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.

No weekly rateNo published rate within 7 days of this date.ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
Mortgage benchmark: Freddie Mac Primary Mortgage Market Survey®. © Freddie Mac. Weekly national 30-year fixed rates, not APRs or a loan quote. Actual terms vary. Methodology changed in November 2022. The chart does not establish that interest-rate changes caused a home’s price changes.
Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
