interest rates are one factor. The problem with US is the signficant oversupply in new houses let alone the foreclosed properties. Also the walk away mortgage, so why pay for something there is no value and you are not tied.
UK has an oversupply and has been impacted by the UK spain holiday home problems.
Japan has negative population growth.
But please tell us A1 and all those others that believe that the 40% is around the corner, what happens once it reaches 40%, are you and others going to buy and then what happens to prices, do they go up with inflation or what., please advise, I would be really interested as I aint very smart and english aint the first language for me
