Thanks Macstuff, I was fairly sure that Option 1 wasn't a runner but just wanted to check. I agree on Option 2, giving up my tracker is certainly not what I want to do but, again, wanted to float the idea with the experts to make sure my assumptions are correct.
To answer your questions:
a) I've had no communication from the bank re. rates / options as yet - I presume they will contact me in due course but I will contact them today to get the ball rolling.
b) Regarding overpaying the variable loan - I have approx €20k in state bonds which will mature in later this year. I have been thinking about using it to pay a lump off my variable loan, but will I incur a penalty for paying off the loan in this way? Also, I wont get my bonds back until October this year so I will likely miss the opportunity to may a lump sum payment before agreeing new terms with the bank. Any advice you can give me on this is much appreciated.
