How do I tell if property has been sold?

[Karah Collins]

I was able to find some public records online dated October 2019 from the county courthouse announcing foreclosure on a number of properties. The verbiage used was "The names given being those of owners or occupants as the same appear on the assessment rolls for the levy year 2017". For what it's worth, the final date of redemption was listed as Feb. 2020.

However, after getting the looking up each home on Realtor/Zillow/Redfin, it appears none of them have been sold. Additionally, I cross checked these homes with the upcoming properties to be auctioned at the courthouse (auction was 6/5 but has been postponed indefinitely due to pandemic),and they were not being auctioned.

What should I assume is happening with these properties? Will they eventually be auctioned, and are delays COVID related, or am I misinterpreting info? 

Would love to hear the perspective of someone with more experience on these issues!
