20705 Onaknoll A Rare Lake View Ranch Where Lifestyle, Land & Opportunity Converge. Welcome to a truly one of a kind equestrian retreat, a meticulously remodeled single story ranch pool home set on nearly 3 acres of fully fenced, usable land overlooking Lake Mathews. Offering panoramic lake and hill views, privacy, and endless lifestyle possibilities, this 4 bedroom home was extensively remodeled with no expense spared. Arrive through an automatic gated entry and step into a home filled with country chic charm and modern farmhouse finishes. Expansive windows frame lake, hillside, garden, and pool views from nearly every room. Wood plank tile flooring flows throughout, while the formal living and dining spaces open seamlessly to the chef’s kitchen featuring quartz countertops, KitchenAid stainless steel appliances, and a farmhouse sink perfectly positioned to take in the scenery an ideal setting for entertaining. The family room with brick fireplace sits just off the kitchen and opens to a fully enclosed addition, offering flexible space for a variety of needs. Bedrooms are generous in size, and the primary retreat opens directly to the backyard perfect for morning coffee, quiet evenings, and listening to nature. Both bathrooms have been beautifully updated with high end finishes. Outdoors, unwind in the resort style pool and spa or watch the sunset from your tree swing as the property unfolds into a versatile agricultural and equestrian setting. The land accommodates horses, includes existing stalls, and features a massive covered open air agricultural structure ideal for riding, training, storage, gatherings, or creative repurposing. A service area includes two metal shipping containers which have been used as tack and feed rooms. Additional improvements include upgraded 200-amp electrical service, two RV hookups with septic connection, RV dump area, newer septic leach lines, automatic water throughout, newer Maytag HVAC system, dual-pane energy-efficient windows, new interior and exterior doors, Pottery Barn vanities and fixtures, marble showers, new garage doors, seamless gutters, and a gravel driveway. The grounds support a true garden-to-table lifestyle with extensive mature fruit trees and garden areas. Located within the highly desirable Corona/Norco school district, this exceptional property offers space, serenity, and the freedom to create a lifestyle as expansive as the land itself. **professional photos and video to follow**
