I am stunned that there are such emergencies. That is really awful. But you don’t have to do that, there are other options!
Our example: We moved away from NRW and live with our children (5 and 3) in beautiful Schleswig-Holstein. Corona-free and with a high recreational value: Hamburg right on the doorstep, North and Baltic Sea each half an hour away. We live in a small, pretty Art Nouveau villa in the middle of the city in the best residential area. 180 sqm, 510 sqm with cellar and garage.
The place cost 345 TEUR in 2014. Since then, another 300 TEUR has been spent on conversions and renovations. An old house constantly needs care, plus we like to change and optimize things.
My wife works only 14 hours because of the children, our income is still good. In 12 years we paid off the loan. Still enough remains for saving and a good life.
Conclusion: in your place I would move away and start my existence anew somewhere else. And with your good income I would simply enjoy my life…
