How are elements of BRR taxed?

[Micah Epps]

Let's say my wife an I are general managers of an LLC who buys a single family home. The contract price is 100,000. We put 20,000$ of materials and labor into it. We then rent it out for 12 months and cash flow 10,000. We then sell it for 150,000.

Do we pay 15% tax rate on the 10,000 cash flow?

Do we pay long term capital gains on 50,000?

Do we have to pay a property manager for the cash flow to be considered passive income?

How does claiming depreciation affect capital gains?

Thanks everyone in advance!
