A REDUCTION in sales of the city's used apartments, coupled with price adjustment in a few prime residential areas, led Shanghai's second-hand housing index to advance at a weak pace for the sixth consecutive month, the local index compiler said yesterday.

The local second-hand housing index rose by 1.05 percent in June.

The monthly index, which tracks prices for used apartments across the city and is released by www.ehomeday.com, gained 25 points to 2,387 last month.

Between January and May, it increased 1.3 percent, 1.1 percent, 1.96 percent, 1.03 percent and 0.98 percent.

"Citywide, transaction volume dropped by about 25 percent in June as compared to a month earlier while second-hand apartment prices declined by around 5 percent in about one fifth of the places monitored by our Website," Chi Shengyu, an analyst with the index compiler said yesterday.

"We expect the slack momentum to remain in the second half of this year with further adjustment in both volumes and prices."

Across the city, second-hand home prices gained 2.1 percent in Putuo District last month, leading all gainers, followed by the districts of Yangpu and Hongkou, which climbed 2.05 percent and 1.89 percent.

In particular, used apartments in Putuo's Shiquan/Yichuan and Taopu jumped 2.68 percent and 2.02 percent, whereas those in the Caoyang/Changfeng communitites rose 1.93 percent.

Meanwhile, used-apartment prices in some prime locations began to falter in June, a normal correction after too rapid a growth previously, the compiler said.

For instance, second-hand home prices in Nanjing Road W. and Huaihai Road retreated 2.25 percent and 1.59 percent last month while those in Lujiazui and Xinhua Road yielded 2.73 percent and 0.53 percent.

Separately, the local rental index, also released by the Website, edged up 0.2 percent, or 2 points, to 1,217 last month.
