FRUSTRATED property agents fought over scarce buyers for the second batch of pre-sale flats in a Tseung Kwan O complex yesterday. The remaining 996 flats in three blocks at Nan Fung Plaza were released despite sluggish sales from two blocks in June. The sale came after banker and Executive Council member Anthony Leung Kam-chung had asked the Government to lift the 70 per cent mortgage ceiling to help boost property lending and rejuvenate the market. Agents yesterday estimated fewer than 40 people had put down their 10 per cent deposits. Nan Fung Development declined to confirm the number. Midland Realty sales manager Richard Lee Chi-shing said: 'Given bad market conditions, this is expected.' He estimated about 1,000 people had inspected the flats. Only half of the 618 flats in Towers 5 and 6 have been sold in the past two months despite a 10 per cent discount and prizes of six free flats in a lottery. The flats' average price is $3,500 per square foot. The sizes range from 511 to 1,074 sq ft.
