House Price Could Fall Another 40% From Here !

At least acording to the article I have just read:
(www.moneyweek.com/investments/property/h...).

I understand why there such confusion to the future of house prices, but what I dont understand is why there is so much confusion of where on the 'curve' we are right now?

Every day I see a report/article stating evidence that 'House prices on on the rise again and increaseing by 1% a month' (or whatever) then the next day 'Worse crash since the 1930 great depression as prices continue to fall 3% a month...blah blah' - Now I'm I the only one who finds this confusing or is that the intention?

I can only guess that they are generating their numbers based on different data - if not then they must simply be lying to us! - Fine if they are Estates Agents or Morgage Lenders I can filter them out - but it doesn't appear to be that simple - One Estate Agent says down the other up, One government body say all fine keep buying, the next says batten down the windows and stock up on tinned food because the storm will get worse before it gets better!!

I guess what Im saying is who really knows what is going on?  And where do they write their blog ?  Any guidence welcome !

I'm interested in this - I'm going to be moving to the area soon so will be following the market.
