Rare fixer-upper opportunity in the highly desirable Cowan Heights neighborhood of unincorporated Orange County. Situated on a flat and highly usable 1.19-acre lot, this single-story residence offers exceptional potential for the right buyer to renovate, expand, or reimagine into a custom estate.
Located at 9931 Highcliff Dr, the home features approximately 4,421 sq. ft. of living space with 6 bedrooms, 3.5 bathrooms, and a private pool. The original single-level floor plan provides an excellent foundation for a major transformation, while the usable lot offers a significant advantage for future improvements, outdoor living areas, expansion, or possible additional structures, subject to county approval.
Unlike many hillside properties in the area, this lot offers a more practical and buildable setting, making it easier to improve and customize. Whether you are an end-user with vision, an investor, or a buyer looking to create a private Orange County estate, this property presents a rare value-add opportunity in a premier neighborhood.
Enjoy privacy, space, and the peaceful Cowan Heights setting while remaining close to shopping, dining, schools, trails, and major Orange County conveniences. A unique chance to secure a large single-story home on over an acre and unlock its full potential.
