Not sure if France is the same, but in Spain a temporary residence visa requires that you stay at least 180 days, or you will not be able to renew it. This can be inconvenient and it also means that you'll become a tax resident there. You'll also always be liable for US taxes due to its citizen based taxation.
You are doing all the due diligence. There will still be surprises…there always are. But how exciting!!!
