Comparable Characteristics

For your convenience a "Comparable Sales Worksheet", is available and can be accessed through the Forms page.

For each comparable sale you use, be sure to include the parcel or account number, the address of the property, the date of sale, and the sale price. Also include comparable characteristics of the property. Comparable characteristics to consider are land, improvements and other supporting evidence.
