How Small Business Owners Can Gear Into Property Without Losing Everything

If you run a small business, gearing into property is absolutely possible—but the risks are higher and your protections matter far more. The core rule is simple: don’t let one bad year in business take your home or your investment portfolio. That means separating business and household buffers, being careful how you use equity, and matching your loans to the real risks in your life.

Here’s the decision-grade version: 1) never use working capital as a deposit, 2) don’t fund short‑term business needs from 30‑year home loans, 3) keep your home as unencumbered as you realistically can, and 4) stress‑test every geared property against a big drop in business income.

Small business owners run both business and property risks off one household balance sheet.

1. Why gearing into property is different when you own a business

1.1 Two risk engines, one household balance sheet

Employees usually have one risk engine: their job. Small business owners have two: the business and the property portfolio. Both draw on the same household cashflow and equity.

Lenders know this. Most will:

• Count business loans and overdrafts with personal guarantees as personal commitments (Fact 9).
• Apply the standard APRA 3% serviceability buffer on property loans, then effectively apply another buffer in their view of your income.
• Dig into your tax returns, BAS and financials more deeply than for PAYG borrowers.

1.2 The budget changes make mistakes more costly

From 1 July 2027, reforms to negative gearing and CGT will reduce the tax benefits of highly geared established property for many investors. When tax offsets are weaker, pure cashflow and resilience matter more.

For business owners, that means:

• You can’t assume tax refunds will bail out a marginal deal.
• Concentration risk (big debts on a few properties) matters more than ever.

2. Extra risks when small business owners gear into property

2.1 Cashflow risk: when two bad months become a crisis

Your business income is lumpy. Banks still want the same repayment every month.

Worked example (illustrative only):

• Home: $1,000,000, P&I loan $700,000 at 6.5%, 25 years → ~$4,730/month.
• Investment unit: $700,000, interest‑only loan $560,000 at 7.1% → ~$3,313/month.
• Total repayments: about $8,043/month before rates rise.

If your business drawings drop from $200,000 to $130,000 in a slow year (35% down), that $8,000 is suddenly a big slice of your after‑tax income—especially if rent is weaker or vacancies rise.

Roy Morgan data already has around 28% of mortgage holders ‘at risk’ of stress. Add business volatility and you’re automatically further out on the risk curve than a PAYG borrower with the same loans.

2.2 Security risk: over‑using the family home

Most small business owners start by using the home as security—for business facilities, then for investment property. That can snowball into:

• One property securing multiple business and investment loans.
• Complex cross‑collateralisation that’s hard to unwind when you need flexibility.

Remember: using 30‑year home loan debt to fund short‑lived business assets concentrates business risk on the family home and usually increases total interest cost (Facts 2 and 3).

2.3 Mixed‑purpose loans and tax headaches

ATO rules look at loan purpose, not the security property, to determine deductibility (Fact 5). If you constantly dip into home loan redraw to cover tax, wages or stock (Facts 4 and 12):

• You create mixed‑purpose loans that are painful to track.
• You put your home on the line for routine business cashflow.
