About This Home

As of June 2025

Welcome to your own private retreat in the highly sought-after Mockingbird Canyon community. Set on over an acre of beautifully usable land, and with a massive ADU with it's own private entrance, this exceptional equestrian estate blends elegant living with resort-inspired luxury.

The main residence has been tastefully upgraded throughout, offering a light-filled interior with soaring ceilings, fresh designer paint, and a layout ideal for both entertaining and everyday living. Downstairs, you’ll find a dedicated office, a guest bedroom with a spa-inspired en-suite bath, and an expansive bonus room—perfect for a home theater, gym, or game room. The chef’s kitchen features a spacious walk-in pantry, oversized laundry room, and abundant cabinetry, creating a perfect blend of function and style.

Upstairs, the luxurious primary suite is a true sanctuary, complete with its own cozy fireplace and a 5-star resort-style bathroom finished with premium upgrades. Additional bedrooms are generously sized and complemented by a large loft and beautifully remodeled bathrooms.

Step outside to your own private paradise, where a stunning infinity-edge pool with dual cascading waterfalls sets the tone for outdoor relaxation. The grounds are dotted with a variety of fruit trees and offer ample space for equestrian facilities, creating endless possibilities for the outdoor enthusiast.

Adding even more value to this incredible property is a nearly completed detached ADU—approximately 1,000 square feet—featuring its own gated entrance and private access. It’s just awaiting final touches including stucco, electrical connection, and kitchenette installation. Whether you envision a guest house, rental income opportunity, or private studio, this ADU adds exceptional versatility.

This is your rare opportunity to own a gated equestrian estate with resort-style amenities in one of Riverside’s most coveted neighborhoods. A true lifestyle property—luxury, privacy, and versatility all in one
