What's your Process with inherited tenants?

[Dominic Sabre]

I'm new to investing and in escrow on a few MF properties.  Feeling nervous about taking over 10 tenants.

What's your process when you inherit tenants? 

Do you have them sign a new lease or just get the old one assigned? 

Do you run credit checks?

What else do you do when you inherit tenants at closing? 

When do you do step in your process?  Before closing, at closing, or after?  

Thank you!!
