1820 THACKER Avenue Zoned CRO -- live in it, work in it, or both. Built in 1927 and holding onto everything that makes homes of that era worth owning: original hardwood floors, a working fireplace, and proportions you don't get in new construction. The kitchen has been opened to the adjacent living space with a bar added, so the floor plan lives modern on pre-war bones. Four true bedrooms and two full baths across 1, 618 heated square feet. Newer roof (2020) and HVAC (2021). Outside, a pavered driveway and a gated, fully fenced backyard. The CRO zoning is the rare part. Run a practice out of the front, live in the back. Or keep it fully residential and simply own the optionality. Properties with this designation don't come up often in the greater San Marco area.
