??? You said you moved in to it in June 2016 and implied it was rented since 2014. Now you say you had it for years before renting it. What was the property used for before it was rented, and for how long?
As Carl said, you depreciate the LOWER of the Adjusted Basis and the Fair Market Value. That means you need to first find out the Adjusted Basis of the person who gave you the property.
