Changes in average prices are frequently used by commentators to draw conclusions about the property market. Our recent post on Fitzroy’s true capital growth gave some insight into why statistics like averages and medians are not sufficient to make judgements on property value in a given suburb.
To find true growth in value, many factors including property size, location and renovation levels need to be accounted for. This can be done by observing resales of the same property over time, given no structural changes have occurred between sales. When we compare the annual average price changes (reported) and our own index based on resales only, we start to see that capital gains are mostly exaggerated using averages alone.
