I tend to agree more with Steffen. I studied, my wife completed a paid (so chargeable!) training. But somehow we both always knew that we would rather have a house someday, otherwise we were not party animals/money wasters (we "lived," but you don't have to throw money away in pubs for that). I have always worked as well and was able to save something even with a student mini apartment and a Golf2 (which was actually very repair-cost-friendly), although not much. At least there were higher interest rates back then, and over the years that did make a difference. After graduation and at work, we continued to "keep a low profile" (appropriate apartment 68sqm and, for example, no new car) so that at the start of construction 2.5 years ago we had about 50% equity at age 31 (for that we didn't build as expensively as Steffen). Some people think or say we have a high loan/bad conditions, but that didn't have to be the case. Rather, we wouldn't have wanted to build more expensively anyway, because of family planning/location choice.
