How bad do you want to save on your property taxes? That is really the only question that matters. If you have the proper comps in hand with supporting documentation and your comps are more correct than the county or as correct then you will prevail. Honestly, I over heard a county employee, in one of my many visits to the accessor office, tell another employee in a conversation I was surely not suppose to hear, say, "....<Property Taxes> They are always higher that what it should be, it's up to the homeowner to sort that out....WOW I was flabbergasted. But I also became empowered at that point because I now knew the secret. With the right comps and supporting documents you are destined to be successful in your appeal. I was successful and lowered my accessed value by over 100K.
