Depends how professional the current PMC will be about the transistion.First, have client get all leases.Then rent ledgers.Make sure you get a copy of their current management contract, so you understand the Termination requirements - you don't want to break any state agency laws and have the curent PMC file anything against you.Make sure the client follows the Termination requirements BEFORE you take over.Suggest the owner emails their Termination notice to current PMC and copies you on the email.

I can refer you to some of my seasoned self-storage clients if you send me a direct message.
