What is Quantity Surveyor?
A quantity surveyor is a professional who estimates and itemises construction costs — and, for investment property purposes, prepares depreciation schedules that list every depreciable asset in your property and the tax deduction each generates.
Why it matters for you
A good QS-prepared depreciation schedule can return $5K–$15K+ in annual tax deductions for investment property owners. The QS fee (~$500–$800) is fully tax-deductible in the year paid. Works best on newer properties; still worthwhile on most investment stock.
