Sino Group is believed to be interested in selling its luxury property Royal Cliff in Repulse Bay as part of its plan to off-load investment properties to increase cash flow. Royal Cliff, at 58 Repulse Bay Road, comprises 53 apartments and duplexes ranging from 2,800 to 4,320 square feet which have been kept as rental properties since the project was completed in 1994. Market sources said the group was considering releasing the units for sale to boost cash flow. A Sino spokesman would not confirm plans to sell Royal Cliff units, but said the company was now selling some of its rental properties in Argyle Street and Sai Kung. Estate agents said should they go on the market, the Royal Cliff units, overlooking the beach and sea, would be much sought after by end-users. Some predicted asking prices could exceed $10,000 per sq ft. Agents said rents were as high as $55 per sq ft a month at the peak, but had fallen to about $35 per sq ft. Jacob Wong, senior manager of Treasure Land Property Consultants' residential department, said Royal Cliff would appeal to end-users because of the limited supply of similar properties in the area. The large unit size and lump sum involved would restrict the number of buyers to those who could afford to spend that much on luxury flats amid the market downturn, he said. Centaline Property Agency supervisor for the Peak and Island South section, Steve Lee, said the market was dominated by end-users, so if the units sold were vacant, the response would be better. Royal Cliff is an equal joint venture between locally-listed Sino Land Co and the family of its chairman, Robert Ng Chee-siong. Sino's investment properties offered for sale include Rainbow Villas, Balmoral Gardens, Villa Horizon, Silver Strand Lodge and Hawaii Garden in Sai Kung. The group recently released units for sale in The Arcadia in Argyle Street. Other investment properties likely to go on for sale include The Astrid, also in Argyle Street, and Long Beach Gardens, Bayside Villas and Grand Bay Villas in Castle Peak Road.
