Sounds like a near perfect existence. I'd stick it out another two years. You really already have everything you need/want.
As for moving after reaching FIRE... I'd tread cautiously. You are close to family, and family nearby is something I value tremendously. Also, if/when you have kid(s), family becomes even more important (one, for support, but also, two for having the child connected to their relatives).
However, it does sound like you are itching for a change. I'd say, reach FIRE, then plan an awesome traveling adventure.
