I know that there are some special NPCs that live together. For example if you scan Reese and decorate her house, both Reese and Cyrus will live there. Then if you scan Cyrus in after you'll be redesigning the house you made for Reese earlier.
But can anybody confirm or deny if these guys share houses?
Copper/Booker Pelly/Phyllis/maybe Pete another pairing that I missed
I'm mostly just curious so I can know the minimum number of special NPC cards someone would have to buy to decorate all the extra houses
There are 68 special NPC cards. Getting rid of duplicate characters, there are 42. Getting rid of characters that share a house, that's 30-33 depending on if the last two pairings are right or not. If you wanted to get amiibo cards just so you could decorate the houses you'd otherwise miss out on, you could save your money and only buy about half of the special cards.
