Despite being built in 1912, the property has undergone extensive and recent renovations, particularly in the top two vacant flats. The kitchens feature modern dark blue shaker cabinets, white countertops, stainless steel appliances, and contemporary light fixtures. Bathrooms are updated with modern vanities, subway tile, and new fixtures. Engineered hardwood floors are present throughout the renovated units, and the electrical systems have been updated (no knob-and-tube). These renovations are clearly recent and meet current quality standards, making the renovated portions virtually new and aligning with the 'Excellent' criteria for properties extensively renovated within the last 5 years.
Pros & Cons

Pros

Premier Nob Hill Location: Perched atop iconic Nob Hill, one block from the Fairmont and across from the Cable Car Museum, this property boasts a highly desirable address surrounded by cafes, landmarks, and excellent transit access.
Strong Income & Owner-User Potential: As a triplex with three spacious flats, a bonus studio, and one tenant-occupied unit providing stable income, it offers significant flexibility for investors seeking rental revenue or owner-users looking for partial occupancy.
Extensive Modern Renovations: The top two vacant flats have been recently renovated with updated kitchens, stainless appliances, engineered hardwood floors, in-unit laundry hookups, fresh paint, and updated electrical systems (no knob-and-tube), minimizing immediate capital expenditures.
Valuable Off-Street Parking: The property includes garage parking for three small cars, a significant and highly sought-after amenity in a dense urban environment like San Francisco's Nob Hill.
Expansion Potential & Bonus Studio: The description explicitly mentions 'expansion potential' and includes a bonus studio with a full bath, offering opportunities for future value addition or flexible use.

Cons

Age of Building: Built in 1912, despite recent renovations, an older building may still present unforeseen maintenance challenges or require specialized upkeep for its historic components over time.
Parking Size Limitation: While parking is a major asset, the specification of '3 small cars' for the garage could be a limitation for owners with larger vehicles or those seeking more versatile parking options.
Tenant-Occupied Unit Restrictions: The lower flat is tenant-occupied with a long-term lease, which, while providing stable income, may limit immediate owner-occupancy or extensive renovation plans for that specific unit due to tenant rights and regulations.
