Did Calhoun make the switch from tax certificate to tax lien sales in 2019 and, if so, would a certificate or deed, sold to the state in prior years, and purchased from the state by an investor now, still be handled in the manner of the certificate/deed system (that entitles possession, ejectment, etc), as opposed to the new lien system?  

Usually that means you must file an ejectment lawsuit.

And then file ejectment after 6 months to take possession/ preservation improvements. *** a few people around the block argue about assumed vacancy and hence proceed without filing ejectment and proceed to take possession (with improvements) and then wait it out for the admin redemption period to end and proceed with quiet title action.Denise speaks on the former hence I follow her guidance.

And, if so, would a future buyer of that tax deed (assuming it's not me), have to work with and/or eject me?

The best thing to do is to send them notice, then file an ejectment action and eject them from the land. 

Then if she doesn't pay I can file for summary ejectment.

At the time it was occupied and I had to wait 6 months to file for ejectment.

Hi @Jason Johnston, you need to file an ejectment lawsuit against them. 

What are the proper steps in the ejection process?

Now if they threw something in the ejection pump no concessions.
