Situated on the coveted 100 block of Coral Avenue on Balboa Island, just seven homes from the sand, 120 Coral Avenue presents a rare opportunity to own a versatile coastal property in one of the most desirable pockets of Newport Beach. The property features a 1,582± square-foot detached Spanish-style front residence, built in 1990, along with a 600± square-foot rear residence above the two-car garage, offering exceptional flexibility for rental income, guest accommodations, or extended family living. The charming front unit includes two spacious bedrooms upstairs, each with its own full bath, as well as a full bath downstairs located off of a den. The two-bedroom rear unit, paneled from floor-to-ceiling in rich pine wood, was originally constructed in the 1950s and has been thoughtfully updated over the years to meet modern living needs. Both residences underwent kitchen and bathroom updates in 2011, providing functional layouts with enduring coastal appeal. The separation between the two units allows for privacy while maintaining the charm and walkability that define Balboa Island. Carport for golf cart parking on the side of the house. Perfectly located only four streets from Marine Avenue, on one of the wider streets on the island, this property is ideal for an owner-user, investor, or anyone seeking a prime coastal location with long-term upside.
