Thanks for the reply/idea. That's what I would probably do.
Problem is the senior isn't ready to push their friend yet. They want it gone and admit their friend is a hoarder but won't force the issue. The hoarders family has hinted or admitted that one day they will have to deal with her stuff, knowing them they would pay for a dumpster and crew. But they can't even get the family member to deal with their stuff in their apartment so it's a waiting game until they finally get an eviction notice or declared incompetent from an physical illness.
