Rent payments that have been offset and not paid out to the landlord can be unwound from the original transaction. This will allow any remaining funds to be reassigned.
Navigate to Properties > Property Balances and into either the landlord or tenant ledger for the property in question
On the top right of the page, click on Bank lines
Against any of the Offset rent bank lines, under Transaction Type, it will show the ID of the bank line that was originally offset
Click on the ID number of the original line
In the new screen, click Remove offset rent lines
This process will only unwind the portion of the original transaction that has not been paid out to the landlord yet. Any funds not yet paid out to the landlord will now appear in Financials > Unassigned lines to be reallocated as required.
