Housing policies should be revamped to avoid duplication and confusion, experts say, adding that the Government has introduced more than enough schemes to bolster the troubled property market. And they have called on Tung Chee-hwa to make clear the roles of housing bodies in his second Policy Address in October. 'The Housing Authority is over-enthusiastic in convincing public housing tenants to buy homes by introducing different housing schemes,' said Hong Kong People's Council on Public Housing Policy spokesman Virginia Ip Chiu-ping. 'The moves are to achieve a 70 per cent home ownership rate by 2007 as pledged by Mr Tung in his policy speech last year,' she said. 'These moves have violated the original role of the Housing Authority to build cheap rental homes for those in need.' About 150,000 people are waiting for public housing, with an average wait of 6.5 years. The three subsidised schemes for public housing tenants are run by the Housing Authority. The Home Starter Loan Scheme, also run by the Housing Society, was extended to non-principal public housing tenants last Tuesday. Shih Wing-ching, managing director of Centaline Property Agency, said: 'It is wrong for the housing bodies to build flats for sale when there are so many people urgently needing a cheap rental shelter. 'All housing schemes should be scrapped,' he said. But Housing Authority's Home Ownership Committee member Michael Choi Ngai-min, the managing director of Hong Kong Property, said redefining roles would jeopardise the housing bodies' finances.
