Median sales prices climbed in June for the 16th consecutive month, the Iowa Association of Realtors (IAR) said today, with the number of sales dropping 7.3 percent from a year ago. "Realtors across the state are reporting a tight inventory of homes for sale, which may account for some of the decline in year-over-year sales," IAR President Don Marple said in a news release. The median sale price increased to $147,125 over the year, and the average price rose 5.6 percent to $169,648. Houses are selling at 96.5 percent of asking price, a 0.6 percent increase from last year.
