The Price we pay.

Well received my 2012 Property Assessment and Tax Notice today.
Couldn't open the envelope fast enough to see if the 2.5% tax increase was real or not.
First of all my assessment went down $1420 on a $327,000 property a difference of less than half a percent so a virtual non factor.
So I took last years taxes $2,721 times 2.5%, I should be looking at a tax increase of $68.03 shockingly my taxes went up to $2,873 a difference of $152. My trusty calculator tells me that is an increase of  5.6%? why am I surprised? have we been misled?

Will be interesting to see what other people have experienced?
