You have completely misunderstood everything I have said if your saying this??
If you want to sell property to investors and spruik it then you talk about house prices in $ and look at charts over decades to show it "Always goes up" etc and then sell them some property.
If you want to look at housing to understand what really is going on you need to compare it to wages so as that you cant be distracted with inflation.
House prices are bought with wages and built with wages, that is why house prices always inflate with wages decade by decade deviating slightly back and forth usually influenced by interest rates.
observing that it now takes 4x more average wages to buy a house when it has never ever deviated this much before is a massive warning signal of a bubble..
nearly all other countrys that this also happened in over similar period of time have already burst.
