Young Lewin Advisors, as the exclusive listing agent, is pleased to present 10621 San Carlos Ave, a six-unit multifamily investment opportunity located in the City of South Gate. The property consists of six (6) spacious two-bedroom / one-bathroom units averaging approximately 766 square feet each, situated within a 4,600-square-foot building on a 6,282-square-foot lot. Held and maintained by the same family for decades, the asset represents a rare pride-of-ownership offering. The property has benefited from meaningful recent capital investment. Improvements include a new main electrical panel with six new individual unit subpanels (2026), a replaced water heater (2026), a reflective silicone roof (2021), and fresh exterior paint with fascia work throughout (2020). Unit D has been fully renovated with new flooring, a new kitchen, and a new bathroom. The units are separately metered for gas and electric, and the property features fully secured and gated parking at the rear with no tuck-under component. Priced at $229,167 per unit and $298 per square foot, 10621 San Carlos Ave is offered at a 5.48% current cap rate and an 11.07 current GRM — pricing supported entirely by in-place income. Current rents sit approximately 25% below market, offering a new investor a clear and quantifiable path to income growth through allowable annual increases and natural turnover. South Gate has never adopted a local rent stabilization ordinance, leaving the property governed solely by California's statewide Tenant Protection Act (AB 1482), which currently permits annual increases of up to 8.7%. Combined with recent capital improvements, a solid unit mix, and durable tenant demand throughout South East LA, 10621 San Carlos Ave offers an attractive combination of stabilized in-place cash flow and defined future upside.
