On most occasions the bank will instruct an independent surveyor to value the property and they will provide a figure which the mortgage lending will be based on. The surveyor may also use a desktop valuation process where the valuation is carried out electronically as opposed to physically. If you disagree with the figure, provided you can supply comparable evidence to show that very similar properties have sold for more recently (normally within the last 3 months) most lenders have an appeal process which can be followed.
