Is buying a house sensible in the current market situation?!

... and even more than the interest, you pay rent to the landlord. Money is practically given away for free. Rental living space is not. And it is also a fact that in old age homeowners are better off than tenants (though they have - necessary? - bought flexibility at a high price). Even if there is no increase in value, it does not matter. Because as a retiree you live in the worst case in a property that is worth nothing anymore, whereas for example friends still pay high rent. As a homeowner you can only win.

Yes, but a bit one-dimensional. Because as a tenant I of course have to invest my savings or find other potentials. If we only focus on profit, then as a tenant investing in an ETF with about an 8% return for 30 years I "win" (of course I don't have a house – homeownership is pure luxury)

Please don't get me wrong. I don't want to deepen this discussion here even in a house building forum.

Well, that's how people are. Money that a man or woman gets hold of is spent or excuses are found in between as to why the savings are being used (great vacation, motorhome, new furniture, car/motorcycle, etc.). Owning a home is forced savings. Exceptions exist, but they are rare.
