When a property is sold, a Sales Disclosure form is filled out and filed with the County Assessor. The Personal Property and Sales Deputies use the information from the Sales Disclosure to determine the validity of the sale for trending. Phone calls, questionnaires, and personal interviews are also conducted to ensure the accurate validity of property sales. This process is extremely important as Annual Trending is based on market sales. The more accurate our information is, the more accurate our property values are.
