I use a attorney, as I have to. I own property in an LLC and they are managed by my S-Corp. If I owned them personally, I could do it myself.
Now you own it, the 'tenants' are yours. You can talk to the former owner and see what their plans are. You have entered into the more risky side of Real Estate buying. That's where the most money is made, and also the most unknowns.
Maybe you can rent it back to them? The bank may continue to evict, as it is on their 'train' already, and they may not even realize you own the property now. Or you can talk to the sheriff and take over their eviction position.
If you are not 100% sure, use an attorney.
