Capital Gains Exemption

[Roman Kendzerskyy]

Hello! this link was very helpful thank you so much for taking the time to post it. My question is regarding the Capital Gain Exemption...

What if I bought a Property: January 1, 2015 for $500,000

Rented it out until, January 1, 2016 and now value is $625,000

Then I Moved in and lived there for a year until January 1, 2017 and value now is $700,000

and then I sell The Property for $700,000.

Would I have exemption on the entire $200,000 of Gains or would I need to declare the first $125,000... Pay the Capital Gains Tax on that before I moved in And THEN Be exempt from the Remaining $75,000?
