How to Restructure Overdrafts Before You Apply for a Home Loan

Restructuring overdrafts and working capital before a home loan is about tidying limits, structures and transactions so lenders see a stable, well‑run business, not about starving the business of cash. For most owners, 2–3 targeted changes over the next few weeks can lift borrowing power and reduce risk to the family home.

Quick answer: cleanly separate business and personal accounts, right‑size overdraft limits, move long‑term debt into term loans, and avoid using home‑loan redraw or personal offset as recurring working capital.

A simple overdraft restructure plan can strengthen both your business and home loan application.

Why overdrafts hurt home loan approvals more than you think

Home loan assessors don’t just look at what you owe today. They look at what you could owe tomorrow.

1. Limits count, not just balances. If you have a $100,000 overdraft limit, many lenders treat the full $100,000 as potential debt, even if you only sit at $20,000 most of the year.
2. They add APRA’s 3% buffer. A facility assessed at 8% p.a. becomes 11% for serviceability, inflating the ‘assumed’ repayment.
3. Messy transactions are a red flag. Using business overdrafts for personal living, or personal accounts as business working capital, signals under‑funded trading and poor structure. That can spook credit teams and reduce how much they’ll lend.

This is why restructuring is powerful. You often improve your home loan position just by matching the type and size of each facility to its real purpose.

Step 1: Separate business and personal – non‑negotiable

If you do nothing else, do this.

• Separate bank accounts. One personal account for household income and spending. One or more business accounts (including overdraft) only for trading.
• Stop using home loan redraw/offset for business. Using redraw or offset as revolving working capital is one of the fastest ways to create messy, mixed‑purpose loans and is treated by lenders as a sign of under‑funded cashflow (see /insights/ato-debt-payment-plans-working-capital-lender-view).
• Move personal expenses off the overdraft. Wages, groceries, school fees and Netflix should run from personal accounts, not through the business facility.

Aim for at least 3–6 months of clean separation before you apply. That gives lenders a clear story: the business funds itself; the household lives within its means.
