A rare opportunity to own one of the most expansive residences in the Carson Park area, 4125 Los Coyotes Diagonal offers approximately 3,164 sq ft of modernized living with 6 bedrooms, 3.5 baths, exceptional flexibility, and a scale seldom found nearby. More than a cosmetic renovation, the home underwent substantial City-permitted modernization with final sign-off, including structural and foundation upgrades, an upgraded electrical panel, new flooring, dual-pane windows throughout, new interior and exterior doors, redesigned kitchen and baths, fresh paint, and individual mini-split climate control in the bedrooms and main living areas. Permit records are available for buyer review. Designed for today's lifestyle, the generous two-story floor plan is well suited for large, extended, or multigenerational households. Two separate entrances, multiple gathering spaces, and two laundry areas create natural privacy and flexibility for family, in-laws, guests, work-from-home needs, hobbies, or future reconfiguration. The front portion, all on the first floor, includes 3 bedrooms, living and dining areas, and its own laundry area. A separate entrance opens to a spacious first-floor family room with its own laundry area and provides access to the upstairs wing with 3 additional bedrooms and 2 baths. The property is currently one single-family residence; buyers may explore possible separate-living or income-use configurations. Energy-conscious buyers will appreciate the dual-pane windows and room-by-room climate control. EV households will love the rare 3-car garage with three 240V/50A connections for EV charging, plus 2 side-yard parking spaces and street parking. The oversized family room, complete with a fireplace, adds warmth, character, and an inviting gathering space for family and friends.
