Hong Kong’s luxury home sales almost tripled in September from a month earlier, as mainland Chinese residents flocked to buy flats in the city.

The registered sales of residential units worth more than HK$10m ($1.3m) rose to 1,351 from 500 in August, according to Land Registry figures released yesterday. A one- bedroom flat in Kowloon sold for a record HK$24.5m, Centaline Property Agency said last month.
