Which public registers the developer risk score is built from, how often the data is updated, 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 has 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 units 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 development or an abandoned dataset, not a gap in publication. A unit listed without a price is not counted as on sale.
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 warning signs)
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 |
| Track record (developments) | 15 |
| Share capital of the parent company | 10 |
| Sales pace (share sold) | 10 |
| Adverse events in the last 2 years | 10 |
| Joint-stock company at the top of the group | 5 |
| Price cuts in the last 90 days (share of units) | 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.
