I take it,given the mortgage is only a year old,that you were not previously on a tracker.
SVR rates are the only show in town that allows banks to increase their profit margin,money will continue to be very expensive for Irish banks to borrow,meaning SVR customers will be getting an awful kicking in rate hikes.
If it were me and I had no plans to move anywhere in next 5 years I wold be looking at fixing for that duration.
I am no expert though,just what I would do,given these strange days we find ourselves in,I would prefer the security of knowing exactly what I was paying out each month and not be living in dread of hearing news of further rate hikes out of the blue.
Is it good rate 5%? it probably will be in a years time,but that ship will have sailed at that stage,all opinion,purely speculative.
