This is so alien to me. Why don’t you sell the place? Staying the owner of this place makes it so that you can’t spend your money tied up in this house, and this house can’t provide its roof to someone. Seems like both of you loose.
Selling might trigger a very large tax liability, depending on original cost vs. current price. When that is the case, it's better to keep it in case you might want to return to the area in the future.
