Delinquent Tax List

I’m looking to obtain delinquent tax lists from several counties in Arizona. So far all of them offer delinquent tax data but they don’t specify whether the property is vacant land or not. Has anyone else run into this issue and if so, what do you do about it?

Any feedback would be greatly appreciated!

@rphil99 you can go to the assessor site / gis with the parcel # and it will inform what type of property it is
