The state's house sales increased 18.3 percent over the year ending in July and prices were up nearly 11 percent, the Iowa Association of Realtors said. This year alone, sales have climbed 8 percent and prices have risen 5 percent, the association said in a news release. Throughout Iowa, 4,074 homes were sold last month, compared with 3,444 homes sold in July 2012. The average sale price was $168,823 in July 2013, and $152,361 last July. "June and July 2013 recorded the two highest average and median sales price figures ever recorded by IAR since it began the current data tracking system in 2005," IAR President Don Marple said in a news release. Inventory was tight, with six months of supply. In many areas, including Greater Des Moines, inventory is even lower, providing greater advantage to sellers, who received on average 96.2 percent of the asking price at the time of sale. New active listings were up by 14.7 percent, climbing to 5,717 from 4,985 in July 2012. Pending sales were up by 3.7 percent, hinting at continued strong sales activity in the next couple of months, Marple said.
