Hello everyone :)
I sincerely thank you all for your input. Regarding finances, that is indeed rather secondary and should be less the subject of discussion, even though it is of course an important point. Because logically, we would love to be able to estimate exactly what is coming our way.
Bauherren2014, equity is practically zero, it is only about 10,000€, so there is probably no prize to be won there, of that we are fully aware. And also the various construction financing partners we have spoken with all consider a monthly rate of 1,300€ definitely feasible. Status NOW. That does not change the fact that I am, as you so nicely put it, a scaredy-cat ;) Surely the income of my boyfriend and mine will increase exponentially, and accordingly that should definitely be manageable. But it also needs to be weighed: invest more and get a bigger house/plot or make compromises and spend less. Ultimately, one must also simply consider that a large plot and a big house need to be maintained and kept in good condition.
Construction expert, for 188,000€ we would get 133m², triple-glazed windows, an air/water heat pump, a walk-in shower, double washbasin, closed stairs and a suspended ceiling from the upper floor to the attic so that the attic can still be partially used as a room.
This offer may possibly become irrelevant to us, because as chance would have it, yesterday we received mail from the city [I.], that the application process for a new residential development is starting. We will definitely try our luck. The m² should cost 92€ including all development costs and solar bonus. The favorite plot is therefore priced at about 58,000€. The only drawback: single-story construction is mandatory, roof pitch minimum 15°, maximum 50°, the knee wall may be a maximum of 1.50m in height. Now, I am quite a layperson, but if the knee wall may be 1.50m high, then the house will at least "appear" afterwards as if it were two full stories, right, or am I completely off the mark? Because a bungalow is definitely out of the question for us.
The idea of having our dream house freely designed by an architect appeals to us more and more. Nevertheless, we would have to basically award all contracts through tenders, since talent on our part is, as mentioned, unfortunately scarce.
And in the very worst case, the scenario proposed on the previous page will come into effect: wait and save ;)
