When can I access my unit?
How long is a lease/contract (aka "We're month-to-month")
How do I move out of my unit?
Do I need to bring my own lock/some variation of this?
How do I pay for my storage unit?
If possible, include a question or two about the move-in process, like when they can expect their gate code or if they need to swing by the office to sign addiitonal paperwork.
