Rare opportunity to acquire a fully occupied and extensively improved fourplex in highly coveted Eastside Costa Mesa. 180 Rochester Street features four matching two-bedroom, one-bath residences, providing an efficient and highly marketable unit mix with immediate rental income from day one. Each residence offers contemporary kitchens and bathrooms, upgraded flooring, doors, recessed lighting, appliances and design-forward finishes. Extensive remodeling and capital improvements completed between 2020 and 2026 include the roof, windows, interior and exterior walls, drain systems, fencing, landscaping, driveway and hardscape, substantially reducing near-term capital needs. Additional features include separate utility metering and a dedicated common laundry room. Parking is exceptional for the area, with a carport providing covered parking for up to seven vehicles and space for nine vehicles onsite in total. The property contains approximately 3,325 square feet of building area on an approximately 7,706-square-foot lot. Located within walking distance of the 17th Street corridor and close to the dining, shopping, recreation, Newport Beach access and lifestyle destinations that define Eastside Costa Mesa. With all four units currently occupied, the property offers a strong existing rent roll, immediate income and compelling long-term upside through future rent growth, continued tenant demand and the enduring value of a scarce four-unit Eastside asset. An ideal opportunity for a 1031-exchange buyer, private investor or long-term owner seeking a turnkey residential income property in one of Costa Mesa's most desirable rental markets.
