How much access do you expect during inspection?

[Joe Henry]

When you are viewing and getting a multi-family unit inspected, from duplex up to 10+ units, how much access to the building do you expect to see? e.g. If there are existing tenants are you able to enter their apartments for the inspection? What are the typical practices, and what would be some red flags to watch out for (e.g. someone trying to hide something from you by denying access)?
