I can share my own experiences from France. Buying an apartment is certainly possible, and there is experience with foreign buyers, partly because in France, a child can inherit 100k of real estate tax-free from their parent. In France, all apartments are considered real estate. Finland and France have a tax treaty, based on which a Finn who owns an apartment in France can transfer a 100k inheritance to their child tax-free (in theory; I have no experience with how the tax authorities actually view this, but at least this is stated on the tax authority’s website). If there are several children, the value of the apartment can be divided among them, meaning, for example, a 300k apartment goes to three children tax-free. Of course, this involves a fair bit of paperwork, a European Certificate of Succession, etc., so it requires patience from the heirs, and if someone in the family speaks French, the process becomes significantly easier.
In France, real estate agent fees are higher than in Finland, and many apartments are sold without an agent (de particulier Ă particulier). This high cost of agents is partly due to the fact that buying/selling an apartment is very bureaucratic, and notaries play a significant role. In France, a notary is like a junior lawyer who drafts the sales agreement and reviews it. In Finland, the seller/buyer themselves takes on a similar role.
When buying an apartment in France, it seems to be a fairly common practice to first make a purchase offer and a promise to buy, and only then process the paperwork through the bank; this takes 2-3 months.
Then, about living there itself. In French style, everything is done either efficiently or bureaucratically slowly. In my experience, at least in Southern France, housing association matters are often handled a bit carelessly, and renovations are only done when the condition of the building absolutely requires it. In Northern France, these matters are apparently handled more meticulously. In winter, apartments can be surprisingly cold; I recommend getting double-glazed windows.
But it is certainly pleasant to live there. These quirks can just surprise a Nordic person.
