Buy underpriced items on Facebook Marketplace, Craigslist, and thrift stores. Sell at market value. Keep the difference. This is the complete guide to building a flipping business.
Flipping means buying something below market value and reselling it for a profit. The gap between what you pay and what you sell for is your margin — and every experienced flipper knows that gap is widest on local platforms where motivated sellers price items to move fast rather than to maximize returns.
Facebook Marketplace flipping is the most common entry point. Sellers are often downsizing, moving, or cleaning out a garage — and they'd rather get $50 now than wait weeks for the right buyer. That's your opportunity. Source it locally, clean it up, and relist it at what the market will actually bear.
The catch: the best deals disappear in minutes. Speed is the single biggest variable that separates flippers who consistently score good inventory from those who are always a step behind. Setting up keyword alerts with price filters and location radius — rather than manually refreshing — is how serious flippers stay ahead.
Each category has its own sourcing strategy, margin profile, and best-selling platform. Start with one and go deep before branching out.
iPhones, Samsung Galaxy, MacBooks, gaming consoles, and cameras. Technology depreciates fast — creating a steady supply of underpriced, fully functional gear. A cracked-screen iPhone 13 bought for $150 can often be screen-repaired and resold for $350+.
Sourcing tip
Set up alerts for specific models with negative keywords like -locked -parts -cracked to filter out non-functional inventory.
Sell on
Solid wood furniture, mid-century modern pieces, and name-brand home goods are the highest-margin local flip. Sellers are often motivated (moving, divorcing, downsizing) and price to move fast. A $50 solid oak dresser sourced from Craigslist can sell for $250+ locally.
Sourcing tip
Search for "solid wood" -IKEA -particle -veneer and act within the hour — good furniture is gone the same day.
Sell on
Phone flipping is the entry point for most resellers — low capital, quick turnover, and a reliable buyer pool. Focus on iPhones and Galaxy S models from the last 3 years. Even phones with cosmetic damage are worth buying if they're functional.
Sourcing tip
Look for listings with phrases like 'needs new screen' or 'cracked back' — cosmetic fixes cost $20–$40 and double your margin.
Sell on
The highest dollar-per-flip category. Buy cars with known, fixable issues (bad battery, worn tires, minor cosmetic damage) from motivated private sellers and relist at market value. Requires more capital and mechanical knowledge but delivers outsized returns.
Sourcing tip
Search for "needs work," "project car," or "motivated seller" — these signal below-market pricing.
Sell on
Authentic luxury goods and limited-edition sneakers hold value exceptionally well. A Chanel bag sourced at a consignment shop for $400 can resell for $1,200+. Nike Jordans and Yeezys bought at retail often resell for 2–3× on the aftermarket.
Sourcing tip
Develop authentication skills before investing heavily — buying a fake wipes your entire margin and then some.
Sell on
Vinyl records, trading cards, vintage toys, antiques, and sports memorabilia. The ceiling is unlimited if you know your niches, but requires deep category knowledge. One misidentified piece of Depression glass can make your month.
Sourcing tip
Estate sales and thrift stores are the best sources. Set alerts for specific brands, makers' marks, or keywords like 'estate sale' and 'lot.'
Sell on
The best flippers treat each platform differently — different sourcing strategies, different buyer pools, different competition levels.
Facebook Marketplace is the most active local resale platform in the US, with hundreds of millions of listings monthly. It's the primary sourcing ground for furniture, electronics, and cars — and the best place to sell locally without shipping.
Strengths
Watch out for
Craigslist is older and scrappier than Marketplace, but that works in a flipper's favor. Less competition, more motivated sellers, and a deep catalog of free items, cars, and heavy goods that Facebook's audience doesn't always cover.
Strengths
Watch out for
eBay is the best platform to sell on — not usually source from. Its global buyer pool and auction format let you sell at true market value, making it the ideal destination for items sourced cheaply on local platforms. The eBay Refurbished and Authenticity Guarantee programs add buyer trust for electronics and sneakers.
Strengths
Watch out for
Know your sell price before you buy
Check eBay's sold listings filter for what your item actually sold for — not what it's listed at. That's your ceiling. Work backward from there to your buy price target.
Target motivated sellers
"Moving sale," "must go," "free," and "estate" signal sellers who prioritize speed over max price. These listings are where your best margins come from.
Use negative keywords to filter junk
Electronics: -broken -parts -icloud. Furniture: -particle -veneer -IKEA. Cars: -salvage -rebuilt -flood. Smart filtering means you only see the deals worth acting on.
Have a message template ready
The first serious buyer usually wins. Draft a short template: item name, offer price, available pickup times. Send it within 60 seconds of seeing the listing.
Reinvest your first profits
The compounding effect is real. $300 → $450 → $675 → $1,000. Put your profits back into inventory before taking cash out, and your buying power grows fast.
Track every flip
Log buy price, sell price, platform, and time-to-sell for every item. After 20 flips you'll see which categories make you the most per hour — and double down on those.
Yes — experienced flippers routinely clear $500–$3,000/month as a side hustle, and full-time resellers can do significantly more. The key is finding deals below market value consistently, which requires knowing where to look and having a system to act on listings quickly before other buyers do.
You can start with as little as $100–$300 by focusing on small, fast-turning categories like electronics accessories or clothing. Most serious flippers start with $500–$1,500 to have enough capital to buy multiple items simultaneously.
Facebook Marketplace flipping means buying underpriced items listed by local sellers on Facebook Marketplace and reselling them at market value — either on Marketplace itself, eBay, or another platform. The profit comes from the gap between what motivated sellers list things for and what buyers will actually pay.
The most consistently profitable categories are smartphones and electronics (quick turnover, high demand), solid wood furniture (large margin, easy to source locally), sneakers and designer goods (strong resale platforms), and cars (high dollar value per flip). Each requires different sourcing strategies and skill sets.
The best deals on Facebook Marketplace and Craigslist disappear within minutes. To beat the competition, you need real-time alerts rather than manual searching. Set up keyword-based saved searches with price filters and location radius so you're notified the moment a matching listing goes live. Both platforms have built-in notification tools, though dedicated monitoring apps check more frequently and cover multiple platforms simultaneously.
Margins vary widely by category. Electronics typically yield 20–50% ROI. Furniture can be 100–400% if sourced cheaply and sold locally. Designer goods can go higher but require authentication knowledge. A good rule of thumb: aim for at least a 30% return on your cost before factoring in time.
