A pilot scheme for a new type of subsidised housing, announced in Chief Executive Leung Chun-ying's January policy address, will fall at least two months behind schedule, with details of resale conditions yet to be finalised. The scheme would allow public housing tenants buy flats even cheaper than those offered under the Home Ownership Scheme, which sell for 70 per cent of market value, in an attempt to shorten the waiting list for public rental flats. Officials had hinted at discounts of 50 per cent. Housing minister Professor Anthony Cheung Bing-leung set the end of this month as the target date for the Housing Authority to agree the details, including prices, eligibility and conditions for the resale of flats. But members of the authority's subsidised housing committee, which decides the rules for such schemes, said it had yet to receive a concrete proposal from the Housing Department for its consideration. The pilot was not on the agenda for a behind-closed-doors meeting of the committee yesterday and it will not meet again until May. Speaking after the meeting, committee chairman Stanley Wong Yuen-fai said the authority still hoped to launch the pilot in the first half of this year. "We don't have a timetable as to when to come up with the details. We would rather take more time to examine the policy in detail than rushing to launch the pilot scheme," he said. Wong said the scheme had been discussed by the authority's strategic planning committee, but members had mixed views on the contentious question of how to treat owners who decide to sell their flat. Some favour resale rules that mirror those for HOS tenants, who cannot sell for two years, then are restricted in whom they can sell to for the following three years. They must then pay the authority a sum based on the discount they received when they bought the flat if they want to sell or lease it. Others want stricter conditions on whom the buyers can sell to, with some insisting the flats should only be resold to public housing tenants. A Housing Department official told Kwai Tsing District Council last week that a HOS project with 500 flats in Tai Wo Hau would be turned over to another type of subsidised housing, fuelling speculation it would fall under the pilot. But Wong said the authority had not yet discussed locations for the pilot.
