Advice on Inheriting Tenants AND Property Management company?

[Mike S.]

I am in the middle of a deal where I am inheriting tenants and a property management company.  

I have to abide by the lease from a landlord/Tenant Perspective.  However, I don't want to continue with the Property Management company and the sample contract I have is silent on the sale of the property.  Do I inherit the terms of the Property Management contract similarly to the tenant lease?

Should the current owners be notifying the PM that the contract is ending?

Thanks in advance!

Mike
