I buy everything off my guys and don't really replace it. Requests to find them a new furniture item go ignored. Mostly they end up with just one or two items of furniture and a few fish/bugs. Does that count as a wreck? I figure at least anyone who ends up adopting one off me can restock the house as they see fit!
On the plus side, if you completely empty their houses out they start putting up more interesting stuff in ReTail. Barold had a sloppy chair there this morning MINEMINEMINEMINEMINE
Octavian, ankha, and apple's houses all look great.
I'd say the most messed up atm are coco and diana's.
Coco's gyroids have all been replaced with clothes, there's a spa chair and billiard table replacing the exotic screens. (HOW DID THIS HAPPEN) Also diana has fish, some random painting, and a green closet that doesn't fit with anything. I'm trying hard to get their houses cleaned though.
Vic's house is in very near 100% original condition. It's awesome. My god, Francine, lmao.
The most random furniture in a villagers home probably belongs to Roscoe. I think it's gotten better recently, though, but I haven't been able to check.
The majority of the villagers in my town have now really ugly mishmash houses. I'm just glad that the ones I consider to keep are still original or... most of it. I so regret giving them bugs and fish or furniture that were out of place in their houses. I always try to give them now nice or some of their original things, but... sometimes it would show up in Re-Tail or they replace something nice instead of a random thing.
