Exceptional value-add duplex opportunity on a large, flat lot in a highly desirable Monterey Park location within the sought-after Mark Keppel High School district (buyer to verify)! This versatile property is ideal for investors, developers, or first-time buyers looking to live in one unit while generating income from the other. The rear unit (#335) has been fully renovated and previously operated as a successful short-term rental, performing very well and offering strong income potential. Perfect for immediate rental use, extended family, or in-law living. The front home (#339) has been fully gutted to the studs and comes with approved plans for a spacious 3-bedroom, 3-bathroom layout-providing a rare opportunity for the next owner to design and complete their dream home to their own taste while saving significant time and demolition costs. Situated on an expansive lot, the property offers ample parking for 6+ vehicles and includes a detached 2-car garage with excellent potential for Junior ADU conversion and possible expansion (buyer to verify), creating even more income opportunities. Whether you're looking to create a multi-generational living setup, offset your mortgage with rental income, or invest in a property with strong upside and flexibility, this is a unique opportunity you won't want to miss.
