I'm not sure on Ballarat, but in Melbourne there's a general concensus that prices are falling (but not crashing).
The REIV figures for the first quarter of this year showed a fall of 6% in house prices, and 4% off units over the last three months. The ABS figures show a slower decline of around 2.5%.
Annualised, that's between a 10% and 25% fall, and if it continues for a couple of years is definitely in crash territory.
As with all these things, it's a case of where you draw the line.
I've said it before, but falling house prices are often a precursor to a recession. If this is a major correction, soon to be followed by a general economic downturn, then hold off for a few years. If it's not then buying in sooner might make more sense.
Of course we won't know which it is for a few months...
