There can only be analysis done based on information at hand. Predicting the future movements will only ever be speculative, whether it be up or down, it is still just speculation.
Let's not forget there have been many MEDIA created "the bubble is bursting" or "the bubble is about to burst" stories.... Sometimes they have to be right... Most times they are not. They are however run at regular interval. The stories are far more cyclical than the actual property market.
