Property tax question - Evansville IN

Hi All,

I was looking at a potential property in Evansville, IN and saw a credit in the property tax that said "Res/Rental, Cap 2" and gave a credit of 832.44 towards the tax (pictured below).

I was curious if anyone else in the area knew about what this credit was? I tried calling the tax office of the county but the individual who answered the phone didn't seem to know and transferred me to a supervisor, for whom I left a VM but hadn't heard back yet.

Thanks!
