What steps to take while purchasing a property with tenants

[Tom Server]

Hello, I'm about a month out from closing on a triplex with tenants. 2 of the tenants leases are expiring end of February and the third is on a sec 8 til Sept.  The owner has a personal property manager taking care of the property 

Should I do anything with the tenants or property manager prior to closing? 

Am I allowed to reach out to the tenants?

Am i allowed to reach out to the property manager ?

thanks in advance
