The sell-off is the latest move by MGM to bolster its balance sheet. MGM Resorts will lease back MGM Grand and Mandalay Bay and continue to operate the hotel-casinos, as it does with the Bellagio. Blackstone, which has been on a real estate buying binge in Southern Nevada for years, will own 49.9 percent of the venture. MGM’s real estate investment trust, MGM Growth Properties, will own 50.1 percent of the joint venture and said the deal values the resorts at $4.6 billion. The deal is expected to close this quarter. New York financial giant The Blackstone Group, the Bellagio’s new landlord, announced Tuesday it agreed to form a joint venture to acquire the additional MGM Resorts International properties on the Strip.
