What do you mean by "pushing a wave"?
I am only complaining about the lack of communication/transparency. I find it more than borderline to mention this small but significant detail like "[Jahresbudget]" only in passing or upon request.
Guess how many home builders, whose financing is already stretched to the limit, were enticed with (let's take the average) 24,000 euros in Baukindergeld... - even the BSK heavily advertise it...
An old grandma would have to knit for a long time to earn 24,000 euros... There could be quite a nasty awakening...
