Investment Insights

Based on property information with market context.

This 1,776-square-foot duplex includes two similarly configured residences arranged back-to-back, with separate living environments and practical privacy between the units. Both interiors have been updated with remodeled kitchens and bathrooms, new flooring, fresh paint, dual-pane windows, newer air conditioning, copper plumbing, upgraded electrical service, and a new roof layer. Drought-tolerant landscaping and mature hedges frame the front of the property.

The rear improvements include two detached single-car garages and additional parking. One residence is tenant occupied, while the other has been used by the owner’s family, creating flexibility for continued occupancy, multigenerational use, or rental income. Built in 1948, the property is located in North San Gabriel with access to shopping, dining, parks, schools, and major transportation routes. The existing configuration may also allow exploration of three-bedroom layouts or ADU potential.
