Financing land and house construction

Why not, the cabin doesn't have to grow linearly with the plot size

I'm not quite sure what is meant by that.

It's not just about the cabin. You can get a cabin for a thousand euros. This is about pages of how a high rate is accepted and sugarcoated by saying that he can save 1200€ monthly on the side so that he can make great special repayments in 10 years. That can work if everything is well calculated. But it isn't here.

A lot is being given away with plants at the moment, partly entire hedges,

Yes, you can do that besides having 3 kids and gather everything together. The kids aren't even old enough to help. For some, that's a hobby. I somehow don't see that here. However, there is also the risk of getting burdock and co for free (happened to me in the old house – I never got rid of it again as a working person with other commitments from the garden) A bamboo, in which ivy and a rose have spread in the root ball, also brings a lot of joy. But as already said: it's not about details – it's about everything being calculated very tightly and planned. Being disciplined to deny yourself and not buy anything is different from dreaming of automated cars and implementing smart homes.

Yes, you may be right. But what is the alternative? Taking on a higher rate that has to be repaid and costs interest? Not building because you simply cannot afford the 30,000 euro kitchen and the great fence right away? Everyone has to decide for themselves, but I would (and have) always made some concessions first in order to even have the possibility to live in my own house.

After the final loan approval, I wanted to give a concluding update here as well. We have now secured the following financing: (1) Commerzbank, €581,000, 15 years, 3.27% (2) KFW 300, €200,000, 10 years, 0.66% with 5 years interest-only (3) IFB, €150,000, 15 years, 2% with 1 year interest-only We are super happy with this overall package and very curious about what will come our way during the construction phase :-)

May I ask how high your monthly loan installment is and how high your repayment is? What remains after 30 years according to the payment plan?

May I ask how high your monthly loan installment is and how high your repayment is? What remains after the payment plan after 30 years?

Our monthly installment is €3,375 with different repayments depending on the loan component (1.26%, 2.55%, 3.02%). The remaining debt after 30 years is difficult to quantify due to the various components and many variables; roughly estimated, however, €300k according to the payment plan; in reality hopefully +/- 0 (our personal goal).

Then the cabin simply isn’t fully paid off after 30 years according to calculations, but that’s not the end of the world. Enough has flowed into the repayment by then, building a solid asset base.

What really matters is how much interest is paid. That’s not even 2k per month in total, and that’s at the starting point (interest portion decreases, as is known). You could pay that anytime as rent in a big city (probably more with 3 children). Thanks to the promotional loans, the interest rates are well below inflation (and will likely remain so in the future, or does anyone here believe in a permanent return well below 2%?). Therefore, I would repay as little as possible but simultaneously invest the money (initially more in daily money hopping at just under 4% due to liquidity reasons, and with increasing liquidity reserves then more profitably in stocks).

The risk lies in the health condition and earning potential of the sole earner. That’s a psychological pressure you have to cope with. That’s why it’s better to start saving equity early in parallel so you can balance out dry spells. Living frugally to start with is certainly not wrong.
