What is a median property price?
A median is the middle value after transaction prices are arranged from the lowest to the highest. If there is an odd number of transactions, the transaction in the middle becomes the median. If there is an even number, the median falls between the two middle values.
This is different from a simple average. An average can move substantially when a dataset contains one or two unusually high-value transactions. A median is generally less sensitive to those extreme values.
For property analysis, this makes the median useful as a market benchmark, particularly when transactions within the same location vary substantially in size, condition and exact property characteristics.
Median price is not a property valuation
A market median describes a group of transactions. It does not determine the exact market value of one individual property.
Two houses within the same neighbourhood can transact at different prices because of land area, floor area, renovation, tenure, orientation, condition, exact street and other characteristics.
A median is therefore best used as a starting benchmark. More detailed comparison is required before making a purchase, sale or financing decision.
How buyers can use median transaction data
A buyer can compare an asking price with the historical transaction range and median for a relevant property group. A large difference does not automatically mean that the asking price is unreasonable, but it identifies an area that deserves further investigation.
The comparison becomes more useful when the selected transactions represent a similar property type and location instead of combining unrelated properties into one dataset.
PropMedian is designed around this principle: start with actual transaction-based benchmarks and progressively narrow the market being compared.
