I am buying a new house, I hope. The mortgage adviser is keen on offset mortgages and in principle I can see why they would be a good thing.
However I am deeply suspicious of clever financial ideas and I rather feel that this is a good approach: I have not taken out an endowment mortgage, for example, or put money into an Icelandic bank, when that was all the rage.
Can anyone explain to me the downside of an offset mortgage? I feel sure there must be one.
