Hoping to buy a 5-plex, questions about transfer of ownership

[Rachel Payton]

I have an offer in on what will hopefully be my first commercial investment property.  I'm wondering how the transfer of ownership is going to work in terms of relations with tenants.  When is it ok to start communicating with tenants?  Is it the current management company that informs them of a change of ownership? and therefore management?  Or is that responsibility with me, the new owner?  Any other information relating to this would be helpful!
