Can we really afford this, and will the bank support it?

There are actually various statistics on this. For example, that the unemployment rate among academics is only about 1/3 to 1/2 of the general unemployment rate or a study showing that the new job for highly paid specialists is back within about 3-6 months. At least in our fields of finance, IT, compliance, reporting, and sales, I see that colleagues can't really choose their jobs, but headhunters are still constantly calling. Or we commission the headhunters. They are even bringing back retirees with immoral offers.

Short update: This was also offered to us for €4,500/month cold rent. I laughed and declined.

Quick update:
We received a rejection from the seller for the sale with the reason that, after consulting their tax advisor, they decided to rent out the property. This was also offered to us for €4,500 cold per month. I declined laughingly.

I can understand the reasons for the termination (including tax liability) of the sales process, even if it annoys us since we had already invested a lot of time in the process.

We are now looking further without pressure or compulsion.
