What Surveys and Inspections Do You Need When Buying Acreage in Texas?

Buying acreage in Texas requires a boundary survey, a title commitment reviewed for easements and mineral reservations, a septic (OSSF) evaluation, a water-source test, and a structural inspection of any improvements. A residential home inspection alone is not enough. The land itself is the asset, and most of what can go wrong on rural property is invisible from the driveway.

That is the short answer. The longer answer is that rural due diligence is a sequence, not a checklist — each step changes what the next step needs to cover. At The Agency Dallas, our approach to buying acreage in Texas is to order the survey first, because the survey determines whether the rest of the inspections are even measuring the right ground.

Why is a survey the first thing you order when buying acreage?

Because rural tracts are described by metes and bounds, not by a platted lot number. A subdivision lot is defined by a recorded plat that a title company can read with certainty. A 43-acre tract is defined by a written description that traces the boundary in directions and distances from a starting point — and those descriptions are frequently decades old, written from monuments that have since been removed, and inconsistent with where the fences actually sit.

A current boundary survey tells you four things a title commitment alone will not:

• The true acreage. Fenced acreage and deeded acreage differ often enough that the TREC Farm and Ranch Contract (Form No. 25-16, adopted under 22 TAC §537.32) includes an option to adjust the sales price based on the acreage the survey reveals. That option exists because the discrepancy is common.
• Where the boundary actually runs relative to the fence line, the barn, the driveway, and the neighbor's improvements.
• Encroachments in both directions — a neighbor's outbuilding on your side, or your seller's pens on theirs.
• The physical location of every easement listed in the title commitment: utility, pipeline, access, drainage.

On price: a boundary survey for a single residential acre typically runs $500 to $1,000. Larger tracts are priced per acre and drop sharply with scale — roughly $70 to $140 per acre for sites in the 50-to-100-acre range. Complex rural and ranch surveys with heavy tree cover, irregular boundaries, or missing monumentation commonly land at $1,000 to $3,000 or more. An ALTA/NSPS survey, which is the commercial-grade product lenders request on higher-value or income-producing land, runs from roughly $3,000 to $25,000 and up in Texas depending on acreage and complexity.

By Texas custom, the seller pays for the owner's title policy and the buyer pays for the survey when no acceptable existing survey is available. That custom is negotiable and frequently negotiated.

What inspections does acreage need that a suburban house does not?

A house on a city lot is connected to municipal water, municipal sewer, and a utility grid that someone else maintains. Acreage usually is not. Every one of those systems becomes a private asset you are buying, and each one needs to be evaluated separately.

Order these in addition to a standard home inspection on any improvements:

1. Septic / OSSF evaluation. On-site sewage facilities are permitted through the county or an authorized agent. Ask for the original permit and the system design, confirm the tank and drain field locations, and have the system inspected and pumped. A failed conventional system on unsuitable soil can require an aerobic replacement.
2. Water source and well test. If the property is on a well, test for flow rate (gallons per minute) as well as potability — a well that tests clean but produces two gallons a minute will not run a household plus livestock. If the property is on a rural water supply corporation, confirm a meter exists or what a new tap costs, because tap fees on some North Texas systems are substantial and the waiting list can be long.
3. Soil and percolation testing where you intend to build. Soil determines the septic system type, the foundation design, and in many cases whether a homesite is viable at all.
4. Floodplain and drainage review. Pull the FEMA panel, then walk the low ground after rain if the calendar allows. A creek that is a feature in August is a different proposition in May.
5. Access verification. Confirm legal, recorded access to a public road. A driveway that has been used for thirty years is not the same as a recorded easement, and lenders will not accept the former.
6. Structural inspection of outbuildings. Barns, shops, pens, and loafing sheds are rarely covered in a standard residential inspection scope unless you ask for them by name.
7. Fence-line walk. Walk the full perimeter against the new survey. This is where the survey earns its fee.

What does the title commitment tell you about acreage that it does not tell you about a house?

Two things dominate rural title review: easements and mineral rights.

Easements on acreage are more numerous and more consequential than on a platted lot. Pipeline easements can restrict where you build and what you plant. Utility easements can carry maintenance access rights across the middle of a pasture. Shared-access easements can obligate you to a road-maintenance arrangement with neighbors you have not met. Every easement in Schedule B of the commitment should be located on the survey — an easement you cannot see on a map is an easement you do not understand.

Mineral rights in Texas are routinely severed from the surface estate, and the mineral estate is dominant, meaning the mineral owner has the legal right to reasonable surface use to reach their minerals. Ask three questions: what mineral interest is being conveyed, what is reserved, and is there an existing lease. A surface-only purchase is entirely normal in Texas and not automatically a problem — but it should be a known fact at contract, not a discovery at closing.

Also check the ad valorem tax status. If the tract carries a 1-d-1 agricultural valuation, find out what activity supports it and what happens to that valuation under your intended use. Rollback exposure is real money.

What is the right order of operations?

The sequence matters more than the list, because each item gates the next:

1. Execute the contract with a realistic option period — rural due diligence takes longer than suburban due diligence, and surveyors in North Texas book out.
2. Order the survey immediately. It has the longest lead time of anything on the list.
3. Order the title commitment and read Schedule B line by line.
4. Schedule the septic evaluation and the well test.
5. Run the home and outbuilding inspections.
6. Overlay the survey against the title commitment, the FEMA panel, and the inspection findings.
7. Negotiate or terminate before the option period expires.

Buyers who compress this into a standard ten-day residential option period are the buyers who close on surprises. A firm that handles acreage regularly builds the option period around the survey lead time, not the other way around. That is the single most useful thing The Agency Dallas does for clients buying acreage in Texas: setting the timeline so the diligence actually fits inside it.

Water is its own subject and a large one — if the property has a pond, a creek, or a well you intend to rely on, read our companion piece on how water rights work when purchasing a Texas ranch before you write the offer. You can also see how we work with land and ranch buyers on our land and ranch page.

Buyers comparing acreage against other North Texas options often have two other questions running in parallel: how builder phase pricing and lot premiums work in new communities, and how to analyze a Dallas rental property before making an offer if the land purchase is part of a broader portfolio decision.

Frequently asked questions

Do I need a new survey if the seller already has one?

Often the existing survey is acceptable, particularly if it is recent and nothing has changed. Your title company and lender decide. If they accept it, the seller signs a T-47 affidavit confirming no changes since it was made. If improvements, fences, or boundaries have moved, order a new one.

How long does a rural survey take in North Texas?

Plan for two to four weeks from order to delivery, and longer in spring when surveyors are busiest and wet ground slows fieldwork. Heavy tree cover, large acreage, and missing corner monuments all extend the timeline. Order it the day the contract is executed rather than midway through the option period.

Is a septic inspection required by law when buying acreage?

It is not universally required by statute, but lenders frequently require it, and county rules vary. Treat it as mandatory regardless. Replacing a failed on-site sewage facility is a five-figure expense, and the condition of the system is not something you can assess by looking at the yard.

What happens if the survey shows less acreage than the listing said?

The TREC Farm and Ranch Contract contains an optional provision allowing the sales price to be adjusted based on the acreage the survey establishes. Whether that provision was selected is determined when the contract is written — which is precisely why the question belongs in the offer conversation and not in the option period.

Should I use a residential home inspector for a property with a barn and a well?

Use a residential inspector for the house and add specialists for everything else. Standard inspection agreements exclude outbuildings, wells, and septic systems unless specifically added. Confirm scope in writing before the inspection is scheduled, not after the report arrives.
