Help: Rental Property Calculation

This is the first year we have rental income(passive), and doing tax planning now, could anybody help point out if I got the direction right? Thank you very much!

For example as below with dump simple numbers:

  • Annual Rental Income: $30k
  • Expense including cleaning, travel, advertise, HOA, insurance etc.:$2K
  • Property tax: 5k
  • House deppreciation: assume it's a new house, value 275k(exluding land value), annual deppreciation is 10k(?)
  • Mortgate principal: 10k,interest 10k.

1. So total rental income is 30-2-5-10 = 10k? Not sure if the mortgate&interest will count as cost as well?

2. If I have 100k taxable salary income,   does the property tax 5k and mortgate interest 10k still bring my taxable income down to 85k?
