Milesg, I agree mate. Unless you find something very "unique" I would not be jumping in either mate. I am just pointing out it isn't quite the doom and gloom some are saying it is.
BTW if rents continue to rise and in WA they will for a while then the "good" old days of finding properties in depressed areas that are self funding might come back. Now in that case it could be well worth it.
Good luck BTW mate the Western Supurbs are a fantastic place to live.
