All facts about Bonava

We check the developer's own website once a day: whether the homepage answers, when its TLS certificate and its domain registration expire, and when it was last updated. A site that stops answering or lets its domain lapse is a reason to ask questions, not proof of anything.

Checked 12 Nov 2026. Method and data: One request to the homepage per domain per day, user agent KolaboroResearchAgent, after reading robots.txt (weekly). TLS expiry from the certificate the server presents; domain expiry from the registry RDAP record (weekly); sitemap weekly. No page text is kept.

Projects in Berlin with a published price within 30 % of this one (same currency) and a higher transparency score (this project: 46 of 100). The score counts what is published and checkable, not a recommendation. How the transparency score works

No project in Berlin has a similar published price and a higher transparency score.
