Can I move out

Thank you for your feedback, I needed to hear it.I have contacted my mortgage company and realtor to get their advice too, I now know what I must do.  My ex is not fighting me for the house because he knows he can't afford it. We both know that selling it is out of the question as houses are not moving here in michigan at all. We are looking at taking a huge hit if we short sale and I don't want any blemishes on my pristine credit history. I am going to fight! I will not lose my house and I will not allow this situation to mess up my future. I will keep you posted.

I agree with spaznskitz...your the primary and it's your credit at risk. Why not make him get out?  Restraining order, perhaps?

well you can move out, but you are still responsible for the mortgage ESPECIALLY being primary until the house is sold.

Since you were never married there is no legal ramification.

Would the short sale cause you to lose money?

The rental is an idea, so is letting him stay in the home with a roommate - but that still keeps you primarily responsible for the mortgage, what happens if they don't pay?

I get that you are frustrated living with him in the interim...BUT you are taking a huge risk leaving the home when you are the primary mortgage holder.
