Recently, Uber's stock started to surge back above the $45 IPO price the ride sharing app debuted at, back in May. That's good news for Garrett Camp, one of the co-founders of Uber. The stock had fallen off by 17% after its IPO. Camp and his longtime partner Eliza Nguyen celebrated that benchmark by plunking down the most amount of money they've spent to date on their vast real estate portfolio. It was also the most money ever spent for a home in Beverly Hills. The couple spent $72.5 million for an estate in the 90210's trendy lower Trousdale Estates neighborhood.
