How to Tell If a Business Owner Will Actually Sell

The most expensive company in a search is usually the one you spend five months on before discovering the owner was never going to sign anything. Overpaying, at least, leaves you with a business.

That failure mode has a name in the literature. Stanford Graduate School of Business, in the 2026 edition of A Primer on Search Funds, describes it as the risk of becoming an unpaid consultant:

A critical step in the deal sourcing process is qualifying sellers; that is, to determine if the company is truly an attractive target and if the owner is willing to sell in the near term. With limited resources, a search fund cannot afford to spend time, money, and energy getting to know a company, only to find out the owner is not truly committed to a sale but is instead looking for a free valuation service from a smart MBA investor.

— Primer, p. 33

Qualifying an owner is a skill, and it is mostly a matter of knowing which signals mean something and which ones are noise. Here is what the research says, organized by how early you can observe it.

The two questions that are not the same question

Buyers routinely collapse "is this a good business" and "will this owner sell" into a single judgment. They are independent, and they fail independently.

A company can clear every financial screen you have — the Primer's target profile is $10 million to $30 million in revenue with more than $1.5 million in EBITDA (p. 24) — and belong to an owner who has no intention of transacting for another decade. Conversely, an owner can be genuinely, urgently ready to sell a business you should not buy.

The order matters. Business quality can be assessed from the outside, slowly, at low cost. Owner intent generally cannot be assessed at all until you are in a conversation. So the efficient sequence is to screen the business first, then invest conversation time only in companies that would be worth owning if the owner said yes.

Why an owner is selling is more predictive than whether

The Primer frames an ideal seller by their reason for selling:

To complete a deal, a searcher needs to identify companies with willing and motivated sellers who are selling for reasons besides deterioration in the business. Ideally, the sellers are ready to transition out of the business for retirement or personal circumstances or have other professional plans.

— Primer, p. 25

This cuts both ways, and buyers usually only apply it in one direction. An owner selling because the business is failing is a warning. But an owner with no personal reason to exit is also a warning — of a different kind. Enthusiasm without a transition event behind it tends to evaporate at the LOI, because nothing in the owner's life actually requires the deal to happen.

The Primer's guidance is to establish the underlying facts early: "Ascertaining the business owner's age, succession plan, and motivations for selling can be helpful in determining their true intentions and timeline to sell" (p. 33).

Two of those three are observable before you ever speak to anyone. Owner tenure and approximate age are matters of public record in most jurisdictions and most industries. Whether a plausible internal successor exists — a second-generation family member in the business, a long-tenured general manager, a partner — is usually discoverable too. You can walk into the first conversation already knowing whether a transition is structurally likely, and spend the conversation on the third question instead of all three.

Say your range in the first two minutes

The Primer's recommendation here is more aggressive than most buyers are comfortable with: "Past searchers recommend being up front with business owners about financial criteria and valuation ranges as early as possible" (p. 33). It supplies a model script:

I'm an investor looking for companies between $10 million and $30 million in sales and $1 million to $5 million in bottom-line earnings. I'm willing to pay four to six times EBITDA based on my research on this industry. I don't want to waste your time, so if you don't fit this profile, I can let you go.

— Primer, p. 33

The instinct is to withhold the number, on the theory that naming a range anchors the negotiation against you. The Primer's position is that the anchoring cost is small compared to the qualification benefit, because a number is the fastest way to find out whether you and the owner inhabit the same universe.

It also does something the softer version cannot: it gives the owner a graceful, immediate exit. An owner who knows within two minutes that your range is half of what they have in mind will tell you so, and you have spent two minutes. An owner who never hears a number can stay pleasantly engaged for months.

The signals that actually indicate intent

The Primer lists what a serious seller does, and it is worth quoting in full because every item is an action rather than a statement:

Indications of seller seriousness include a willingness to share sensitive business information, allowing the searcher to meet other company employees, announcing the sale process to employees, stating a price for the business, signing an exclusive Letter of Intent, and spending their own money on lawyers or other service providers in anticipation of a sale.

— Primer, p. 33

Notice the escalation. Each item costs the owner more than the one before it, and the last two cost real money and real risk. That is the point. Intent is revealed by expenditure, not by enthusiasm.

Notice also what is absent from the list: expressing interest, agreeing to a call, accepting an NDA, saying they have "thought about it," or telling you what they would need to get. None of those cost anything.

Reading a refusal correctly

The list has an awkward companion elsewhere in the Primer, and buyers who only read the seriousness list get it wrong:

Finally, many sellers are simply unwilling to provide the requested information and purposely prohibit the searcher from contacting employees, customers, and suppliers too early in the process, if at all. They want to ensure that the deal is going to close before they are willing to announce a potential ownership change.

— Primer, p. 40

An owner who will not let you talk to their sales manager in week three is usually protecting a workforce from finding out the business is for sale from a stranger — a reasonable thing to protect, and one of the reasons owners prefer a single quiet buyer to a marketed process.

The distinction that matters is whether refusals are proportionate to the stage. Declining employee access before an LOI is normal. Declining to state a price after four months is not. Declining to share financials that would be routine at the same stage of any process, while continuing to take your calls, is the specific pattern the free-valuation warning is about.

Structure the process so intent has to reveal itself

The Primer describes evaluation in three escalating stages — a first pass, a valuation and LOI stage, and comprehensive due diligence — and makes the escalation explicit: "Each subsequent stage requires a larger commitment of both time and money, and therefore an escalating commitment by both the seller and the searcher" (p. 39).

That symmetry is the mechanism. Each stage is a test the owner either passes or fails by their own behavior. The first pass, per the Primer, exists in part to "assess if the owner is genuine in wanting to sell the company" and to "determine a rough range of value" (p. 41). It generally does not include a site visit, and the searcher is still relying on the owner's own numbers.

The letter of intent is where intent becomes formal. The Primer gives it four functions, the first of which is the relevant one here: "by signing the LOI, the owner is validating the intent to sell the business" (p. 43). It is also, importantly, the moment the buyer's costs jump — legal review, capital partner conversations, and the beginning of a diligence process that runs 30 to 120 days (p. 43).

The practical rule that falls out: do not let your commitment run ahead of theirs. If you have paid for legal work and they have not stated a price, you are subsidizing an education.

Time and the willingness to settle

There is a reason this discipline erodes, and the Primer names it precisely:

Time and money are the two most valuable—and scarce—resources that a searcher has. … With approximately two years of funding available, each month that passes increases the searcher's anxiety level and willingness to "settle."

— Primer, p. 37

A buyer in month 15 with a thin pipeline will read ambiguous signals generously. This is not a character flaw; it is what scarcity does to judgment. The countermeasure is structural rather than psychological: keep enough qualified companies in front of you that no single owner's ambiguity has to be resolved optimistically. The Primer's related advice is to "continue actively sourcing new deal opportunities until the day the paperwork to acquire a company is signed" (p. 38).

A working checklist

Before a first call, know the owner's approximate tenure and age, whether an obvious internal successor exists, and whether the company sits inside your size range. If any of those is unknown, the call is a research call, not a qualification call, and should be budgeted as such.

In the first conversation, state your range. Ask directly what would have to be true for a transition to make sense, and when. Ask what they would want to happen to their employees. The answer to that last question is often the most revealing thing said in the first hour.

Before you spend money, get a stated price or a stated basis for one. The Primer treats stating a price as a seriousness indicator for good reason — it is the first thing on the list an owner cannot do casually.

Before you commit to diligence, get the LOI. Not because it binds them, but because signing it is the behavior that separates an owner who is selling from an owner who is curious.

None of this is about distrust. Owners who are genuinely unsure are the normal case, not the exception — most of them have never done this before and are working out what they want in real time. The purpose of qualifying is to make sure the months you spend are spent on the ones where the answer, eventually, is going to be yes.
