Anyone with a mortgage would be well advised to make a periodic check on their current arrangements and compare them to market rates being offered. If your mortgage is not currently within a special rate period or not within an extended tie-in period then it makes sense to look at remortgaging if appropriate. Experts suggest that you should at least review your mortgage whenever a special rate period ends. The whole procees of remortgaging has become a little more involved recently with the advent of increased entry and exit charges being applied. The mortgage is currently under investigation about these fees which have seen dramatic increases in recent years. The upshot is that fee calcualtions need to be part of any remortgaging decision.
