Property Description

Welcome to Casa Blanca Avocado Ranch—an extraordinary legacy estate where luxury living, commercial functionality & agricultural production converge on about 7 acres overlooking the sparkling waters of Lake Mathews. Whether you're an entrepreneur, investor, collector, or seeking an exceptional private estate, Casa Blanca Avocado Ranch presents an opportunity unlike any other in Southern California. The beautifully appointed main residence spans approximately 3,500+ sq, ft & features 3 spacious bedrooms, 3 bathrooms, a private office, family room, wet bar, & an attached 3-car garage. Designed for both everyday living & entertaining, the home opens to a resort-inspired backyard complete w/a sparkling private pool/spa & tranquil views of the surrounding orchard & rolling hills. Perfect for extended family, guests, caretakers, or additional rental income, the property also includes a private 1-bedroom, 1-bath guest area with in-unit laundry & an attached workshop. For automotive enthusiasts, business owners, and investors, the property's crown jewel is its impressive 6,000-square-foot insulated steel industrial warehouse, thoughtfully equipped with 200-amp, 3-phase power, a large bridge crane for moving heavy equipment, built-in custom air compressor systems, & three oversized 16'x14' roll-up doors. Inside you'll also find a conference room, office, file room, & 3/4 bath, creating an ideal environment for manufacturing, restoration, fabrication, storage, or numerous commercial applications. An additional 3,000-square-foot covered rear patio provides valuable space for equipment storage, RVs, trailers, or expanded operations. With generous parking accommodations for vehicles, trucks, or trailers, the property is well-suited for both personal and business use. Beyond its impressive improvements lies a thriving agricultural component featuring hundreds of mature avocado trees along with an exceptional collection of citrus and specialty fruit trees, creating the potential for agricultural income while enhancing the estate's natural beauty. This gem can accommodate 4 parties per year w/an MTE permit. Few properties can seamlessly combine residential living, industrial infrastructure, agricultural production & recreational enjoyment. Per the county, a combination of 2 additional residences (ADU and JADU) or a large residence approximately 200% the size of the original residence. Buyers are encouraged to verify all zoning & land use possibilities with the County.
