Hah @Lilian20 should we mention a few?
Tax habitation
Tax foncière
Tax audiovisuelle
Tax professionelle
+ a small tourist tax to the town hall
That alone amounts to €2000 for a not so large holiday home. The bill from the coproprieté/syndic about the same. Income tax to Norway 25% + caretaker another €2000.
I am on the third washing machine, second dishwasher, second hoover, second drier, third fridge and second bbq in 12 years.
A very optimistic estimate will leave me 50% net, usually less.
On the plus side - we have a free holiday home for 6 months of the year.
