Whichever agent names the biggest number is obviously the one who has done the most homework.
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 Variation Sellers Take at Face Value
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 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 those wanting more context before their own appraisal round learn about this puts some of this in local context. Whichever agent walks through the door first, this dynamic is usually already in play.
Why the Biggest Figure Rarely Reflects True Value
An agent quoting a high figure is not necessarily demonstrating superior market knowledge. Often they are demonstrating a willingness to tell the seller what they want to hear in order to win the mandate. This is not always deliberate deception. Some agents genuinely believe their optimistic number, at least until the campaign runs and the market fails to agree with them. Either way, the seller ends up choosing an agent based on a number that was never really about the market at all.
The hard part is that this rarely becomes clear until well into the campaign, once several weeks have passed without the interest that the initial appraisal had implied would show up. A closer look at how this plays out shows the pattern clearly Sellers wanting to understand this dynamic in more depth continue reading is worth a look before appointing anyone. 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 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 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 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.
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?
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.
What is a better question to ask an agent than simply the appraisal figure?
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.
Rather than a true measurement of the house, an appraisal is really an opening bid for the listing itself, and sellers who recognise this early tend to choose very differently to those chasing the highest figure. Across the Gawler District and the northern Adelaide corridor, where the spread between agent appraisals can be just as wide as elsewhere in Adelaide, this distinction matters more rather than less, given how fast a mispriced campaign can lose momentum where comparable listings surface close together.
