Fantastic opportunity to own this prime location office building that has been the home to Gehrke Realty since 1961. This large apx 3333 sqft office building has 7 separate offices, large conference area room, mail room, kitchen area, 2 half baths, office storage/equipment room, atrium area with fountain, and 7 parking spots with ally access. Located just a few blocks from downtown Santa Rosa, near the corner of Mendocino Avenue and College Avenue, and just a couple of blocks from HWY 101. Appears to be in good shape and well taken care of through the years, but might need some cosmetic upgrades on the interior. Plan for the future!
