What Is Reselling and Flipping?

8 minute readUpdated June 2026Explore more

TL;DR

Reselling is buying an item for less than you can sell it for, then selling it on. It is less about luck and more about knowing what things are worth and where to find them cheap.

Hi, I'm Nicole. Reselling sounds fancy, but it is one of the oldest side incomes there is: you buy something for a low price, then sell it to someone who wants it for more. The gap between those two numbers, minus your costs, is your profit. Facebook Marketplace makes it easy because the buyers are already local and already scrolling. Your whole job when you start is to learn what things are worth and where to find them cheap.

The simple loop behind every flip

Every flip follows the same four steps: find an item priced below its resale value, buy it, clean it up, and list it where buyers are looking. That is it. The skill is not magic, it is repetition. The more items you look up, the faster you learn which ones are worth grabbing.

  • Something you can buy cheap or free
  • Something people actively search for and buy secondhand
  • Something you can look up recent sold prices for before you commit

Why Facebook Marketplace is a great starting point

Marketplace is free to list on, the audience is local, and there are no shipping headaches when you start. You meet a buyer, hand over the item, and get paid. That short distance between listing and cash is why so many beginners start here before touching eBay, Poshmark, or OfferUp.

What decides your profit

Your profit is the sale price minus what you paid, minus any cleaning supplies, gas, or fees. Because you set the buy price, most of your profit is actually made at the moment you buy, not when you sell. Buy smart and the rest gets easy. Overpay and even a great listing cannot save the flip.

Common questions

  • Do I need experience to start reselling?

    No. You need a phone to look up prices and a little patience. Start with one item you already understand, look up what it recently sold for, and learn from there. Experience builds fast once you make a few flips.

  • How much money do I need to start?

    You can start with very little, even free items given away locally. Many beginners begin with things they already own or items priced under twenty dollars. Small, cheap flips let you learn without much risk.

  • How long before I sell my first item?

    It varies. A well-priced item in demand can sell in days, while a niche item takes longer. There are no guarantees, so price using recent sold comps and be patient. Consistency matters more than luck.

  • Is reselling worth it as a side income?

    It can be, if you learn what sells and buy at the right price. It is real work, not free money, and profit depends on your buying discipline. Treat it seriously and it can add steady side income.

  • What if my area feels saturated with resellers?

    Competition usually means there is real demand. Narrow your focus to a category you understand well instead of chasing everything. Knowing one type of item deeply beats knowing a little about many.

  • Can I resell part time?

    Yes, most people start on the side. Block a few hours a week for sourcing, listing, and meetups. Steady weekly effort beats one frantic weekend, and it keeps a fresh flow of items listed.
