Actually, I have plenty of property and am developing more, just not in main centres, but where there is real value and rental yield to support the prices in those areas.
In regards to distances from main cities, we are talking about locations similar to Sutherland and the Northern beaches. What would you be paying for similar houses in these locations $1-2M+?
Matt I as a whole agree with your posts but just because a property or area doesn't have a high rental yield doesn't mean it isn't real value. If you get a property in a top spot at the bottom of the market or before the area is revalued then your capital gains are going to represent pretty good value for money.
There will always be demand for inner city or beach suburbs near major cities but there might not be for towns with large mining operations.
Having said all this the soul IP I own is in Whyalla. Next place I will be looking is Brisbane, hope the prices stay down for a little while yet though!
