Ok to clarify-
It would all be done legally. She would "buy me out" - I would have nothing to do with it anymore. Profits in 5 or 10 years would have nothing to do with me.
I am not sure how the whole buying out thing works, hence the post!
She said that she saw a financial advisor recently and was told that she would be able to do it - she's on good money etc;
I definitely do not want to buy her out. I am willing to walk away. If all of this is possible.
I think the chance to get away from the negative equity is something I can't afford to pass up on. This apt is half an hour from the city. Not great re; Public Transport, I don't think it will ever sell.
