The agent quoting the highest figure must simply understand the market better than the others.
That is what most sellers believe when three appraisals come back forty to sixty thousand dollars apart. It feels like common sense. More market knowledge should mean a more accurate number, and the agent who arrives at the biggest figure must simply be the one who has done their homework properly.
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.
An appraisal does double duty. It functions as a valuation, but it is also, whether the agent admits it or not, a pitch for the listing itself. Two agents can inspect the same property, look at the same comparable sales, and still land on figures tens of thousands apart, because one is pricing the house and the other is pricing the chance to win the seller over. It is a distinction worth keeping in mind before the first appraisal appointment For those wanting more context before their own appraisal round check this out 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
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 Anyone weighing up how much to trust an early appraisal get the details 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 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 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.
Frequently Asked Questions
Why is there so much variation in appraisal figures for one 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?
On occasion, yes, but only when the evidence behind it earns that trust, not because it happens to be the biggest figure quoted. A high number backed by real comparable sales bears little resemblance to one offered purely to secure the business, and asking what it is actually based on is the only way to separate the two.
What is a better question to ask an agent than simply the appraisal figure?
Asking what evidence supports the number, and what the plan of the agent is if the property does not attract offers at that figure early on, tends to reveal far more than the number itself. It also tends to separate agents comfortable defending their figure from agents who were hoping the question would not come up.
Is a lower appraisal figure a sign of a weaker agent?
Not automatically. A modest, well-evidenced figure from an agent who can talk through the comparable sales in detail is frequently a better sign than a bigger number offered with no support at all. Filtering agents purely on the size of their quote is optimising for the wrong variable from the start.
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.
