Two numbers can exist for the same interest at the same moment, and neither one is wrong. They are just answering different questions.
Owners come to this question expecting a single figure, and the honest answer is that mineral value depends heavily on which lens you are asking about. An appraisal, done properly, produces a documented opinion tied to a stated purpose and effective date. A purchase offer produces a number a specific buyer will actually pay, today, in cash, given their own read on risk. Confusing the two leads to either disappointment when a buyer's offer comes in below an estate appraisal, or frustration when an owner expects a market offer to match a number built for tax purposes years earlier.
A formal appraisal, prepared for estate, IRS basis, or litigation purposes, is anchored to a specific date and a specific standard of evidence. For producing minerals, that mostly means the decline curve built from royalty statement history, discounted at a rate reflecting commodity and operator risk. For undeveloped acreage, it leans more on comparable transaction data or a probability-weighted view of future development, which is inherently more speculative and should be labeled as such in the report.
Because it is dated, an appraised value can diverge sharply from current conditions. An interest appraised at the date of an owner's death in a strong commodity price environment may carry a materially different value than the same interest would show if reappraised today, and that is expected, not an error, since the report is answering what the interest was worth on that specific date, not what it would fetch now.
A cash offer reflects present conditions and a specific buyer's portfolio. It moves with commodity strip pricing, with how active the operator has been recently on your unit or adjacent units, with whether the well is early in its decline or well into a flattened tail, and with how clean your title and division order paperwork is. Interests with gaps in the chain of title, unresolved heirship, or missing division orders typically see offers discounted to account for the buyer's own cost of clearing that paperwork before the sale can close.
Buyers also price in liquidity and time. An owner who needs to close quickly for estate settlement reasons and an owner who is willing to wait and shop the interest to several buyers over months are often looking at different numbers from the same buyer, because urgency and negotiating leverage are themselves part of the price.
The gap tends to be narrowest on strong producing wells with clean, recent records, where both the appraiser's income-approach math and the buyer's underwriting are working from largely the same decline curve. The gap widens on undeveloped or shut-in acreage, where an appraiser might apply a probability-weighted development scenario that a buyer, pricing real cash today rather than a future possibility, discounts more heavily.
It also widens whenever the appraisal's effective date sits far from today. A report dated during a commodity price spike will show a higher figure than current offers if prices have since eased, and the reverse is true as well. Neither number is dishonest. They are simply measuring different moments and different purposes, which is exactly why an estate attorney or CPA will insist on a dated appraisal rather than accepting a current offer as a substitute for basis purposes, and why your CPA is the right person to confirm which figure applies to your specific tax situation.
If you need a documented, dated opinion for an estate, tax, or legal purpose, that work belongs with a credentialed appraiser, and having your deed history, division orders, and royalty statements organized in advance, as covered in our documents checklist, will materially speed that process and lower the cost. If instead you want to know what a buyer would pay today, sending the same records through our get an offer page gets you a specific figure without the wait a formal report requires.
Resolve these questions so the appraisal conclusion can be traced to a defined interest, date, method, and evidence set.
The appraisal, dated to the required effective date, is what basis and estate filings rely on. A current cash offer is not a substitute, and your CPA should confirm the specific date and standard needed.
Commodity conditions, decline curve progression, and the time elapsed since the appraisal's effective date all move the number. An older appraisal reflects a past moment, not current market conditions.
No. Producing interests lean on royalty history and decline curves, while undeveloped acreage typically relies more on comparable sales or probability-weighted development assumptions, which carries more uncertainty.
Yes. Buyers factor in the cost and time of clearing title issues or tracking down missing division order paperwork before closing, and that typically shows up as a discount in the offer.
Carry the same effective date, interest definition, evidence hierarchy, and limitations into these related appraisal procedures.
