The agent who says your house is worth the most clearly knows the market best.
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. It is a distinction worth keeping in mind before the first appraisal appointment For anyone comparing agents before committing to one read here 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
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.
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. A closer look at how this plays out shows the pattern clearly Anyone weighing up how much to trust an early appraisal more 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 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.
What Actually Deserves Attention From a Seller 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 direct question tends to teach a seller the most. An agent willing to talk through what happens if the opening weeks do not go to plan is behaving very differently to one who has only ever discussed the upside.
What Sellers Usually Want to Know
What explains the gap between appraisals on an identical property?
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.
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.
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.
Does a lower appraisal mean a worse 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 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.
