Hi,
It's worth while having a chat to a couple of Quantity Surveyors about your property. Quite a few of them have a guarantee that they will return double of the cost of getting a tax deppreciation schedule done in the first year. And if they don't think that they will be able to, they will tell you upfront. I know that both BMT and Depreciator do this and they are both excellent companies.
Wishing you every success, Ana
