I have a 100k mortgage on a fixed rate (5.9). I've looked at these Current Account/ Flexible mortgages. Is the general idea of having one of these, coupled with every 6 months transferring a balance of about 10k between 0% credit card offers, so that I keep the 10K(hopefully increasing) in my current account and therefore offsetting mortgage interest charges a better deal than what I have now?
Also, what are the best mortages of this type on the market?
