Investors & landlords

I have not lived in this house at all for past 23 years so no personal use.  I don't plan to live in it in the near future.  Given it is a tourist area and judging by the bookings for first quarter of 2017, I will make a profit in 2017 and triple the income I would have made as regular rental.  I am hoping to have at least some tax advantage in being able to deduct either special depreciation (items under 2500) or long term depreciation over next coming years.
