Thanks for posting your question. Since you are dealing with a multiple entity situation, your first decision is how to enter the multiple entities in QB's. QB's does not support two companies in one company file. However, it is easier if you can structure your company file to break things up by company, with all in one file.
The alternative is to use multiple company files, one per property, and that can be very time consuming and involves more manual labor (after you receive income in one property in the management entity's file, then you need to enter that income allocation for the llc that owns that property. Lots of duplication.
Here's how you can work around it. Note, this is one technique and whatever you do talk it over with your accountants. You can have one company file, in the chart of accounts, have an income account with sub-accounts for each entity. Same with other account types (expense, equity, liabilities). Then through clever reporting you can separate the records by filtering accounts to only show one entity's numbers. This is not an officially supported technique by LandlordAccounting, but it has worked for some others and you might consider it.
