Most big European cities have huge rents as well but no Bay Area salaries to make up for it.
Either apartments outside of Paris are dirt cheap or minimum wage in France is really high.
A dev from Paris I met in Germany said he left due to how unaffordable housing was so something doesn't add up.
Depending on what you want though, it can indeed be very expensive - e.g. if you want an apartment in the city to profit from the night life ( after 1am the transport to the suburbs is only with buses and much slower), it is going to be very expensive to buy.
And that's just for "regular" people. Each city in France is required to have a minimum percentage of social housing, to which you can have access ( including to buy) if you're below a certain threshold of income ( so on minimum wage, you're there).
Though I'm a bit skeptical as 200k is enough for a house in Eastern Europe on the outskirts of Bucharest, but in Austria where I am now and average house outside of Vienna is way over 600K so the Paris suburbs you describe seem suspiciously cheap to me at only 200k since Paris is more expensive than Vienna.
What's the catch?
suburbs with massive ethnic populations (1st/2nd generation or immigrants) are dirt cheap but for some of them that means getting food at the hallal butcher,eating kebab, going to a hairdresser where the windows are closed so that you can't see women inside, high crime, dirty cities ran by leftist at best, communist at worst that deny high income to move in those cities (because high income votes right) which spiral into more crime and more diversity stomping away what makes france france.
Airbnb + rich tourists wanting a flat in paris also destroyed real estate in paris (which is a small city)
Oh and before the downvotes im a 2nd generation immigrant.
From what I can find, minimum wage is around €1500/m, before taxes.
To be fair, that is a Kitchen to a great number of people on this planet.
I shared a mini fridge, tiny sink, and a hot plate with 2 other roommates when I lived in Paris for a few months and the rent was not cheap their either.
Was about 2,000 Euros/mo 15 years ago iirc.
