Can I deduct the mortgage, taxes and Insurance for my rental in Puerto Rico from my taxes I file in the U.S.?

I live and work in california and file taxes here. This year I bought a rental in Puerto Rico and am wondering what I can deduct from the taxes I file in the U.S. and what I have to deduct from taxes I will file in PR. For example: which expenses can I deduct from when I file in the U.S.: Mortgage, Taxes and Insurance, Homeowners Association, operating expenses, advertising expenses, start up, etc. Where can I find more information about this?
