Why the client who agrees to sell still won't sell

The planning appointment is familiar: the client agrees a concentrated position should be sold, understands the math, and leaves without selling. In an Aug. 5 guest post on Kitces.com's Nerd's Eye View, Dr. Meghaan Lurtz, a professor of practice at Kansas State University, gives advisors a diagnosis for this dead end.

The formal name is the endowment effect, and it reaches past equities. Lurtz opens with soft versions—a blue coffee mug, a concert t-shirt—then moves to the family home, then to employer stock accumulated over decades. The attachment that helps clients invest in their own careers and communities, she observes, is the same attachment that makes them resist change.

The longer the ownership, the stronger the attachment. A client who has held a house or a stock for twenty years is no longer weighing an asset; they are weighing a piece of their own history.

In real estate and concentrated stock positions, this resistance is a planning hazard, not a personality quirk. It can push a retirement plan off course. And, as Lurtz writes, logic is not the cure.

Knowing the label alone is not enough. Three distinct mechanisms drive the endowment effect, and any one—or any combination—can be at work in a given client.

The first is loss aversion. Giving something up hurts about twice as much as an equivalent gain pleases, which is why sellers demand more than buyers would pay. A client weighing an offer on a house or a stock is not just evaluating the asset; they are pricing the surrender.

The second is identity. When a holding came from years of employment, it is tangled with the career that produced it. Lurtz describes the feeling as earned through "the fruits of our labor and our success as a career professional." Selling can feel like selling a version of the self.

The third is anchoring. Sellers anchor to the top of the range—the most expensive house on the street. Buyers anchor to the bottom—the cheapest in the area. Both look at the same market. Neither looks at the same number.

In practice the mechanisms blur together. A client selling the family home can carry loss aversion and identity at once, with a seller's anchor layered on top. The strongest response depends on which layer is driving the resistance, so recognition has to come before persuasion.

The post carries a warning about vocabulary as well. Tell a client their unwillingness to sell is "a result of their biases," Lurtz writes, and the likely outcome is defensiveness, not concession. The diagnosis may be accurate; used out loud, it becomes a conversation ender.

The excerpt provided stops before the post's full intervention playbook. What the advisor is left with is a diagnosis that points three ways. A loss-averse client likely needs the conversation to focus on what the sale makes possible. An identity-tied client needs to see what the sale preserves. An anchored client needs a market reference close enough to compete with their own.

For the advisor across from a long-tenured employee with a lifetime of company stock, the diagnosis changes the opening question. Instead of asking how to convince the client, ask what the client is protecting. The answer tells you whether the planning conversation is about gain, self, or price.
