We are spending all of our savings and more on the house, so haven't got anything to offset against. We would like to look at using one in the future.
I like the idea of overpaying to reduce the term. The thought of being 50 something and mortgage free sounds nice, whereas currently with our current term I will be well into 60 something before that happens.
I think we will go half way. Overpay into the mortgage but only around half of our savings each month. Put the other half in a savings account to pay for the Kitchen and other things, and leave the mortgage overpayments in the mortgage. We would hopefully then be able to overpay forever, or at least for the considerably future.
