PRICE IMPROVEMENT! AMAZING OPPORTUNITY! YOUR PRIVATE LAKE AWAITS — LA MARQUESA Imagine waking to still water, towering oaks, lakefront tullies and birdsong, where the city feels a world away—yet downtown San Diego is approximately 40 miles from your door. Welcome to La Marquesa, an extraordinary 7,117 sq. ft. lakefront estate set on 7+ peaceful acres and one of only two residences privileged with access to this private, stocked lake. Expansive decks overlooking the water and mountains invite quiet mornings, spectacular sunsets and evenings beneath the stars. Inside, four spacious bedroom suites each offer an ensuite bath, complemented by two optional bedrooms, 6 full baths and a powder room. The dramatic great room, grand fireplace and rich English-style pub create an unforgettable setting for entertaining. The generous kitchen features quartz counters, center island, 8-burner Viking range/oven, stainless appliances, abundant cabinetry and Travertine flooring. A sweeping circular staircase, crystal chandelier and distinctive architectural details add timeless character. This is more than a home—it is space to breathe, room to gather and the privacy to truly escape. Properties like La Marquesa rarely come along. Come experience it in person—because photographs can capture the home, but they can't capture the feeling of being here. Views from every room! This is
