Hilltop setting, valley views, sunset skies, steel-frame construction, reinforced storm room, guest house potential, and 5.15 acres come together at 1301 Altwein Rd in Blanco, where the setting at approximately 1,900 feet above sea level creates a true Hill Country backdrop with sweeping views, dark night skies, and unforgettable sunsets. Built in 2009, this 1,581 sq ft home offers 1 bedroom and 1 bathroom with outstanding flexibility for future growth, including plenty of room to add additional bedrooms and an easy option to convert the storage/utility room into another bedroom. The home was built with a thick steel frame rather than wood framing, adding a superior construction feature, and also includes a reinforced storm room for added function and peace of mind. A massive attic access area provides the opportunity to create substantial additional living space with tall ceilings, giving buyers even more ways to expand and personalize the home over time. The property is partially fenced and served by electric, a water pump with a 2,000-gallon tank, filtered water pumped into the house, a water softener, a 3-ton central HVAC, a 2024 water heater, and all appliances convey. Also on the property is an approximately 400 sq ft incomplete guest house with a metal roof, electrical and plumbing already installed, double-pane windows in place, partial siding, and a concrete pier-and-beam foundation, with wood materials and a mini-split also on site. In addition to completing the guest house, there is potential for 2 more similar guest homes or office spaces for investment income or possible bed-and-breakfast use, subject to buyer due diligence and verification. Beyond the improvements, this property offers the experience of Hill Country living with seasonal full moon views, stargazing, wildlife sightings, southern breezes, nearby wineries, and easy access to the Blanco River, Blanco State Park, and Pedernales Falls State Park.
