If I'm reading this right, it seems the situation has little to do with the status of the house, and more to do with you wanting to move to an entirely different area while she wants to stay. Every time I've ever seen this situation in advice columns, the advice giver always suggests discussing your goals together, and seeing to what extent you can accomplish both your goals as much as possible. The key is to focus on actual goals, and not getting stuck in a position. For example, "I want to earn more money" or "I want to be able to see my family" are legitimate goals, while "I want to stay here" is not -- that's just restating a position.
Once you've laid out and understood each other's goals, then you search for options on reaching them. If a move is the only way to accomplish one person's goals, then you look for ways to meet the other person's goals at the same time. For example, "Okay we'll move, but we'll stay within a 2-hour drive or plane ride away from family, and we'll come back at least 4 times a year to visit them." Or, "We'll move for 3 years to advance your career, then we'll come back to advance mine (or see how things are going then and re-evaluate)."
If, for some reason, you cannot find a suitable compromise that meets both your goals, then you decide what's more important to you: Staying put because she's more important, or heading out because that is more important, and you don't want to stay with someone who can't or won't help you reach your goals. I think the way the conversations go will tell you a lot about where her motivations and reasons lie.
Good luck.
