The Mortgage Rate
This is determined by the value of the property, as well as the size of your deposit. Generally, the more money you can put down for a deposit, the better your mortgage rate will be, since you present less of a risk to the lender. That’s why the products with the lowest loan-to-value (LTV) tend to be found at the top of the charts.
In addition, you may want to compare the deals here with those on offer in the variable rate mortgage charts, as there are some economic circumstances under which variable rates may actually be lower than fixed mortgage rates. However, if this is the case, keep in mind that variable rates can increase beyond the fixed rate in the intervening years. Whether this is an acceptable risk will depend on your specific circumstances and attitude towards risk.
Fees and other charges
Compare deals not just on rates and LTV, but also look at the fees. The three-year fixed mortgage with the lowest rate may look the most appealing, but if it comes with an expensive arrangement fee it can turn out to be costlier overall.
The representative example given for each deal enables you to see the repayments and total cost using set criteria giving you a level playing field on which to compare the costs of different products. Next to this, you’ll also want to work out how much the mortgage will cost you specifically, to make sure you can afford the monthly payments.
Note that some mortgages allow you to add your upfront fees to the mortgage balance. While this could minimise your costs at the time, it also means interest will be charged on this extra debt, likely making it more expensive in the long term.
Aside from upfront charges, it's worth seeing how much you would be charged if you have to cancel the mortgage, too, i.e. the Early Repayment Charge. Even if you never need it, it's better to find out now before it’s too late.
