The last large downtrend in Real Estate in Queensland, especially the SE corner ended in 1996. Some properties hadn't moved in the 5 years before that. Quite a few properties built new in those years, were getting passed in at auctions. ie. 3 - 4 year old residential property, getting no bids, at just over half the cost to build it. That was the worst property slump in my lifetime. (77 years)
I don't think the trend is regular enough, to accurately predict....Marum.
