What to Sell to Make Money

1Start with what you already own

Before buying anything to resell, sell what is already in your house. The margin is infinite — you paid nothing to acquire it, because you acquired it years ago and already absorbed that cost. Most households can clear a meaningful amount from things currently doing nothing.

Walk through this list room by room and be honest about what you have not touched in a year:

• The cupboard with old phones, tablets, chargers and cables in it
• Kids' clothes, toys and gear that have been outgrown
• Kitchen appliances bought with enthusiasm and used twice
• The exercise equipment (yes, that one)
• Books, board games, DVDs, and video games
• Furniture that survived a move but does not fit the current place
• Tools, garden equipment and anything in the garage

The reason this beats sourcing for beginners is that it teaches you the whole process — photographing, pricing, dealing with buyers — with zero downside if you get the price wrong.

2The 42: what reliably sells

Fastest movers (usually sold within a week)

1. Prams, strollers and car seats — constant demand, high new prices, buyers who need them urgently
2. Cots, high chairs and baby carriers — same dynamic; every household using them is on a clock
3. Kids' bikes and scooters — outgrown annually, bought constantly
4. iPhones and Samsung Galaxy handsets — the single most liquid used item there is
5. iPads and tablets — strong demand, easy to value by model
6. Games consoles — PlayStation, Xbox, Nintendo Switch and their controllers
7. Power tools — DeWalt, Makita, Milwaukee, Bosch hold value remarkably well
8. Lawnmowers and garden tools — seasonal but fast in spring
9. Dining tables and chairs — always in demand from people moving
10. Desks and office chairs — a permanently strong category since remote work
11. Bookshelves and storage furniture — cheap to buy new, but buyers want them today
12. Washing machines, fridges and dryers in working order — high value, easy sale, hard to move

Strong value, slightly slower

13. Solid wood furniture — dressers, sideboards, wardrobes
14. Mid-century and vintage furniture — the highest-margin furniture category by far
15. Designer and branded handbags — authentication matters enormously
16. Quality kitchenware — Le Creuset, cast iron, KitchenAid, stand mixers
17. Cameras and lenses — film cameras have had a sustained resurgence
18. Vinyl records — condition and pressing determine everything
19. Musical instruments — guitars, keyboards, amps
20. Bicycles (adult) — road and mountain bikes from known brands
21. Laptops and monitors — value drops fast, so sell early
22. Watches — from Seiko upwards there is an active buyer market
23. Lego — sold by weight or as complete sets, both work
24. Trading cards and collectibles — Pokémon, sports cards
25. Retro video games and consoles — pre-2010 hardware appreciates
26. Sewing machines — small, valuable, consistently wanted
27. Camping and outdoor gear — tents, packs, sleeping bags from known brands
28. Golf clubs — a reliably active secondhand market
29. Fishing equipment — same
30. Aquariums and terrariums — niche but buyers pay well
31. Rugs — especially wool and handmade
32. Mirrors and framed art — cheap to source, decorative demand
33. Garden pots, planters and outdoor furniture — seasonal spikes
34. Christmas and seasonal decorations — sell them in season, not after

Worth knowing about

35. Branded children's clothing in bundles — individually worthless, bundled it moves
36. Textbooks — timed to the academic year
37. Board games — complete boxes only
38. Vintage clothing — genuinely vintage, not merely old
39. Trainers and sneakers — limited releases have their own market
40. Pet gear — crates, carriers, cat trees
41. Building materials left over from projects — tiles, timber, paint, flooring
42. Car parts and accessories — roof boxes, tyres, floor mats

3Where to source stock cheaply

Once you have sold your own things and want to keep going, you need supply. In rough order of margin:

• Free listings and kerbside. Marketplace's free section, local “everything must go” posts, and house clearances. The margin is everything; the cost is your time and transport.
• Estate and house-clearance sales. The best source of underpriced furniture and collectibles, especially on the final day when sellers want things gone.
• Charity and thrift shops. Reliable for books, kitchenware, clothing and the occasional badly-priced electronic item.
• Car boot sales and flea markets. Arrive early, bring cash in small notes, negotiate at the end of the day.
• Auction houses. General household lots often go for very little. Watch the buyer's premium — it can quietly eat your entire margin.
• Storage-unit auctions. High variance. Occasionally excellent, frequently a van full of nothing.
• Marketplace arbitrage. Buying badly-listed items — bad photo, wrong category, misspelled brand — and relisting them properly. This is the most reliable ongoing edge available, and it is largely a listing-quality skill.

The last one deserves emphasis. A huge share of items on local marketplaces are underpriced purely because they were listed badly. If you can spot a well-made item behind a dark photo and a title with no brand name in it, that gap is your margin.

4What to avoid

These look like money and generally are not:

• Large low-value furniture. A brown fabric sofa is worth perhaps $40 and takes two people and a van to move. The economics never work.
• Older televisions. Heavy, fragile, and worth almost nothing beyond recent large models.
• Mattresses. Hygiene rules and buyer reluctance make them close to unsellable in many places.
• Ordinary adult clothing. Unless it is designer, genuinely vintage, or bundled, the effort per dollar is worse than any other category.
• Printers. Cheap new, unloved used, and frequently broken.
• Exercise equipment. Enormous, extremely common secondhand, and every buyer expects it nearly free.
• Anything counterfeit or of unverifiable authenticity. Beyond the legal problem, it will get your account restricted.
• Recalled items, especially car seats and cots. Check before listing; selling a recalled safety item is a serious liability.

5Realistic margins and timelines

Clearing out your own home typically produces a few hundred in the first month or two, then tapers as you run out of things. That is not a business, but it is real money and it costs nothing but time.

Sourcing deliberately is different. A reasonable target is buying at 25–40% of what you can sell for, giving a 50–100% margin after your time and transport. The binding constraint is almost never demand — it is how many items you can photograph, write up and list in an evening. Sellers who treat listing speed as the core skill, rather than sourcing, tend to be the ones who scale.

One caution worth stating plainly: this is trading, and trading income may be taxable in your country once it passes a threshold. Selling your own used possessions at a loss generally is not. If you cross from clearing out into buying-to-sell, it is worth checking your local rules early rather than a year later.

6Common questions

What is the easiest thing to sell for money?

Things you already own and no longer use. Furniture, phones, baby gear and tools all move quickly and cost you nothing to acquire.

What sells fastest on Facebook Marketplace?

Baby and kids gear, furniture, phones, power tools and games consoles — items with constant demand, easy local pickup, and a price a buyer can decide on in seconds.

How much can you realistically make?

A few hundred from a first clear-out. Beyond that, a 50–100% margin per item is a sensible target, with your listing throughput as the real limit on total earnings.

Do I need a business account to resell?

Not to start. Local marketplaces run on personal accounts. Once you are buying stock deliberately and regularly, check your local tax and trading rules.
