Today I was at an exhibition where the KfW bank has held a lecture
the newest conditions of the KFW bank is 1% for credit and up to 12,5% instant money payback from the kfw bank to you.
if you build an house model "KFW-55% energy consuming" for 4 apartments then you get 300 000€ for 1 % and the KFW bank pay you 12% back means 37 500€ instand in cash on hand!
your house makes profit and it pays it self back to the KFW bank because you build the house with an
BHKW power plant and a Solar power plant and a Wind power plant!
Yes the KFW bank is the greatest-best bank in the world!
if you are clever they pay a "plus energy house"
A plus energy house.
