China's OCT Properties, one of the country's leading real estate firms, announced Saturday that its net profit rose 56.73 percent year-on-year in the third quarter to 133.2 million yuan ($19.5 million).

Business revenue of the property developer increased 28.85 percent year-on-year to 1.17 billion yuan, the company said in a statement to Shenzhen Stock Exchange Saturday.

The real estate bubble has been a hot topic for a while.  It seems this announcement added more concerns to the issue.
