Unsold real estate in Ningxia has swelled this year as a raft of newly completed apartments enters the still sluggish market, the Ningxia Bureau of Statistics said.

Real estate developers in Ningxia invested 30.52 billion yuan from January to November this year, 30.3 percent more than a year before, but sales dropped, leaving 5 million square meters waiting for sale by the end of November, 56.5 percent more than last year.

Unsold real estate includes 3.33 million square meters of residential property, 81.7 percent higher than last year.
