Is a single-family house in the Stuttgart metropolitan area still affordable?

On the other hand, we both earn over 100k with significant potential for increase, so the little house is possible. Even without a charitable loan from the parents. And by the way, also clearly far from any allowances to avoid having to pay for the care of the parents...

Yes.
Addition:
With us, this is constantly changing right now because of the children. First parental allowance, then nothing more for me, now re-entering the workforce.
But we both have employment contracts that definitely pay six-figure salaries full-time. In addition, we both have large amounts that are paid variably based on performance, so our income is not so easy to determine.

Also, we have even more luxury; we don’t have to work full-time for our 6k and can spend a lot of time with our children.
So we are very satisfied

And what I also found interesting overall in your thread.
I also often thought, who can afford that...
But compared to you: We pay a total volume of 1 million with comparable income. And we have not inherited anything so far. So there is still a lot of room above your price expectation.

It has nothing to do with contradicting, it's just that things are very variable for us, that's true. While in August we lived on one part-time salary of my husband, now we live on two part-time salaries. And from January, my husband will probably work full-time again due to a managerial position. The bonus payments this year amount to approximately 30k-40k just for my husband, from now on something similar applies to me. Of course, contradictions arise due to so many influencing factors. And those are not even all the influencing factors.

And I still haven't inherited or been given anything, but a loan on which we even pay interest and which has a fixed regulation on when it has to be repaid. That is not the same as a gift because we have to consider it as debt capital in our personal financial planning. It could be demanded back at any time with a notice period of 3 months, even if the case is very unlikely.

By the way, I am now withdrawing from this forum since our house construction is finished and I see no reason to voluntarily make myself upset. We are doing great, we both completed two degree programs with top grades, both have PhDs, healthy children, great parents, and are very happy as it is. I am not accountable to anyone for anything.
