Even after selling Circus Circus Las Vegas and negotiating a sale-leaseback of the Bellagio, MGM Resorts International said Wednesday the company is not done shopping available real estate. During the company’s third quarter earnings call, MGM Chairman and CEO Jim Murren said a deal for the flagship MGM Grand Las Vegas could be announced before the end of the year. The model is the company’s sale and leaseback of the Bellagio to Blackstone Real Estate Income Trust. “The Bellagio real-estate transaction represents more to us than a smart financial deal,” Murren said during a question and answer session with analysts. “It provides a likely blueprint for the future.”
