I really like the idea of just using classes to identify multiple rental properties in one company.  It keeps things simple.  Unfortunately, the IRS likes to complicate things and requires each property to be listed separately on Form 8825 (A, B, C, etc). So ideally you would be able to map a class to a tax line instead of having to setup each income and expense category with each of the properties in order to map to a separate tax line. But I'm guessing that type of feature is not supported by Quickbooks. So my question is, will I really need to setup multiple properties under each income and expense item in order to map them to separate properties for IRS reporting?
