I don't have the kind of house you are looking for, but a good place to start is to do a gallery search with hashtags unfurnished, empty and shell. Yes, you will get all homes and not just ROM ones, but there aren't that many up yet that are ROM and they are quick to find. The homes will need furnishing but you can always add and upgrade as you go. It's also generally easier to tell if the home uses a lot of MOO. I grabbed a few homes that I liked today as I am not good at building complex houses and I won't download furnished ones.
