House planning completed - Is financing realistic?

You forgot: electricity will not cost 50 euros a month, but rather about three times that (with KfW55 technology). The building insurance is also often forgotten. Then the initial misconception read, KfW55 gives you 50,000 euros... that is not true. You can finance 50,000 through the KFW bank. But you were probably already informed about that.

This financing offer with repayment through the building savings loan sounds to me like a parody of the story Semmeling - once in a lifetime! For those who don't know it: please google it! A must-watch for all home builders.

And really... 1400 euros... we have 4000.00 a month, are unnoticeable, and I immediately feel sick at the thought of a 1000 euro repayment.

Could it be that you have overlooked the KfW loans? You have to service them for 5 years without any repayment, then you repay for 5 years, but roughly estimated after 10 years you will still have a remaining amount of 80,000. In addition to your bank loan. Well... maybe it will come to that... with the repayment... I don't feel like calculating anymore now.

Hello! - Electricity also comes from the photovoltaic system on our roof... primarily for own consumption, then for feeding into the grid. - I have always known that the KfW does not give me money for free and only offers a reduced interest rate, you probably misunderstand this when reading, maybe I was unclear in my phrasing. - The bill includes repayment after 5 years of exemption with the KfW, up to the 10th year. You estimate correctly, after 10 years there are still about 80' KfW loans left, but the expensive bank loans are almost gone. Furthermore: we neither drive a Porsche nor eat beef filet with truffles every day... after 5 years of keeping a household budget, the costs are effectively like that.

No problem, feel free to ask! So: The 3,xx% are secured through the [Bauspardarlehen] with which we will finance the majority of the follow-up loan after the 10-year fixed interest period from the bank+[KfW].

Hello from me too! Actually, there is basically nothing wrong with the financing, although it is already planned very tightly. Much more problematic, however, I find the money requirement for the house construction. 385,000 for 170 sqm living space? We are building 163 sqm living space for half the price, solidly built. Well, without a double garage, but I think you should reduce the costs a bit. Then the financing will also be much easier.

From all the good and less understandable answers, I’ll just derive my points.
bullet points ;)

- 385k euros seems quite generous for a wooden house of that size. Is there a lot of luxury in there?
by the way: we just built a solid house Kfw70, with high-quality tiles (alone 30k euros) and 162sqm on the two floors, 50sqm in the attic (which has a real staircase and no pull-out stuff) and 95sqm basement (white tank). The whole thing "turnkey," meaning walls and ceilings are my responsibility, the rest is finished. Cost including 500sqm plot 350k euros
- 50 euros for electricity is child's play, you can easily double that
- garbage collection usually costs more, depending on the region. Here we pay about 300 euros per year
- insurances? The building insurance alone costs me 30 euros per month. Household insurance not included, that comes extra
- property taxes: how do you come to such values? Either in the middle of nowhere, where the municipality still has money and no drastic rates, or confused by the first notice, as it only refers to the undeveloped land. Just as a figure: we pay around 1000 euros per year!

Then please also, very importantly, calculate correctly for the future!
When the house is paid off, it’s old... whether 25 or 30 years hardly matters... the fact is: major repairs will be due. Heating, roof, windows... you can always expect all that after 25 years. That will cost a lot of money, it must be saved now!
It’s certainly anything but fun as a retiree (who then hardly gets loans) to be confronted with 50k euros of renovation costs, which he doesn’t have :)

Although one also has to be a bit reassuring:
Whoever has 4000 euros net and is UNTERMINABLE (permanent), but still gets nervous at 1000 euros a month... I really wonder if I’m crazy or just not so anxious. If THAT were the general standard, only lifelong civil servants of the higher civil service career would own property and no one else.
It really doesn’t have to be that extreme! Many are always afraid of the “years-long loan burden,” but easily forget that rent is a lifelong burden.

We have 5k net, neither of us are civil servants, and pay 200 euros per month for the house (but repay quite a lot, so that’s why it’s that expensive)

I don’t feel bad and we manage just fine ;)
