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.
