OK, hold up.
I don't see anything wrong with Lowe's hiring people ("corrupt tax-experts"!) to look for grounds to ask for a lower assessment. When I file my taxes, I look for legal ways to reduce the amount owed. Sometimes, like with the mortgage interest deduction, it seems strange that I am getting a break now but not when I was a renter.
So, dwelling for clearly non-insignificant time on minutia of taxation is A-OK in your book, but spending maybe an hour or two on researching energy/water ratings on lasting-more-than-fiscal-year home appliances is some recondite voodoo normal people shouldn't be expected to handle on their own? How does that work?
