How to Spot a Lowball Offer

Not every low offer is a scam, but a specific pattern of language on the purchase agreement tells you whether the buyer in front of you is the one who will actually close.

Mailbox offers arrive by the dozen once a well near your tract gets permitted, and the spread between the lowest and highest can run wide for the exact same interest. Some of that spread is legitimate difference in decline assumptions. Some of it is a buyer pricing in the fact that they never intend to hold what they're buying, and that distinction shows up in the paperwork before it ever shows up in the check.

This is what to check before you sign, starting with the one clause that tells you the most.

The 'and/or assigns' tell

Look at the signature block and the buyer definition on the first page of the purchase and sale agreement. If the buyer is named as 'Buyer, and/or its assigns' or similar wording, the entity signing your deed may resell your interest to someone else before the deed is even recorded, or immediately after, at a markup they never disclose to you.

That clause is not automatically bad faith, plenty of legitimate transactions include assignability language for tax or entity-structuring reasons. But paired with a rock-bottom offer, it is often the anatomy of an assignment shop: a buyer with no intention of holding the minerals, whose entire margin is the spread between what they pay you and what they resell for within days or weeks.

Ask who is actually funding the closing

A direct buyer acting as principal can tell you plainly that the funds at closing come from their own account and that they intend to hold the interest, because there is no assignment planned. An assignment shop will often deflect this question or answer it vaguely, because the honest answer undercuts the offer they just made you.

You are entitled to ask this before signing anything. A buyer unwilling to answer directly is telling you something.

Compare the offer to your own royalty history

If your interest is producing, you have the best comp sitting in your own mailbox: the last twelve to twenty-four months of royalty checks. An offer that looks reasonable against a national multiple but ignores your specific decline curve, recent workover activity, or a new well added to your unit is a red flag regardless of who is making it.

Ask the buyer to show their math, tied to your actual production history rather than a generic acreage figure. A buyer confident in their number will show the work; one relying on you not checking usually won't.

Watch for artificial urgency

'This offer expires in 48 hours' on a mineral interest that has sat under your name for years is a pressure tactic, not a market reality. Legitimate buyers understand that sellers want time to compare offers or talk to family, and a deadline that short is designed to prevent exactly that comparison.

A real decline in value over 48 hours essentially never happens outside of a specific, disclosed drilling event. If a deadline is paired with vague reasoning, treat it as a signal to slow down, not speed up.

Questions From the Acquisition File

Owner questions

Plain answers on title, production, pricing, and timing, so the purchase terms hold no surprises.

Does 'and/or assigns' language always mean the offer is a lowball?

No, it appears in many legitimate contracts for structuring reasons, but combined with an offer well below your own royalty comps or a rushed deadline, it is a pattern worth asking direct questions about before signing.

How do I know if an offer is actually competitive?

Compare it against your own trailing royalty checks if the interest is producing, and against recent lease bonus or permitting activity in your section if it is not, rather than against a flat multiple that ignores your specific tract.

Should I get more than one offer before selling?

Comparing offers is reasonable and a buyer confident in their pricing should not discourage it, though a documented, math-backed offer from one direct buyer can be worth more than several unexplained low numbers from mailers.

What should I ask before signing any purchase agreement?

Ask who the named buyer is, whether they intend to hold or resell the interest, how the price was calculated, and whether the closing timeline is negotiable, and expect straight answers to all four.

Are lowball offers illegal?

Not typically, a low offer on its own isn't unlawful, buyers are free to offer what they choose, but misrepresenting who the buyer is or pressuring a signature through deceptive urgency can cross into practices worth reporting to your state's attorney general or land office.

Why do some mailers arrive addressed strangely or with an unfamiliar company name?

This often reflects an assignment shop operating under a shell entity created for a specific batch of mailers, which is itself a signal worth weighing alongside the offer amount and the assignability language in the agreement.

Should I ignore every mailer offer automatically?

No, not every mailer is a lowball, but treat each one with the same checklist: named buyer, funding source, and reasoning tied to your actual production, rather than assuming any single source is automatically trustworthy.
