UT, really I wouldn't get too upset about the crash if I were you.
The type of dwellings that you dabble in may actually be immune from the fallout. If anything you may do alright.
I mean the countless landlords turn ex-landlords in Adelaide will soon need cheap rental accomodation after having to sell the family home as they can't offload their empty investment properties (continuously falling in price) in the glut (while owing the banks neck high in debt).
