What are the "transfer" line items in my ledger?

For owners with multiple units, we shift balances between ledgers before making any payouts. Let's say you have two units: Unit A and Unit B. Unit A has a $500 outstanding balance, and Unit B has no balance. If you receive $800 in rent from Unit B, $300 of it will pay out to you, and $500 will be transferred to Unit A to zero out the $500 outstanding balance there. Each transfer to a different unit will have a line item showing the amount of money moved and the destination of the money.
