KfW Funding Climate-Friendly Residential Building from March 2023

You can calculate all of this.

Conclusion in advance: If everything writes is correct, QNG seems to be worthwhile for him.

Each calculated for 10 years until full repayment, same installment amount in calculation 2.
Option 1:
KFW 300 + QNG (220,000):
Monthly installment approx. €1850
Interest payment approx. €2000

Option 2:
KFW 300 (170,000) + regular loan (35,000, assumed at 3.5%):
Installment amount 1430 + 420 (this component, however, paid off in 8 years)
Interest payment approx.: 1550 + 5160 = 6170€

But from my point of view, that is not the question.

The question is whether the conditions are met here. Keyword the combination of income limits complied with, children of the appropriate age, and at the same time the financial capacity to build and repay the KFW 300 loan within a maximum of 10 years. That would be a very rare combination.

QNG is worth it for him.

It isn't. What's the use of saving €4000 in interest if you pay €10000 just for the certification?
I think KFW 300 without QNG is the cheapest solution.
QNG is worth it if it is "already" included anyway. The lady from Weberhaus said that it is already fully included with them.

It doesn't. What's the use of saving €4000 in interest if you pay €10000 just for the certification?

QNG only makes sense if it's "already included anyway." The lady from Weberhaus said that it's already completely included with them.

... aaarg. And that's why I shouldn't write after an early shift anymore.
You're of course right.

KFW 300 without QNG + the remaining amount with a regular loan is better.

I'm going to a corner to be mad at myself for not sticking to my clear rejection of QNG.

Hey Gerald, banks don’t finance 40k€, only from 50k upwards.
Or a private lender, but the interest rates are too high there.
I’ve already been through everything.
I find it really interesting here in the forum, it’s extremely obvious that the people who sometimes reply here apparently don’t inform themselves at all about finances.

Alright, I think a 160k€ KFW loan and 50k€ from the bank are also cheaper. But to each their own. Nobody is forcing you to take full advantage of the subsidy. I'm pretty good at math, I don't know which bank grants which amounts. But go ahead and pay for your QNG certificate. It's the best solution (for math dyslexics).

You are quite cute. You should first look to yourself and educate yourself.
