Duplex is exactly that—two homes sharing a wall. It’s probably not much different than SFH

I lived in a duplex from age 5-9 and it was pretty much a SFH type experience. I would only say that if the two homes are stacked vertically, like a Chicago two flat, the experience may “feel” a bit more like apartment living. If you have to climb a set of stairs to get to your home, then you’re already experiencing something that SFH dwellers don’t usually have to deal with.
