About This Home
Discover a rare opportunity to own a custom-built ranch estate nestled on 40 breathtaking acres in San Marcos. Designed for both relaxation and recreation, this exceptional property offers the perfect balance of privacy, natural beauty, and everyday convenience. The 4 bedroom, 4 bathroom residence, plus dedicated office, is thoughtfully positioned to capture the beauty of the surrounding Texas Hill Country while providing comfortable, spacious living. Outside, the property is tailored for an active lifestyle, featuring a resort-style pool with a pool chiller, turfed and paved play area, jungle gym and built-in trampoline. Additionally, the property features a generator, double septic-system, loft space above 3-car garage as well as a built in gym within the garage, and expansive outdoor spaces ideal for gathering with family and friends. With direct access to the scenic Blanco River, a barn, chicken coop, and a large outbuilding suitable for recreation, hobbies, equipment storage, or future expansion, the possibilities are endless. Currently benefiting from an agricultural exemption, the property is perfectly suited as a gentleman's ranch, private family retreat, or multi-generational compound. Ideally located along Post Road, this ranch offers easy access to Texas State University, downtown San Marcos, and a convenient commute to Austin. Enjoy the peace and freedom of country living without sacrificing proximity to shopping, dining, entertainment, and modern conveniences.
Two thousand six hundred seventy-six Post Road sits on 40 acres of cleared Texas Hill Country land with direct Blanco River access, a rare configuration for San Marcos properties that combines genuine self-sufficiency infrastructure with full modern comfort. Built in 2023, this 4,157 square foot custom residence was engineered around energy independence and resource autonomy. The property runs on a whole-home generator system paired with backup power, a double septic system handling waste treatment completely off county lines, and a private maintained road ensuring exclusive access without dependency on public infrastructure. These aren't afterthoughts - they're the foundation of how the home operates.
The main residence contains four bedrooms, four full bathrooms, and a dedicated study with data wiring that functions as a home office or additional workspace. The kitchen features granite countertops, a gas range with cooktop, built-in refrigerator, stainless steel appliances, and a wine refrigerator - the infrastructure of comfort despite the property's independence. Primary bedroom sits on the main floor with a soaking tub and walk-in closet. Open floorplan with a breakfast bar, kitchen island, and recessed lighting throughout. A three-car garage includes loft space above and a built-in gym, expanding usable square footage beyond the house itself.
Water comes from well systems rather than municipal supply, reducing long-term utility costs and eliminating service interruptions. The 40-acre lot supports agricultural operations - a functioning barn, chicken coop, and large outbuilding perfect for equipment storage, hobbies, or expansion. Moderate tree coverage provides natural wind breaks and privacy screening. Exterior amenities include covered porches, patio space, outdoor grilling, and landscape lighting. The property benefits from agricultural exemption status, keeping tax valuations lower than residential comparables while maintaining the option to pursue small-scale farming or livestock operations.
Location along Post Road in the San Marcos subdivision near San Marcos puts the property 30 minutes from downtown Austin and within the San Marcos Consolidated Independent School District - Travis Elementary, Goodnight Middle, and San Marcos High School serve the area. Texas State University sits minutes away, with downtown San Marcos shopping and dining equally accessible. The Blanco River frontage provides recreational opportunities without the restrictions of primary waterfront development.
At $791 per square foot for a 2023-built custom property with full utility independence, this represents substantial value for buyers seeking genuine self-sufficiency without isolation. This is a property built for thirty-year ownership with minimal external reliance.
