Sydney Suburbs Statistics

Hi,

I have found that the 10 year average growth rates for each Sydney suburb to vary depending on the source.

e.g. Petersham units are at 11.3% 10 year average growth rate in the 2008 Domain Property Guide/Aus Property Investor, whereas it is -0.9% in the Your Investment Property Magazine. In Waterloo units it is 8.1% compared to -0.7%.

I have also found that the median prices and growth rates for units can also be skewed when townhouses are categorised as units and inflating the price and difference in the growth rates from year to year. For houses, it is more accurate.

In my area of Fairfield, around two years ago there were many new blocks of apartments, making the median price $250,000 and the year after the median price was $192,000 bring the median price back to the average of the units in the area. This made the statistic -23% for the year and pulled the long term average growth rate down from around 9% to 6.6%.

So generally I use it only as a guide.

Does anybody have the median or average price for houses/units of some or all of the Sydney suburbs of 10 or more years ago, or know of any websites that have this information. From that, the annualised increase could be calculated more accurately.

My aim is to find the suburbs which have high long term growth rates for 10+ years timeframe, and preferably for inner city suburbs and at around the median Sydney house/unit prices. The confusing thing is that different sources can show very different statistics.

Also, does anyone have the growth rates for each suburb for commercial property?

Many thanks
