How my residential property is valued

State law requires that county assessors appraise all property at 100 percent of its true and fair market value in money, according to the highest and best use of the property. Fair market value or true value is the amount that a willing and unobligated buyer is willing to pay a willing and unobligated seller. The county assessor values real property using one or more of three professional appraisal methods.
Real property includes land, improvements to land, structures, and certain equipment affixed to structures. Personal property includes furnishings, machinery and equipment, fixtures, supplies, and tools. The primary characteristic of personal property is its mobility. Personal property tax applies to personal property used when conducting business or to other personal property not exempted by law. Most personal property owned by individuals is specifically exempt. However, if these items are used in a business, personal property tax applies.
