Developers have pledged to release the price lists of new projects to be launched after coming under fire for not being sufficiently transparent in their internal sales practices. New World Development, Chinese Estates Holding, Chinachem Group and HKR International said they would follow guidelines issued by the Real Estate Developers Association (Reda) by releasing price lists for units they put on the market. But Cheung Kong (Holdings) was unavailable for comment and Sun Hung Kai Properties said it would follow the guidelines. Those developers who agreed to release price lists said the number of units included would be subject to their sales strategy for each project. None of them said it would issue a price list that would include all units to be put on internal sale, which could be up to 90 per cent of a project's units. Estate agents said releasing the price list of a new project's internal sales under the guidelines was insufficient to boost transparency. Developers still had the option of picking and choosing what information they wished to release. Under Reda's guidelines announced last month, a price list and a list of units offered for private sale should be made available to prospective purchasers, but it does not specify the minimum number of units or the release time of a price list. 'Even if a price list is provided, it usually contains less than 30 units and is released to flat-seekers on the same day they have to make a decision. Most units listed are often sold or reserved by bulk purchasers already and flat-seekers would need to buy unlisted units by negotiation,' an agent said. Chan Chi-ming, general manager of Hong Kong Resort Company, a subsidiary of HKR International, said: 'It is very difficult to give potential buyers a full price list for some projects. For our recent housing project, Le Bleu in Tung Chung, we almost raised our asking price for every house that was sold. It is not practical to give flat seekers a full price list as prices are subject to change any time.' But Mr Chan said his firm would provide a price list on a flexible basis to comply with the new guidelines. Akan Wong Ho-yin, a sales and marketing manager of New World Development, said a price list would be available to buyers when the firm's latest 310-unit project in Tuen Mun was released for sale soon. 'Buyers will have a price list for each batch of units we put on the market, but we can't confirm the number of units to be released each time.' Peter Or Oi-bon, sales manager of Chinese Estates Holdings, said the firm would release price lists for its new Wan Chai project.
