Revaluation is a periodic program undertaken in order to appraise all real property in terms of its full market value (bringing all properties to 100% of their true market value and by the same standard.) Market value is defined as the price a purchaser who is willing but not obligated to buy, would pay an owner, who is willing but not obligated to sell, taking into consideration all uses to which the property is adapted and might in reason be applied. Also known as tax equalization, revaluation ensures that all property owners pay their fair share of taxes based on the actual true market value of the property they own.
It consists of appraising the value of the properties, both taxable and exempt, using recent sales, building costs and income and expense information of similar properties. All residential, commercial, apartments, industrial, vacant land, churches, school buildings and all other real estate are valued.
The property tax is designed as an "ad valorem" tax, which means it is a tax based on the value of the property. The premise is that if someone owns a $1,000,000 property, he or she would pay twice as much in taxes as someone who owns a $500,000 property. Therefore, the market value of property is the standard that is used to determine one's fair share.
