In reply to Martin W:
A friend is fortunate enough to be in a similar situation and was asking about this recently. In my mind, a lot depends on your age, and other income/ assets. But a couple of thoughts:
- ISAs are brilliant, no tax on income and get your money out whenever you want. Superb.
- Mortgage are nearly always the cheapest source of debt you can find. So if you expect to have to borrow money in the future, e.g. new car. Then you may be better keeping the money available. Paying a lump to reduce but not pay off may be a good option.
- Your credit rating depends on level of debt, how you utalise debt (borrow for something and payback over time, versus reugulary over spend and dip into overdraft/ credit card), and payment history. Mortgages are a good debt as far as your credit rating, since it was money used for something tangible and debt reduces over time, and the regular payments are also good since they keep your credit rating current.
- Depending on your income, adding money to your pension can give one of the best returns, because you can claim back income tax. But of course the money is locked up.
- Interst rates on savings are poor, but other household bills often include finance costs. e.g. house insurance, car insurance, even some utilities charge pretty steep interest rates, paying up front can provide a good return on money.
- House improvements, especially if you are going to have to do them at some point anyway. e.g. new boiler, replacing windows, etc can provide a good return on money by reducing bills. Future savings on bills can then be invested against future years ISA allowance.
