A counterpoint from France: media did report that for the first time in a very long time, home prices did slightly drop in Paris proper, while suburbs and "smaller cities" have seen a bigger rise than usual.

This means there must be more than just a handful of people leaving.

However, I do agree with GP's point about companies ending the WFH arrangements, especially given France's work culture. But then again, I've always found people around here to have a tendency of thinking fairly short-term.
