Lu Hang, vice-chairman and president of real estate services provider Century 21 China Real Estate, dismissed worries about a trading slump after the imposition of the 20 percent tax on selling a home.

"The 20 percent tax on gains may sound a lot at first but, as a matter of fact, a gains tax for selling a house in the secondary market in the US is more than 20 percent," said Lu.

According to him, in a sophisticated property market, there will be not so many new houses for trading. Therefore, the secondary market will be the main force in buying and selling homes as China's property market develops and matures," said Lu.

It seems there are many choices for investors in buying properties overseas, such as in the US, Australia, Canada, the UK, Europe and Singapore among a myriad of opportunities, but analysts suggest Chinese investors should choose traditional locations and diversify to spread risk.

However, the recent policy adjustment as well as a worsening economic environment might reduce the choice. Canada has suspended all new immigration applications recently, which will hold back many immigration-oriented investors at least over the short term.

Likewise, the increase in stamp duty for foreign investors in Singapore from 13 percent to 18 percent means an increase in investment costs and higher thresholds for foreign investors, in stark contrast with local first time homebuyers' 3 percent stamp tax, according to a China media report.

"Tax, regulations, deductions, property/asset management, procedures and tax rates and breaks can be very different and it is advisable to engage experts such as an accountant, lawyer, estate agent et cetera before buying to ensure you are getting the best deal," said Macdonald.

Local knowledge is also very important. It is best to invest where you or somebody close to you - friends and/or family - knows, he added.

The fallout from the European debt crisis may cool the eagerness of investors wanting to buy property in the continent. Properties in the UK have been hit hard in the crisis with only London staying unscathed. As the traditional European financial center, property values in central London rose 12.9 percent year-on-year in 2012, according to Tian.

It probably cost buyers an average of 20 years to get their investment back from rental incomes in London. The biggest advantage about having a property investment in the UK is that there is no capital gains tax for sales by the non-domiciled, said Yeo.

Properties in Australia are also steady and rising, according to Tian. Even during the most severe time of the last financial crisis in 2008, property values in Australia edged down just 2 percent, while properties in the UK and the US slumped between 20 and 30 percent.

"However, they have a higher than average mortgage rate of between 6.5 percent and 7 percent compared with that in China of 5 percent, between 4 and 5 percent in the US and between 3 and 4 percent in the UK, which means more cash pressure on investors," Tian said.

Higher yields in markets such as the US, Canada, the UK and Europe, possible permanent residency depending upon the type of investment - such as a green card - and comparatively less expensive investments, plus the fact that Western governments are very eager to attract investment and so have friendly overseas investment policies, combine to make certain overseas property markets enticing, said Macdonald.

The number of overseas real estate companies attending the annual Beijing International Property Immigration and Investment Expo/Spring this week will surge 30 percent from last year, lured by China's ballooning wealthy population, the expo's sponsor told China Daily.

"More than 200 booths have been booked by overseas companies, hitting a new record," said Wei Kefei, director of the expo's international department.

In addition to the traditional exhibitors from the US, Canada and Australia, there are new participants from East Europe this year, such as Lithuania, Latvia and Bulgaria.

The tightening Chinese measures, according to Wei, may further strengthen some people's determination to buy property overseas.

"But the recent policy impact will not be huge because most Chinese buying overseas properties are not doing so purely for investment purposes," said Wei. "There is an increasing number of purchases because of the polluted environment at home."

Analysts also remind investors looking to emigrate that there is hardly any country that guarantees a green card simply for investing in a property within its borders.

The effects of a flurry of Chinese buying homes abroad is being felt outside the Chinese mainland, pushing up real estate prices in Southeast Asia, Australia and New Zealand, according to a report by Knight Frank.

Partly fueled by inflows of Chinese investment, prime real estate values in Jakarta rose 38 percent in 2012, compared with 20 percent in Bali and 12.7 percent in Auckland, New Zealand. Even Hong Kong, where legislation designed to limit foreign real estate investment came into effect this year, saw gains of 8.7 percent in the prime sector, the report showed.

Top markets worldwide such as London and New York remain as havens for investors from around the world. Analysts are seeing signs of a resurgence in prime markets elsewhere as well following inflows of capital from emerging economies in Asia and the Middle East, according to the report.
