We served the previous owners with a writ of ejectment and they had thirty days to respond.

I know if the property is still occupied i would have to notify them (owner and/or lien holder) to redeem the property or face being  evicted via filing a ejectment law suit and have to wait 6 months.

And no, the police have no authority here.....it would be an eviction/ejectment proceeding if it goes that far.

-Do not talk to the tenant if it is not the owner- If you have a tax certificate then you can not evict, you can file an ejectment lawsuit.

A lot of hard money lenders today are able to lend on  auction properties depending on the circumstances, but be forewarned there could be a number of issues such as your inability to see the interior and how much it may need or the homeowner may still be present and you may have to get an ejectment after purchasing.In short, I would strongly recommend not purchasing at auctions UNLESS you're going to make it a chief strategy of yours and really put in time learning the details, going to auctions and just watching how they unfold, etc.

Yes you can make improvements and rent it out but first you must gain legal possession by either asking the last title holder of record to surrender the house to you or wait 6 months then file and ejectment.   

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?
