His tempo has picked up because of them. Mattson has quietly been shopping residential and commercial homes in addition to vacant lots, both inside the city limits and around the Valley. As of press time, consistent with CoreLogic’s actual property reports, he now owns all or a part of 26 Valley residences totaling nearly $80 million.
Two property dealers acquainted with the neighborhood market agreed that Mattson is now one of the most important (non-winery) landowners in the Valley.
Most wonderful were Mattson’s purchases, through his real estate corporation, LeFever Mattson, of Cornerstone Sonoma marketplace, Ramekins culinary faculty, and the General’s Daughter event space from Kenwood Investments.
But Mattson additionally now owns Leland Fishing Ranch assets on Arnold Drive, the old Cocoa Plant constructing on Broadway, Cottage Inn & Spa downtown, a portion of the Mercado assets at the Plaza, the Sojourn tasting room constructing on East Napa, and the list goes on.
