What moves a Guide price
The same inputs decide the reference on every listing: comps, size, time, and coverage.

Direct answer
A Guide price moves when recent completed sales move. It is built from same-building transactions, adjusted to your size band, and only shown when the sample is strong enough to be a usable reference.
Recent sales, not asking prices
Guide starts from completed transactions in the same building. Asking prices are hopes; Guide is built from sales that actually cleared.
Size band adjusts the number
When a building has few exact-size matches, Guide uses a size band from the same building — and the listing makes that explicit.
Reading + green and − red
- + green — the ask sits under Guide, better for the buyer
- − red — the ask sits over Guide, stretched
- No Guide — recent sales are too thin, so we show nothing rather than guess
When it does not move
Guide is not a forecast. It reflects what has cleared; it does not predict what a seller will accept.
