Great question. First of all, if you look at all the south suburbs, with few exceptions, the taxes are high. Why? One reason is most of these towns have home rule, which allows them to tax without any ceiling. As far as whether they need it or not, that you would need to ask the villages. As far as I know, there are no changes to lower them. Again, another village question.
However, you do need to look at the other side of the coin. Taxes are higher BUT prices are much lower. Taxes and purchase price are all figured into your monthly payment. Would you rather pay more taxes and less price so you can earn more equity or pay less taxes and more price so you have less equity in the home.
Park Forest prices are still low and will increase in the future, so there will be equity. Taxes can be fought and you do get a deduction from real estate taxes on your annual income taxes.
You need to run the numbers. You can get more for your money when prices are low - more upgrades, more space.
We all hate taxes. Only fighting your assessment and your local government will change that. If you need a place to live, this is a potential opportunity.
