Simply fill in an eight-stage on-line questionnaire, giving details such as the current value of your home, the amount you want to borrow, and your employment status. Eventually, you are given a table with all the best deals ranked according to the true cost of borrowing over your chosen period. If the list is too large, you can filter out loans with redemption penalties, for example, or include only those offering cashback deals. If you find a deal you like, you can apply on-line there and then with most, but not all, of the lenders.
