Tax liens and deeds properties

[Tamika Rue]

Hello everyone. So I just got back my certificate back a week ago. I tried reaching out to the owner. I went to property and put a notice to vacate on their door. Someone contacted me back yesterday

 She said her mother is staying there and her uncle is the owner(either she way lying or really don't know), but in the records it says the owner is a woman. So bascially I just explained to her that I'm legally entitled to possession and if they are going to redeem then I will not go through with eviction but if they don't then I'm going to go through with it. If the tentant is paying rent to the owner, can the owner evict with me having the certificate?
