re.com.au still using highest sale as median, page-8

The use of "median price" to describe the market is a flawed concept anyway.

I bought my house over 40 years ago but just as somewhere to live, not an investment. I had never heard the term "median" but as it was nearly new it would have been above median. Today it is a little 3br weatherboard box in a world of McMansions. A prospective purchaser would probably value the structure @ $10k which is about what it was worth back then. Without constant renovating the structure depreciates in value.

My point is that existing houses do NOT increase in value in line with increases in published medians. Any investor who counts his chickens as published medians rise is having himself on.
