We rented the attached, one-bedroom apartment for many years. The apartment is attached to the house, but has private entrances and it's own electric meter.  There is a door, lockable from both sides, into the apartment from the front hall of the house, and there is one gas and one water meter for the whole house.  For previous years I used TurboTax Premier and reported income and expenses for the apartment. In 2017 we had no renters, suffered water damage from a leaking roof and a busted water pipe. We used the apartment solely for personal use and stored stuff in it.  It is unlikely that we will have renters this year, and are likely to sell the house later this, or next year.  So far, I have entered no information in TurboTax for our 2017 return suggesting that we have a rental property, but I don't know if that will raise any red flags to the IRS. Is that the correct way to report nothing?
