International Property and Capital Gains taxation questions!

[Account Closed]

Hello, new to BiggerPockets!  I have questions regarding my international home sale in South Korea. Hope somebody can help.  

I am a US citizen, living in South Korea, married, filing jointly.  Our salary is $60k. Our home of 3 years has appreciated by $580,000.  Since this is a long term capital gain, I will pay a LTCG tax on anything in excess of $500k. My questions are:

1. Will my taxable income now become $140k (60k + 80k)? Pushing me from a tax rate of 12% to a 22%?

2. Once I get taxed at the 22% tax rate, do I then get an additional capital gains tax on the $80k at 15%?

Thanks!
