Just put an offer on duplex with tenants, how should I prepare?

[Jonathan Perez]

I put in an offer on a duplex. And there are tenants on both sides. One of the tenants are being evicted. The other side is on a year lease....there is a property manager already in place which I may consider keeping.. IF my offer is accepted, how should I prepare to enter this. Should I introduce myself to the tenants? Should I not? Should I set up a business account for the rental income? Should I set up an LLC? What are some systems I can put in place? I was planning on house hacking it, so I'll be living in the side where the other tenant is being evicted from.
