Why this one
Used as a weekend place for a handful of visits. Everything from the quartz counters to the aerobic septic is in its first years of life.
Drilled to 600 feet with 2,000 gallons of storage. Shallow Hill Country wells struggle in August; this one was built not to.
Mature live oaks around the house, open ground beyond. Enough acreage to qualify for Blanco County's agricultural valuation through beekeeping over time.
Private community access for swimming and fishing, without a waterfront premium. The house itself sits about 80 feet above the river.
About an hour from Austin or San Antonio, 25 minutes to Dripping Springs, 8 minutes to downtown Johnson City.

True cost of ownership
No water or sewer bills, a $250 HOA, and acreage that qualifies for Blanco County's agricultural valuation through beekeeping: six hives on five to ten acres, kept seven months a year. The county requires five years of ag use before the lower valuation applies, so this is a long-hold benefit, not a first-year one.
| Annual cost | Today | After 5 years of ag use (est.) |
|---|---|---|
| Property tax 2026 bill on $490,490 assessed value | $6,632 | ≈ $4,800 |
| HOA (Pedernales Bend, includes common grounds and river access) | $250 | $250 |
| Water bill | $0 (private well) | $0 |
| Sewer bill | $0 (aerobic septic) | $0 |
| Septic maintenance contract | ≈ $300 | ≈ $300 |
| Fixed annual carrying cost, before insurance and utilities | ≈ $7,180 | ≈ $5,350 |
Ag estimate assumes about 5.1 acres qualify (the acre around the house stays at market value), land market value near the county's $167,830 assessment, and the current combined tax rate of about 1.35%. That removes roughly $135,000 of taxable value, saving about $1,800 a year once qualified. The land is not currently under ag use, so a buyer who starts beekeeping on closing would qualify after five years of documented use (Texas Tax Code 23.51). Blanco CAD confirms eligibility. This is an estimate, not tax advice.
Country systems, explained
Drilled to 600 feet, the deepest well the owners know of nearby, so it draws from well below the seasonal table. The well fills a storage tank, so pressure and supply stay steady through a dry stretch. No water bill.
A large concrete tank treats wastewater and sprinklers distribute it. Standard in the Hill Country; a yearly service contract keeps it inspected.
Runs the gas cooktop. Heat and cooling are electric central systems.
Improved all-weather road to a gated entry. Electricity and propane connected; internet via Hill Country Wireless today, with Starlink available at the address.

Questions buyers ask first
From the owners
We built this as our weekend place and only ever made it out for a handful of them. The best part was always the same: string lights on, fire going under the big oak, and more stars than we knew were up there. It deserves someone who will use it every week.
