10/2013 we purchased our home and lived there until 7/2015. House became a rental and we sold it 6/2019. Would this be a sale of home or business property?

The house was not intended to be a rental. We purchased it as our primary home and lived there until we had to move for my husband's job. I have tried researching the forums, etc and I have gotten information going both ways. For the 5 years prior to the sale, we lived there 1 month (2 if you count the time it was vacant before renting). According to some, this makes it the sale of a home.

Since it was used as a rental, some told me it was the sale of a business property.

Just not sure what to list it as...
