Question - 20% Trump pass thrgh Deduction- income threshold $157k

[Ray Slack]

Okay.. I have read up thoroughly on the 20% pass through deduction and have a question about this hypothetical person. 

Schedule C for Subchapter S -construction business Net income $50,000

Rental Property gross annual income $50,000 per year.  Rental property Net income is about $40,000 not including depreciation.

Long term Capital Gains income on sale of rental investment property.  $50,000

So I am correct to assume it would be 20% on just the Schedule C income? $50k x 20% = $10,000 ?

or would it be:

20% deduction on schedule C and 20% deduction on net rental income? $90k x 20% = $18,000  ??
