Hi there … for 2 homes in France… One of the homes must be designated as your Residence Principal…and all and every official document will come to this address. The other home then becomes Maison Secondaire.
When selling Residence Principal there is no capital gains on any profit… when selling Maison Secondaire… there is.
Taxe Foncière x 2
Taxe d’Habitation x 2 (if both houses are habitable)
2 x lots of standing charges for Water, Electricity, etc etc
2 x lots of Property and Contents Insurance
1 x TV licence (covers both homes)
and the rest depends on what you have…
This should give you a rough idea… others will chip in with more detail… or correct me if I am wrong…
