This is a useful site, shows the changed in advertised prices and what price the property eventually sold for:

A quick perusal of postcodes in my area paints a very different picture than the property spruikers and sales data (of which up to 80% is being withheld and not submitted) they present would have us believe. People are rapidly readjusting asking prices, frequently after only 2-3 weeks. That suggests a market starting to panic, having little faith the status quo will be maintained.
I've seen flat out lies from agents - they run an ad showing a price they 'achieved' that was $50k higher than what the property actually sold for. You simply cant trust anything being put out by anyone that derives any income from sales. They are lying, both by omission and outright porkies.
