Investors & landlords

can deduct the mortgage interest twice?

Of course not. If you converted the property from personal use to rental in 2019, then mortgage interest and property taxes is prorated on the SCH E for the period of time it was classified as a rental. The remainder is a SCH A itemized deduction.

The property insurance also has to be prorated on the SCH E for the period of time it was a rental. For the period of time it was personal use, the remainder of the property insurance is *not* deductible anywhere on your tax return.

If you elect to have the program do the splits for you, it will do so with the mortgage interest with no problem. But not for the property taxes or insurance. You'll have to figure those manually.
