Positioned in the heart of Castro Valley, 20411 Santa Maria Avenue offers a rare mixed-use investment opportunity featuring five retail storefronts complemented by a duplex situated behind the commercial frontage, creating multiple income streams within a single asset. Located just moments from Castro Valley Boulevard, the property benefits from strong visibility and consistent foot traffic driven by a dense mix of local businesses, dining, and daily-needs retail that support long-term tenant demand. The surrounding residential neighborhoods, known for their stability and desirability, further reinforce the strength of the retail component while providing a reliable tenant base for the duplex units. With convenient access to I-580, BART, and major commuter corridors connecting to Oakland, Silicon Valley, and the broader Bay Area, this location continues to attract both commercial and residential tenants alike. Combining a strategic location, diversified income potential, and proximity to key economic drivers, this asset presents an excellent opportunity for investors seeking stable returns with future upside in a supply-constrained market.
