There's a big difference between a housing market that's exploding because of a lot of people moving to the area and one that's being largely propped up by outside purchases that don't get occupied. In a normal housing boom when a property is bought someone comes along with the money and spends money in other areas which boost the rest of the economy too. In the case of properties bought for investment/capital control dodging it all flows into a single area with less of the add on benefits.
