Property Description

This unique property features two separate remodeled homes (one with high end finishes) situated on one expansive lot, offering excellent flexibility for multi-generational living, rental income, or future development potential. Both homes enjoy a prime location within walking distance to Castro Valley Boulevard’s shopping, dining, and everyday conveniences. Commuters will appreciate the easy access to major freeways, making travel throughout the Bay Area simple and efficient. The large lot provides abundant outdoor space for gardening, entertaining, or expansion, while also presenting exciting possibilities for investors or builders seeking to maximize value. Whether you’re looking for a live-in one, rent-the-other setup, extended family housing, or a property with long-term upside, this Castro Valley gem checks all the boxes. Don’t miss your chance to own two homes on one lot in a convenient and desirable location with tremendous further development potential! Check with Alameda County to confirm that the lot supports up to 8 condos or townhomes or if you could do a 5 way lot split and build 3 additional detached separate homes. New central heat and A/C in main house. Both houses have new water heaters.
