Parcels on market ratio would be a nice metric to use in determining the areas to target, but many properties are listed on each of the comp sources and are duplicated entries skewing the results. It would be great if there was a way for you to clean the duplicates from the comp list for this calculation or have a filter for a data source for comps. I'm having to manually verify POM and sold/for sale ratios on zillow or realtor because there are many duplicated for sale comps in the combined for sale comps. A good deal of these for sale duplicates are from lands of America where a single property might be listed multiple times.
When I run a report to search counties, using the county research tool, and compare these ratios I have to disregard them for now and do my own manual ratio calculation.
Not sure if or how you can do anything to improve this but I wanted to ask since you guys are always very receptive to user feedback.
