Cluttered, lots of stuff. But Not seeing the piles of trash. (I had a friend who had stacks of newspapers everywhere. She couldn't throw them out, till she to read them, but never did.) They make it seem like all these things are salable. In USA, NYC, Los Angels, SoCa, there are not Auctions Houses that sell these low end household things, low end collectibles and furniture in the US. There are vendors who will buy out whole estates lots, but there has to be some good high end pieces. Styles change, as noted, For instance the big glass display cabinets are in low demand US and UK. Because people overall do not have big collections of small things. Selling one by one on eBay, etsy, can be slow and very competitive. Poor condition, ordinary doesn't sell. )Car) Boot sales, US garage sale, stuff can sit un-purchased.
These people are lucky to have a team who work to sell their stuff. These people having made a decision seem to have no problem doing a 180 turn around. US Hoarders, many have OCD, personality disorders.
