Is it a good idea to break your fixed-term loan to take a better deal?

OPINION: I recently contacted my bank about the possibility of paying off a chunk of my mortgage early.

We were moving house and thought – wrongly, as it turned out – we might be able to reduce our mortgage in the process.

We asked about paying off a $50,000 on a loan we fixed two years ago at 6.25 per cent. (Not the best decision I've ever made.)
