We are pleased to present 339 N McDonnell Ave, a fully renovated duplex ideally located in the heart of East Los Angeles, just minutes from Downtown, major employment centers, and convenient access to the 5, 10, and 710 freeways. Situated in a strong, supply-constrained rental market, the property benefits from close proximity to local retail, dining, schools, and public transportation, making it highly attractive to tenants and owner-users alike. The property has undergone extensive capital improvements, including all new copper plumbing throughout both units, new windows, fresh stucco with exterior paint, refreshed landscaping, annual roof upkeep, and full pest tenting prior to renovation completion. The front unit is a spacious 3-bedroom, 2-bath residence delivered vacant and ready to achieve an estimated market rent of $3,500, featuring a complete interior renovation with new copper plumbing and gas lines, new subfloor, newer water heater, recessed lighting, updated electrical panel, custom white and green cabinetry, quartz countertops and backsplash, stainless steel appliances, mini-split HVAC, in-unit washer and dryer hookups, and modern black-accent finishes throughout. The rear unit is a well-appointed 2-bedroom, 1.5-bath currently rented at $2,255, offering similar high-quality upgrades including new copper plumbing, updated systems, quartz kitchen finishes, stainless steel appliances, mini-split HVAC, in-unit laundry hookups, and cohesive contemporary design. This turnkey duplex presents an exceptional opportunity for investors or owner-users seeking strong income potential, modern construction quality, and minimal ongoing maintenance in a prime East Los Angeles location.
