I'm currently on AIB "Discontinued" variable rate mortgage (2.75%) and I'm considering switching to a fix rate mortgage. The question I have is, once the fixed rate mortgage ends, will I return to the discontinued variable rate mortgage (of course at whatever rate it happens to be then) or will I end up on their new LTV variable mortgages which are more expensive? I've asked AIB, but they were very vague about it just saying that they would issue a letter with different options when the fixed period is up. Also any opinions on how long to fix for? In advance thanks for any help.
