Thanks first of all for the answers. To clarify a few things:
First of all about the loan: The 350,000 includes ancillary construction costs, land, floor coverings, and other costs. So we really only need 150,000 euros.
2,400 euros is pure net income, health insurance is already paid from that. Besides, we currently have no liabilities, the car is owned, we live rent-free. So the equity is even increasing at the moment.
Regarding the pharmacy sector: It is the case that many university graduates initially work on a so-called substitute basis, as it is significantly more profitable than being permanently employed. My husband could earn almost twice as much if he worked full-time. He could also be permanently employed. But he doesn’t necessarily want that. Otherwise, we have rather modest demands.
It is very unlikely that the order situation will change. Above-tariff pay is standard, study places are capped, pharmacist presence is legally mandatory. There is a severe lack of workforce.
Regarding the 5 people my father is supposed to support: As written by a forum member, in this calculation my husband’s salary is not recognized, as he has not been self-employed long enough. Only my father’s salary is considered secure.
I think we will get back in touch with some banks (and possibly also return to Epis’ offer: Thanks!). Otherwise, there is always the option for my husband to become permanently employed. Unfortunately, the banks of course also want to see the probationary period completed then.
