Got an Offer to Buy Your Mineral Rights? How to Tell If It’s Actually Fair

A letter shows up. Sometimes a text. The number looks big — five figures, maybe six — and there’s a deadline at the bottom.

Before you sign anything, understand this: in the past 36 months, Valor has recovered more than $27 million for mineral owners who thought their records, payments, or offers were in order and found out they weren’t. Unsolicited purchase offers are one of the most common moments owners get this wrong.

You’re not alone, either. Mineral owner forums are full of owners posting purchase offers right now and asking strangers, “Is this fair?” — from Custer County, Oklahoma to Marshall County, West Virginia to North Dakota. Oklahoma and Texas owners especially are seeing landmen pitch leases and outright purchases in the same letter. The crowd can offer sympathy. It can’t pull your title, check your decimal, or run your unit’s undeveloped locations.

This post walks through how buyers actually price an offer, the difference between leasing and selling, the red flags that should slow you down, and the questions to ask any buyer — before you cash a check you can’t undo.

Why You’re Getting an Offer in the First Place

If a buyer is mailing you, they already know something about your tract. They’ve pulled county records, cross-referenced production data, and run an economic model. They are not guessing.

Buyers source offers from public well data and state filings across the 13 major basins where mineral transactions are most active — Texas, Oklahoma, New Mexico, Louisiana, Colorado, Wyoming, North Dakota, Pennsylvania, West Virginia, Ohio, Utah, Montana, and Kansas. Valor manages mineral assets across all 13. The same datasets buyers use to make you an offer are the datasets a good mineral management partner uses to evaluate it.

The practical takeaway: an unsolicited offer is a signal that someone with better data than you thinks your minerals are worth more than they’re paying. Your job is to figure out how much more.

How Buyers Actually Value Minerals

Most mineral buyers price an offer using some version of the same three-part model:

• A multiple of recent cash flow. Producing minerals are typically valued at 36 to 60 months of trailing royalty income, adjusted for decline. If your check averaged $500/month last year, expect the producing-piece of an offer to land somewhere between $18,000 and $30,000.
• Undeveloped upside. This is where buyers make their money. If your tract sits inside a unit with permitted-but-undrilled locations, or near offset operator activity, the buyer prices that in — and keeps it. You won’t see it as a line item.
• A discount for the commodity strip. Buyers run their model against forward oil and gas prices, then knock 20-40% off to protect their return.

The offer you see is the residual after the buyer takes their margin. That doesn’t make the offer bad. It means the headline number isn’t the right comparison — the right comparison is what those same minerals will pay you over the next 10 to 20 years.

Lease Bonus vs. Outright Sale — They Are Not the Same Decision

Owners routinely conflate these. They are fundamentally different transactions — and it’s the single biggest point of confusion in the forum threads we see.

A lease bonus is an upfront payment for the right to drill during a primary term, typically three years. You keep your mineral interest. If the operator drills and produces, you receive a royalty — usually 1/8 to 1/4. If they don’t drill, the lease expires and you can lease again.

An outright sale ends your ownership. Forever. Every well drilled after closing — by this operator or any future one, on this formation or any deeper one — belongs to the buyer. In stacked-pay basins, that can mean giving up Wolfcamp, Bone Spring, Spraberry, Woodford, and Meramec economics in a single signature.

If a buyer’s letter uses “lease” and “purchase” interchangeably, or the document says “Mineral Deed” but the cover letter calls it a “leasing opportunity,” stop reading and have someone qualified look at it.

Red Flags in the Offer Letter Itself

Buyer tactics are consistent enough to pattern-match. Watch for:

• “All your right, title, and interest” with no depth limitation, formation carve-out, or specific tract description. This is the broadest possible grant. You may own more than you think — and signing this conveys all of it.
• Short deadlines. 72 hours, 7 days, “this offer expires Friday.” Legitimate buyers will give you time for title and tax review. Pressure is a tell.
• One round number, no math. If there’s no breakdown of producing vs. non-producing value, the buyer is hiding the upside calculation.
• A check mailed with the deed. Cashing the check can constitute acceptance in some states. Do not deposit anything until the transaction is reviewed.
• No title work shared. The buyer has run title on your tract. Ask for it. Most won’t share it — which tells you what it’s worth.

Valor’s land and accounting team — CPAs, CPLs, and CMMs — reviews offers like these regularly. The team exists because the documents are written by professionals and the owners receiving them usually aren’t.

Questions to Ask Any Buyer

A serious buyer can answer all of these. An opportunistic one will dodge most of them:

• 1. How did you arrive at this number? Ask for the split between producing value and undeveloped upside.
• 2. What multiple of my trailing royalty income is this? If they won’t say, divide the offer by your average monthly check.
• 3. Is this a purchase or a lease? Get it in writing.
• 4. Does this include all depths and formations, or is it limited? If they’re buying everything, they should pay for everything.
• 5. What permits or rig activity do you see in or near my unit? They know. Make them tell you.
• 6. Will you share your title work? If they won’t, assume it tells a story favorable to you.
• 7. What’s the deadline, and why? Anything shorter than the time it takes to get an independent valuation is a pressure tactic.

When Selling Makes Sense — and When Holding Does

Selling minerals isn’t inherently a bad decision. A sale can be the rational move for estate planning and simplification, for diversification when minerals are an outsized share of your net worth, for life events that put the capital to better use, or for small non-producing interests where the paperwork outweighs the value.

Holding tends to win when your unit has undeveloped locations, new permits, or active offset drilling — the upside the buyer is pricing in belongs to you if you keep it. It also wins in stacked-pay basins, where today’s producing formation may not be the most valuable one under your tract, and when your royalty income is stable or growing. And if the offer arrived unsolicited with a deadline, remember: the timing is the buyer’s, chosen because they see something. There’s rarely a penalty for slowing down.

The mistake isn’t selling. The mistake is selling without knowing what you have.

What to Do Before You Sign Anything

The right sequence is almost always the same:

1. 1. Pull your last 12-24 months of royalty statements. Calculate your average monthly net.
2. 2. Identify the operator, the unit, and the producing formations.
3. 3. Check for new permits, recent completions, or undeveloped locations inside your unit.
4. 4. Verify your decimal interest matches what the operator is paying you on. Underpayment is one of the most common ways Valor has recovered owner funds.
5. 5. Get a second valuation. Even a rough one from a qualified party tells you whether the offer is in the ballpark.
