Construction financing single-family house - What is possible, what do you advise?

So I think the incomes do not align with the construction project AND the desire to have children. Even if the first child does not arrive for another 5 years and your income then rises to ~3000€, it is hardly manageable on its own if the woman does not return to work immediately after parental leave. The planning will have to be adjusted significantly downwards.

If you already have the land, maybe you could have a soil survey done? I don't know who the right contact person would be, but then you could already get a rough estimate of the costs for the earthworks? This item seems to be hard to estimate at the moment. Then you would have an indication of whether the project would be financially feasible.

Thanks for the N

So I find the incomes don't match the construction project AND the desire to have children. Even if the first child arrives only in 5 years and your income has then risen to about €3000, it is hardly manageable alone if the woman does not return to work immediately after parental leave. The planning will need to be adjusted significantly downward.

On what points do you base this? In say two/three years we can go into the calculation with about €70k - €80k in equity. Which points do you find too expensive or unrealistic in the financing? Thanks in advance

I think the most pragmatic way is to go to a general contractor (GU), with whom you discuss everything, express your wishes, and create a rough space plan. He can also quickly give you a price, possibly minus your own contributions. Then you at least have a ballpark figure of which direction the whole thing is going. An architect would also be an option, but they often charge money for the basic evaluation (see also HOAI). After that, you should feed the common financial calculators with data and see what comes out. But take factors like children, parental leave, vacations, purchases (car), etc. into account. The usual recommendations are to use a maximum of one-third of your income for the installment, aim for a low loan-to-value ratio (<80%), and be finished before retirement.

The usual recommendations are to use a maximum of 1/3 of your income for the installment, keep the loan-to-value ratio as low as possible (<80%), and be finished before retirement.

Of course, we will take this route.
And it was more about gathering experience beforehand and gaining impressions about financing, etc. in advance.

Max. 1/3 of the income sounds relatively little to me now:
In our case, it would be about 1250€ at the beginning, and later the amount would of course be even lower.

Our expectations here were about 1200 - 1400 € monthly installment over the entire financing period, including special repayment agreements.

Then just practice setting aside the 1400€ now and see if it works out. But please over several months. Counting on special repayments... well, there are plenty of statistics that show that very few use them. I think once wrote something about this. I myself only made special repayments twice and only once with the full amount. Vacation, car... something always came up.

We will do that. Let's see if it works out that way. A friend who recently built recommended the special repayments to us. He uses them quite successfully.
