Just looking for a bit of advice on 'one accounts'. Sounds a bit to good to be true- combine mortgage with current account, ability to overpay/ underpay flexibly. I work full time as a mental health nurse so have a reasonable steady wage. DH is a self employed bricklayer so money varies week to week. DD in nursery taking a large chunk of our income. Fixed rate with the halifax just ended so trying to decide what to do next. One account sounds like it would work for us but not sure? Anybody have one of these accounts and is it working for you?
