Amazon.com, already one of Seattle’s largest employers, now is also one of its biggest property-owners.
The online retailer closed Friday on the purchase of its 11-building South Lake Union headquarters campus, previously leased from Paul Allen’s Vulcan Real Estate.
Amazon paid Vulcan $1.154 billion, according to public records. That’s slightly less than the $1.16 billion price tag the companies put on the deal when they announced it in early October.
Research firm Real Capital Analytics said at that time that the deal was in line to be the country’s largest single-asset commercial real-estate transaction of the year. It’s also King County’s biggest sale since 2007, when the 28-building Equity Office Properties portfolio changed hands for $2.76 billion.
