House financing KfW 300 & 124 - please provide an assessment

Sometimes it is also about keeping the monthly burden lower in the initial phase. The KfW300, for example, has 5 years of repayment-free period. If you had to cover the amount over the main loan, including repayment, it often looks bad and no bank would finance the entire project.

But is the professional!

The KfW300, for example, has 5 years repayment-free.

And must then be repaid in the "last" 20 years with a term of 25 years, which leads to a repayment rate of over 4%. That can really hurt the wallet.

If you had to cover the amount through the main loan, including repayment, it often looks bad and the entire project would not be financed by any bank.

There, as a young family, you would have the chance to work with 1-2% repayment, have a lower loan (because you can then build according to the Building Energy Act) and have a more relaxed life. You always have to look at and calculate the individual case.

Sorry, but the household income is far too low for a new build, whether 90, 100, or 120m2. Apart from that, it would be at least a 105% financing, which (as far as I know) no bank currently agrees to anyway.

I have a bit more income and have financed a bit more and can tell you that it is only possible if you bring a lot of own effort into the financing. We have about €45,000 in labor costs as own effort. The downside is that you invest a lot of time in the construction.

I have a question about the KfW topic:
- Are you taking advantage of the subsidy because you want to build energy-efficiently anyway, want to install a controlled residential ventilation system, etc., or
- Do you want to build to the KfW standard because you hope to save money with the KfW loan.

both; energy-efficient house + savings with the KfW loan

both; energy-efficient house + savings with the KfW loan

KfW 40 is somewhat more efficient than KfW 55. With the wrong occupants or "optimistically calculated," it can also be worse. But it is more expensive. You have to calculate whether the KfW loan is really that worthwhile. Inefficient houses no longer exist today.
