Energy renovation and extension, KFW 261 example

So, we have just received our approvals for KfW 261 and NRW.Bank sustainable living.
But we do not have to finance the purchase price, only the renovation or construction costs.
152,500 at 2.41 via KfW, 30 years term and 10 years fixed interest
280,000 at 1.74 via NRW.Bank, 30 years term, 30 years fixed interest

We achieve KfW 70 EE WPB. It is sufficient if you have successfully applied for KfW 261 to be able to use NRW.Bank Sustainable Living for the remaining renovation costs.

When I had the NRW.Bank on the phone today, I specifically asked whether I really have to achieve KfW 40. They clearly confirmed that to me. How did you manage that? Or will they go along as soon as KFW 261 follows? That surprises me a bit now!

If you buy a house as a first-time buyer, the amount for the purchase can only be financed through Nachhaltig Wohnen if you achieve KfW 40. The funds we receive through the program are intended for renovation measures on a house. In that case, the achieved efficiency house level does not matter.

We or our bank applied for both at the same time. However, I had prior email correspondence with NRW.Bank and received confirmation. The response came within less than 24 hours via the info email address.

Unfortunately, I am not allowed to share this here, as NRW.Bank prohibits sharing.
