Whichever agent names the biggest number is obviously the one who has done the most homework.
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
When a seller gathers three appraisals for the same property, the results are rarely a tight cluster around one figure. The spread is frequently wide enough that at least one number cannot be close to right. Sellers seldom stop to consider which. The default is to believe the highest one, largely because it lines up with what the seller wanted to hear in the first place.
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 those wanting more context before their own appraisal round more information offers useful local context. Whichever agent walks through the door first, this dynamic is usually already in play.
Why a High Appraisal Is not the Same as an 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. The seller ends up in the same position regardless: an agent chosen on a figure that was never really about the genuine value of the property.
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. Recent examples from local campaigns make this easy to see Anyone weighing up how much to trust an early appraisal see more here helps explain what to watch for early. The details vary by campaign, but the underlying lesson tends to repeat.
What a Genuinely Defensible Appraisal 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.
Confidence is cheap. Comparable sales data is not.
The Questions Sellers Should Be Asking Instead
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 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.
What Sellers Usually Want to Know
Why does the same property get such different appraisal figures from different agents?
Every appraisal mixes genuine market assessment with an incentive to secure the listing, and agents weigh those two elements differently. Much of the spread between quotes comes down to that incentive rather than the property itself. An agent under pressure to bring in new business has every reason to lean optimistic, regardless of what the comparable sales actually show.
Can the biggest appraisal figure ever actually be the correct one?
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.
