Thank you very much for your initial responses.
Regarding one specific question: An owner-occupied apartment is not an option for me because I find the price/performance ratio unreasonable here and I want to remain financially flexible. If I have something that needs repair soon, for example, I want to decide myself when to do it and not be forced into anything by the majority of co-owners.
Moreover, an apartment does not offer me an enhanced quality of life, because I really need my desired garden. And in my opinion, an apartment with a garden is absolutely unrealistic in this price segment. What is asked for apartments here might be acceptable from a market perspective, but what you get for your money does not reflect the value for me.
The feel-good factor in a house is simply greater for me. That is purely a matter of taste, but I would never want to invest that much money for an owner-occupied apartment for my own use.
Regarding the salary: I also assume significant jumps are to be expected here. I noticed this when I switched from my very first position (in-house) to consulting. That was suddenly 14k more. With an employer change, I got even more, with the option that this salary will be renegotiated after the probation period. I think this is to somewhat reduce the investment in onboarding. Since I have been productive from the start, I see clear room here (probation period ends in 3 months). As a starting point, I will demand 15% more.
And then I expect another 4-5% per year.
I also think I am not at my limit, but that is the problem when you have no references and can only rely on salary portals with approximate average salaries.
In addition, I work in the area of digitization/BI, which stands out again due to the current situation. Keyword Industry 2.0.
Something should happen here soon. Otherwise, I will simply switch to the next larger consulting firm, because there is definitely no shortage of offers.
But that is not the topic of discussion here either. For now, I take away as a first point that I will save as much as possible in the daily allowance account. That was the prevailing opinion after all.
A building savings contract for 5 years is somehow not worthwhile in my opinion; I get nothing from it, and I only get the loan interest on the saved amount + loan sum on the building saving contract. And I will definitely need significantly more loan.
Thanks again for the previous responses. Of course, I remain open to more information/thoughts.
