This only works if you get a villager from the campsite or another town.
1. Ask a villager from the campsite or another town to move in. Then save and exit the game.
2. Set your 3DS clock a few days forward (I usually do about 3).
3. Reopen your game and select New Save File.
4. Go through Rover's questions with your new character. When you arrive in town run around to find the house plot.
a) If you like the spot, go to Tom Nook's, build a house, save and quit.
b) If you don't like the spot, press the Home button to quit without saving and repeat the process.
