You are not being robbed the bank look like they are correct. The reason the amount left outstanding plus interest is greater than your mortgage is you owe interest on the €420,000 you borrowed from them 6 months ago. The mortgage payments you have made so far have meerly been eating away at the interest owed.
To make matters worse AIB have now sent me a letter completely ignoring my written instructions!!! Arrgghh. Can someone please help with my original queries in the above posts. thanks.
