In most instances a Quantity Surveyor will conduct a property inspection when preparing a tax depreciation schedule. Sometimes this is not required, for example - if a property has been built by the owner or the Quantity Surveyor has previously inspected a unit within the same complex. A good Quantity Surveyor knows when an inspection is not needed, and this generally results in a saving to the owner/investor. But if certain information is overlooked you will miss out on significant tax deductions.
