A tech exec just bought the penthouse in San Francisco's sinking skyscraper for $13 million

The penthouse apartment in San Francisco's leaning, sinking skyscraper just sold for a whopping $13 million to a longtime fixture of Silicon Valley, Wall Street Journal reports.

Buyer Craig Ramsey, who worked at Oracle for 16 years, is moving on up from a unit he owns on a lower floor to the two-bedroom home on Millennium Tower's 58th floor.

Millennium Tower, a $350 million skyscraper completed in 2008, has sunk 16 inches and tilted two inches since it opened. Its developers, residents, and city officials have been fighting for months over who is at fault for the 58-story tower's problems.
