Investors & landlords

The key is that you rented the property 100% after you converted it from a personal residence to a rental property. There is no 'multi' use after the conversion. You should prorate  your real estate taxes, insurance and mortgage interest yourself. Follow the steps below so that all direct rental activity expenses are used at 100%. 

Here are the steps to get to that section so that you can enter your expenses that are 100% for the rental activity (no personal expense portion).

1. Open your return in TurboTax Online/Mobile or TurboTax Desktop
2. Search (upper right) Type rentals > Click the Jump to.. link
3. Select Edit beside Rental Property Info > Select Edit under Situations  > Continue
4. Select Converted home to rental or rental to home > Continue > Select From primary residence to rental > Continue
5. Select the same on the next screen > Select 'Yes' property was rented all year - You will break down any expenses that do not pertain to the rental period.
6. Select 'Yes' it was always rented at fair rental value (FRV) > Continue
7. Enter your expenses yourself and they should be at the amount you entered

Likewise the rental house will be added as an asset (must have a separate land value) and you will enter the date it was placed in service. TurboTax will handle the correct depreciation. Enter any additional assets for your rental activity.
