Karnes County Land and Rural Homes, Priced From the Deed Up
Ranch land, rural homes and mineral questions in Eagle Ford country, around Karnes City.
Karnes County is Eagle Ford country, and the deed shows it
Karnes County land for sale comes with a question most buyers from outside South Texas never think to ask: who owns what's under it? Karnes County is one of the places in South Texas tied to Eagle Ford Shale activity, and mineral rights come up on nearly every rural sale here.
Across rural Texas, minerals were often separated from the surface generations ago. A ranch with its minerals and a ranch without them are two different properties, even when the fences, the house and the pasture look identical from the county road. Mineral ownership changes how a property prices, how it gets marketed, and what a buyer needs to see before writing an offer.
We're James Peterson ALC and Barbara Peterson, brokers and owners of Texas Ranch & Home, the United Country Real Estate franchise in Floresville. Karnes County is one of the five South Texas counties we work. The other four are Wilson, Atascosa, Gonzales and Guadalupe. We've sold rural homes and land together for 30 years, roughly 2,000 properties across that territory.
This page covers what's different about buying or selling land in Karnes County, how we work it, and where to go next for your situation. If your property sits in or right around town, our Karnes City page covers the in-town side of the market.

One 120-acre ranch, and the 75% nobody knew about
Here's a Karnes County sale that shows the problem better than any explanation. A seller listed a 120-acre ranch believing the mineral rights came with it. During title review, it turned out earlier family members had sold 75% of the minerals decades before.
The buyer still went forward. The purchase price changed significantly once the real mineral ownership was confirmed. Nobody set out to mislead anybody. The sale had happened a long time ago, and it was sitting in the chain of title where nobody in the family had looked.
For a Karnes County seller, the lesson is to find out what you own before you set a price. Pull your prior deeds. Gather your royalty statements if you receive any. Confirm your ownership percentages and talk to a title company early. A fact found before listing costs far less than the same fact found in the title commitment with a buyer waiting.
For a buyer, it runs the other way. Ask whether the seller owns any minerals and how much. Ask whether there's an active oil and gas lease and whether royalties are being paid. Then have a title company confirm it. We walk through the full list in do mineral rights transfer with property sales in South Texas.
Surface-only is normal. Pricing it like it isn't is the mistake.
A surface-only sale means the buyer gets the land, the improvements and the access. The buyer also gets the right to farm, ranch, hunt and build. The oil, gas and other minerals stay with someone else. In a lot of rural Texas, it's the most common kind of land sale there is.
Surface-only doesn't mean less useful. A buyer who wants a homesite, a pasture for cattle or a place to hunt may get everything they need from the surface. Land with minerals included often brings a higher price, and a listing has to be clear about which one it is.
Texas law treats the mineral estate as dominant over the surface. The mineral owner or a company leasing from them can use the surface reasonably for roads, pipelines, drill sites and equipment. Some mineral owners have signed agreements limiting surface use, which can help protect a homesite, a water well or other improvements. On a Karnes County tract, we look for those documents before a buyer falls in love with the place.
How we work Karnes County from Floresville
We split the work the way properties split. James Peterson ALC leads farm, ranch and acreage sales under the UC Ranch Properties name. He's an Accredited Land Consultant, certified to conduct broker price opinions, and a licensed drone pilot. Barbara Peterson leads homes, including homes in town and in small communities. She also leads VA and Texas Veterans Land Board buyers, probate and military sales.
Before we talk price on a Karnes County property, we drive it. We look at the entrance and the road frontage. We look at the fences, the water and how much of the acreage is usable. We also look at what the mineral side has already put on the surface, such as lease roads, pipelines and drill sites. Then we price the land, the home and the improvements, separately and together. Here's how the pricing step works.
A Karnes County listing doesn't only go where homebuyers look. It goes on the MLS, the Land Broker Co-op, the RLI land network and both of our websites. It carries drone video and on-site video. Sierra Glenn sold 15 acres with us in April 2026: "Our 15 acre property sold in 11 days! And that quick sale was all due to their hard work. They took photos, a drone video, made social media videos, sent out real estate Eflyers that reached thousands in 24 hours." Not every property sells that fast, and we won't promise yours will.
What changes hands in Karnes County
Karnes County property doesn't sort into neat categories. Most of it is some of both: land with a house, a ranch with a lease road or a hunting tract with a barn. These are the situations we see most, and each has its own page.
- Farms and ranches. Agricultural use, ag valuation and mineral ownership decide most of the number. Selling a farm or ranch in Karnes County.
- Hunting and recreational tracts. Legal access and surface use matter as much as the habitat. Hunting and recreational land in Karnes County.
- Inherited land. Minerals and surface can be split among heirs over several generations, and the title has to be sorted before the sale. Probate and estate sales in Karnes County.
- Rural homes on acreage and in small communities. Barbara's side of the business, where the house and the land are priced together.
- Larger tracts that may sell better as smaller pieces, if the access, frontage and county rules support it.

Frequently Asked Questions
Do mineral rights come with land I buy in Karnes County?
Only if the seller owns them and the contract and deed include them. A seller may own all of the minerals, a partial interest or none at all. They may also have them leased to an oil and gas company. The deed, the contract and the title commitment spell out what transfers. Read the exceptions in the title commitment carefully, because mineral reservations often sit there.
Can I sell my Karnes County land and keep the minerals?
Yes. A Texas seller can reserve some or all of the mineral rights when selling the surface, and the reservation has to be written into the deed. Keeping the minerals affects the price and which buyers are interested. We talk it through before the listing goes live, so the property is priced and described for what is actually being conveyed.
Is surface-only land worth buying?
It can be, depending on what you want the land for. Buyers looking for hunting, grazing or a homesite often get what they need from the surface alone. Land with minerals included often brings a higher price. Before closing, understand that the mineral owner can use part of the surface reasonably, and look for any recorded agreement that limits that use.
