This week in celeb real estate: Movie exec Roger Birnbaum accepts price chop in Beverly Hills, Michelle Obama rents in the hills…and more

A movie mogul sold his home at a sharp discount. A billionaire venture capitalist dropped a — relative — pittance on an abode and a former first lady rented a “Shark House.” They all contributed to the week real estate moves around Los Angeles.

Roger Birnbaum, founder of Spyglass Entertainment, has sold his home in Beverly Hills for $21.4 million, roughly 37 percent less than his original asking price. The Hollywood producer first put the 8,000-square-foot home on the market last year, after paying $20 million for it in 2014. Designed by architect Harold Levitt, the home includes four bedrooms, seven bathrooms, a 500-square-foot music room and a swimming pool. Birnbaum’s long list of credits include hits like “No Strings Attached,” “The Rush Hour” franchise and “Get Him To The Greek.”

Former L.A. Clippers Austin Rivers sold his home in the Pacific Palisades for $6.9 million, just two weeks after agreeing to a two-year deal with the Houston Rockets. He listed it in December after the Clippers traded him to the Washington Wizards.The three-story home features six bedrooms and seven bathrooms, the Los Angeles Times reported. There’s also a barbecue, wine wall and home theater. Rivers, whose father, Doc, coaches the Clippers, paid $6.1 million for the pad in 2016.

One of Silicon Valley’s most controversial billionaires is expanding his spread in Southern California. Peter Thiel spent $5 million to acquire a 4,210-square-foot home in the Hollywood Hills, Variety reported. That’s about $2.5 million less than what the home sold for four years ago, when the late heiress of Aurrerra grocery stores bought the home. The estate of Marisa Anago put the home up for sale shortly after her death, for nearly $6 million. It boasts three bedrooms and three bathrooms. Thiel already owns a much larger spread in the area, which he paid $11.5 million for in 2012.

Michelle Obama isn’t scared of sharks. The former first lady rented the 12,000-square-foot spec home, dubbed “Shark House,” which is on the market for $23 million. The Hollywood Hills home has seven bedrooms, two pools, and of course, an open-air aquarium with sharks.

A former USC coach who became embroiled in the college admissions scandal has parted ways with his home in Rancho Palos Verdes. Jovan Vavic sold his 3,200-square-foot pad for $2.5 million, after listing it in April. It has four bedrooms and four bathrooms, as well as ocean views. The water polo coach has been accused of accepting $250,000 in bribes.
