About this home

Located on a small, quiet residential street in Seal Beach, 1521 Marine Ave presents a well-positioned 4-unit multifamily opportunity just three blocks from the beach and less than half a mile from the retail and dining along Main Street. The property consists of one 1-bedroom / 1-bath unit and three studio units, totaling approximately 2,400 square feet of rentable space on a 2,178 square foot lot. The asset offers strong current income with clear rental upside as units trend toward market levels. Additional improvements include a detached 2-car garage with on-site laundry, along with a detached storage structure featuring a fireplace, providing added utility and flexibility. With its premier coastal location, quiet neighborhood setting, and proximity to local amenities, the property benefits from consistent tenant demand. This offering presents an attractive opportunity for investors seeking stable income and long-term appreciation in a highly desirable, supply-constrained beachside submarket.
