For your proposed structure, are you going to specifically pay all expenses from each IP offset (eg specify that all expenses for IP A come from IP A's offset account and so on). I am interested in how this works, especially with many IPs.
From your diagram, it sounds as though my description above describes what you are looking to do. Interested how you will specify what account pays what bill, especially as the number of bills and IPs grows - could become quite a task!
Going back to your original post, what are you seeking feedback on? Compliance with tax rules? Availability of funds going forward? Best way to use structure?
What will you be discussing with your accountant? What info are you seeking from them?
Terry has asked some probing questions for you above. If you aren't confident in your accountant, possibly ask Terry if he's willing to do a single appointment to clarify your situation (and possibly a conference call between you/your accountant and Terry if all are agreeable!).
If you're looking for a new loan or loan structure, there are also several brokers on the forum who will correctly structure a loan for you. Just need to be clear about how to use it going forward (either they may be able to explain this to you when the loan is established or see Terry or another tax expert for guidance - there's also Paul@PFI who posts on SS).
It would be good to clarify your central question to direct the thread.
