About This Home

Properties like this don’t come along often - backing to a neighborhood-maintained greenbelt with amazing views! With the updates already completed - including the kitchen, bathrooms, lighting, and hard-surface flooring throughout - this move-in-ready home lets you settle in and enjoy the setting from day one. Regularly mowed grass and trimmed trees give the greenbelt a park-like feel right behind the home, with gorgeous views from several rooms and the spacious covered patio. Private gate access from your backyard connects you to a hike-and-bike trail leading to Rattan Creek Park, just a short walk away, with playgrounds, tennis and sports courts, and a Junior Olympic-sized pool open year-round. The floorplan makes entertaining easy, with formal living and dining areas downstairs and a huge covered patio overlooking the scenic backyard. Upstairs, a second living area provides plenty of room for a media or game room. The neighborhood offers impeccably maintained amenities, along with a vibrant community hosting events throughout the year. Zoned to excellent Round Rock ISD schools, with Pond Springs Elementary just a few blocks away, the home also puts you in the heart of NW Austin’s tech corridor - just one mile from Apple’s new campus and only 10 minutes from Austin’s second downtown, The Domain. Enjoy the energy and convenience of city living with room to breathe, peaceful greenbelt views, and nature right outside your back gate! ****This property qualifies for 1% loan credit- inquire for details!*******
