A mortgage rates cost breakdown should include the interest rate, monthly repayment, arrangement and valuation fees, product or broker fees, and any early repayment charge. For example, borrowing £200,000 over 25 years at 5% interest could mean repayments of roughly £1,170 a month, although the exact amount depends on the mortgage type and lender’s calculation. Compare the total cost over the initial deal period, not just the headline rate, and check what happens when a fixed or discounted deal ends. An FCA-authorised mortgage adviser can help compare suitable options for your circumstances.
