Interest conditions with KFW over 20 years (1.38% effective)

I just came from my bank and thought that some of you might be interested in how the interest conditions look with the new KFW loan. I specifically obtained offers for 20 years. Total investment volume is about €450,000, of which €220,000 is to be financed.

The conditions are as follows:

Offer Number 1:
€120,000 through the bank at 1.62% for 20 years
€100,000 through the KFW at 1.06% for 20 years
Mixed interest rate of 1.38% effective -> no special repayment on the €120,000 / KFW can be repaid early at any time

Offer Number 2:
Identical to above, only 1.86% effective for the €120,000 loan over 20 years
Mixed interest rate of 1.50% effective -> but up to 5% special repayment allowed

I am currently filling out the financing application! With these conditions, early repayments hardly pay off anymore – so I am currently leaning towards the 1.38%. :)

How do the 1.06 at [kfw] come about?

and how high are the additional costs to meet the KFW requirements?

- he is probably subsidized by the bank again. - I am building with Ytongg 36.5cm -> KFW would already be possible with an air-water heat pump and a controlled ventilation system. I am also installing a ground-water heat pump as well as a photovoltaic system with battery storage. The ground-water heat pump does not cost extra compared to the air-water heat pump (I install the necessary collector myself and import the heat pump). Due to the subsidy (BaFa), it is even cheaper for me. The photovoltaic system basically finances itself as well (10,000 houses program with €10,500 subsidy as well as KFW loan with repayment grant -> although I am still checking whether both can be combined).

Which bank is that?

You're really investing a lot! Don't forget the additional thermal insulation and the approval by [KFW]. It wasn't worth it for us at all. We finance entirely without [KFW].
