[This is a Sponsored Post] I don't understand too much about mortgages; apart from the fact that I hope to get one, one day. I've seen the One Account adverts that say that they have a revolutionary system that will shrink your mortgage. Basically, this debt of a mortgage is combined with your current account, so that your salary is offset against it reducing it over a period of time. You can also put anything lef tin your account at the end of the month towards your mortgage; shrinking it with no penalty fees. Plus they let you take payments breaks. Sounds good to me.
