I'm tempted by 0% balance transfer credit cards to reduce the cost of a home improvements loan I have. But this is pointless if it won't cover the balance of around £9500 or if the transfer fee is high or the term is too short. Also, I have read that some credit cards will not allow a balance transfer to pay off a loan. How do you know what the credit limit is likely to be before you apply? It all feels like guess work which is not good when it comes to finances. Any help appreciated!
