always protest your tax assessment. It always helps when their property card is wrong, inaccurate Sq footage, state that I had 3 fireplaces.
I won my appeal last year, what was interesting (my experience) they really don't want to have to hold an actual hearing/meeting (which is what Indiana law prescribes).
they send out their 'guy' to handle/mediate with the taxpayer and basically cut the deal and end the matter. actually turned out to be a very efficient process. follow the procedure (to a 'T') or you'll get bounced, and it basically was one phone call, and email exchange of data, and a couple pictures, and we were done.
