Major league sports get a $40m annual property tax abatement, churches get an annual combined half billion dollar property tax abatement. Taxes are wildly different from block to block, there are not dozens, but 147 different categories of abatements. There are 7 abatements that have a single claimant per annum (hmm...) and 42 abatements that have less than 10 claimants (more hmm?).
There's so much more, definitely worth a read. I imagine the info will cheese off some people.
Great work indeed!
