What are sold comps?
Sold comps are recently completed sales of the same or similar item, like eBay sold listings, used to estimate what something actually resells for. The rule that matters: always price off sold comps, never current asking prices.
Why asking prices lie
An asking price is what a seller hopes to get; a sold comp is what a buyer actually paid. Overpriced and unsold listings sit on a marketplace forever, dragging the visible "prices" upward, so if you value resale off asking prices you'll consistently overestimate, and then overbid. Sold comps cut through that: they're demand, not hope.
Why they're the anchor of a flip
Your profit gap is real resale minus landed cost. Sold comps are how you get the "real resale" half honest. That is why a valuation built on past auction prices misleads. It measures what people paid to acquire, not what the item resells for. Why matched sold comps beat AI guesses →
