Learn me something about this tax bill in Broward County Florida

[Miguel "Mike" Perez]

This tax bill is at least twice the amount for all other (30 or so) properties I have been evaluating.

Is there something to see between the lines?

Here is the tax bill:

Furthermore, it is the only tax bill I've looked at that has these very heavy yearly increases.

21% increase from 2012 to 2013 but when there is no cert, the tax increase is minimal like from 2013 to 2014 it only went up less than 1%.

It also has these early certificate issued, certificate redeemed.

For example, in 2014 the cert read $6353 but then $6677 was actually paid.

What are those and are those why are they causing the tax bill to rise at an alarming rate?
