Most households are sitting on hundreds, sometimes thousands, of dollars worth of sellable goods. Not antiques or rare collectibles — just ordinary stuff that accumulates over years and quietly takes up shelf space, closet space, and garage corners.
With resale platforms more accessible than ever in 2026, turning clutter into cash has never been more straightforward. Here are nine categories worth a second look.
1. Old Smartphones

A phone from three or four years ago still holds real value. Devices from Apple, Samsung, and Google retain strong resale prices even when cracked or non-functional, since refurbishers buy them for parts.
Sites like Swappa, Decluttr, and even Apple’s own trade-in program will quote a price in minutes. A used iPhone 13 in decent condition can still fetch $150 or more. Check the drawer — most people have at least one forgotten device in there.
2. Name-Brand Clothing and Shoes

Fast fashion resells poorly, but name-brand and designer items are a different story. Levi’s, Patagonia, Nike, and New Balance hold value on platforms like Poshmark, ThredUp, and eBay. Shoes especially.
A pair of Air Jordans or New Balance 990s in good condition can move fast and for real money. Even gently worn outdoor gear from brands like Arc’teryx or The North Face tends to sell quickly because buyers know what they’re getting.
3. Exercise Equipment

Treadmills, rowing machines, and stationary bikes are among the most consistently in-demand secondhand items. People buy them new with strong intentions, use them for a few months, and then they become expensive furniture.
A lightly used Peloton bike, even older models, still sells for several hundred dollars on Facebook Marketplace. Dumbbells and weight sets also move reliably, sometimes faster than larger machines because they’re easier to transport.
4. Video Games and Consoles

Retro gaming has been on a steady climb. Original PlayStation, Nintendo 64, and GameCube hardware and games now command prices that would have seemed absurd a decade ago.
Even more recent consoles like the PlayStation 4 and original Xbox One sell well since not everyone needs the latest hardware. Loose cartridges, especially for SNES or N64, can be worth serious money depending on the title. It’s worth checking individual game values before bundling everything together.
5. Power Tools

Brands like DeWalt, Milwaukee, and Makita hold value extremely well in the secondhand market. A cordless drill or circular saw that’s been sitting in a garage since one renovation project is exactly what a weekend DIYer is looking for.
Condition matters, but buyers on Craigslist and Facebook Marketplace are generally forgiving on cosmetics as long as the tool functions. Sell the battery separately if it’s a name-brand pack — those can be worth $50 to $100 on their own.
6. LEGO Sets

Sealed LEGO sets appreciate at a rate that routinely outpaces more traditional investments. Retired sets, ones that are no longer sold in stores, can sell for two to three times their original retail price. Even open, complete sets sell well if all the pieces are there.
The Star Wars and Harry Potter lines tend to perform especially well. If there are boxes of LEGO in a closet somewhere, it’s worth cross-referencing the set numbers on BrickLink before pricing anything.
7. Musical Instruments

Guitars, keyboards, and drum kits bought during pandemic-era hobby surges are now flooding the resale market, which means buyers have options, but sellers with quality gear still do fine. A mid-range acoustic guitar from Yamaha or Seagull will find a buyer.
Vintage or American-made instruments hold value even better. Reverb.com is the dominant platform for instruments and tends to attract more serious buyers than general marketplaces.
8. Kitchen Appliances

Stand mixers, espresso machines, and high-end blenders are worth listing individually rather than donating. A KitchenAid stand mixer in working condition sells for $100 to $200 used.
A DeLonghi or Breville espresso machine moves fast on OfferUp. The general rule: if it originally cost more than $80 new, it’s probably worth the ten minutes it takes to photograph and list.
9. Furniture

Solid wood furniture sells. Particleboard generally does not. A real oak dresser, a solid walnut coffee table, or a well-built bookcase from a brand like Pottery Barn or Crate & Barrel will attract buyers on Facebook Marketplace or Chairish.
Buyers in 2026 are increasingly skeptical of flat-pack furniture, which has driven more interest in secondhand pieces with actual longevity. Measure the piece, take photos in decent light, and price it about 30 to 40 percent below comparable retail.
