Tax deduction on investment property texas

Hello everyone 

I am considering purchasing an investment property in collins county texas. I am a little bit concerned about the interest rate however if the tax deduction offsets this, that will help me do the purchase confidently

I wish to know

1) is there depreciation tax deduction. If its there, how is it calculated and how much a year

2) is property tax tax deductable

3) pmi tax deductable

4) mortgage interest tax deductable

5) what maintenence and repairs are tax deductable. Please feel free to send me a link to what is dedictable and what is not. Is there a cap on how much deduction can be claimed for maintenence and repair

6) if mortgage is 1000 dollars for example and rent is 700, can i claim the tax deduction for this 300 dollars loss per month. A total of 3600 dollars in one year

Thanks
