PROSSTRENGTHS & OPPORTUNITIES

The property offers breathtaking panoramic views of the hills, mountains, and valley, visible from the main living areas and the expansive lower-level deck, significantly enhancing the home's appeal.
- Prime Location and Schools
Ideally situated within walking distance of top-rated schools like Chabot Elementary and minutes from Lake Chabot Regional Park, offering a perfect balance of suburban convenience and outdoor recreation.
CONSRISKS & DEFICIENCIES
- MLS Listing Discrepancy
Living area discrepancy between mls listing and other public or private record. mls listing living area = 2380, other record living area = 1828. 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
The 5,200 sq ft lot is relatively compact for a five-bedroom residence, which may limit outdoor activities or privacy compared to other properties in the Castro Valley area.
- Vintage Infrastructure
Despite the remodeled kitchen and dual-paned windows, the 1958 build date suggests that some original structural or mechanical systems may require further inspection and potential modernization.
