Sales to Appraised Value Ratio Analysis Application

Delaware County Auditor's GIS Office conducts a Sales to Appraisal Value Ratio analysis on a quarterly basis. Each quarter demonstrates the average sales/appraised value ratio of residential parcels for every entity in Delaware County (Ratio between 75 and 125 percent). It also shows the number of sales, average sales and appraisal value by jurisdiction.

While this information has been available in PDF file format for the past two years (files can be accessed from HERE), we have recently deployed an innovative methodology to provide this valuable information to a larger audience and with more flexibility and ease-of-use. We first found an example of this application on Richland County, South Carolina's website and our sincere thanks goes to their GIS office for providing us with technical details regarding this application.
