LAS VEGAS >> Deutsche Bank AG cut itself free of The Cosmopolitan of Las Vegas resort and casino after selling the swanky, high-rise complex on the Strip to Blackstone Real Estate Partners VII for $1.73 billion.

The German investment bank said in a statement Thursday that the cash deal remains subject to regulatory approvals. The bank had intended to sell the property from before it even opened in 2010, and had placed The Cosmopolitan in a separate bank division devoted to winding down or selling unwanted investments.

Blackstone, which owns $81 billion in real estate assets globally and describes itself as the largest opportunistic real estate investment manager in the world, is in the business of buying underperforming property and re-selling it after making improvements. It owns nearly 1,000 homes in Nevada and the upscale Hughes Center office complex in Las Vegas, as well as a small portion of casino company Caesars Entertainment.

"Blackstone recognizes the value and potential in the Cosmopolitan and Las Vegas and looks forward to working to build on the success to date," Tyler Henritze, the company’s senior managing director, said in a statement.

The last major Las Vegas resort approved before the Great Recession, the $3.9 billion Cosmopolitan was built by Deutsche Bank AG after its original developer defaulted on a loan. Initially conceived as a condo complex, it retains large rooms and kitchenettes even though the project morphed into a hotel after the housing market crashed.

The Cosmopolitan has branded itself as a "decidedly different" kind of casino, eschewing the kitschy themes common among its competitors and catering to a more urbane kind of gambler and club-goer with the tagline "just the right amount of wrong."

The casino is home to Marquee, one of the top-grossing nightclubs in the United States, and features a three-story bar enveloped by a giant chandelier and restaurants run by celebrity chefs.

But its emphasis on entertainment and food over gaming, and a smaller database of regular gamblers than its casino chain competitors, hit the resort’s bottom line.

"Optimally you want to use the food and beverage as a driver for gambling," said David G. Schwartz, director of the Center for Gaming Research at the University of Nevada, Las Vegas. "They’ve definitely struggled to establish an identity as a gaming destination on the Strip."

Officials at the resort said they were "genuinely excited" to hear about the sale.

"This marks the beginning of the next chapter for The Cosmopolitan of Las Vegas and the thousands of dedicated CoStars who are committed to providing a compelling guest experience," CEO John Unwin said. "It is a testament to our unique approach to the Las Vegas market."
