Holding period question for 1031 exchange

[Nitin Dhiman]

Hello experts,

I believe that for a full tax deferral of profits through a 1031 exchange, I need to have occupied the property for at least 2 of the last 5 years. A rental property that own was occupied by me for the first 18 months of the last 5 years, and was rented out for the remaining 3.5 years. If I sell this property today, would the sale not qualify for a 1031 exchange? Or does the tax due on profits get pro-rated in some way?

Thanks!
