I had this issue come up with a group of roommates. There were 3 roommates, and of course 2 of them would leave every year. They asked for a walk through for the roommates who were leaving. We did it that time, but will never do that again. We had people disagree about whose fault things were, and ended up causing a lot of issues between us and the roommates. While I was at the walkthrough, I also had a tenant argue with me over the policies which she was fully aware of, and it escalated to her yelling at me and having a fit. I don’t like being yelled at. Also, it’s another hour of my day that I lose, with no real advantage to me.
We have since revised our lease to say that there will be no walk throughs until the unit is completely vacant, and we do not walk through when anyone is present. We also have one person who is a main point of contact for the deposit and rent payments. Everyone is jointly and severally liable (make sure you include that clause), however we only have to deal with one person, not three.
This is good for a lot of reasons… first, I believe that it’s impossible to determine the condition of the unit when it is still full of stuff. Additionally, we don’t want to be involved in disputes about who did what. Last, if issues arise, it may sour the situation between ourselves and the remaining tenants for the duration of their stay. It is much simpler to deal with one person, and only at the very end. Set it up in the lease and tell them in advance, they will learn to sort it out themselves.
