"Apparantly the future price growth of every single property in Australia is directly linked to national wages growth and/or national median price growth?"
There is a strong correlation, so it is linked. Doesn't mean a change in one has a direct or immediate impact on the other. Put another way, if wage growth was -10%/annum for the next 10 years, clearly property, on average, would be expected come down with it.
Market value is dictated by what someone can afford (is willing to). You're suggesting we ignore the capacity of the buyer to pay. There is a reason that when assessing affordability the ratio median wage : median house price is used, because to compare absolute price of housing in Australia, to say Africa, is a waste of time. Instead we must consider what the typical income of Africans is. Apparently, you think the income side can be ignored, or at least consider its impact negligible.
How would you go about comparing affordability of housing between a first world, and third world country? Doesn't need to be perfect, but what metrics would you use?
"Successfull property investment is more and more about cherry picking: thats exactly what smart investors do. "
Same can be said of stock market, nothing new here.
It's fine that you are able to pick properties that turn a profit in an uncertain market, but the heady days of basically everyone turning a significant profit look to have come to an end. Buyers need to be cautious now, and carefully manage risk - because turning a profit is far from a certainty in this market.
