One of the faults of real estate analysis is the failure to distinctly define an asset bubble, so debate on the matter is kept necessarily vague. Only a couple of housing market metrics is needed to identify a bubble, and are now considered commonplace: nominal price to inflation, price to income and price to rent. On all three, Australia is both historically and internationally at or near the top.
Since the advent of the GFC, it has become commonly accepted that the global real estate booms originated from rapidly expanding bank credit or private mortgage debt. It is not merely the growth of mortgage debt (the first derivative) but the acceleration (the second derivative), also known as the change in the rate of growth. Nevertheless, the simple growth of mortgage debt provides a strong indicator for housing price growth.
