Selling mineral rights is not like selling a car or a piece of furniture. The decisions you make — and the mistakes you make — can mean the difference between walking away with fair market value and leaving tens of thousands of dollars on the table. If you inherited mineral rights from a parent or grandparent and you're now thinking about selling, this article is written for you.
By the time you finish reading, you'll understand the six most common and costly mistakes mineral rights owners make when they sell, why they happen, and exactly what to do instead. Nothing here requires a law degree or an industry background. These are practical steps that will put you in a stronger position no matter what you ultimately decide to do.
Accepting the First Offer Without Knowing What It's Worth
This is the single most common mistake, and it's easy to understand why it happens. You get an unsolicited letter in the mail — or sometimes a phone call — from a company offering to buy your mineral rights for a specific dollar amount. The number sounds reasonable. Maybe it's $8,000, maybe it's $40,000. You've never sold mineral rights before, so you have no frame of reference. The letter says the offer expires in 30 days. You think: why not?
Here's the problem. That company did its homework before it contacted you. It pulled your county records, identified that you own rights in a productive or potentially productive area, and made you an offer designed to generate profit for them — not necessarily fair value for you. The expiration date is a pressure tactic, not a real deadline.
What mineral rights actually sell for depends on several factors: whether there are active producing wells on the acreage, the current price of oil and natural gas, the formation being drilled (the Permian Basin in West Texas sells for very different prices than the Haynesville Shale in Louisiana), and what operators are paying for acreage in that specific county right now. In active Texas counties like Midland or Reeves, producing mineral rights have sold for $15,000 to $30,000 per net mineral acre or more in recent years. In Oklahoma's STACK play — the Sooner Trend Anadarko Basin Canadian and Kingfisher counties — rights have traded at a wide range depending on production. An uninformed seller might accept $5,000 per acre for something worth three times that.
The practical step here is simple: before you respond to any offer, get at least two or three competing offers. A legitimate buyer will not pressure you to sign before you've had time to think. If someone is pressuring you, that pressure itself is useful information about how they do business.
Not Understanding What You Actually Own
Mineral rights can be confusing because they're not always the same as surface rights (ownership of the land itself). You can own the minerals under a piece of ground without owning the land above it, and vice versa. When oil and gas companies talk about "mineral rights," they typically mean the right to extract oil, gas, and other subsurface resources — and those rights can be split, sold, leased, and inherited in fractions.
Many people who inherited mineral rights don't know exactly what they own. They have a deed or a letter from an attorney mentioning a fraction of an interest in a specific county, but the language is technical and confusing. Phrases like "an undivided 1/8 interest in the minerals in and under" a described tract are common — and they matter enormously when calculating what your rights are worth.
Before you sell anything, you need to know:
- What state and county your minerals are in. Rights in Lea County, New Mexico (Permian Basin) are worth far more today than rights in a non-producing county in Montana or Kansas.
- How many net mineral acres you own. This is the key unit of measure. If you own a 1/4 interest in 160 acres, you own 40 net mineral acres — not 160.
- Whether your rights are currently leased. If an operator already has a lease on your minerals, you're entitled to a royalty (a percentage of production revenue) when they produce. If you're receiving royalty checks right now, your rights are producing — and producing rights sell for significantly more than non-producing rights.
- Whether there are any title issues or clouds on the deed. More on this in the next section.
You can find a lot of this information yourself by searching the county appraisal district records (in Texas, that's the county CAD website), the county clerk's deed records, or through a service like LandWatch or a professional landman. A landman is a person trained to research oil and gas title and ownership records — think of them as a title researcher for mineral rights. Many work independently and can pull a basic ownership report for a few hundred dollars, which is money well spent before a transaction worth thousands.
Skipping the Title Review and Signing Without Clear Ownership
Title problems are far more common with mineral rights than most sellers realize. Because mineral rights are often inherited — sometimes passed down through multiple generations — ownership can become fragmented, disputed, or legally unclear. An estate may have never been formally probated. A deed may have been filed incorrectly. There may be other heirs who also own a portion of the same minerals and don't know it.
In Louisiana, mineral rights law operates differently than in other states because Louisiana uses a civil law system rather than common law. Minerals in Louisiana can revert to the surface owner if they go unleased and unproduced for ten years — a rule called the prescription of non-use. This is not the case in Texas, Oklahoma, or most other oil-producing states. If you own minerals in Louisiana, title review is especially important.
In West Virginia, Pennsylvania, and Ohio — states with active natural gas production from the Marcellus and Utica shales — there are thousands of cases of "severed" mineral rights that were separated from the surface a century ago during the coal and early oil boom. The chain of title on these older deeds can be genuinely complicated, and in some cases, the ownership has been disputed in court.
What you should do: before finalizing any sale, ask the buyer whether they will conduct a title review and whether they will handle any curative work (fixing title defects) as part of the transaction. Reputable mineral rights buyers expect to do this and will typically cover the cost. If a buyer wants to skip it or rush past it, be cautious. A title defect discovered after closing can result in the sale being unwound or in legal liability for you.
You should also review the purchase and sale agreement carefully — ideally with a real estate or oil and gas attorney before you sign. In Texas, many attorneys who handle these transactions charge a flat fee of $300–$600 to review a standard purchase agreement. That's cheap insurance on a transaction worth $20,000 or more.
Ignoring the Tax Consequences
Selling mineral rights is a taxable event, and the taxes are significant enough that they should factor into your decision.
When you sell mineral rights, the proceeds are generally treated as a capital gain — meaning they're taxed at capital gains rates rather than ordinary income rates. If you've owned (or inherited) the rights for more than one year, you qualify for long-term capital gains rates, which for most people are 15% federally. If your total income is high, that rate can be 20%, plus a 3.8% Net Investment Income Tax, bringing the federal rate to nearly 24%. On a $100,000 sale, that's up to $24,000 going to the federal government.
For inherited mineral rights specifically, there's an important rule called the stepped-up basis. When you inherit property, your cost basis (the starting point for calculating your gain) is typically reset to the fair market value at the time of inheritance — not the original purchase price paid decades ago. This can dramatically reduce your taxable gain. If you inherited rights worth $50,000 at the time of inheritance and sell them today for $75,000, your taxable gain is $25,000, not $75,000.
State income taxes vary. Texas has no state income tax. Oklahoma taxes capital gains at rates up to 4.75%. Louisiana's top rate is 4.25%. New Mexico taxes capital gains at up to 5.9%. North Dakota at 2.5%. These aren't enormous numbers, but on a large transaction they add up.
One option some sellers use is a 1031 exchange — a tax-deferred exchange that allows you to reinvest proceeds into another qualifying property and defer the capital gains tax. This is a legitimate strategy, but it has strict timelines (45 days to identify a replacement property, 180 days to close) and isn't the right move for everyone. Talk to a CPA before you sell, not after. A one-hour consultation with a tax professional familiar with oil and gas transactions can save you real money.
Signing a Contract You Don't Fully Understand
Mineral rights purchase agreements are legal contracts, and the fine print matters. Here are the specific things to watch for:
Representations and warranties. Most purchase agreements ask the seller to represent that they own what they're selling, that there are no liens or encumbrances, and that they have the authority to sell. These are standard and reasonable. But watch for overly broad warranty language that could expose you to liability years after closing if a title issue surfaces.
Purchase price adjustments. Some contracts allow the buyer to reduce the purchase price after signing if they find something during their due diligence review. A modest adjustment clause (say, for a specific title defect or an undisclosed lien) is normal. An open-ended adjustment clause that lets the buyer reduce the price for almost any reason is not acceptable — push back or walk away.
Closing timeline. Most legitimate transactions close within 30 to 60 days. If a buyer is pushing for 90 to 120 days without a clear reason, ask why. Extended timelines can work against sellers if market conditions change.
What is and isn't included in the sale. Make sure the contract clearly specifies what you're selling. Are you selling all minerals? Only oil and gas? What about any existing lease rights or royalty payments owed to you before closing? These details need to be explicit in writing.
If anything in the contract is vague, ask for it to be clarified in writing before you sign. A serious buyer will have no problem with this request. Resistance to clarification is a warning sign.
Not Getting Competing Offers — Even If You Have a Buyer You Like
Even if you've found a buyer you trust and the offer looks fair, getting at least two other competing offers costs you nothing and tells you a great deal. The mineral rights market is active, and there are dozens of legitimate buyers — ranging from individual investors to private equity-backed acquisition companies — who specialize in specific states and formations.
Here's why competition matters in practical terms. Suppose you own producing rights in Eddy County, New Mexico, and one buyer offers you $120,000. You get two additional offers: one comes in at $95,000 (now you know the first offer was reasonable), and another comes in at $148,000 (now you know the first offer was low). Without that second offer, you'd have left $28,000 on the table.
This doesn't mean chasing the highest number no matter what. A higher offer from a buyer who drags out closing, changes the terms mid-process, or has a reputation for re-trading (reducing the price after the fact) is not worth more than a slightly lower offer from a buyer who closes clean and on time. But you can only make that judgment if you have multiple offers to compare.
In Texas, Oklahoma, and Louisiana — where most of the active acquisition market is concentrated — getting three competing offers within two to three weeks is entirely realistic. In less active states like Mississippi, Alabama, or Arkansas, it may take a bit longer, but it's still worth doing.
Before you reach out to buyers, make sure you have a basic package ready: your deed or title documents (or at least the legal description of the property), any royalty statements you've received, and a clear statement of what you own. Buyers move faster and make stronger offers when the seller comes prepared.
