I would recommend going with BOI on their fixed straight away. If BOI doesn't reduce fixed by time you move, no biggie, as somebody reported recently that their break fee was 100Eur. You could then go to PTSB (2%), then to KBC (3k), then to AIB (lowest rate). Keep moving, keep winning. On 200k mortgage, 4k from boi, 4k from ptsb, 3k from KBC, 2k from AIB. Find yourself a cost effective solicitor and you could make a nice bit of money.
