I think it won't be long before its above 4%, the way things are going Brendan.
I see banks are doing things in 0.5% increments now, not even 0.25% like in the old days. And if there are to be another few increases in the next couple of years as hinted at, then I would say that 5% isn't unreasonable.
To be honest I am really split at present. Its a nice idea to sit on my tracker for €75k and pay the fairly small amount. Or else go for this house, which I really like, and lose my tracker and end up at the mercy of the banks. Plus pay nearly €2k of stamp duty plus solicitor fees etc.
