Smart refinancing moves once your business outgrows old loans

Once your business grows and your financials improve, refinancing and restructuring can reduce interest, tidy up messy debts and better protect your home. In practice, that can mean moving from an expensive alt‑doc loan to full‑doc, consolidating selected high‑rate debts, and separating business risk from your family home. The trick is knowing what to change, when to act, and how to avoid creating new problems while fixing old ones.

In simple terms: you should revisit your loans once you have at least one or two stronger tax years, a cleaner ATO position and stable cashflow. At that point you can often negotiate sharper pricing, refinance to a better lender or structure, and align business and personal borrowing with your next 3–5 years of goals.

Growth in your business can open better refinancing and restructuring options.

1. How business growth changes your refinancing options

When your business is small or volatile, lenders treat you as higher risk. That often means alt‑doc home loans, extra buffers on business facilities, and tighter limits on how much you can borrow.

Once your business matures, the numbers start working in your favour.

1.1 What lenders like to see once you’ve grown

Most Australian lenders are trying to answer one question: can you reliably afford this loan if rates rise or revenue dips? They typically:

1. Apply at least a 3% serviceability buffer above your actual rate (per APRA guidance).
2. Work from lodged tax returns and financial statements, not draft numbers.
3. Shade your income if it is highly variable or heavily dependent on a single customer.

As your business grows, you improve on several fronts:

• Higher, more stable profit across the last two tax years.
• Cleaner separation between business and personal spending.
• Lower reliance on high‑rate personal or business credit.

1.2 Timing: why two good years matter

For self‑employed borrowers, up‑to‑date tax returns and BAS are often the gating factor for successful refinancing (see fact 18). Most mainstream lenders want at least two years of business financials. A few will work with one strong year plus year‑to‑date BAS, but expect more conservative outcomes.

The ideal moment to review your loans is:

• After lodging a strong latest tax return.
• When any ATO payment plans are in place and running cleanly.
• When business cash reserves are healthy, not stretched.

This timing becomes even more important if you’re planning a new home purchase or investment in the next 12–24 months.

1.3 Signs you’ve outgrown your current loans

You’ve likely outgrown your current set‑up if:

• Your rate is well above competitive offers for similar risk.
• You’re still on an alt‑doc or specialist product despite now having clean full‑doc financials.
• Business facilities are maxed out and being used as permanent working capital.
• You’ve dipped into your home loan multiple times to plug business cashflow.

2. Repricing vs refinancing vs full restructuring

Many owners jump straight to “I need to refinance”. Often, the smarter first step is to reprice with your existing lender, then look at refinancing or deeper restructuring if needed.

2.1 Repricing with your current lender

Repricing means asking your current lender to reduce your interest rate or adjust fees without changing the loan itself. For self‑employed borrowers whose business is performing and LVR has improved, this can be powerful.

You’re in a good position to ask for repricing if:

• Your loan conduct is clean (no missed payments).
• Your LVR has fallen (through repayments or property growth).
• You can point to realistic competitor rates.

2.2 When a full refinance makes sense

A full refinance is moving your loan(s) to a new lender. This makes sense when:

• You’re stuck in an expensive alt‑doc or specialist loan.
• Policy at your current bank doesn’t suit your evolved situation.
• You want to restructure multiple facilities at once (home, investment, business).

Refinancing is more work: new applications, valuations and assessments. But if your business has delivered two strong years and your tax and ATO position are clean, it can materially improve the next 3–5 years of cashflow.

2.3 Restructuring: not just swapping lenders

Restructuring goes beyond rate shopping. It means changing how your debt is organised and what it’s secured against. Typical moves after business growth include:

• Splitting your home loan into separate accounts for home, investments and any consolidated debts.
• Moving short‑term working capital off the home and onto dedicated business facilities.
• Aligning equipment and fit‑out finance terms with the life of the asset.
• Reducing or removing personal guarantees on business debt where possible.

The goal is to keep your effective overall rate sharp without loading more business risk onto the family home than you’re comfortable with.
