A Valuation Report draws upon available sales data in a local market, and uses it as a comparison to the property being valued. That is, how do the characteristics, sale price, sale date and other attributes of the property being valued compare to the properties that have sold recently, and over time? Measuring value changes over time allows the Valuation Report to assess the trend of activity that has occurred. Analyzing current sales against the property being valued allows the Valuation Report to account for market activity. The Valuation Report then utilizes these attributes to render a current value estimate.
