The agent who says your house is worth the most clearly knows the market best.
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 Appraisal Gap Sellers Do not Question
A seller who collects three appraisals for the same property is not usually looking at three versions of the same number with small variations. The spread is often large enough that at least one agent has to be substantially wrong. Sellers rarely stop to ask which one that might be. Instead, the natural instinct is to trust the highest figure, because it is the one that matches what the seller was already hoping to hear.
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 those wanting more context before their own appraisal round find out more can help fill in the gaps early on. Either way, the pattern tends to hold regardless of which agent a seller speaks to first.
Why the Biggest Figure Rarely Reflects True Value
Quoting a high number is not evidence of deeper market insight. More often it reflects a readiness to say whatever secures the mandate. That does not require deliberate dishonesty from the agent. Many genuinely believe the optimistic figure, at least until the campaign gets underway and the market tells a different story. Whatever the intent behind it, the seller still ends up appointing an agent on the strength of a number that was never really about the market.
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 relevant information is worth a look before appointing anyone. The details vary by campaign, but the underlying lesson tends to repeat.
What a Genuinely Defensible Appraisal Looks Like
The appraisals worth trusting are rarely the ones stated with the most enthusiasm. They are the ones supported by specific comparable sales, recent settlement data, and an honest account of what buyers have actually paid for similar properties nearby in recent months. An agent who can walk through the evidence behind their number is doing something fundamentally different to one who simply asserts a figure with confidence. Confidence of delivery and accuracy of number are not the same thing, and sellers who cannot tell the difference tend to select for the wrong one.
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 Sellers Should Be Evaluating Instead
The right question is rarely which agent believes the property is worth the most. It is closer to which agent has a genuine strategy for reaching real market value, and which one is willing to have an honest conversation if the campaign does not move at the quoted figure straight away. How an agent has previously handled a mid-campaign price adjustment tends to say far more than any number offered at a first meeting ever could.
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.
Is the highest appraisal ever the right one to trust?
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 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.
