I think it depends at what time in the property cycle you bought into, as well as the area.My point is that it hardly matters how far you go out, you can't buy a property for $80K these days. (1 x single average wage.) So houses are relatively more expensive than they were 40 or 50 years ago, and to pretend otherwise simply makes you sound like the Four Yorkshiremen.
When I was looking for my first home, they were almost three times the average wage, and that wasn't in a desirable area.
Mine was in the outer suburbs of Wollongong. I could have got a nicer home for the same money if I'd ventured to Campbellown, but couldn't find anything cheaper unless I went to Cringila/Port Kembla (closer to Wollongong but very dirty, overlooking the Steel Works), which was too far for me to commute to work.
In all my time looking at property, I have never seen prices equivalent to 1 x average earnings for a Capital City property.
No, sorry, I am wrong. If you look at the outer Adelaide suburbs, I believe they have been 1 x average earnings until quite recently. I also bought in Launceston and outer Hobart very cheap ages ago, but can't recall if it was 1 x average wages.
