One of the most common statistical measures pertaining to property investment is the good ol’ median price. Median price reflects the ‘middle’ price in a sequence of prices. It is important to understand that it is not the average price – which is calculated by adding all prices together and dividing by the number of prices involved. As a licensed Buyers Agent, we never rely on median prices...they provide a starting point only.
The median price is supposed to provide a more accurate reflection (than average prices) of property values in a particular location. However, based on 20 years ‘real world’ experience, I offer a word of warning. While the median price does provide a better indication of property price movements, it is only an indicative measure. In fact median prices really tell us more about the type of property being sold rather than value of property in a particular location.
To clarify how the median (or middle) price is calculated, let’s consider an example -
During the month of August, five houses sold in the suburb of Blacktown in Sydney:
House #1: $300,000
House #2: $350,000
House #3: $375,000
House #4: $450,000
House #5: $550,000
To establish the median price, you need to identify the price that sits in the middle of the sequence of numbers. In this case the median price is $375,000 (House #3).
To calculate the average (or mean) price, add the 5 house prices together and divide by 5 (ie the number of houses in the sequence). This results in an average value of $405,000 which is substantially different to the median price.
There are a number of potential problems with median prices including the various ways they can be calculated, not to mention the fact that prices below and above the middle price are virtually ignored – which can be very misleading!
One of the most commonly asked questions is… why do different organisations report median values that are quite different? The answer to that question lies in the methodology used to calculate medians.
If we consider three well known research-based organisations – the Australian Bureau of Statistics, Australian Property Monitors and Residex – each one uses a very different approach in their calculations which provides different results.
So which one is most accurate? It’s a matter of personal choice – personally I’ve been using Residex for many years and while I find them to be quite reliable, ‘real life’ is the only accurate measure. In other words, the value of a specific property gets down to what someone is prepared to pay for it – the market determines the price.
There are two reasons I choose to rely on Residex more so than other organisations:
- Through experience I’ve found them to come close to reality
- I like the methodology they use – based on same property sales
The moral to the story is to consider median values as a starting point to your property price research, however just like all your due-diligence, you need to look further to uncover the most up-to-date and accurate pricing information. The only way to do that is to do what we do as Buyers Agents – get out amongst it, drive the streets, ask questions and uncover the very latest (not yet reported) sales figures for comparable properties.
