Don't know about 50% but some properties coming onto the market are way under what they sold for 2-3 years ago. This has been coming for some time and I have been sitting cashed up waiting for this moment for 2 years. Put in an offer at a property in Haberfield for $715,000 (3 bedroom, period home, garage, etc) which would have sold for $800,000 2 years ago and the vendor has asked if I will go to $725,000. Get out those cheque books.
