For MIL, all items any family members actually want have been identified, and they will need to arrange to get these things (e.g. bring a van or truck or hire a mover), but really, no one wants anything…or they already have what they want.
All clothing that is clean and not damaged will be taken to a shelter already identified.
Next up will be a dumpster for anything that really isn’t in good shape, or is incomplete (think…mongrel dinner plates).
Everything else will be removed from the house, probably using an estate person. That is the easiest way.
In our case, no staging as this is a CCRC, and they will come in, remove any carpet, clean and paint, make sure appliances are working, and see if anyone in the community wants to relocate to this smaller house first. If not, they look at their waitlist.
The “outlaws” have clearly said…this will not be something they help with. There are a bunch of siblings who can do this.
There are restrictions about what can happen (no tag sales) but that’s fine. No one in the family would want to do one anyway.
