los Angeles with high-end real estate. Rick Hilton has negotiated for untold numbers of deep-pocketed buyers and sellers — he represented both buyer and seller in the landmark $85 million sale of the Spelling estate in Holmby Hills to Formula One racing heiress Petra Ecclestone, who has since sold the house for $120 million — he’s also developed some choice tracts of land around town, including the guard-gated Brentwood Country Estates enclave where some of the homeowners include Arnold Schwarzenegger and sitcom producer Kevin Bright. His most recent project has just hit the market at $55 million. Tax records show the property was purchased by a corporate concern linked to Hilton in July 2016 for $9,262,500, well below the $11.5 million asking price, from apparel mogul Treivush Menachem. While Hilton and his team laid the groundwork, worked on the design, secured the necessary permits, and, per tax records, took out a $26 million loan to finance the construction of a new residence.
