1. Change your attitude to your mortgage
Unless you make the mistake of buying a train ticket in Britain on the day of travel, the most expensive item you are ever likely to buy is your home. If you're not in the privileged position to pay cash, make sure the loan you use to finance it is the best available. For example, if you are paying your lender's full standard variable rate (SVR) you are probably paying hundreds of pounds a year more than you need to. There are thousands of deals to choose from and while it is vital to check the small print for hidden catches, this is a relatively easy way to save a lot of money. Remember: loyalty to your bank benefits your bank, not you.
