@Phil Gaulrapp, your tax rate is not based on property type, rather, it's based on the location of your property within its' taxing district (For cook county, see: http://cookcountyclerk.com/tsd/DocumentLibrary/2015%20Tax%20Rate%20Report.pdf). The assessment ratio will differ depending on your property classification and the equalization factor is the same throughout Illinois.

You may be able to look up the property on the county treasurer's office and figure out the "tax formula" for your property; if available, it may show the tax rate.
