That's not a bad idea, I love the Okanagan, though it might be a bit isolating. Salary is certainly one thing, but I wouldn't move for salary alone or that of my partner (I don't think). There just isnt enough personal value to be gained in salary increases enough to sacrifice being with or where you love to be.
My end goal is to move to the Okanagan and get a remote job where I could get similar pay to Vancouver with much lower living costs.
