I am not sure everything else is reasonable if groceries alone have been going up by as much as 100% throughout the world, heh. Maybe on an SWE salary it is reasonable, sure.
But after some research it is indeed true that house prices are, to a lesser extent, also going down, at least in real terms, if not nominal.
London house prices are falling quite a lot in real terms.
Have you ever considered adding more countries?
Its coming down but from a very high level in London.
I do not know about other countries, but movements do tend to be wide spread (at least across similar economies). We are seeing higher interest rates in a lot of countries and they are the main determinant of the multiple of income properties sell at.
