Building a house with 300,000€ is possible

I think you can apply this to almost any boom region or city with influx and a positive outlook. We also observed this nicely in Cologne. There is nothing, and when something does come on the market that is somewhat lucrative, it doesn’t take 24 hours and the plot is gone or immediately marketed together with a house. And areas where the price initially sounds interesting, you really don’t want to go there or even bury your dog.
In Hürth, the direct city outskirts, nothing new is being built, and if a plot was offered from existing stock, it was usually auctioned. We once looked at it for fun up to 600 euros/sqm.

After that, you can nicely strategize: the farther out, the cheaper it gets. Noticeably cheaper from the point you need more than 30 minutes by car to Cologne or where you can no longer really speak of public transport to Cologne (1 train per hour that also takes about 1 hour to Cologne).

I don’t understand why some people assume that everyone necessarily wants to move to a city? Many people can live very well without noise, traffic jams, exhaust fumes, etc....

Few without work. Be happy.

Who says you have to live in the city to have a job? I prefer to drive half an hour to work and live more quietly. I also worked for a time in Munich but lived in Oberschleißheim. The colleagues who lived directly in Munich often took longer with the S-Bahn and the few hundred meters on foot plus waiting time than I did. It’s the same now; I need under 15 minutes to get to the city limits, at least 15 minutes for the part inside the city to the company, during rush hour gladly 30 minutes, in extreme cases even longer. In other words, it would only benefit me very little to live on the edge of the city, but it would be much more expensive and not nearly as idyllic as in a town of 15,000 inhabitants directly on the forest border. And there I have all kinds of supermarkets, doctors, schools, daycare, train, bus, etc. I can understand at 18 that one might want to go out almost every evening, but at that age people usually don’t build a house.

Who, for example? Nowadays, you can draw a 20 km radius around any larger city, and within that you have the same conditions. We are also moving out into the countryside, but are still 30 minutes by car or train from the center.

I’d rather drive half an hour by car

That should be enough for a 10-page discussion, right? *getting popcorn*
