Zhang Hongwei, research director of Shanghai-based property consultancy ToSpur, estimated that major developers' sales revenue will grow 20 to 30 percent this year. Seven companies are likely to achieve sales exceeding 100 billion yuan, against three last year.

"Big names including Poly, Evergrande, China Overseas, Country Garden Holdings and others will be on the list," said Zhang.

New home prices in the 10 biggest cities rose 13.87 percent year-on-year to 18,179 yuan per square meter in September, extending the gaining streak to 11 months, according to the latest report from the China Index Academy, the research arm of Soufun, China's largest property website.

Beijing saw the biggest month-on-month property price rise of 3.75 percent, followed by Shenzhen, which posted a 3.15-percent month-on-month gain. Price increases in Guangzhou and Shanghai stayed between 1 and 1.5 percent.

With the traditional high season for residential sales coming up, and with some cities scheduled to host housing fairs in October, international real estate service provider CBRE anticipates more upgrading demand in the fourth quarter.

It said that the possible extension of property taxes into new markets is pushing up price expectations. The expansion of the property tax net is also likely to accelerate purchasing plans by first-time buyers and upgraders, adding further pressure on the market.
