I started using a property as a rental in 2015. Prior to renting it, I lived in it. In entering information for depreciation, I can't figure out if I should put the percentage of business use as 100%, or as the percentage of the year that I used it as a rental property. Putting in the date that I started renting it appears to account for the use of the property for only a portion of the year, i.e. lowers the deduction for depreciation.
