I tried to move to Germany recently, only gave up because family in UK needed help with parent with Alzheimer’s.

As an EU citizens, I have a right to go there and work. Work requires a tax code. Tax code requires a permanent address in Germany. Most places you can live require a job and good credit history.

I could bootstrap that by buying a place in Germany, and I might still do that if I am confident I understand foreclosure auctions well enough, but it’s amazing what a little creative bureaucracy can do to slow things down.
