Mark12, you have made some very valid points on this thread.
Boomtobust, you can bet your last Euro that the bank will never agree to any proposal you you but fort to them within the next five years. Currently you are no more than a mere tenent of the bank. Once you are paying for the cost of the loan which is the interest, the bank are happy. You are also keeping their house/apartment safe from squatters moving in and generally maintaining its upkeep. I am also presuming you have insurance on the property and a life policy to booth. If so they generally wont come near you.
Now, if the Celtic Tiger raises its ugly head once again, then you have a problem - along with another few hundred thousand distressed mortgage holders around the country. Mr Banker will then want his keys back.
My own guess regarding were this is all going to lead is similar to what happened in 1988 when Dublin Corporation allowed tenents to purchase their homes at more than reasonable prices to the tenent.
I believe today mortgages are available to City Council tenents to purchase their homes at also reasonable costs. Funnily enough a neighbour of my sisters is purchasing her house via this mortgage scheme for €50k off the DCC. My sister currently has a mortgage of €275k on exactly the same type of property two doors down!
Getting back to my point, I believe that the banks are currently trying to sit this recession out and from their warm cosy offices believe that in another 5-10 years that this doomsday scenario will be over and they can go and collect their pound of flesh. This time I don't think its going to be so easy. My guess is there will be offers on the table similar to what Dublin City Council proposed over two decades ago.
Your accountant is right, say nothing, pay interest and don't show your hand.
Good luck.
