At the time of an assessment, the Maricopa County Assessor will generate a Valuation Notice to each property owner. A sample of such a notice can be seen here. The property value (by law) should reflect what you could sell your property for in the open market (market value), without undue pressure, and in a typical arms-length transaction for cash or its equivalent. Typically, the property value of a home is set by comparing the sales of similar properties which are adjusted for differences in function, physical age, location, etc. If a taxpayer chooses to appeal either the Full Cash Value or classification of their property, they may do so by filing an administrative appeal with their County Assessor or they may appeal directly to court (Tax Court or the County Superior Court). You can find the steps for filing such an appeal here. You may see 2005 property value information (if you have Adobe Acrobat) sorted by zip code here. If you'd like to find out the value of a particular parcel, you may use the online Residential Parcel Search function.
