Buying land here
Land along the Pedernales is not turnkey.
Buying land is materially different from buying a built home. The price is lower, but the work is heavier. You are signing up for: site planning, well drilling and verification, septic system design and permitting, FEMA floodplain analysis, county building code review, electrical service installation, road and driveway construction, and either custom build management or pre-fab placement.
For experienced Hill Country builders this is straightforward. For first-time land buyers from Austin it can be a learning curve. The best path forward is to talk through the build sequence with someone who has done it on the river before, ideally before you commit to a specific parcel.
Pedernales land prices vary widely. Spicewood and Briarcliff subdivision lots with city water and sewer hookup, paved access, and existing utility runs typically price $400K to $1M for 1 to 5 acres. Larger off-grid acreage in the Johnson City corridor can be found from $300K for 10 to 25 acres without river frontage, scaling up to $2M+ for 50+ acre tracts with river frontage and ranch infrastructure.
For raw river-frontage land specifically, expect $400K to $1.5M for 5 to 25 acres depending on frontage quality, location, and county. The same money buys very different land profiles in Travis County (smaller, closer to Austin) versus Burnet County (larger, more rural).
