Brief info from a prefab house manufacturer. They themselves are currently having problems obtaining wood and other materials. Wood prices have risen by 50-100% at the moment and other building materials by 20-50%. Therefore, they will have to adjust their prices as of 1.5, which others will probably do as well....
The report on NDR is quite funny but only shows one side. You would have to show the wage development over the last 10 years alongside it and what effect interest rates have on the burden as a comparison.
House prices increased on average by 60% between 2010-2020. 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 and you will have at least 20-25% more salary overall in 10 years. Your purchasing power is significantly better and the rate constitutes a smaller percentage monthly than it did in 2010.
Such things are unfortunately not shown or the people are not informed. Then it’s just about the evil investors or speculators or whatever....
Instead of teaching facial interpretation in school for years, it would be better to teach economic contexts and life.
