@Hesmeralda20 Sorry for your frustration. 😔 Unfortunately that's not possible with how Sims 4 is made - or so I was told when we've dreamt of this in feedback in the past. You are not alone, though, in wishing there could be some way to work it out in a future edition, if there comes a time. 💡
However, I have gotten a little creative with a couple of friends where we made sims or homes specifically for each other and uploaded/downloaded them to each others' games. That can be fun, especially if you chat and share updates with each other. 🤔
