In Illinois, the seller is responsible for paying the transfer tax at closing. The transfer tax rate is tiered, ranging from 0.45% for properties sold for $499,999 or less to 1.425% for properties sold for $1 million or more. For example, if the sale price is $200,000, the seller would pay $1,000 in transfer tax.
Please note that these are just averages, and your actual closing costs may vary depending on several factors. It is best to consult with an experienced real estate attorney or title company to get a more accurate estimate of your closing costs.
