What to do when there aren't enough sold comps
Thin data is the trap that produces fake-precise prices. How to widen a sparse comp set honestly — and when the right move is to admit the number isn't there yet.
The most expensive mistake in resale pricing isn't a wrong number — it's a confident number built on two comps. When the data is thin, here's how to widen it without fooling yourself.
Widen the window before the definition
Stretch to 180 days before you start mixing in different variants. More time on the same item beats more items over the same time.
Add adjacent variants, but flag them
A close printing or grade can fill out the picture — as long as you keep it separate in your head and discount it, rather than pretending it's the same item.
Know when to stop
If you still can't assemble a handful of real, comparable solds, the honest output is 'not enough data,' not a guess dressed up as a price.
FlipWorth shows the sample size and spread on every estimate, and says 'not enough data' outright when the comps can't support a number — so you never list on false precision.
