Why is my House at 675 Memorial Drive being considered a building with two units?My property is at 675 Memorial Drive Calumet City, IL. 60409. The property sits on 2 lots and I pay 2 taxes, twice a year. But this is a house, not a building. Now I don't know how to value the property. It is now showing two (2) separate property values.Do I add the two together? Or average it out or what. I have been following Zillow for sometime now and need assistance with this matter.Thank you675 Memorial DriveCalumet City, IL. 60409March 11 2009 - Calumet City00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
