@usernamesarehard said "I also claimed loses on it for extensive renovations on the rented side."
"Extensive renovations" cannot be deducted. Te cost must be capitalized and depreciated (deducted) over 27.5 years. The undepreciated part may be added to you coat basis, upon sale, resulting in a reduced caopital gain or even a capital loss.
Q. I am assuming I can still claim the 500k credit for a married couple on the duplex since it is my primary residence. Is this correct?
A. No. When you sell the duplex, you may exclude the capital gain (up to $500K) only on the half that was your principal residence (assuming you owned and lived in it 2+ years).
@usernamesarehard said "This is spread out over multiple years fyi. ie 5 years".
I don't know what that means. The exclusion of the gain on the sale of your principal residence is claimed in the year of sale.
