Hi, I just bought an investment property and am planning to do renovation on it. I read from a website that to maximize the tax deduction, I should get a pre-renovation depreciation schedule. So I can avoid missing out on any valuable deductions before I throw away or demolish them. Then I should also get a depreciation schedule after renovations are done. Do I need to get both pre-renovation and post-renovation schedules from a quantity surveyor? Since I will know the cost of renovation, can my accountant handle the post-renovation schedule for me so I might only need to get a pre-renovation schedule from a quantity surveyor?
