Deduction

You don’t deduct the purchase price but there are deductions such as repairs, depreciation and real estate taxes to name a few. You might want to get professional tax advice at least for your first tax return since the tax issues involved in real estate can be complex. 

You add the house as an Asset then depreciate the cost of the rental over 27.5 years.

Rentals are on Schedule E.  In the search box at the top of your return you can type in rentals and it will give you a Jump to box to go directly to Schedule E.
