772-774 Walnut Street is a well-maintained, single-story legal duplex totaling approximately 1,362 square feet on a 2,500 square foot lot in San Bruno. Built in 1959, the property consists of two thoughtfully updated units: a one-bedroom front unit of approximately 561 square feet, which is currently vacant, and a larger rear unit of approximately 801 square feet featuring one bedroom plus a fully insulated and weather-sealed 240 square foot bonus room currently utilized as a second bedroom, along with a private patio and yard. Each unit offers in-unit laundry and an enclosed garage. Strategically placed skylights fill both residences with natural light, and dual-pane windows enhance energy efficiency and comfort. Critical for investors, the tenants are responsible for all utilities, minimizing owner operating expenses. The vacant front unit gives a buyer immediate flexibility to move in or lease it at market rent. With its turnkey condition, strong unit mix, and low-maintenance single-story layout, 772-774 Walnut is ideally suited for the first-time investor, an owner-occupant seeking rental income to offset their mortgage, or a seasoned owner looking to add a stable, income-producing Peninsula asset to their portfolio.

ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
