Welcome to 3733 Castle Rock Drive in the heart of the popular Preserve at Stone Oak community! From the moment you step on the property, you can appreciate upgrades like the brand-new insulated garage door and fresh landscaping. The entire property (interior and exterior) was just fully professionally painted and lives like a new home. The backyard is perfect for entertaining, with a covered patio, a gas grill, and a gas stub to power additional grilling equipment. (There's also a gas connection for dryer in laundry room.) A 20x10 shed with a porch and electric sits in the back corner, complete with lush, established grass. The new fence has been installed with tastefully stained. This beautifully maintained home features a 5.6kW solar panel system paired with a 13.3kWh backup battery, capable of powering the house for up to two weeks-an excellent safeguard during winter storms. Recent upgrades include new windows (minus one) (2020), a 20 SEER HVAC system inside and out (2021), a water heater (2022), and tasteful cosmetic updates throughout. Upgrades include wood-tile flooring, granite countertops, 2024 dishwasher, 2024 stove plantation shutters, retractable custom roman shades, new door hardware and hinges, freshly painted cabinets, new light fixtures, and a fully renovated owner's suite bathroom.  The outdoor hot tub (less than a year old) conveys! The neighborhood HOA amenities includes two pools (heated Jr. Olympic-sized pool + kiddie pool), clubhouse, and multiple parks and playgrounds. The nearby greenbelt offers over 30 acres of  trails and outdoor spaces as well! This location is in close proximity to Sam Bass, 1431, I35, 1431, and 183-A; it is within minutes from Williamson County Park, Round Rock Premium Outlets, hospitals, entertainment, shopping, and dining. Enjoy a low tax rate and HOA monthly fee! This property is zoned for high-ranked schools in RRISD. A must see! Request electric utility bills to check out the saving benefits from the solar panels!
