Just months after T-Mobile committed to stay at its Bellevue, Wash. headquarters, the owner of the campus has decided to cash out. Canadian real estate company Ivanhoe Cambridge sold the Newport Corporate Center to Los Angeles-based Preylock Real Estate Holdings for $467.5 million, according to records filed with King County. In November, T-Mobile announced it planned to stay at the campus just off Interstates 90 and 405 in Bellevue through at least 2030. The deal was first spotted by Puget Sound Business Journal.
