ive spent last 13 years going backwards and forwards to the alps. nearly bought an apartment, wish i had.
we always rent in uk and alps. 6 months each. its an enormous pain in the ass but my money isnt tied up in property
what puts me off buying is the paperwork etc in france is worse than uk and even worse in switzerland
you need to be very confident in the language or have trustworthy contacts
best to build good contacts where you want to buy and live there before hand
chalets are stupid money even in the valleys. you get the odd one that needs work but again you need local contacts to find these
i lived in les gets for a few summers but wouldnt want to go there now, its totally different from 10 years ago and its not the same as being there for a week
