See the pie chart in the post again -- citizens of Galesburg are paying 9.89% property tax on their home, not 0.5%. There are a lot of other taxes that make up the total property tax. Your 1.6% is incredibly low, in my experience.
My state, they can go up to 7.5% so I didn’t really think too hard about it, but I think I’m desensitized to how crazy high that is…
