Excellent
TeardownExcellent
Property is new construction or fully renovated.
Although originally built in 1945, the property has undergone a comprehensive recent renovation (likely within the last 5 years) including a remodeled kitchen, updated bathrooms, and a modern 2-bedroom ADU conversion. The home features high-value system upgrades such as energy-efficient mini-split HVAC, a leased solar system, and dual-pane windows. The interior shows mint-condition finishes with new flooring and fresh paint throughout, requiring no immediate maintenance.
PROSSTRENGTHS & OPPORTUNITIES
- Income Potential & Versatility
The detached garage conversion into a 2-bedroom, 1-bathroom unit provides a turnkey opportunity for rental income, guest accommodations, or multi-generational living.
- Prime Location & Schools
Ideally situated within walking distance to the highly-rated Chabot Elementary School and close to Lake Chabot Regional Park, offering significant appeal for families and outdoor enthusiasts.
- Modernized Infrastructure
The property features extensive updates including a remodeled kitchen, updated bathrooms, energy-efficient mini-split AC, and dual-pane windows, ensuring modern comfort in a classic 1945 build.
CONSRISKS & DEFICIENCIES
- MLS Listing Discrepancy
Living area discrepancy between mls listing and other public or private record. mls listing living area = 1934, other record living area = 1454. Bedroom count discrepancy between mls listing and other public or private record. mls listing bedroom count = 5, other record bedroom count = 3.
- Limited Lot Size
With five bedrooms and four bathrooms distributed across two structures on a 5,418 sqft lot, the remaining private outdoor space is relatively constrained for a property of this capacity.
- Leased Solar Commitment
The solar system is leased rather than owned, which requires the buyer to assume an ongoing financial contract and may be a deterrent for those seeking a debt-free utility setup.
