Renters Squatting in Recently Purchased Off-Market Deal - TEXAS

[Joseph OHare]

Hello everyone, I have a unique situation that I have not experienced before. I purchased an off-market property located in Texas through Auction.com. The property was listed as occupied. I figured this would take some work but I have managed to get people out before. The part I didn't realize was that the property is occupied by renters (and these renters do not open the front door). I don't have any of their information and the previous owner won't provide it so I can't evict or even discuss with the tenants. Can anyone provide some insight into what I should do next? Would an Attorney make sense at this point? Website where I can find their info?
