Tax delinquent list

[Fitzgerald Hall]

Hello everyone this is my first post, but i have been a member for about a year now. Biggerpockets is filled with great information but unfortunately I have not found an answer to my question.

I have a list of properties that are delinquent or late on their taxes. Any advice or suggestions on how to scrub the list? A criteria for what to look for would be very helpful, i.e time of delinquency, including or excluding llc, delinquency amount, etc, etc. Thanks in advance!
