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.
Why the Appraisal Spread Rarely Gets Challenged
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.
Beyond being a valuation, an appraisal always carries a second function: it is a pitch for the mandate, whether or not the agent frames it that way. Two agents can walk through an identical property, review identical comparable sales data, and still arrive at wildly different figures, because one is genuinely pricing the house while the other is pricing their own chance of winning the listing. Sellers who grasp this early tend to interview agents very differently For anyone weighing up their options before signing anything read this can help fill in the gaps early on. The specifics change from agent to agent, but the underlying pattern rarely does.
Why the Highest Number Is not the Most Accurate One
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. Either way, the outcome is the same: an agent chosen on a figure that was never really about the genuine value of the property.
What makes this uncomfortable is that sellers rarely find out until the campaign is well underway, once the property has sat on the market for weeks without the level of interest the original appraisal implied it should get. Anyone who has watched a few of these campaigns unfold can see why Sellers still working through what to look for in an agent this article gives a clearer sense of what actually matters here. It rarely changes the fundamentals, but it can save a seller from finding out the hard way.
What a Confident Appraisal Actually Looks Like
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.
The property is not the problem here. The appraisal process is.
What Matters More Than the Number Itself
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 the point where simply asking reveals the most. An agent prepared to discuss what happens if the first few weeks underperform is doing something very different to one who has only ever talked about the best-case outcome.
Common Questions About Agent Appraisals
Why do agents give different appraisals for the same house?
An appraisal blends real market judgement with the incentive to win the mandate, and different agents balance those two things differently. The variation between quotes often says as much about that incentive as it does about the property. An agent chasing new business has a reason to lean optimistic that has nothing to do with the actual comparable sales.
Does the largest appraisal figure ever turn out to be accurate?
Occasionally, but it should be trusted because of the evidence behind it, not because it is the largest number offered. A high figure backed by genuine comparable sales is a different thing entirely to a high figure offered simply to win the business, and the only 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 really. A lower figure backed by an agent who can clearly walk through the comparable sales is often a far stronger signal than a higher one with nothing behind it. Sellers who choose agents based purely on the size of the quoted figure are optimising for the wrong thing entirely.
An appraisal is not a valuation of the house. It is an opening bid for the listing itself, and sellers who understand this early tend to make a very different decision to those who simply follow the biggest number to the door. Across the Gawler District and the northern Adelaide corridor, where appraisal spreads between agents can be just as wide as anywhere else in Adelaide, this distinction tends to matter more, not less, given how quickly a mispriced campaign can lose momentum in a market where comparable listings appear close together.
