Buyers under DPS has to pay more in total, so those with cash will not opt for this. We can conclude many of these DPS buyers are shallow-pocket flippers. What makes it worse is the unexpected credit crunch. Besides, flippers are normally people with a risky-income profile like bankers, remisers, property agents ... who make a lot of money in the 2007-boom and became too optimistic about the property market. These people will be faced with sudden loss of income and will find it very hard to get a bank loan. DPS buyers cannot just walk away from the deals and think their maximum loss is the 10-20% downpayment. Developers can resell at any lower prices and the defaulting buyers will have to pay the difference plus all legal fees. So these shallow-pocket flippers will have to sell their units at whatever prices the market will pay. I see a property price crash coming from middle 2009
