1780 Santa Ana Avenue is a rare Eastside Costa Mesa triplex hitting the market for the first time in over 50 years. The property features three large 2BR/1.5BA townhome-style units, each approximately 1,250 SF, for a total building size of 3,750 SF situated on an 8,321 SF lot. A new roof was completed in 2025, significantly reducing near-term capital expenditures. Located just off 17th Street—one of the most desirable pockets in Costa Mesa—this asset sits among strong demographics, walkable amenities, and consistent tenant demand. All units are fully occupied with long-term tenants and are separately metered, providing stable income with clear operational upside over time. This is an extremely hard-to-replicate location and unit mix in a supply-constrained submarket known for long-term appreciation and minimal vacancy. An excellent fit for local investors, long-term holders, and 1031 exchange buyers.
