A real estate group says home prices fell in eight out of every 10 U.S. cities in the third quarter of this year, as heavily discounted distressed sales made up 30 percent of all deals.

But home sales continued their climb, with quarterly sales outpacing the second quarter and the previous year's figures, the National Association of Realtors said Tuesday.

The median sales prices of existing homes declined in 123 out of 153 metropolitan areas compared with the same period a year ago. Prices rose in the other 30 cities.

The national median price clocked in at $177,900, or 11 percent below the third quarter last year.
