It is an office complex in Manhattan Beach, California, sleek and attractive but otherwise unremarkable — until now.

The property, built in 1985 and consisting of two six-story office towers, is not quite as pricey as Frank Mulder’s 405-foot “Gigayacht,” which was listed on eBay for $168 million. EBay has not confirmed that it went for that price. It does top Mark Cuban’s online purchase of a Gulfstream jet for $40 million, which is confirmed by Guinness World Records.

Until now, real estate auctions, both on and offline, have primarily been used to dispose of distressed assets. But as the rest of life moves online, so, too, do real estate sales, in ever more expensive offerings.
