Land due diligence in the Texas Hill Country.
The Hill Country is the most-listed and least-understood land market in Texas. Views sell the tract; water, soil and recorded restrictions decide whether you can actually build on it.
Across Hays, Blanco, Comal, Gillespie, Kendall and western Travis counties, the constraints repeat even though the counties differ. There is no countywide zoning, so the rules that bind a tract are recorded ones — deed restrictions, subdivision covenants, easements and reservations — plus county septic permitting, groundwater district rules and floodplain mapping that apply regardless of what a listing calls 'unrestricted'.
Water is the first real question on nearly every tract. Wells draw on the Trinity or Edwards systems, yields vary sharply over short distances, and groundwater conservation districts govern permitting and spacing with different rules on each side of a county line. Groundwater is a severable property right in Texas, so we confirm from the deed records whether it conveys at all before looking at any well.
Soil and terrain do the rest. Karst limestone and thin caliche soils make on-site sewage siting hard and sometimes force an expensive engineered system. Creeks that are dry ten months a year carry the flash floods this region is known for, and mapped floodplain along them removes usable area a buyer priced into the deal.
Then there is the tax picture. Most Hill Country acreage sits under a 1-d-1 agricultural or wildlife valuation, which is why the advertised tax bill looks small. Change the use and the appraisal district can recover up to five years of the difference plus interest. That rollback belongs in the contract negotiation, not in a surprise at closing.
If you want the underlying method rather than the local version, start with our complete land due diligence guide or the free 47-point checklist.
County clerk deed records for the governing county
Deeds, restrictions, subdivision covenants, easements, and mineral or groundwater reservations for the tract — pulled as recorded instruments and read in full, not summarized from an index entry.
Central appraisal district for the county
Deeded acreage, appraised value and any 1-d-1 agricultural or wildlife valuation on the parcel, with rollback exposure quantified against the recorded history.
Groundwater conservation district rules
Which district covers the tract — Barton Springs/Edwards Aquifer, Hays Trinity, Blanco-Pedernales, Cow Creek and others all differ — and what its permitting, spacing and production rules require for a new well.
County OSSF permitting, FEMA mapping and TCEQ data
On-site sewage facility authority and soil constraints, mapped floodplain along the creek systems, and Edwards Aquifer recharge-zone status where it applies.
City ETJ boundaries
Whether the tract falls inside the extraterritorial jurisdiction of Dripping Springs, Wimberley, Boerne, Fredericksburg, New Braunfels or Austin, and what that adds to platting and development review.
We work from these records remotely — no site visits, no survey, no brokerage. Our completed reports so far are concentrated in Texas and Pennsylvania; the records workflow is the same one we apply to a the Texas Hill Country parcel, and every source is cited so you can check it yourself.

the Texas Hill Country questions we get
Which counties does your Hill Country review cover?
Hays, Blanco, Comal, Gillespie, Kendall and western Travis most often, and neighboring counties on request. The research method is the same everywhere; what changes is which clerk, appraisal district and groundwater district holds the record, and we identify those for your specific tract.
Can you confirm a Hill Country tract will have water?
We confirm what the record can prove: whether the groundwater rights convey, which conservation district regulates the tract, and what its permitting and spacing rules require. Actual yield only comes from a driller's test — where the record raises doubt, we tell you to make that test a contract condition.
The listing says the land is unrestricted. Is that true?
It usually means there is no county zoning, which is a different statement. Recorded deed restrictions, subdivision covenants and easements still bind the land, and septic permitting and floodplain rules apply either way. We pull the recorded instruments and read them.
How much of the ag rollback will I owe?
That depends on the valuation history and the county's assessment, and it is one of the specific items the report quantifies from appraisal district records so you can negotiate it before you sign rather than absorb it after.
Do you visit the property?
No — Landisle is a records-based practice working from deeds, plats, GIS, agency data and code text. Where a question can only be answered on the ground, the report says so and tells you precisely what to have a local surveyor, driller or septic designer check.
