Why "active listings" are the wrong comp
If you search eBay for an item and sort by price, you're looking at what people are asking — not what buyers are actually paying. Overpriced listings sit unsold for months and still show up in that search. A realistic comp has to come from items that actually sold, at the price they actually sold for, recently enough to reflect the current market.
Finding real sold comps on eBay
- On eBay, use the "Sold Items" filter (under Show Only) rather than the default active-listings search — this limits results to completed sales.
- Check the date range. A sold comp from 8 months ago for electronics or anything trend-sensitive is close to useless; prioritize the last 30-60 days.
- Match condition carefully. "Used" covers everything from barely-touched to barely-functional — a sold comp for a different condition tier will mislead you.
- Throw out outliers. One unusually high or low sale (often an auction with only one bidder, or a bundle) will skew your sense of the real market price.
- Factor in what the comp doesn't show: eBay and payment processing fees, shipping cost if you're not doing local pickup, and the time the item sat before it sold.
Why this is tedious to do by hand
Doing this properly for one item takes real time — filtering, reading through recent sold listings, averaging, then separately calculating fees and shipping to get to an actual net number. Doing it for every listing you're considering, every day, is what actually stops most people from flipping consistently. It's not that the math is hard; it's that nobody has time to do it 20 times a day.
What FlipperIntel does with this
FlipperIntel scans eBay and Facebook Marketplace listings continuously and automatically compares each one against recent comparable sold prices, then factors in fees, transport, and typical holding time to show expected net profit — not just a price gap. You get a buy/pass recommendation with a risk tier, instead of doing the sold-comps research by hand for every item you're considering.
