How do you find properties before they are auctioned?

[Christopher Hosea]

I am trying to find a resource/website that list properties that have missed a tax payment. Every website that pops up on my search engine only shows NOD/short sales and bankruptcies. I would like to be able to identify properties before they get to that point. County Tax Assessor websites only list auction dates (which there are not going to be many now, thanks covid). I was told by my broker that Realist used to be able to show a properties missed payment but I do not see that information accessible anymore. Am I looking in the wrong spot or not searching the right key words. Any advice would be great.
