Depreciation question

[Aaron Webb]

Hey everyone, 

I have a friend that put his former primary residence as a SFR rental property on 1 Sept 2015. Effectively, this gave him four months of rental income on the property for the year. How long does the home need to serve as a rental to depreciate the full, straight-line depreciation expense (purchase price - cost of land / 27.5 years)? Thanks in advance,
