Scenario:

In the 5 years before the home was sold, the homeowner lived there for 1.5 years, and rented out the home for 3.5 years.

From 1/1/2015 to 6/1/2015, a renter lived there.

On 6/1/2015, the renter was evicted.

On 6/15/2015, the house was put up for sale.

On 9/1/2015, the house was sold.

For tax reporting, is this a sale of residential home? Or a sale of rental home?
