This is how I read the sentence
If the household [...] owns a self-used or rented residential property in Germany for permanent use, funding with Baukindergeld is not possible.
actually too. However, as mentioned, the word "purchase" contradicts this, and it is still restricted by referring to Germany – so my New York penthouse right by Central Park apparently doesn’t matter to them
And what does "for permanent use" mean in this context? Would they recognize that a 2-room attic apartment with 60m² is not intended "for the long term" for a family of five?
Also interesting: What exactly applies to existing properties now? We signed the notarized purchase contract before 01.01.18, but only received the building permit for the "major renovation" in July, and of course, we haven’t moved in yet. In other contexts (e.g., Energy Saving Ordinance), the special status of a "comprehensive renovation" is indeed considered and mostly equated with a new building – is that the case here as well?
I definitely don’t want to work at the KfW hotline at the moment, the info sheet is somehow useless...
