When you have chosen a lender and a mortgage product that suits you and have had an offer accepted on a property, the lender will have to arrange a valuation. This is required by the lender to check that they will not be paying a price above the market value, although you will have to pay for it. The cost of the valuation will depend on the value of the property – for example it may be £150 for a £100,000 house. This charge may be waived by a lender to attract your business.
