Malenka, hang on in there. You're doing well.
1) Ask them not to contact you by phone. Keep everything in writing. It will serve you better to have a good paper trail.
2) Dont sign an interest only agreement if you cant realistically meet the repayments.
Continue to repay your "half" of the mortgage
3) It doesnt mean too much that the MARP process has come to an end without a
conclusion. It actually opens the door for you to seek a solution under the personal insolvency act
4) Dont give up your home easily. The courts will be lenient on people like you who have come out of the Celtic Tiger years on the down side.
5) Your next step is to try to engage with the bank through the new Personal Insolvency Act. In my view you should use this to put a proposal to the bank to write down the value of your mortgage to the value of the apartment. The bank will probably refuse this but it doesnt matter, your attempt to solve the problem will be on record.
6) If the Personal Insolvency Act doesnt work, the bank may eventually try to repossess the apartment and you will get a day in court. In court you will be able to show that you are paying as much as possible, you will be able to show that you have made several honest attempts to solve the problem and I think you still will have a good chance, even at that stage, of keeping your home.
I hope it goes well.
