Built for people who read the documents

A German listing tells you what the seller wants you to know. The Exposé sells the balcony, the Energieausweis sits in a separate PDF, and the WEG minutes — the one document that says what the building will actually cost you over the next ten years — arrive as a scan the evening before the Besichtigung.

Buyers end up doing the same manual work every time: reading sixty pages, copying figures into a spreadsheet, and trying to remember which obligation under the GEG applies to a gas boiler installed in 2004. Most of that is mechanical. It is exactly the kind of work software should do — as long as the software shows where every number came from.

KaufWach reads what you give it — portal link, Exposé, Energieausweis, floor plan, WEG minutes, photos — and fills a typed property profile with a document, a page and a confidence score behind each value. It then prices what a listing leaves out: purchase costs, energy-driven retrofit obligations, renovation ranges.

What the documents cannot settle becomes a question for the viewing rather than an assumption. The analysis is a starting point for your own due diligence, not a replacement for it — which is why the evidence link sits next to every single field.

KaufWach is invite-only while we work with a small group of buyers and Kaufberater across Germany. The product changes weekly, and the people using it decide much of what we build next.

If you are buying in a German market and want to try it on a listing you are actually looking at, tell us where — we will send access.
