Vietnam has eased restrictions on foreign ownership of property in an effort to lure the cash needed to revive a market saddled with oversupply since a real estate bubble burst in 2011. The country has been battling with lingering bad debt after years of easy credit and lax oversight came to an end three years ago, sparking a crash in the property market and leaving the banking sector unable to provide the credit firms needed to grow. Investors with business interests in Vietnam from Singapore, China and Japan were the most likely to buy property, attracted by the potential for higher yields in Vietnam than at home, property firms and analysts said. Singapore and Japan are the second and third-biggest sources of foreign direct investment in Vietnam after South Korea. Lawmakers amended the law on foreign property ownership last week to allow foreign investment funds, foreigners with valid visas, international firms with operations in Vietnam and overseas Vietnamese to buy residential properties. The changes will take effect in July next year. Overseas Vietnamese send home about US$11 billion a year in remittances. "A lot of that [remittance] money can go into property for them, so I think that's the big headline and the motivator for this," said Troy Griffiths, a deputy managing director of property firm Savills Vietnam. The law, however, limits foreign ownership to 30 per cent of an apartment building, and a maximum of 250 homes in one city neighbourhood "ward". "If the government doesn't set limits, big investors or the Chinese could just sweep in and buy the whole of Hanoi if they wanted," said Luu Minh Ngoc, the chief executive of property firm Bac Son Group. "So the limit on foreigners is appropriate and should only be relaxed gradually and in sectors." The property market had shown signs of improvement before the changes. The value of property in inventory fell to 83 trillion dong (HK$29.6 billion) by September from 170 trillion dong in March last year, according to media reports. Property market participants welcomed the new law as a boost to liquidity and to clearing some of the property from the market linked as collateral to bad debts. Foreigners working in Vietnam have been permitted to own houses since 2009, but red tape and usage restrictions for foreign-owned homes dissuaded buyers, with just 100 out of about 80,000 foreigners managing to own a house as of October last year.
