Does the real estate market increasingly force more families to build?

Minor repairs up to 100,- must also be carried out by the tenant themselves.

Well, then you have a "problem" anyway

Yes, thierse has to call the electrician when the light bulb is burnt out.....

The performance does not reflect wage development

But that has nothing to do with "extreme locations." I referred with this note to places where the "value" of a property is measured by the budget of the highest bidder. Such purchase cases will never be in any (reasonable) relation to general wage development.

This certainly also occurs outside the cities typically mentioned in such discussions, but it is probably not the norm there and instead relates to individual locations.
We also have a residential area here with land prices beyond 600€, but that does not mean anyone can sell their old building outside this district for 500k or more.

We have had this discussion several times. The middle class ranges from here to there and is not only represented by the median

That is correct. Nevertheless, it does not change the fact that someone with an income below the median usually cannot buy property because they have too little. The competition between private and commercial buyers is not entirely innocent here. The rest is taken care of by the lobby.

The fundamental problem is that many things in house construction are considered standard, which are actually luxuries. But: "You only build once." It is no wonder that houses are getting more and more expensive....

Compared to today's price levels, a shell construction built according to the 1995 energy saving ordinance would cost about half. The maintenance costs for heating would indeed be between 70 and 100% higher, but who cares when you put €50k and more against €600 per year? Ecological balance? Forget it! The decision-makers don't give a damn about that.

...Likewise, childcare outside the home in the city is better than in the countryside, where the woman and mother can rather stay at home because building a house is cheaper there...

I cannot confirm that. In our old home (just under 180,000 inhabitants), we would have had to fight for a daycare spot. In the sticks, it was not exactly thrown at us, but it was unproblematic to get one. It was also cheaper back then because, unlike the described big city, the municipality had no private daycare providers.

...The pearls on the market are 99% sold informally anyway. Without contacts, no chance...

One can only appeal to one's own initiative. Of course, those who focus only on search engines on the net and at most newspaper ads will not find anything that way. We used geoportals to find building gaps and then went there to see if it fit. After that, it was time to knock on neighbors' and owners' doors.

It is the same here - in the rural areas around our city there are enough daycare places. In some cases, even children from our city go to daycare in the rural municipalities because nothing is available in the city. A friend lives 50km away from us in the countryside (we already live on the outskirts of the city) and in her daycare, children who live in my city attend. However, I assume that the parents also work there somewhere or at least halfway.
