A median based on a small sample of sales is statistically volatile and often unreliable for pricing individual properties. Because the median is simply the middle value of a data set, a few outlier sales—either exceptionally high or low—can disproportionately shift the figure, creating a misleading representation of the suburb’s actual value.
Low sales volume creates a sample size risk where the reported median does not reflect broader market conditions. In Melbourne’s eastern suburbs, where property types vary significantly between entry-level units and luxury estates, these skewed figures can lead vendors to miscalculate their equity.
The volatility of low sample sizes
When only a few properties sell, the median becomes hypersensitive to single transactions. For example, one high-end architecturally designed extension in a gentrifying area can pull the median upward, even if the majority of homes in that street have not seen similar appreciation.
Comparing medians to growth trends
Growth percentages can be equally misleading when based on low volume. While Knox has seen annual growth of 7.6% (Cotality, January 2026), this figure is only a reliable indicator if it is supported by a consistent volume of comparable sales across the region.
Pricing unique features
Properties with unique features are inherently difficult to price precisely. In suburbs with low sales activity, these homes further distort the median, which is why auctions are often favoured for properties with broad appeal and unique attributes to let the market determine the final price.
The appraisal spread
In low-volume suburbs, the gap between a conservative and an aggressive appraisal widens. Without a dense data set of recent comparable sales to narrow the range, there is a higher risk of either underpricing the home or setting an expectation that the current buyer pool cannot meet.

Frequently asked questions
How do I know if my suburb’s median price is reliable?
Check the total number of sales used to calculate the median for that period. If the sample size is small, the figure is likely volatile. Reliable medians require a consistent volume of sales that reflect a variety of property conditions and sizes within the suburb.
Should I use the median price to set my asking price?
No. The median is a broad indicator, not a valuation tool. Use specific comparable sales of similar homes sold within the last three months. This provides a more accurate reflection of what buyers are actually paying for your specific property type and location.
Why are some eastern suburbs showing higher growth than others?
Growth is often driven by specific catalysts. For instance, gentrification signals such as specialty retail and heritage renovations can lead to appreciation of 8–15% over 2–3 years. Other areas may benefit from first-home buyer incentives or new infrastructure projects.
Is an auction better in a suburb with very few sales?
Yes, if the property has broad appeal and the suburb maintains a clearance rate above 65%. Auctions create a transparent, unconditional sale and allow competing bidders to establish the market value when recent comparable sales data is sparse or unreliable.
Questions to ask your agent
- How many comparable sales in the last 90 days have actually supported this price guide?
- If we use an auction, what is the current clearance rate for similar property types in this specific pocket?
- How have recent gentrification signals or infrastructure upgrades in the area affected the value of similar homes?
