The agent quoting the highest figure must simply understand the market better than the others.
This is the assumption most sellers land on once three appraisals come back forty to sixty thousand dollars apart. It seems like straightforward logic. Greater market knowledge should translate into a more accurate figure, so the agent quoting the highest number must simply be the one who has researched the property most thoroughly.
The Gap Between Appraisals That Nobody Questions
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. It is a distinction worth keeping in mind before the first appraisal appointment For sellers wanting a clearer picture of how this plays out locally this article 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.
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. Anyone who has watched a few of these campaigns unfold can see why Those wanting a fuller picture of how agent selection actually works see more 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. Delivery and correctness are two separate qualities entirely, and sellers who conflate them tend to pick the wrong agent for the wrong reason.
There is an easy way to test this. An agent whose number genuinely holds up can usually name the specific sales it is based on, within a sensible timeframe and a genuinely comparable location. An agent leaning mostly on optimism tends to talk in vague terms about a strong market, without ever pointing to anything concrete behind the figure 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 where a direct question tends to teach a seller the most. An agent willing to talk through what happens if the opening weeks do not go to plan is behaving very differently to one who has only ever discussed the upside.
Frequently Asked Questions
What explains the gap between appraisals on an identical property?
Appraisals combine genuine market judgement with an incentive to win the listing, and different agents weigh those two things differently. The spread between quotes often reflects that incentive as much as it reflects the property itself. An agent under pressure to secure new business has a reason to lean optimistic that has nothing to do with the comparable sales in the area.
Is it ever safe to just go with the highest number quoted?
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.
What questions reveal more than simply asking what the house is worth?
Asking what the number is actually based on, and how the agent intends to respond if the property does not draw offers at that figure early in the campaign, usually reveals more than the appraisal itself. It also tends to expose which agents are comfortable defending their figure and which were quietly hoping the question would not surface.
Does the size of the appraisal reflect the quality of the agent?
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.
