The Summit Office Campus in Aliso Viejo has traded hands, marking the largest office transaction in Orange County in the last six months and potentially one of the largest of the year. The five-building 479,451-sqaure-foot office campus traded hands between an unnamed global investment advisor and Rockpoint Group for an undisclosed price, but industry sources tell GlobeSt.com that it was upwards of $150 million. In addition to its size, this was a rare value-add office opportunity in the Orange County market.
