To check what tasks need to be completed, tap the Quest icon (the one that looks like a text). There you can access Elroy's quest to see what he needs before he moves in.
In addition to Elroy's room & placing a computer in his room, you'll need to buy his diary & place it in his room as well as give him the green atoms wallpaper.
