Immigration consultant Thomas Kut had one of his busiest days ever on Sunday, starting with an early-morning meeting in Guangzhou and winding up at 8pm in Hong Kong. The occasion was a visit the chief executive of Midland Realty subsidiary Midland Immigration Consultancy organised for a group of 40 Guangzhou residents to see two upmarket Sino Land projects, the Dynasty in Tsuen Wan and the Palazzo in Fo Tan. The two-day visit, jointly arranged by Midland and Sino Land, was one of many such marketing tours organised by Hong Kong developers in a bid to attract cash-rich mainlanders to buy their luxury homes during the eight-day Golden Week holiday that started on Thursday last week. Developers offered those who joined the tours free transport and discounted hotel accommodation plus 'pocket money' to help cover their expenses. The initial response to the tours was 'not bad', according to developers. Property consultants said the trend of mainland buyers coming to Hong Kong could be sustained as long as the central government continued to loosen its credit policy and exchange controls. Henderson Land Development and Cheung Kong (Holdings) said mainland buyers bought more than 30 per cent of units sold during the holiday, while Sino Land said one unit had so far been sold to a mainlander, several other homes being the subject of 'serious talks'. Sun Hung Kai Properties said more than 10 mainlanders had committed at the weekend to buy units at Aria in Kowloon when it was ready for sale, probably in the next two weeks. The units sell at more than HK$10 million each. Victor Lui Ting, an executive director of Sun Hung Kai Real Estate Agency, said the company was still in talks with potential buyers, including some from the mainland, for the two penthouses at the Cullinan at Kowloon Station, which are being offered at HK$300 million each. So, for how much longer will this mainland buying momentum last? Alva To, the head of consultancy at property firm DTZ, said mainland buying was partly fuelled by strong liquidity in China's financial sector, and there was no sign the central government might turn off the taps on credit. 'But if it does, the trend of mainlanders buying Hong Kong properties will slow,' he said. This sentiment was shared by Benedict Ma, an associate director of property consultancy CB Richard Ellis' research unit. 'I think we have seen the effects of the more than eight trillion yuan (HK$9.1 trillion) in new bank lending in China year to date, with the rebound in stock and property markets on both sides of the border,' said Ma. 'As long as [Beijing] maintains a relatively loose monetary policy, which I believe [it is] committed to do for the time being to maintain domestic economic growth amid an uneven global outlook, then mainland investment in Hong Kong's luxury residential real estate will most likely continue,' he said. On average, about 10 per cent of luxury home sales on Hong Kong Island (in areas such as the Mid-Levels, the Peak, Southside and Jardine's Lookout) are made to mainland investment buyers, CBRE says.
