Investors & landlords

Sir/Madam, I am a UK citizen, submitting IR1040 tax return I bought a property in Miami in March 2011for $82000 in May 2019 ,sold $154000. In the cost can I claim depreciation, indexation, and taper relief. What all forms I should submit?

 

I incurred loss $13000, in 2015, when I sold another property in  Davenport. Can I set aside that on 5he current gain.
