Investors & landlords

@ash023 Note the screens in the screenshots below.

Re the last screenshot, note that you do NOT enter personal use days for the days prior to when the property was placed in service as a rental.

The example @Carl stated in the previous post is applicable to vacation rental property. 

Frankly, in your scenario, it is easier to simply tell TurboTax that the property was rented all year in the Property Profile section (i.e., answer "YES") and then do the split yourself, which would likely only be mortgage interest, property taxes and insurance.
