The property includes a two-car garage and an in-ground spa. Situated only a few feet from downtown Castro street in old town Mountain View, this home is located in one of the most desirable areas of Silicon Valley. Currently hosts 3 distinct postal addresses (434, 432, and 430 Franklin St)! Its zoned R1 but currently able to host 3 separate tenancies, meaning the owner gets all the upside of a true triplex with NONE of the downside and with FULL AUTHORITY to tear down and rebuild at-will.
