Child construction allowance for building a new house, but..

As a few users here have already written, KfW no longer only supports the first purchase, but the only property, which could be the second one, which is sensible and fair. The 48k€ was not included in the financing plan, the new house is also almost completed. However, I still want the funding and will not simply accept an ill-considered/unclear regulation and will seek my right, which is not prohibited. Ultimately, it must be clarified whether an intention to purchase declaration before the building permit is sufficient with the "sale of the old property", because then the problem would be solved? That's what this thread is actually about, and I didn't want to have to justify why I am seeking my right..

However, I still want to have the subsidy and will not simply accept an ill-considered/unclear regulation and will seek my right, which is not forbidden.

You sound like a sulky toddler. If you don't succeed, the grants will simply go to 4 other (and maybe also more likeable) children.

that is a very unnecessary and antisocial comment. Besides, you don’t even know his children.

This is not ignorance. The subsidy applies only - and exclusively - to the first purchase of a property. I hope you have not firmly planned on the Baukindergeld?
