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 Gap Sellers Do not Question
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 anyone weighing up their options before signing anything this article is a reasonable place to start. 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.
What makes this uncomfortable is that sellers rarely find out until the campaign is well underway, once the property has sat on the market for weeks without the level of interest the original appraisal implied it should get. Recent examples from local campaigns make this easy to see Sellers wanting to understand this dynamic in more depth full article here puts some useful structure around this decision. Either way, this is the kind of thing worth knowing before the first inspection, not after.
What Separates a Reliable Appraisal From an Optimistic 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 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.
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.
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.
Is a lower appraisal figure a sign of a weaker agent?
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.
