Got an Unsolicited Offer?

The letter says act now, the number looks round, and there's no comp attached anywhere in the envelope.

Mineral owners across active plays regularly receive unsolicited mail, postcards, and phone calls offering to buy their interest, usually sourced from county deed or probate records rather than any special knowledge of that specific tract. Getting one of these is not itself a red flag; it is simply how a large share of this market sources deals. The mistake is treating the first number in that envelope as the market price rather than as a single data point to be checked against others.

Why the first number is rarely the best number

Buyers who mail broadly to courthouse lists are optimizing for volume and reaching owners who might not otherwise think to sell, and their initial number is frequently set low enough to leave room for negotiation, or low enough that only owners who don't check comps will accept it outright. This does not make the buyer dishonest, only that mailer pricing tends to sit at the low end of what the interest could actually fetch with a bit of comparison shopping.

Some mailers are set up more carefully, using actual county-level comps and decline-curve estimates on producing interests, and those tend to be closer to a fair opening number. The only way to tell the difference is to ask the buyer to show their work and compare it against at least one other quote.

How to benchmark the offer

Start with what you actually own: pull your most recent division order or royalty statement if the interest is producing, or the deed establishing net mineral acres if it isn't. Ask the buyer who sent the offer to explain how they arrived at their number, specifically what comps or decline-curve assumptions they used, and note whether they can name recent sales in your specific county and unit rather than a generic regional figure. Then contact at least one other acquisition desk, ideally one that works actively in your county, and ask for a competing quote using the same information.

If the second quote lands meaningfully higher, that gap tells you the first offer had room in it. If the two quotes land close together, that's a reasonable sign the market for your specific interest is roughly where both buyers say it is.

Questions to ask before responding at all

Ask how the buyer got your name and address, since a buyer citing a specific probate filing or deed record is being straightforward about their sourcing, while a vague answer is worth noting. Ask whether the quoted price is firm or subject to change after their own title review, since some offers are deliberately set high to get a signature, then reduced after a curative issue is found or invented. Ask what the deadline pressure in the letter actually means in practice, since a legitimate buyer's price rarely expires in the handful of days a mailer sometimes implies, and a real deadline should be explainable in plain terms.

It's also fair to ask the buyer directly whether they'd match or beat a competing quote, since some will and some won't, and the answer itself tells you something about how much room was built into the original number.

When the unsolicited offer turns out to be fair

Not every mailer offer is lowball. Some owners with small, hard-to-manage interests find that a straightforward mailer offer, once benchmarked against a second quote, is genuinely reasonable, and the convenience of a buyer who already did the outreach work can be worth accepting rather than shopping further. The point of benchmarking isn't to assume every unsolicited offer is bad, only to know, with an actual comparison in hand, whether it is.

A useful habit is keeping every unsolicited letter you receive, even ones you don't act on, since the range across several offers over time tells you more about where the market actually sits than any single number does, and that history becomes useful leverage whenever you do decide to sell.
