With all due respect. Just compare what you have to pay over 20 years if only 1(!) parent needs inpatient care...
My wife and I have 4... that can't be financed with 2 full-time jobs...
I don't know what you're trying to tell me. It was about finding an age-appropriate place to live for oneself.
Inpatient care is a completely different issue. That’s exactly why you build up retirement provisions in the form of a house, so you can use it yourself for dignified care. You have to take care of that yourself and not shift it onto your children.
Otherwise, various legal regulations come into effect regarding when children are obligated to support their parents. As far as I know, this is only from a gross income of €100,000 and not directly for parents-in-law (only indirectly). But that's drifting too far off topic now.
