Be sure to hire a good home inspector with experience. One that is ASHI certified and of course is licensed with the State of Illinois. Different home inspectors charge slightly different prices, but you should expect to pay between $225 to $250 in the price range that I suspect your 1175 Sq Ft ranch home would be in. Most home inspectors charge by the price range of the home and not by square footage of the home in our area. For instance...up to 150k is $225.00
151 - 200k is $250.00 , 201 - 250k is $275.00, 251k to 300k is $325.00 and over 300k is per quote
Not all inspectors follow this above chart, every inspector charges what they feel they are worth, but also want to be competitive in pricing with other inspectors. You will need to contact each inspector to see exactly what they charge, or find a flyer or their website.
