first depreciation allowed or allowable during the rental period must be recaptured as section 1250 gain
of the remaining gain, the amount that does not qualify for 121 treatment (ie exclusion) is period of rental (nonqualified use) divided by period of ownership times $250,000 (assuming you're not married)
period of nonqualified use is any time after 2008 when it was not used as your personal residence.
using your net gain of $200K say $15K was depreciation allowed or allowable. that gets taxed as section 1250 gain, that leaves $185 of gain
say you sell it 10/1/2024. (your months don't quite add up so)
period of ownership: say 8/1/2009 to 9/30//2024 = 182 months
period of nonqualified use 7 years (the months rented) = 84 months
nonexcludable gain 84/182 times $250K (assuming you are not married) or about $115K that will be taxed as long-term capital gain. the remaining gain of $70K is excludable.
