Liu added that the price decline in September 2012 was the direct cause of the year-on-year surge for the same month this year.

New home prices edged down 0.7 percent in Beijing in September 2012, while in Shanghai the figure was 1.9 percent. The decline was 0.7 percent in Guangzhou and 2.2 percent in Shenzhen.

Another 51 cities experienced a year-on-year price decline in September 2012, which worked out to 1.8 percent for the group as a whole.

Liu said that price trends are diverging among cities. He said that the largest increases are mainly taking place in first-tier cities and several second- and third-tier cities, with prices in the rest of the cities increasing at a moderate pace.

Average month-on-month new home price rises in Beijing, Shanghai, Guangzhou and Shenzhen reached 1.4 percent.

The average for the 31 second-tier cities covered by the NBS was 0.7 percent, while for the 35 third-tier cities, the figure was 0.6 percent.

Analysts said the market will cool off.

"Especially in the secondary market, home prices are well above the reach of ordinary buyers at the moment. The growing difficulties in obtaining mortgages at the end of the year will also make buyers hesitant to conclude a deal," said Lu Qilin, research director at Shanghai Deovolente Realty.

Most analysts believe it is unlikely that the central government will announce any further tightening policies involving the real estate market in the foreseeable future.

Runaway prices led the government to issue guidelines in March to further tighten control of the real estate sector, including higher transaction taxes, restrictions on purchases of multiple homes and higher down payments. But the guidelines failed to arrest the surge.

The government is likely to expand its property tax trials amid recent gains in home prices in many cities, according to experts.

Government documents on reform have repeatedly touched on the subject, further evidence that this approach is locked in, said Jia Kang, head of the Research Institute of Fiscal Science at the Ministry of Finance.

But Ding Zuyu, executive president of E-House (China) Holdings Ltd, said that it’s unlikely to see the governments of first- and second-tier cities will achieve their goals of reining in prices. As a result, these cities are likely to announce separate measures.

"It is becoming clearer that the former administrative-oriented policy is going to be replaced by a market-oriented system, and the central government aims to set up a long-term mechanism for building a healthier property market," said Ding.
