If you want to learn how to make money flipping cars, the biggest lesson is that profit is made when you buy, not when you sell. Look for undervalued cars from private sellers on Facebook Marketplace, Craigslist, or local listings—often people just want a quick sale. Focus on vehicles that run well but need simple things like detailing, new tires, or small cosmetic fixes rather than major mechanical repairs. Clean the car thoroughly, take clear photos in good lighting, and price it slightly below similar listings so it sells quickly. Be patient, do your research on market prices, and avoid rushing into bad deals. With smart buying and careful costs, car flipping can turn into a steady side income.
