Taxes on a Flip Bought prior year.

[Leon Chappell]

Hey, Lets say I bought a flip in 2018 for $100,000 and I sold it in 2019 for $150,000. Do I deduct the $100,000 purchase expense on my 2018 taxes or my 2019 taxes? If its the 2019 taxes, will I be taxed on the full 150,000 amount, or just the $50,000? I just want to know how to break down the taxes on my flip If I sell it in another year other than the year I purchased.
