Construction costs are currently skyrocketing

Aha, and what is senior-friendly? Any apartment with an elevator? Or even something with care? That is insanely expensive! Compare the prices of a 30-year-old house to fancy rental apartments or condominiums. But nice that you already included the subjunctive. I would bet that, like everyone else, you don’t want to move out when you’re old :D

With all due respect. Just compare what you have to pay for 20 years if only 1(!) parent needs inpatient care... My wife and I have 4... that is not affordable with 2 full-time jobs...

If it weren't so sad, it would be funny... Sending parents to Greece because it's cheaper...

You misunderstand me - I am not sending. I told my parents that they should live.

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.

So my grandparents each found good solutions for themselves. Some sold their house cheaply with a lifelong right of residence in the existing [Einliegerwohnung], so no more house stress but also no moving out. The others sold their house and moved into an age-appropriate apartment with optionally rentable care, so optional assisted living, which they have not used so far (my grandpa is over 80). Both are happy with it.

Yes, but why only? I also told my parents: Sell the house and do whatever you want – go to Greece or something. They didn’t – typical German: healthcare, language, etc. etc.

They have all the options – but they’d rather be scared and get upset.

That’s understandable too. Do you want to live in a country where you can’t even talk to the neighbors, the baker, etc.?

Do you want to give up your friendships here in old age and live there without friends? Making new friends at 80 is difficult.

Do you want to see your children and grandchildren only every few years?

My girlfriend's coworker is also currently building, and this week the screed is supposed to be laid, statement now: no more heat pumps this year. It is a group that calls itself like the core of an apple. There are always some, but wholesalers want 50-80% more than the normal price, which is why the company says we are waiting, some are supposed to come in February.
