Can't speak for Europe overall, but in Germany it's highly uncommon to buy a home until you've either finished studying and have a proper job, or in the case of vocational training, having worked a few years. We seem to be pretty averse to debt in general, so for most people "buying a home" is the only acceptable thing to take on a large debt, and even you're probably already 30-40. Of course this is a little different if you live where housing is really cheap, but good luck getting an apartment or a house for under 500k-1m € in a big city.
