We should bear in mind that most on the current and ongoing construction are properties that were sold a more than a year ago, i.e. before the credit crunch, so I wouldn't necessary assume that it's a sign of confidence for the future development. I'd be surprised if the sales today for completion in 2010 onwards are anything like as high as they were a couple of years ago, so I think it's logical to assume that when the current developments under constuction are completed there will be a delay in starting the next developments until the markets pick up again.
I suspect the majority of resales are due to people being unable to complete due to inability to secure a mortgage, and those who speculated by buying off-plan in the hope of selling their contract at or near completion for a profit.
Those who for whatever reason have to sell quickly will have to drop their prices, in the current climate there's nothing much that Polaris can do about that.
My glass remains half full however. I'm confident that in the long term we have made a sound investment.
