In college I earned a good amount of money by flipping our car. I took the old beat up piece of junk car we already owned and listed it on Craigslist for about $800 more than I thought it was worth. It took a while to sell at the higher price, but it eventually did! Then I bought another car with the additional $800. I flipped my car about 4 times per year (my state only allows 5 sales per year before you have to be a dealer) and each time rolled the earnings into a new car. Eventually we had a much better car and it hadn’t cost us a dime.
