Estimating (Correctly!) Property Tax in St. Louis, MO

[Carl Flint]

Hello people of BP!

I have been running deal analysis for properties in St. Louis, Missouri. I am very new to analyzing and have never owned a property. So, some things, like property tax, are hard to estimate fairly. Are there any suggestions that you have for me to learn more on this? Is there any place I can go? Anything I can read?

My fear is running the numbers on a deal and thinking I have a good deal, based on the final numbers, but really just having inaccurate information that makes it look like a good deal that really isn't.
