Every assumption is named, and a link opens the charts on immoprobe.de.\n\nThe location gets checked too: land value, protected areas and listed buildings, flood zones, noise maps, rent index and Mietpreisbremse reference, census, public transport and the cadastral parcel \u2014 from open data published by public bodies, with attribution.\n\nKeep what looks promising in your Immoprobe account: notes, links, files and lists, no double saves, financing variants to compare, and a side-by-side table that also opens on the website. Works in German and English.",
