Executive Summary

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.
The front parking is on an easement. No inspections have been performed, no Phase 1 reports. No court approval required at this time.
There is no offer date and we do have offers.  We submit the offers as they come in. Allow 7-10 days for attorney review.
We have not seen the interiors. We are scheduling that for later this week. 
Regarding the electrical panels, you will have to determine during your site walk.  We will try and obtain photos and upload them.
We will be scheduling a showing for offers that meet the seller's threshold.
