Condition Rating
Fair
Built in 1947, this duplex is described as 'well-maintained,' which is evident in the images showing a clean exterior and functional interiors. However, the kitchens and bathrooms, while clean, feature dated styles. Kitchen 1 has light wood cabinets, speckled granite, and tile flooring, likely updated 15-25 years ago. Kitchen 2 appears older with darker cabinets and black appliances. Bathrooms also show older vanities, though one shower has more recent tiling. The property is aged but functional, requiring minor aesthetic updates to meet current standards rather than major repairs or rehabilitation.
Pros & Cons
Pros
Great Schools: Middle School: Ralston Intermediate School (9/10). High School: Carlmont High School (9/10).
Income-Generating Asset: As a well-maintained duplex, the property offers immediate income potential, a highly desirable feature in the competitive San Mateo market.
Significant ADU Potential: The reinforced lower level provides a substantial 1,395 square feet of space, offering a clear opportunity to add an additional dwelling unit (ADU) for increased rental income or multi-generational living.
Prime Bay Area Location: Located on the southern border of San Mateo and Belmont, the property benefits from a highly sought-after address with access to excellent schools, amenities, and proximity to major employment hubs.
Well-Maintained Condition: The property is explicitly described as 'well-maintained,' suggesting a history of care and potentially fewer immediate repair needs for a new owner.
Recent Price Adjustment: A recent $50,000 price reduction signals increased seller motivation and may present a more attractive value proposition for prospective buyers.
Cons
Property Age: Built in 1947, the property is over 75 years old, which may imply aging infrastructure, systems (plumbing, electrical), and finishes that could require significant future capital expenditures.
ADU Requires Investment: While ADU potential is a strength, realizing it necessitates substantial financial investment, permitting, and construction, which is a significant undertaking for the buyer and not a ready-to-use feature.
Lack of Specified Modern Updates: Despite being 'well-maintained,' the description does not highlight any recent major renovations or modern amenities, suggesting the interior may be dated and require cosmetic or functional upgrades to meet current buyer expectations.
