This is a valuation of a property, commissioned by either a seller or purchaser, or by a property-owner wanting to establish the market value.
A market valuation does not result from a detailed survey, but only from a limited inspection. It only mentions those defects that are serious and/or visible at the inspection – not all defects.
You should commission a more detailed survey if you require all of the available information on the condition of a property.
