What to check before buying land in Burnet County

Ordered by what Burnet County's numbers point to. Every parcel differs, so treat this as where to look first.

  1. 1.Budget for a perc test and maybe an engineered septic

    USDA rates 99% of Burnet County's mapped soils "very limited" for conventional septic absorption fields and 0% "not limited".

    Without city sewer you need a septic permit from the county or state health department. Make the offer contingent on a passing soil or perc test; mound and aerobic systems can cost several times a conventional one.

  2. 2.Prove the water supply before you buy

    At least half of Burnet County was in severe drought (D2) or worse in 41% of the 262 weekly U.S. Drought Monitor maps from 2021 to 2026. Texas allocates water by permit or water right, so a well or pond isn't automatic.

    Ask whether the land has a public water connection, an existing well (and its log and yield), or neighbors' well depths from the state well database. For a new well, check permits and typical depth with the state agency first.

    Guide: Wells, public water and water rights

  3. 3.Confirm legal road access and power

    The 2020 Census classified 99% of Burnet County's land area as rural.

    Rural tracts are often sold without recorded access or a power line nearby. Get the title company to confirm a recorded easement or public road frontage, and ask the electric co-op what a line extension costs.

  4. 4.Check slope at the building site

    17% of Burnet County's mapped soils have an average slope over 15% (USDA SSURGO).

    Steep ground means grading, retaining walls, longer driveways and erosion control. Compare the slope at the house site and along the access route, not just the parcel average.

    Guide: Terrain and slope

  5. 5.Confirm the flood zone at your exact spot

    2.8% of the county's area is in the 1%-annual-chance (100-year) floodplain FEMA's National Risk Index uses for inland flooding; 1.5% of its mapped soils flood occasionally or frequently.

    Even where little of the county floods, creeks and low spots do. Check the FEMA zone at the building site and the driveway route.

    Guide: Flood zones before buying land

  6. 6.Sanity-check the price per acre

    Farm real estate in Burnet County averaged $3,738 an acre including buildings in the 2022 Census of Agriculture, and 19% of its mapped soils are prime or of statewide importance.

    Compare the asking price with recent sales of similar tracts, not the county average, which mixes cropland, pasture, timber and homesites. If an ag tax valuation applies, ask what the rollback taxes would be if you change the use.

It says how common flood-prone land is in Burnet County, not whether a given parcel floods. For that, look up the zone at your exact point on the FEMA Flood Map Service Center or run the free check.

Questions about buying land in Burnet County

How much of Burnet County, TX is in a flood zone?

About 2.8% of Burnet County's area is in the 1%-annual-chance (100-year) floodplain used by FEMA's National Risk Index (December 2025), 118th highest of 254 counties in Texas. Whether a given parcel is in a flood zone depends on its exact location, so check the FEMA map at your pin.

How much does land cost per acre in Burnet County?

The 2022 Census of Agriculture put the average value of farm land and buildings in Burnet County at $3,738 an acre, 91st highest of 254 counties in Texas (the median Texas county was $2,782). It's a self-reported average across farms, so small homesites and recreational tracts often sell for more per acre.

Will a septic system work on land in Burnet County?

Often, but test first. USDA soil surveys rate 99% of Burnet County's mapped soils very limited for conventional septic absorption fields, usually because of wetness, slow permeability, shallow rock or flooding. A perc or soil test on the parcel decides what system the health department will permit.

Is there good farmland in Burnet County?

14% of Burnet County's mapped soils are prime farmland, 0% are prime only if drained, irrigated or protected from flooding, and 5.2% are farmland of statewide importance (USDA SSURGO). The 2022 Census of Agriculture counted 1,428 farms averaging 298 acres.

How often is Burnet County in drought?

Since 2021, at least half of the county was in severe drought or worse in 41% of weekly U.S. Drought Monitor maps, and in extreme drought in 21%. On 2026-10-27, 19% of the county was in moderate drought or worse.

Can I check a specific property in Burnet County?

Yes. Enter the address or drop a pin anywhere in Burnet County on the free check. It shows which checks return data at that exact point, and the full report costs $29: flood zone, slope, soils, wetlands, roads, power lines, wildfire and more, each with its source.

Check the parcel, not just the county

County numbers tell you what to look for. The free check looks at your exact point in Burnet County: flood zone, slope, soils, wetlands, roads, power and more. The full report is $29.

What these numbers can't tell you

  • County shares describe Burnet County as a whole; a parcel can be entirely in or out of a flood zone, wetland or poor soil.
  • It doesn't look at the whole parcel, its boundaries, title, easements, zoning or permits.
  • It isn't a survey, appraisal, elevation certificate, soil or perc test, or Phase I environmental site assessment.
  • It can't see local distribution power lines, driveways, legal access, wells or mineral rights.
  • Maps lag behind the ground, and distances are straight-line, not driving distance.
