No matter, you will never always agree, it is all much too individual.
In the further course you write "We all agree that..." and personally I have to directly contradict you on almost all points
I mean, we all agree that buying something that costs for example 500,000EURO and is financed over 30 years always carries a risk?
The risk is not determined by the purchase price, for me risk is solely the resaleability, in case a catastrophe happens. 500,000€ in the middle of nowhere might be unsellable, in Munich a risk-free bargain. Other risks depend e.g. on the job, but not on the value of the property.
We all also agree that in principle or for most here in the forum, living in a house, if you can afford it, is more fun than living in a 2-room apartment under the roof?
An unfair comparison. How about a 2-room rented apartment vs 2-room owner-occupied apartment? There are also people who don’t want or need a garden. I have a self-made millionaire in the family who lives exactly like that in a rented place.
Because, installment 1650EUR, reserve 150, 1 car 500 all-in, additional costs 200, insurances 200, retirement provision 300, food 1000, hobby etc 200...
In this calculation nothing must simply go wrong. We all agree on that, right?
No, because we will never agree on any numbers regarding household management. An example: Our car is 250 all-in and we shop cheaper in addition. And suddenly there are 500 euros more available for a property. Oh here one can argue very very long without agreement.
If at the end of the month all running costs are paid and you have 50EUR left, then you CAN buy the house. But probably nobody here in the forum would recommend it. Right?
Everything paid and then at least 500EUR left... Then in my opinion one can just start thinking realistically about a house. My opinion.
First, one would have to agree on a basis of calculation as to what "at the end of the month" means. Are vacation and reserves already included? If yes, then you could even build with 1 euro surplus without problems. There are no major maintenance costs at the beginning, a new car is already fully included in your 500 all-in. So what could happen? I have NEVER spontaneously needed a 4-digit sum anywhere in my life.
Many people are simply willing to take this risk.
Here I fully agree with you
