The agent quoting the highest figure must simply understand the market better than the others.
Most sellers reach this conclusion the moment three appraisals arrive forty to sixty thousand dollars apart. On the surface it tracks. A sharper read on the market should produce a bigger, more defensible number, so the agent with the highest figure must be the one who understands the property best.
The Appraisal Variation Sellers Take at Face Value
Three appraisals on the same property rarely land as close variations on one number. The gap between them is often wide enough that one figure has to be significantly off the mark. Few sellers pause to work out which one that is. The instinct instead runs toward the largest figure, since it happens to match what the seller was hoping to hear from the start.
An appraisal is not just a valuation. It is also, whether stated or not, a pitch for the listing itself. Two agents can walk through the same property, see the same comparable sales data, and still arrive at figures tens of thousands of dollars apart, because one of them is pricing the house and the other is pricing the opportunity to win the trust of the seller. Sellers who grasp this early tend to interview agents very differently For sellers still deciding who to trust with the campaign read here offers useful local context. Either way, the pattern tends to hold regardless of which agent a seller speaks to first.
Why the Largest Quote Is Often the Least Reliable
A high quoted figure is not automatically a sign of stronger market knowledge. Just as often it signals a willingness to tell the seller what they want to hear, purely to win the listing. That is not always conscious dishonesty either. Plenty of agents believe their own optimistic number right up until the campaign runs and the market disagrees with them. The seller ends up in the same position regardless: an agent chosen on a figure that was never really about the genuine value of the property.
The uncomfortable part of this is that the seller rarely finds out until well into the campaign, once the property has already been on the market for several weeks without the interest the appraisal implied it should attract. Recent examples from local campaigns make this easy to see Anyone weighing up how much to trust an early appraisal details here puts some useful structure around this decision. The details vary by campaign, but the underlying lesson tends to repeat.
The Difference Between a Confident Number and an Accurate One
The appraisals actually worth listening to are rarely the most confidently delivered ones. They are the ones backed by real comparable sales, recent settlement figures, and a straightforward account of what nearby buyers have genuinely paid in recent months. An agent who can walk a seller through that evidence is doing something entirely different from one who just states a number with certainty. Confidence and accuracy are not the same thing, and sellers who conflate them tend to pick the wrong agent for the wrong reason.
There is a simple test for this. An agent with a genuinely defensible number can usually name the specific sales they are comparing against, within a reasonable timeframe and a comparable location. An agent relying mainly on optimism tends to speak in generalities about the market being strong, without pointing to anything specific that supports the figure they have just quoted.
Confidence is cheap. Comparable sales data is not.
The Questions Sellers Should Be Asking Instead
The question worth asking is rarely who thinks the property is worth the most. It is closer to: who has a defensible strategy for reaching genuine market value, and who is prepared to have an honest conversation if the campaign does not move at the quoted figure straight away. The track record of an agent on this specific point, how they have handled properties that needed a price adjustment mid-campaign, tends to reveal far more than any single number offered at the first meeting.
This is also where a seller can learn the most simply by asking directly. An agent willing to discuss what happens if the first few weeks do not go to plan is behaving very differently to one who has only ever talked about the upside.
What Sellers Usually Want to Know
Why does the same property get such different appraisal figures from different agents?
Every appraisal mixes genuine market assessment with an incentive to secure the listing, and agents weigh those two elements differently. Much of the spread between quotes comes down to that incentive rather than the property itself. An agent under pressure to bring in new business has every reason to lean optimistic, regardless of what the comparable sales actually show.
Is the highest appraisal ever the right one to trust?
Sometimes, but the trust should come from the evidence supporting it, not from its size. A high figure grounded in genuine comparable sales is an entirely different thing to one pitched purely to win the listing, and the only reliable way to tell them apart is to ask what the number is actually based on.
Instead of asking for a number, what should sellers actually ask?
Asking what evidence sits behind the figure, and what the agent plans to do if the property does not attract offers at that price early on, tends to reveal far more than the number ever could. It also tends to separate the agents willing to defend their number from the ones hoping nobody asks.
Should sellers be wary of an agent who quotes a lower number?
Not necessarily. A lower, well-supported figure from an agent who can walk through the comparable sales behind it is often a stronger signal than a higher figure with no evidence attached. Sellers who filter agents purely on the size of the number they quote are optimising for the wrong variable entirely.
An appraisal functions less as a measurement of the house and more as an opening bid for the right to list it, and sellers who see this early tend to make a very different call to those who simply chase the biggest number. Throughout the Gawler District and the northern Adelaide corridor, where appraisal spreads can be just as wide as anywhere else in Adelaide, this distinction carries even more weight, given how quickly a mispriced campaign can stall in a market where comparable listings tend to appear close together.
