GT Capital JV Buys Downtown Seattle Tower for $48M

The asset's sale price is down 84.1 percent compared to its 2019 transaction.

GT Capital, in partnership with The Benaroya Co., purchased 901 Fifth, a 540,589-square-foot office property in downtown Seattle.

Vanbarton Group sold the asset for $48.3 million, or approximately $89 per square foot, according to Yardi Matrix information.

The tower previously changed hands in 2019, when Vanbarton Group picked it up from Schnitzer West for $304.5 million, or about $563 per square foot. At the time, Deutsche Bank Trust Co. issued a $199.1 million acquisition loan, the same source shows. The current sale price marks an 84.1 percent decline from its previous transaction.        

Located at 901 5th Ave., the office tower is near Madison and Marion streets, with Interstate 5 just one block away. Multiple dining and transportation options are within walking distance in Seattle’s central business district.

Completed in 1973, the 41-story building underwent a complete renovation in 2007, followed by cosmetic upgrades 10 years later. Floorplates range between 8,339 to 17,428 square feet. Amenities include a 65-seat high-tech conference center, fitness center, secure bike storage, coffee shop/deli, valet parking and outdoor terrace. The tower holds LEED Platinum, WELL and Energy Star certifications.

The property serves as the U.S. headquarters of PitchBook, a Morningstar-owned data and software company. The tenant roster also features Washington State University, Avenue5 Residential and Investors Capital Group. JLL oversees leasing.

Downtown Seattle office transactions remain limited

The sale of 901 Fifth comes amid limited transaction activity in Seattle. Yardi Matrix tracks 12 office assets within 5 miles of the tower that traded between January and September 2026, amounting to 1.6 million square feet. The deals totaled $124.6 million, or $180 per square foot, on average.

The Emerald City is also among the metros facing elevated maturity risk. Roughly 70 percent of its $8.3 billion office loan volume issued before 2021 is set to mature by the end of 2028. Meanwhile, despite an overall improvement in office attendance on the West coast, Seattle’s vacancy rate remains elevated at 24.7 percent in August.
