I understand that the cost of furnishing an investment property can be deducted from rental income for a number of years, by depreciating that furniture @ 12.5% p/a for 8 years. What happens if we use furniture from our own home... can the original cost of it be factored into the equation? e.g. if the furniture is two years old when we move it into the inv prop, can we reduce the original cost by 25% (12.5% * 2) and then deduct further depreciation from our rental income figure?
