Do not be tempted to try to rent the property out. This will be a breach of the mortgage terms and will land you even deeper in the mire. You could, in any event, not really let it out with your ex still in occupation. A lodger, with one or the other of you still occupying, would be different as the property would still be owner-occupied.

The best advice for you is to go and see a solicitor and explain the full position to him/her. When you do so, you will need to discuss the prospects of either you or your ex becoming a sole owner and responsible for the whole of the mortgage [without you still, as you do at the moment, retaining full liability for the property but getting none of the benefit]. You will also need to discuss whether to apply to the court for a formal order for sale or some other, equitable, settlement.

You are young enough to bounce back from this. I hope that you do – and quickly! Good luck with it.

Grow some backbone. Tell HIM how it’s going to be! either he finds someone to pay the rest of the costs or right away get realtor to rent it out.

right now he lives way above his means and YOU are paying for it. He wanted OUT let him get OUT!!

Don’t pay one more cent for his LUXURY!

Siblings are much more likely to be with you in the long term than lovers.

If you can do that, that might be your answer.

You are paying your half and you ain’t living there and the same would be if you were living there and your ex moved out (paying his half and not living there).
