Imagine a luxury estate that pays for itself. At 15715 Zeigler Court in San Diego Country Estates, a fully permitted, detached ADU generates $3,000 per month in rental income—quietly transforming the true cost of luxury ownership. With 20% down, the full monthly ownership cost is approximately $9,337. Subtract the ADU income, and your effective payment drops to about $6,337—roughly the same as financing a $950,000 home. That income stream effectively delivers nearly $475,000 in additional financing power, letting you enjoy a $1,495,000 estate at a far more accessible real-world cost. Welcome to 15715 Zeigler Court, Ramona, CA 92065—a fully reimagined, single-level luxury residence perched high on a hill at the end of a quiet cul-de-sac in the coveted San Diego Country Estates. Renovated from the ground up in 2023 under the direction of award-winning La Jolla designer April Worell, this home masterfully blends architectural elegance with refined, contemporary interiors, and is delivered completely turn-key and move-in ready. The detached ±1,000-square-foot ADU, completed and fully permitted in 2023, sits discreetly on the south side of the property with its own private driveway. This stylish two-bedroom, one-bath residence mirrors the main home’s quality and enjoys the same stunning mountain views. Currently rented for $3,000 per month and valued at over $500,000, it is a turn-key income asset that enhances both lifestyle and bottom line. The approximately 2,544-square-foot main residence offers four bedrooms and 2.5 baths, finished with imported wood-grain porcelain tile flooring, quartzite countertops, and curated designer backsplashes throughout. The gourmet kitchen serves as the heart of the home, featuring custom solid wood cabinetry, an oversized island, Bosch and ZLINE appliances, alabaster pendant lighting, and powerful commercial-grade ventilation, while a stylish wine bar with floating redwood shelves adds character. The spa-inspired primary suite is a retreat unto itself, complete with a Bain Ultra stone soaking tub, a cultured limestone walk-in shower, and a Toto Washlet. Open-concept living spaces are crowned by beamed cathedral ceilings and filled with abundant natural light. Thoughtful upgrades extend throughout, including new vinyl windows, Emtek hardware, updated HVAC, a whole-house exhaust fan, a new 50-gallon gas water heater, fresh interior and exterior paint, and a durable concrete tile roof. Energy independence is a defining feature: an owned 14.4 kW solar system pairs with two Tesla Powerwall batteries and a SPAN smart panel for true self-sufficiency, while over 750 gallons of propane storage lend this estate a rare sense of security and peace of mind. Outdoors, the backyard is an entertainer’s dream, anchored by a new IGG PebbleTec pool and waterfall spa, non-slip porcelain wood-grain decking, and a new Pentair heater. Professional landscaping by Moon Nurseries includes mature lemon and pink lemonade trees alongside a beautiful cactus garden with an impressive array of species. Sweeping, unobstructed mountain views of Eagle Peak and Mount Cuyamaca—plus the privacy of backing to expansive open space and thousands of acres of public land—make this property a hidden paradise, with direct access to horse trails and miles of hiking and mountain biking trails right outside the gate. A fully insulated three-car garage and energy-efficient design complete the picture. This rare offering combines high-end living, thoughtful design, energy independence, privacy, and meaningful rental income in one of Ramona’s most desirable communities—a true lifestyle estate that lives beautifully and pays you back. With the owner relocating overseas, a 2023 Toyota 4Runner TRD Off-Road in excellent condition is included with the sale, and the home’s furnishings and personal property—down to the kitchen essentials—are available by negotiation, offering a rare opportunity to step in and start living from day one.
