But with that income, it is negligent to advise building!
I am not sure whether it is worthwhile, considering the development of rents, for a family of four (perhaps five in the future) to live in an apartment and not finance a house instead. In addition, from my point of view, which could be wrong, an apartment for 2-3 children should be so large that it is already expensive now. In my experience, such large apartments are either expensive and then inhabited by older couples who feel disturbed by 2-3 children, or the apartments are located in a socially disadvantaged area where you would not want to see your children grow up. However, these are experiences from a city with 500,000 inhabitants; maybe it is different in the Allgäu.
