Construction start before KFW application efficiency house?

Hello,

I intend to build a house, would like to take the first steps on my own property using credit first and only start financing once all the documents are gathered.

Is such an approach obstructive because then the KFW funds for the energy-efficient house can no longer be granted?

Yes, that can be an exclusion criterion.

Since you are stingy with details, just a note here that the Kfw provides all necessary information on their website. Keywords: funding conditions, "How it works," examples, FAQs ... the website is literally covered with hints of this kind.

Dan cannot, that is definitely a disqualifying reason.

What you can usually do beforehand are preparatory measures such as demolition of an old building, clearing, etc... As soon as you start construction (e.g. basement excavation, soil replacement) you have forfeited the chance for the KFW.

But what is good is that you can first only apply for the KFW and test the rest and finalize later.

One of the (not comprehensible) statements was:

Yes, it can also be done later, it must be within 3 months and must not be more than 50% completed ...

The spoken word is not worth the time in which it was spoken, at least as far as the [KFW] is concerned. There it is quite clear.

What counts is what is written...
