I don't see a problem based on the current numbers. It gets tight if there are 3 years of study ahead, you are not married, and then she wants to start a new job and after half a year/a year the kids come right away. Then you can basically only count on about 4,800 euros, and the loan with 2k plus 400 ancillary costs is already 50% of your household income, and that for a few years at first because you don't go full-time again right away. Challenging, but doable. In your place, I would definitely 1) get married beforehand or make the appropriate contract 2) either study or buy a house, my opinion 3) wait for the study to finish, keep saving diligently, and postpone the decision until after the study when it is clear where and how and what she works
