Construction costs are currently skyrocketing

Real wages have been stagnating in Germany for nearly 20 years now. You cannot calculate with 2.5% repayment in 2010. Instead, calculate the monthly burden for the same repayment period; then it is comparable.

instead of teaching facial interpretation in school for years, it would be better to teach economic relationships and life.

I completely agree with you. I also think that society has become far too superficial and mainly cares about appearances. ;)

You can also take only 1% repayment with the 4.5%, then you have the identical rate as today, only the calculated term is a bit longer. To keep it simple, it would be the same. And whoever doesn’t have 10-20% more net income in 10 years of economic growth, sorry, generally doesn’t buy a house either.

So, with the same rate, you actually have more purchasing power!

The problem is that everyday life matters are not taught in any school. Taxes, finances, retirement provision, etc.... Instead, hours of Faust 1 or Wilhelm Tell are analyzed. Of course, that is part of it, but not to that extent...

House prices increased on average by 60% between 2010 and 2020.
Here is a simple calculation:

2010:
Interest 4.5% Repayment 2.5%
House price €400,000
Results in a monthly rate of €2,333

2020:
Interest 1% and repayment 2.5%
House price €640,000 (€400,000 x 1.6)
Results in a monthly rate of €1,866

Conclusion: the price is indeed higher, but it costs you less monthly, plus you have at least 20-25% more salary in total after 10 years.
Your purchasing power is significantly better and the rate makes up a smaller percentage monthly than in 2010

For completeness:
2010:
Total costs €640,000
Duration 22.9 years

(if you want to pay it off in 34 years as well, it looks as follows)
Total costs €781,000
Duration 34 years
Rate €1,920

2020:
Total costs with interest €756,000
Duration 34.4 years

You can also take only 1% repayment with the 4.5%, then you have the identical rate as today, only the calculated term is a bit longer.. To keep it simple, it would be the same then. And if after 10 years of economic growth you don’t have 10-20% more net, sorry, then you generally don’t buy a house either. Thus, with the same rate, you actually have more purchasing power! The problem is that in no school are everyday life matters taught. Taxes, finances, retirement provision, etc.... Instead, hours of Faust 1 or Wilhelm Tell are analyzed. Sure, that’s part of it, but not to that extent...

In the Bavarian curriculum, money, taxes, and retirement provision are included, but I don’t know how it looks in other federal states. Also, I had to laugh quite a bit at the "extreme" price increase in the documentary. In Munich, prices rose by 150% in the last 10 years, and with that the rate just doesn’t stay the same. As someone said in the documentary, you have to look at the monthly burden, and if a doctor can’t afford a 2000€ rate when both spouses work, then I don’t know. Still, the high absolute loan amount just shocks you, I can’t exclude myself from that.

It is clear that it scares some people when I see how many still convert into DM :D What’s the point? The hope that the DM will come back and everything will get cheaper?

Munich is of course an extreme.
Hamburg was also included in the 60% etc.

The doctor with 3 children ultimately bought for 750k. The problem is that many are overwhelmed by the large numbers instead of looking at the monthly burden. Many also think they have a burden, but you can sell a property in old age as needs change. And when I see that people then look for 200 sqm plus of living space, that has nothing to do with the average anymore....

But that is not the topic here.

The topic here was raw material prices and that can be confirmed. The first prefab house builders are raising their prices as of 1.5. due to the increased prices of wood and raw materials...
