Condition Rating
Good

This property features two homes with varying levels of renovation. The main house (as seen in images 2-5) appears to have undergone a recent, high-end renovation, boasting modern recessed lighting, dark hardwood floors, a contemporary electric fireplace, and a kitchen with high-end stainless steel appliances, stylish cabinetry, and stone countertops. The main house also benefits from new central heat and A/C. The second home (images 6-8), while also remodeled, features more standard updates, including a functional but less luxurious kitchen with stainless steel appliances and white shaker cabinets, and a bathroom with a basic pedestal sink and a dated fiberglass/acrylic shower enclosure. Both homes have new water heaters. The overall condition is 'Good' because the primary residence is in excellent, move-in ready condition with modern features, and the second unit is also updated and functional, though its bathroom and lack of central HVAC prevent the entire property from reaching an 'Excellent' rating. The property's original build year of 1925 is largely mitigated by these extensive renovations.

Cons

Unconfirmed Development Potential: The significant development potential for additional units or lot splits requires confirmation with Alameda County, indicating it's not yet guaranteed or approved.
Age of Property: Built in 1925, despite remodels, the age of the property may imply older underlying infrastructure or potential for unforeseen maintenance requirements.
Potential Disparity in Home Amenities: While one home has high-end finishes and the main house has new central HVAC, the description does not explicitly confirm the same level of updates or HVAC for the second home, potentially leading to an imbalance.
