Noob question about uploading a lot

[oshizu]

So far, I've only uploaded just-finished-being-built lots to the gallery.
I've been wanting to upload my 7-bdrm 6-bthrm legacy house to gallery.
I understand that I should use a copy of my save and delete crafted stuff, collectibles, garden, and stuff like that.

My question: What happens to stuff in my family inventory?
                    Will those objects all be automatically deleted when I upload to gallery? Or do I need to manually delete them myself?

Items in the Household Inventory do not get uploaded with the house, but they will remain in the save for the next time you play the family.
