THE sale of a Kowloon residential site for a record $3.94 billion is encouraging developers to release their projects for pre-sale. Sun Hung Kai Properties is offering 100 residential units of the Sea Crest Villa development in Tsuen Wan. The flats at Block 9, from 544 to 828 square feet, are being offered at an average of $4,156 per sq ft. Unit prices range from $1.97 million to $3.77 million. Cheung Kong (Holdings) is selling 52 luxury flats of its Goldwin Heights building at Seymour Road in the Mid-Levels. The luxury units, measuring from 991 to 1,048 sq ft, are being offered at an average of about $6,300 per sq ft. Both developers are now registering potential buyers. Sun Hung Kai is providing special arrangements for buyers to reduce the 70 per cent mortgage lending barrier. After a down payment of 15 per cent, buyers of Sea Crest Villa units can choose to pay a further 15 per cent in three tranches by next October or by way of monthly instalments for 12 months from February.
