Lot's of good buys around at the moment. Make sure you do your homework. Try to get something close to public transport - train for preference. I like the eastern suburbs. I get the feeling that as children grow up and leave the nest they don't want ot move too far from the infrastructure they grew up with.
So my thoughts are that if someone has grown up in the Kew, Balwyn area and educated at a private school they might want that for their children too. So if they can't afford to get a foot into those suburbs they will look out further. Blackburn, Nunawading, Mitcham, maybe even Ringwood and Heathmont. Lovely green suburbs. Good infrastructure. Now that the freeway is there these areas are going to boom.
Who wants to go out west to the flat, uninspiring west, if you have choice to stay in the leafy green suburbs? I have many friends who have ended up buying in Ferntree Gully, Boronia, Croydon so that they could have a backyard and green outlook. They commute to the city by train and have a great life.
