It will take quite a bit of work and will not really give you a true picture, as some towns have multiple school districts and are in several counties. The way that I think would help you the most is to have your favorite Realtor send you the listing data on the homes in your price range , have the features you want/need/dream of and in the areas that make sense from a commuting standpoint. Then you could skim down the list and decide what is too much. Generally Cook County is lower for residential property than the surrounding counties. Schaumburg and Elk Grove do not levy a village tax, like most of the neighboring towns, so they can be hundreds or a thousand less. If you want a list of available homes with all the data and inside pictures, let me know.
