When you move in to town, your first priority is to get a house, but Tom Nook says you don't have enough money. What should you do? Rob a store, a really good one. You need to rob Crazy Redds, then after you steal the paintings, you need to get the cops off of you so you need to steal the train that you took to get to the town in the first place. Then you will be in a new town where you will sell your paintings at Re-Tail and go back to your original town. You will then have money to buy a house.
