In the past 12 months, 268 attached units (condos, co-ops, townhouses) sold in Evanston with a median price of $208,750--this does not include foreclosures or short sales, which, if included, brings that median price down to $180,000. During the 12 month (prior) 12 month period from June 23, 2010-June 24, 2011, there were 266 units sold with a median sales price of $260,000; including the foreclosures and short sales brings that price down to $239,700. You can see that while the number of units sold has remained constant, the sales price has declined significantly. Besides what has happened in the general economy, I believe that the addition of many new units to the area (not just in Evanston, but also nearby communities that might be in a buyer's search pool ) such as Optima Woods in Skokie near Old Orchard Shopping Center have altered the supply/demand dynamics.
Currently there are 269 units for sale in Evanston ranging from $44,900-$1,200,000, with 195 of them priced under $300,000. With interest rates still very low and a sizable selection, it's a good time to buy. Let me know if you'd like any further information or help in exploring some good options for you.
