Yes, these properties are likely QBI eligible. For a rental property to be eligible for the Section 199A deduction, the activity must rise to the level of a business according to IRC Code 162. Prior court cases have established that if the rental activity is a for-profit endeavor, it does rise to the level of a business. Usually this is the case if you are renting the properties at fair rental value for your area.
