All income and expenses are reported on the Sch E if the property was available for rent or being repaired EVEN if the place is vacant for a time.
For instance renters move out in January and you had to make repairs so the place was vacant for 3 months, then you put it back on the market but you didn't get a renter in again until December. So for the entire year you can take the regular carrying expenses and the depreciation on the Sch E. Read the IRS Publication 527 for information on being a landlord.
