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.
What looks cosmetic to one buyer looks like a discount to another.
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.
The Role of Market Momentum in Pricing Opinions
Experience in the current market - not just the historical market - changes how an agent reads the range.
Agents also differ in how much they lead the market versus reflect it. Some price to where they believe the market is heading. Others anchor tightly to where it has been. Both approaches have merit. They produce different numbers.
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.
What to Do With Two Different Numbers
Two different appraisal figures give you more information than one. The gap between them tells you something about where the evidence is concentrated and where it becomes a matter of interpretation.
An agent who delivers a figure without a clear methodology is offering optimism, not analysis.
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?
Higher is not always better. Achievable is better.
Is a large gap between appraisals a warning sign?
Some variation is expected. Two well-reasoned appraisals on the same property can legitimately differ by five to ten percent and both remain defensible. A gap larger than that is worth questioning - it suggests agents are working from meaningfully different comparable sets, different condition assessments, or different market confidence levels. Ask both agents to explain their reasoning before drawing conclusions.
Why do some sellers choose the agent with the highest appraisal?
Some sellers do choose the highest figure, particularly when the gap feels significant. This is understandable but carries risk. An agent who has overestimated to secure the listing may then manage a price reduction process - which is a worse experience than a well-managed campaign at a realistic price. Select the agent whose reasoning is clearest, not whose number is largest.
Is it reasonable to question an agents appraisal methodology?
Good agents welcome the questions. It is how they demonstrate that the number is grounded.
Working through what each appraisal is actually saying - rather than just comparing the figures - is where the real value of the process sits. local market understanding is the practical resource for sellers navigating this question in the local market.
