Here is exactly which public registers we build the developer risk score from, how often, and how we infer sales.
Prices
We update prices daily and show them exactly as the developer published them. Every price has a date.
A unit that leaves the price list is marked as sold. That is an inference, not a confirmation: developers are not required to say what sold. Each dataset's newest file is read as the whole current offer: a unit it no longer lists is marked as sold, including when no flats are left in the file at all. So is a unit no file has listed for 30 days. Developers publish daily, so a month of silence means a sold-out investment or an abandoned dataset, not a gap in publication. A unit listed without any price is not an offer.
Companies and groups
Developers build each project through a separate special-purpose company. From the National Court Register (KRS) we read each company's shareholders and follow the ownership chain up to the parent — that is how “Pekabex Inwestycje XIV” is placed in the Pekabex group. KRS also gives the registration date, share capital and any liquidation, restructuring or bankruptcy.
Public-records score (0–100; higher = fewer red flags)
Built only from facts anyone can check. The components and their maximum weights:
| Component | Max. points |
|---|---|
| Legal status of group companies | 25 |
| Age of the parent company (years) | 15 |
| Developments | 15 |
| Share capital of the parent company | 10 |
| Sales pace (share sold) | 10 |
| Adverse events in 2 years | 10 |
| Joint-stock company at the top of the group | 5 |
| Price cuts in 90 days (share of stock) | 5 |
| Developments with a prospectus | 5 |
Levels
75–100: low · 60–74: moderate · 45–59: elevated · below 45: high. Without a KRS check no score is given. The weights are a starting point, not a verdict — every component is shown on the developer's page.
“Elevated” or “high” most often means a young company with little capital and a short record in the register — not that something is wrong. It is always worth asking.
AI review
On request, Claude (Anthropic) searches the press, consumer-authority (UOKiK) decisions, insolvency registers and buyer reviews, and writes a review citing its sources. Links the model did not actually retrieve are removed. It is a researcher's note, not legal advice.
Limits
Only some developers give the floor and number of rooms. Locations are derived from addresses (© OpenStreetMap). For information only; not an offer or legal advice.
