unspecified rental income
Found at:
It appears the original poster is trying to combine payments for multiple rental units into one transaction, by assigning multiple property tags to the one transaction: that will not work. A given rental property transaction can be for just one property. That means that you can not assign more than one Property tag to a rental property transaction. [And you can't assign any non-Property tag to a rental property transaction.]
The above Community discussion proves that once again, Quicken rushes to supply useless "help" (lest the user think no one cares if they get no response for a few hours) ... and actually wastes the user's time causing the user to jump through meaningless hoops. Quicken doesn't care enough about actually providing useful information to their users; Quicken's primary concerns are to convince the user that Quicken "cares", and insuring that that no user ever feels offended (even if the user has no good reason to feel offended). The net result: Quicken users may "feel good", but not get useful answers to their questions.
[Note: when a report has "unspecified ... income/expense"; the foot of the report will have a blue link that, when clicked, will show all the possible problems that can cause the "unspecified ... income/expense" indication. Astonishingly, the Quicken moderators continue to ignore that obvious link.]
