The percentages do not matter and are totally irrelevant. If you lived in the house as your primary residence for at leat 731 days of the last 1826 days you owned it, counting backwards from the closing date on the HUD-1 statement you will receive at the closing when you sell it, then you qualify for the capital gains tax exclusion. Those 731 days do not have to be consecutive either, so long as all of them are in the last 1826 days you owned it. One day short, and you don't qualify.
