Between the two of them, money arrived from four separate places, and not one of those places was a normal full time salary with a payslip to match.
One borrower held two part time PAYG jobs, and also held a minority stake in a small business that paid no wage at all. Their return from that business came as trust distributions. The other borrower worked full time inside that same business, which in lender language makes them a family employee. That matters, because when a business owned by your family pays you a wage, an assessor cannot take the stated figure at face value the way they would a wage from an unrelated employer.
The business itself had traded two full financial years, but the most recent return had not been lodged. Standard self-employed policy wants two lodged years, so on the ordinary path this file could not be assessed at all until the accountant finished.
Then there was the car loan. The business had financed a vehicle, and the borrowers had personally guaranteed that loan. Because they were guarantors, the debt appeared on their personal credit file. A lender's default treatment is to count the full repayment against their personal borrowing capacity, even though the business was the one making the payments. Left unaddressed, they would have been assessed as though they were personally servicing a debt they never actually pay.
With a contract already signed, there was no version of this where anyone waited for the paperwork to get simpler.
