The city of Chicago saw sales rise 10 percent in May from a year ago, according to the Chicago Association of Realtors. The median price of a Chicago home sold in May was $287,500, up 6.8 percent from May 2014.
"Chicago has seen homebuyers enter the market with vigor since February," said Hugh Rider, president of the Chicago Association of Realtors and co-president of Realty & Mortgage Co. "The increase in median prices and the relative lack of inventory compared to a year ago show consumers are comfortable with buying in the city and they believe the investment is worth paying a bit more."
