SOC,

We conducted and exhaustive report of Chicago transactions by 21 neighborhoods. The report is categorized by size and type of housing and is available via this hyperlink - http://www.atproperties.com/marketReport/. In addition I would hazard that you consider that Edgewater carries greater power to the seller between Broadway and Clark, from Devon through Ridge than the area east of Broadway. If you are among the buildings in the Winthrop-Kenmore corridor your value is adversely impacted while west of Broadway is of greater value. The other advice of having an appraiser come in is good - this carries a roughly $300 price tag. If the buyer is financing the purchase an appraisal will be conducted as part of their receipt of funding.

Good luck.

The best and most up to date information regarding properties which have sold in a particular neighborhood can be found on the Multiple Listing Service which Chicago realtors and appraisors utilize to determine the current market value of properties. Once you are given access to this data base, I suggest you search for like kind properties first within your building and if necessary, expand your geographical parameters up to a 6 square block area that have sold over a 6 month period 24 to 18 months ago and then repaet the search over the last 6 months from todays date. You should also compare the dollar cost per square footage of those properties. Be careful to distinguish which properties ncluded auto parking and type of parking in the sales price.
You can also try the ChicagoTribune data base for sold properties if you are unable to utilize the MLS data base.
