how accurate is the auditor's valuation?

[Joseph Davis]

I am new to real estate and right now I am just trying to learn as much as I can. I am not sure if this question is too broad but are the property valuations on the county auditor site usually very accurate? I will sometimes look at their valuation and compare it to the selling price to see how much they correlate. I just want to know if this is something that may be safe to go by or if you should just talk with a professional in the area. Thanks!
