As Chief Executive Leung Chun-ying's government gets down to work, Hong Kong 's property scene is braced for change. Observers of emerging housing policies would have noted that the high-end and mass market are apparently receiving differing treatment. Arguably the most high-profile early housing policy announcements are about subsidised Home Ownership Scheme (HOS) flats. Qualified buyers have an income ceiling, but they are also potential buyers of private properties. Turning HOS flats into an active market is something that could impact on the medium-tier homes market. On the other hand, the government has rejected reports that it would increase the plot ratio of properties in popular urban locations, a move that would increase supply of high-end homes and put pressure on prices of well-located properties. Now it looks like supply will remain tight, and the policy of increasing supply will be a long-term rather than short-term target.
