A lender valuation isn’t a survey. It’s a limited check on the property that your mortgage lender carries out to ensure it’s worth the money they’re lending you. They’ll probably ask you to pay for the valuation. The property may not even be visited. Lenders may provide a copy of the mortgage valuation to the buyer but it is unlikely to cover items of detail which would be picked up in a survey. There may be problems in the property that would cost a huge amount to put right – and they won’t appear in the valuation report. This is why it’s really important you have a proper survey.
