Well what would you do in this scenario. At the moment we pay into a joint account 1666 a month. The mortgage repayment is 1340 a month which is an overpayment of 326 a month. At the moment this money is in the account and not overpaying a mortgage. We only started mortgage at the end of last year and wanted to see how we got on making overpayments, so far so good.
So the question is this and maybe it's a stupid one should we overpay our mortgage at 4.5% by 326 a month or should we lock in at a fixed rate of 3.75% where would reduce our monthly payments to 1227 a month and thereby increase our monthly savings to 431 a month. At the end of 2 years we'd have a lump sum of 10,344 euro or after 3 years 15516 which we would then take off the mortgage!
