Tell me, why should I care about the bank's yield at KFW? Sorry, but for me these are no limits, for me this is useless, non-applicable knowledge. It has nothing to do with professional competence and margin here margin there, the interest rate remains the same and I only need to care about the amount of compensation I receive for this component of my work.
The consumer neither has a disadvantage nor an advantage regarding the bank's yield on the KfW loan, because the conditions at KfW are always the same. What interests me is the result I achieve with the consumer and the bank's yield on the KfW loan has no influence on that result.
It is different with the mortgage conditions of the main bank; I definitely want to know that, because the condition I offer the customer is based on it.
I don’t understand the thing with 81% and subordination. Firstly, nothing goes beyond 81%, and secondly, nothing is needed after 81% if you want to use the "single out". Because the last cent from KfW is max 80%.
