Appealing County Assessor's Valuation

[Alan Walker]

Hi All,

I just got a notice from Salt Lake County Auditor's office that value on one of my properties increased by close to 20% and so my taxes are also increasing.  I know the market is hot in SLC but a 20% increase in value in a year seems steep.  Does anyone have any experience appealing the new market value on these valuations?  I know there's an appeal process but it asks that you submit evidence of "your opinion of value".  Not really sure what that would be.

Appreciate any guidance or experience you can share.
