KFW 153 - Repayment grants and maximum loan amounts increase

A waiver of the KfW commitment is possible through the credit-transmitting financing institution.
At the earliest six months after receipt of the waiver declaration by the KfW, a new application for the same project, that is, the identical investment object and the identical KfW efficiency house level, can be submitted ("blocking period"). The then current product conditions apply to the new application, including the regulations on the start of the project.

The information sheet says the following: I therefore assume that you would have to wait 6 months if you already have an official commitment from the KfW. Only the KfW can probably tell you more precisely.

[*]for still undrawn loan amounts, if [*]the regulations regarding the start of the project are still being followed (compare question: When can I begin construction work?).

Please explain to your financing partner a waiver of the still undrawn KfW subsidy and submit a complete new application (including a new "confirmation of application (BZA)") for the (other) KfW Efficiency House level. The new commitment is issued under the then current product terms and conditions (including interest rate and repayment subsidy amount).

That makes granny flats even more exciting.
