The 50-year mortgage is crazy, we agree, 15 or 20 years at the most is the most financially sound, because as the article explains, you spend the first years paying interest and not amortizing at all. The longer the term of the mortgage, the longer it gets.
But I don't think this is widespread in Europe. I have no news. The maximum is 40 years depending on age and after the 2008 crisis the banks learned their lesson and no longer give you 100% mortgages. So if you sign a mortgage of 200.000€ you have to put down at least 20.000€, depending on the bank and your situation. Some will ask you for €30,000 or €40,000, so you are already starting with equity and even if you amortize little at the beginning, you are adding equity.
If I can believe that there will be a crash, I think it will be due to the general economic situation. If due to inflation people consume less, companies start to have problems and lay off workers, obviously people will have less money or access to credit to buy a house, and some of those who pay mortgages will not be able to meet their payments.
In pursuit to destabilize Russia - all those countries are in deep trouble now - winter is already there - and now they will be in more trouble due to less oil and gas supply. To me they have made very bad decision
