Condition Analysis

Poor
TeardownExcellent
Property is extensive renovation needed.
Built in 1949 and owned by the same family for decades, the property shows no signs of recent renovation. The kitchen features original-style cabinetry and appliances that are over 50 years old, and the interior finishes are severely dated, indicating a need for a full rehab of the kitchen, bath, and likely the electrical and HVAC systems.
PROSSTRENGTHS & OPPORTUNITIES
- Significant Renovation Potential
As a long-held family home in original condition, this property serves as a blank canvas for investors or buyers looking to build equity through a complete custom remodel.
- Expansive Lot Size
The 4,680 sqft lot provides a generous backyard and ample space for potential home expansion or the addition of an Accessory Dwelling Unit (ADU) to maximize value.
- Prime Commuter Location
Ideally situated near major transportation routes, shopping, and everyday amenities, including close proximity to South San Francisco High School.
CONSRISKS & DEFICIENCIES
- Cramped Living Proportions
With only 750 square feet of living space distributed across three bedrooms, the interior layout is exceptionally tight and may not meet modern functional standards.
- Limited Bathroom Facilities
The home features only one bathroom to serve three bedrooms, which is a significant drawback for family living and may impact the property's competitive market value.
