I agree rami-leb. I don't understand why either. But that doesn't change the fact that people are buying them, hence supply and demand in effect.

I heard a rumour that originally they were all put on the market at cheap prices, to stimulate sales and kick start a "flipping" chain, which in turn stimulates more interest in the properties until eventually they're sold at much a higher price than they originally could have been. Then some poor sucker is stuck with a property they want to sell on for a profit, but can't cos the price has got too high.

No idea if that's true though.
