Most guides to reselling on Facebook Marketplace stay vague — “electronics flip well,” “look for deals.” This one doesn’t. Below is a category-by-category breakdown of what actually moves, what typical margins look like, and where the pricing gaps come from that you can exploit.

Electronics: iPhones and Unlocked Smartphones

Typical buy range: $150–$400 (iPhones two to three generations old) Typical resell range: $250–$550 (eBay, Swappa, or local)

iPhones hold their value unusually well and have a deep secondary market. The gap on Marketplace comes from sellers who don’t know the difference between carrier-locked and unlocked (unlocked phones are worth more), sellers listing with bad photos and no specs, and urgent sellers who price to move rather than to maximise.

Before buying any iPhone, verify the IMEI is clean (no blacklist, paid off) using a free IMEI checker. Confirm it’s iCloud unlocked by checking Settings → Apple ID. A phone with an active iCloud lock is worth nothing to a reseller.

Watch out for: Aftermarket screens (harder to detect but affect Face ID), swollen batteries (check at the back seam), and activation lock.

Electronics: Game Consoles

Typical buy range: $150–$300 (PS5, Xbox Series X) Typical resell range: $280–$420

The easy console arbitrage from the shortage years is gone. The margin now comes from bundles. A seller listing a PS5 with five games and two controllers for $300 because they’re moving and don’t want to deal with individual listings is common. You buy the bundle, sell the console separately, sell the games and controllers separately, and capture the unbundling premium.

Older consoles (PS4, Nintendo Switch, Xbox One) have a buyer base of parents shopping for kids who don’t need the latest hardware. A clean PS4 Pro with a controller and a few games can be bought for $100–$150 and resold for $180–$220 without much effort.

Watch out for: HDMI port damage on PS4s (common failure point), Switch consoles with bent pins in the dock connector, and disc drives replaced with incompatible units.

Electronics: Monitors

Typical buy range: $50–$150 (27” 1440p or 4K monitors) Typical resell range: $120–$280

Monitors are underrated in resell circles because they’re bulky and annoying to transport. That’s exactly why the margin exists — fewer people compete for them. A 27” 1440p IPS monitor from a known brand (Dell, LG, ASUS) that retails for $350 can frequently be found for $80–$120 from someone upgrading or clearing out a home office.

Test before you buy. Dead pixels, backlight bleed, and input lag issues are not visible in listing photos. Bring a laptop and run a dead pixel checker.

Watch out for: Burn-in on OLED monitors, cracked stands that need replacement, and monitors with only VGA outputs.

Power Tools

Typical buy range: $30–$120 per tool or lot Typical resell range: $80–$300

Power tools are one of the most reliable flip categories because the brand premium is real and buyers know it. A Milwaukee M18 drill and driver set retails for $250–$350 new. On Marketplace, the same set shows up regularly for $80–$120 because someone inherited tools they’ll never use, finished a renovation, or is liquidating a contractor’s estate.

Battery compatibility within a platform (Milwaukee M18, DeWalt 20V Max, Makita 18V) creates bundling opportunities. A battery that fits multiple tools sells separately for $40–$80. A seller listing a tool without its battery for $30 — because they kept the battery for another tool — is an easy pickup if the tool itself is in good shape.

Watch out for: Bent chuck on drills, worn brushes on older brushed motors, and damaged battery contacts. Test every tool before buying.

Sporting Goods: Gym Equipment

Typical buy range: $50–$200 (dumbbells, benches, barbells) Typical resell range: $100–$400

Home gym equipment had a demand surge in 2020–2021, and a lot of it is now sitting unused in garages. Cast iron dumbbells, rubber hex dumbbells, adjustable benches, and power racks show up constantly at well below retail.

Cast iron is priced by weight — roughly $0.50–$1.00/lb at retail, often $0.25–$0.50/lb on Marketplace from people who don’t know that. Equipment sold in lots (someone selling an entire home gym setup at once) often has the best margin because the seller prices by gut feel.

Watch out for: Cracked welds on power racks, bent barbells (check by rolling on a flat surface), and cable machines with frayed cables.

Bikes

Typical buy range: $60–$200 Typical resell range: $150–$500

Bikes flip well because condition is immediately apparent to buyers and because a clean, properly adjusted bike is worth significantly more than the same bike with flat tires and a misaligned derailleur — all of which you can fix for under $40 in parts and an hour of time.

Focus on mid-range bikes from recognisable brands: Trek, Specialized, Cannondale, Giant. A Trek aluminum road bike that retails for $700 and has been sitting in a garage for five years will sell for $150–$200 on Marketplace. Clean it up, tune it, and it sells for $350–$450.

Watch out for: Carbon frames with cracks at stress points (bottom bracket and tube intersections), and bikes stored outdoors with rust deep in the cables and housing.

Musical Instruments

Typical buy range: $50–$300 Typical resell range: $150–$800

Sellers who received instruments as gifts, bought them for a hobby they didn’t stick with, or are cleaning out an estate rarely know what they have.

Electric guitars from reputable brands (Fender, Gibson, PRS, Epiphone) hold value well. An Epiphone Les Paul Standard listed for $80 because someone thought “it’s not a real Gibson” can sell for $200–$280 in good condition. Vintage and semi-vintage gear (1970s–80s solid-state amplifiers, old pedals) often sell for multiples of what Marketplace sellers think they’re worth.

Watch out for: Headstock cracks on guitars (structurally compromising), oxidised frets, and brass instruments with stuck valves from neglect.

Camera Gear

Typical buy range: $100–$400 (mirrorless bodies, DSLR kits) Typical resell range: $200–$900

Camera gear has one of the strongest secondary markets of any category, largely because enthusiasts upgrade frequently and often sell locally rather than dealing with shipping. A Canon R50 kit with the 18–45mm lens that retails for $680 shows up on Marketplace for $350–$450 from someone who decided photography wasn’t for them after six months.

Lenses often have better margin than bodies because the price is less intuitive to sellers. A vintage manual-focus lens with an adapter that sells to enthusiasts for $150 on eBay might be listed for $20 because the seller has no frame of reference.

Watch out for: Sensor fungus (visible in photos shot at small aperture against a bright surface), delaminating lens elements, and shutter count on bodies (free tools can read this from a test photo).

The Role of Speed and Analysis

Across every category above, the common thread is that the best deals disappear fast. A $100 Milwaukee M18 kit or a $150 Trek road bike will get serious inquiries within an hour of listing. By the time you’re browsing Marketplace the next morning, it’s sold.

Consistent reselling income requires two things: being alerted immediately when something matching your criteria appears, and being able to quickly assess whether the price is actually good or just looks good. An app like Spottable handles both — it monitors Marketplace continuously and sends an immediate push notification when a match appears, with a price analysis that compares the listing to comparable sold prices. That combination — fast alert plus quick context — is what separates flippers who find good deals consistently from those who occasionally stumble on one.

Spottable is available on iOS. Set up searches for the categories you flip and start seeing what comes up in your market.
