11602 Lampson Welcome to 11602 Lampson Avenue, a rare and truly one-of-a-kind income-producing compound located in the heart of Orange County, just minutes from Disneyland and world-class beaches. Available for the first time since 1995, this massive estate sits on a secluded, sprawling lot of over a half-acre (25, 400 sq. ft.), offering unparalleled privacy, custom upgrades, and a staggering $10, 180 in total monthly rental income.Vehicular storage and utility on this property are completely unrivaled. A private gated driveway opens to a robust 700 sq. ft. metal frame carport, 5 covered patio parking spaces, and 4 dedicated open parking spaces-plus full RV hookups. Mechanics, car collectors, or business owners will also leverage the substantial 789 sq. ft. detached 4-car garage/workshop.The main residence spans an expansive 7, 147 sq. ft. of living space, wrapping gracefully around a serene, central courtyard oasis that has been freshly filled and leveled for low-maintenance outdoor entertaining. Designed with ultimate versatility, the main home features 7 bedrooms, multiple split-living quarters with private entrances. It is currently leasing for $6, 980 per month, proving its immense value as a high-end rental or multi-family footprint.Adding incredible cash-flow value is the brand-new, fully permitted detached ADU, currently leased at $3, 200 per month. Built with its own separate city address and a dedicated 1-inch water meter, this modern secondary home offers a highly desirable 3-bedroom, 2-bathroom layout with a spacious living/dining area.Best of all, both the main residence and the ADU feature fully paid-off solar systems, drastically lowering utility costs and maximizing your net profits.
