That's for the buyers to decide, my point was that the sale would influence the prices at which Estate Agents will attempt to market other properties.

There are many things that affect the decision but one of the most important factors the lender will consider is whether their valuation exceeds what is being borrowed against the property so that they don't incur losses in the event that they need to repossess and sell the property. Lenders don't agree to lend a certain percentage of a valuation, they agree to a specific amount of money. The percentage comes into play in assessing risk, offering specific terms/'deals' etc.
