Cook Country Property Tax Increase

I'm a bit late, but looks like there was a massive property tax increase in Cook County recently (abc7). I'm considering purchasing properties on the south side via a couple turnkeys that I am still vetting, but am quite concerned about this eating a large chunk of the profit.

Is anyone familiar w/ how this is being applied - is it a flat % increase? Or are there parts of town that may be more or less impacted?
