Why Appraisals Are Not Purely Objective
Two agents. Same property. Two different numbers. That is not a system failure - it is how appraisals work.
Every appraisal draws on comparable sales, current market conditions, and the physical state of the property. But the agent interpreting that information is making a series of judgement calls throughout. Two agents making slightly different calls at each step will land at different numbers.
A well-reasoned appraisal can sit at the upper end of that range. Another well-reasoned appraisal can sit lower. Both can be defensible. The question worth asking is not which number is right - it is what reasoning produced each one.
How Comparable Selection Drives the Gap
Selecting comparables is a deliberate act. Not all agents make the same selection.
Recency, proximity, condition similarity, land attributes - agents assign different weight to each variable. Small differences in that weighting compound across three or four comparables. The result is a gap at the end.
Local market knowledge shapes comparable selection significantly. An agent who has been active in the Gawler area consistently will know which streets generate stronger buyer interest, which pockets outperform the broader suburb, and which results reflected unusual circumstances that should be discounted. That knowledge filters which comparables are treated as signal and which are treated as noise.
Why Property Condition Is Assessed Subjectively
Condition assessment is not a mechanical process. Agents apply experience-based judgements about how buyers in that market respond to specific features, deficiencies, and presentation qualities. That experience is not identical across agents.
Neither is guessing. Both are drawing on observed buyer behaviour. The behaviour they have each observed may genuinely differ.
Condition is assessed. It is not guessed.
Presentation affects the assessment in ways that are real but imprecise. A well-presented home in good condition is easier to appraise with confidence. A tired home in a mixed condition state gives agents more variables to interpret - and more room to diverge.
That is normal. It has always been normal.
How Current Conditions Influence Each Agents View
Market confidence is not a fixed variable. Agents who are actively working a market develop a feel for whether it is accelerating, stabilising, or softening - and that feel influences where they position an appraisal.
Timing compounds this. An appraisal done in a rising market will typically sit higher than one done six weeks earlier in a more uncertain environment. If two agents appraised your property at different moments, even a short time apart, market movement alone could produce different figures.
None of this makes one agent better than the other. It makes them human interpreters of a living market - one that does not hold still long enough to be read identically by two different people at the same moment.
How to Interpret Conflicting Appraisals
If the figures are close, the range the market is likely to accept is probably narrow. If they diverge meaningfully, the pricing decision carries more strategic weight - and more consequence either way.
Ask each agent to walk you through their reasoning. Which comparables did they use. How did they weight them. What did they observe during the inspection that influenced the number. An agent who can answer those questions clearly is giving you an appraisal you can interrogate - which is the only kind worth building a campaign around.
The most useful thing two appraisals can do is help you understand the range. Where does the evidence support confidence. Where does it start to rely on assumptions. Knowing that boundary is what allows you to price with intention rather than hope.
Common Questions About Property Appraisal Differences
Is the highest appraisal the most accurate one?
An appraisal that cannot be defended by comparable evidence is a liability, not an asset.
How much variation between appraisals is normal?
Large gaps are not automatically a problem. They are a signal to ask more questions.
Does the agent who appraises highest always get the listing?
The number is easy to inflate. The methodology is harder to fake.
How do I find out if an appraisal is well-reasoned?
Completely reasonable. A professional agent expects to be asked. The questions worth asking are: which comparables did you use, how recently did they sell, what adjustments did you make and why, and what buyer profile are you expecting to target this campaign at. Clear answers to those questions are more valuable than the figure itself.
Sellers in the Gawler and surrounding suburbs market who engage with this process - rather than just receiving a number and reacting to it - consistently make better pricing decisions. market positioning is where local appraisal expertise and current market knowledge come together.
