Hello @Emilie @Mudassir0
There are many, many things to put in place before renting legally in France and the "Anti Airbnb" law (yes, seriously they've named it like that😡) is going to be put in place early 2025 so there is much to consider.
It doesn't look like Mudassir is seeing the likes or the replies he's had so if you don't mind Emilie, I'll wait to see if Mudassir asks for any help before spending time and energy on this.
It's not clear if he is wanting to sublet the apartment or if he owns the apartment and it would be helpful if we knew if this is his main home or a secondary home that he is letting. (Different laws apply) There is no profil and no listing so not much to go on.
