Two reports tracking the housing market show local median prices continued rising in August.

The median price for a resold house in San Diego in August increased by 0.78 percent from July to $448,500; the increase in the median price from August 2013 was 8 percent, according to CoreLogic Dataquick.

Meanwhile, the Greater San Diego Association of Realtors, which does separate tracking of single family houses and condos, reported the median for a detached, single family house in August was $510,000, up 4 percent from July and up 6 percent from August 2013.

SDAR said the median for condos sold last month was unchanged from July and stood at $340,000; the median price was up 10 percent from August 2013.

Both surveys found sales activity was down considerably from the same month a year earlier. Dataquick said sales last month fell 18.9 percent from August 2013 to 3,324.

SDAR found sales of single family houses decreased 19 percent from a year earlier to 1,769, while condo sales were down 22 percent to 849 in August.

Total listings as of the end of August stood at about 8,400, which SDAR estimated to be about three months of inventory. Homes were selling in an average of 40 days.

The most expensive listing sold last month was a seven-bedroom, seven-bath house in La Jolla for $9 million, SDAR said.
