Muller and Cigna Put 104,000 SQFT 550 Winchester Office Building Beside Santana Row on the Market in San Jose

The Muller Company and Cigna Investment Management are marketing 550 Winchester, the six-story office building they bought beside Santana Row in 2019 and spent millions repositioning, putting a second Class A building on the same San Jose block up for sale only weeks after Grosvenor Americas began seeking offers for its neighbor at 560 South Winchester.
