Propibay pulls arm's-length transactions from powiat price registers, filters them for homogeneity and shows which comparables support your number — before anyone asks hard questions.
Pick the role — see how comparables change the room before you commit capital or reputation.
Stop negotiating against listing prices and anecdotes. You get a range built from deeds that actually closed — with every weak comp visibly rejected.
“I knew 296k was defensible — and why 410k from the portal wasn't.”
Show which plots support the price and which ones the engine threw out. The conversation shifts from trust-me to here's the evidence.
“The seller stopped arguing when they saw three accepted comps on one screen.”
Homogeneity checks, recency windows and similarity scoring are visible — so your first draft starts from structured evidence, not a blank spreadsheet.
“Selection funnel and comp list in one place — hours back on every file.”
Toggle evidence mode and click comparables — see what stays in the model and what gets cut.
Rejected comps stay visible — click any row to see why it failed.
Three sources, three numbers, zero audit trail.
