One-of-a-kind opportunities like this rarely become available in the heart of Round Rock!

Whether you are looking for a primary residence, an Airbnb opportunity, or a strong long-term investment property, the possibilities here are endless.
Owned by only one owner since 1996, this home has been exceptionally cared for inside and out and remains in pristine condition. While cosmetic updates could make it your own, the home is completely move-in ready and provides an incredible opportunity to personalize at your own pace.
