Expensive plot + single-family house 155 sqm + cellar KFW40+, financeable?

Are the real estate crises already forgotten? To ensure that no castles in the air are built on assumptions about how much money the house might be worth someday, or how much money might possibly be earned, it has been legally regulated that lending must be based on facts, not on statistical assumptions.

It is one perspective. The other: costs are rising. Wood costs more, the IG Bau is negotiating for higher salaries, etc. This potentially makes new construction more expensive in a year. Of course, the salary increase probably compensates for that. Anyway, that’s what a BU says. I would of course say the same if I wanted to sell something.

And exactly for that reason, if I were you, I wouldn’t let myself be influenced by the negative opinions here. Who else, if not you, as trained doctors, can absolutely build a new house in Germany worry-free for over 600k? If I were in your position, I wouldn’t even have asked here, because with less than 100k in equity, you can unfortunately only expect such responses in this forum. Apparently, no one here has considered that medical studies can be long and expensive. And not everyone has parents who shove six-figure amounts at them without expecting anything in return. And no, the house does not necessarily have to be fully paid off after 20 years. Sometimes I really wonder what some people’s ideas are here. If everything goes at least somewhat normally, the two will have a net income of 8-10k in a few years. Basically, there is clearly much more room than the sum being discussed here.

It is actually quite astonishing how well the rather "related" insurance industry knows probabilities.

Both industries master probability calculations. Risk assessment is significantly more regulated in insurance than in banking. Overall, the industries are regulated very differently. Insurance consists of IT, mathematics, mutual trust, and sales Bank consists of IT, imagination, one-sided trust, and sales

Sometimes I really wonder what some people here imagine.

The expectations that every customer is told in the daily mortgage business. Here in the forum, I have no other statements (even though I personally only accompany larger projects and leave the "small stuff" to colleagues).

If everything goes at least somewhat normally,

And if not? Suddenly unplanned twins arrive, accident with long-term incapacity to work, etc. That’s why you can certainly plan that for yourself, but you must not complain if outsiders do not rely on a "what if."

Who else, if not you, as trained medical doctors, can absolutely build a new house for over 600k in Germany without worries?

Everyone here shares that opinion without exception. Only the timing is (for banks) exactly the wrong one.

That a medical degree can be long and expensive, apparently no one has thought of that here yet.

To be honest, nobody cares when it comes to financing. It is totally irrelevant for a concrete inquiry. Unfortunately the problem of many academics.

To ensure that no castles in the air are built on assumptions about how much the house might be worth someday, or how much money might be earned, it was legally regulated that lending must be based on facts, not on statistical assumptions.

Precisely for that reason, the "fact" that a couple without children is looking for financing for a single-family house with two children's rooms should lead to exclusion. The same couple should be able to get financing for the equally expensive loft apartment without problems.

We can't change it anyway, and every industry is the way it is. But when I see that in truly safety-critical industries (aircraft construction / power plant construction) work is constantly done with probabilities and statistical (un)safety factors, I find the refusal of these in banking quite interesting. The banking crisis certainly did not come from the application of default probabilities, but from a too lax application of them, or from risk criteria that were too low.
If I build an airplane/house/power plant with a safety factor of 2 and one with 0.5, I also know that one will collapse/crash and the other will not. But the use of the factor is not to blame for the crash, but the value applied.

A different matter: why do you two doctors earn "only" €6200 (from 2022) together? Does one of you work part-time? Or do you not do on-call shifts or something like that?
