"Homeowner Exemption" for property taxes

[Russell Pitts]

Hi, I am in my due diligence phase of a turnkey property in Hazel Crest, IL.  The property currently has a "Homeowner Exemption" which appears to be some property tax discount for those that make the place their primary residence.  Taxes seem to be $243/month, but I'm assuming that once I buy it as an investor (it won't be my primary residence) that taxes will go up?

Anyone have any clarity on the subject?
