Is financing for a new single-family house possible?

Yes, but we are basically a teenager who has already smelled freedom, you can't re-educate that so quickly. It will take another one or two generations until we are so sluggish that something like that is possible. After all, retirement at 67 is already in place, by the time I am 67 it will probably be retirement at 70.

It is interesting that such opinions as you have are usually expressed by people who already live in a single-family house. Just sell it and move onto your employer’s couch?

But that is totally on trend. First, you rake in a fortune in the "wrong life"... then you quit, buy a farmhouse with many animals... and then tell people that you now "live properly" and that everyone else should please also give up.
But your own cattle? Of course, you slaughter them. What else are you supposed to do with them? After all, you also want to eat steak sometimes... in the "right" life...
I believe Judith Rakers made a point about this this week... but Markus Lanz also jets around the world to then explain to us that we shouldn’t do that because it kills the polar bears... absurd.
Hannes Jaenicke also discovered in his mid-50s that you have to give up things... sure, he also had 55 years before that to fully enjoy life. And so on.

Where did I say that I support that?

Where did I say that I approve of that?

Sometimes I wonder what is wrong with you...

Actually pretty little, and you? Why are you getting personal again? Tell me, where did I write that I am in favor of only building multi-family houses? What you just did is like: Me: "Male lions eat the cubs of other male lions." You: "You can't be in favor of eating lion cubs!" Just because I describe it doesn't mean I think it's good and that we should do the same.

... is that what you're saying? ;) I think you always focus on individual statements someone makes and don't see the context in which the statements were made.
