If you don't qualify for an exceptions (I'm guesing you don't, since I'm sure you would have mentioned it otherwise) or if you are not active duty military that had to vacate the property under military PCS orders, then your look back is only five years. You must have lived in the property for at least 2 years (730 days) of the last 5 years (1826 days) you owned the property, counting back from the closing date of the sale.
