Single-family house financing €950,000; loan amount €750,000, equity €200,000

But I doubt that anywhere within a 50km radius of Munich it is possible to build a 150m2 house (especially not with a basement) on 700m2 with NBK, double garage, and outdoor facilities for significantly less than €950k.

That's what I am saying. My point exactly. Because you can get even less a 2017 house for that money. Even a divorce house doesn't have to sell so far below price.

And you can also study in Germany (still) without rich parents.

Yep.
Nowadays, a student can get a student loan completely easily and all on their own (without mom and dad) (not BAFÖG), which parents would never get due to lack of collateral. Many don’t know this or don’t have to know it, because mom + dad already handle it themselves plus often the trendy apartment as a bonus.
Thus, every student (who is by the way an adult!!) can invest in their own future, later get a better-paid job on the job market, and pay back their previous future investment (student loan) quite leisurely. Perfect – that doesn’t exist in many countries!
In my opinion, this is a great and additionally healthy measure for young people, which is often sabotaged by parents themselves, while at the same time they like to complain about the high costs of their studying children. That is self-made and luxury that apparently people just like to afford!
When I talk to parents about this great option of the student loan, they just brush it off... we prefer to do it the way we have been so far... (and keep complaining)!
In Germany, ANYONE can study, even if they are a full orphan. Nobody has probably ever said that it’s given away here for free. There are probably reasons to be found more with parents why entrepreneurs and companies repeatedly complain about underperforming and phlegmatic applicants.

We were working instead.

Working.... despite studying?? Always these strange-sounding words........ I find it hard to listen to some of the whining about later studying etc. It is already evident from this that parents nowadays like to interfere in the lives of their eternal children by deciding even before baptism that the good child will study. They don’t even consider anything else, that would probably be antisocial, for example an apprenticeship as a carpenter or training as a dental assistant. Nowadays, hardly anything less than a Nobel Prize is acceptable, while international comparisons and inquiries with employers say exactly the opposite. They talk about a youth that is often spoiled, performance-averse, with increased expectations. The problem is not the children......nor those who want Nike etc. They only want it because they were brought up that way, while it is always gladly blamed on other children & families who supposedly exert this pressure.

Ho,... Then let him put the money into the master’s exam for vegan butchers for all I care. Or buy himself an ice cream truck. Seems more sensible to me than him buying three Weber photon grills from my estate at 50 and paving his flying car garage with Swarovski stones. Where here the importance of leaving something behind is often emphasized. :)

That's what I'm saying. My point. Because you can get even less for a 2017 house for this money. Even a divorce house doesn't have to sell so far below value.

Do we already know where the house is located? Depending on the equipment, you can easily build something like this without your own labor for about 750k including the land, even in the commuter belt of Munich.

Well, alongside studying. We both had medical training beforehand and could each work 24 hours per week. My husband at night and I on weekends. It all worked, but of course, things can be easier. It was okay. We are almost debt-free from our studies, we were even able to save.

But enough about this topic now, I just wanted to say that not everyone automatically receives support from wealthier parents.
