Five Safety Rules To Follow Before Gearing Into Property

Borrowing to invest in property is only safe if you set hard limits first. Five non‑negotiable safety rules are: keep LVR conservative, hold a real cash buffer, stress‑test rates and vacancies, use clean loan structures, and have a written exit plan. If you can’t tick all five, you’re not ready to gear.

This article is the practical companion to broader risk planning guides like Plain-English Gearing Basics Every Australian Property Investor Must Know and Building Safe Borrowing Plans with Buffers, Risk and a Broker.

Five non-negotiable safety rules should frame every geared property decision.

Rule 1: Cap your leverage before the bank does

1.1 Set your own LVR ceiling

Lenders may happily approve you up to 90–95% LVR with lenders mortgage insurance (LMI). That doesn’t mean it’s safe.

For geared property, a sensible ceiling for most investors is:

• Owner-occupied home: Aim to get under 80% LVR over time.
• Investment properties: Target 70–80% LVR total across the portfolio.

Below 80% LVR you generally avoid LMI, improve rate options and have more room if prices fall.

1.2 Understand how much price fall you can survive

A 20–30% fall in property prices is rare but not impossible. Your safety rule should be: “If prices drop 20%, I still want positive equity and no forced sale.”

Illustrative comparison

Your non‑negotiable rule: never gear so hard that a 20% price drop wipes you out on paper.

Rule 2: Build a real cash and offset buffer

2.1 The minimum buffer for geared investors

From our other guides, a practical minimum is:

• At least 3 months of total home + investment repayments in offset or savings (Fact 17).
• For first‑time geared investors, 3–6 months of total property costs (repayments, rates, insurance, basic maintenance) is safer (Fact 16).

A simple rule of thumb: if losing your tenant for six months would break you, you’re over‑geared.

2.2 Worked example: how much buffer is enough?

Assume:

• Home loan repayments: $3,000 per month.
• Investment loan repayments: $2,000 per month.
• Investment holding costs (rates, insurance, basics): $800 per month.

Total geared property outgoings: $5,800 per month.

• 3‑month buffer: $5,800 × 3 = $17,400.
• 6‑month buffer: $5,800 × 6 = $34,800.

Your non‑negotiable rule: keep at least 3 months in cash/offset before you buy, and plan to reach 6 months within 1–2 years. Use offset accounts rather than redraw to preserve flexibility and cleaner tax tracing.

Rule 3: Stress-test your numbers brutally

3.1 Test a 3% interest rate rise

APRA expects banks to test your borrowing with a buffer of at least 3 percentage points above current rates. You should too.

Before you gear, model:

1. Repayments at +3% interest.
2. Zero rent for 3–6 months.
3. 10–20% higher expenses (insurance, repairs, strata).

If you can’t survive all three together without raiding super or taking on new consumer debt, your gearing plan is not safe.

3.2 Focus on pre‑tax cashflow, not tax breaks

With negative gearing set to be restricted for many established properties purchased after 12 May 2026 (Facts 1, 3, 11–15), you must assume:

• Tax benefits may shrink or vanish.
• Cashflow needs to work before tax, not just after.

Your non‑negotiable rule: base the decision on pre‑tax cashflow and worst‑case scenarios, treating tax outcomes as a bonus, not the foundation.

Rule 4: Use clean, flexible loan structures

4.1 Keep properties uncrossed and loans clearly split

Flexible structures are a key safety rule:

• One primary loan per property, often with internal splits (Fact 6).
• Avoid cross‑collateralising your home and investments where possible.
• Use separate splits for different purposes (e.g. deposit/equity release vs main purchase) to keep tax‑deductible debt clearly traceable.

Clean structures make it easier to:

• Sell or refinance one property without disturbing the others.
• Prove deductibility to the ATO.
• De‑gear one loan at a time.

4.2 Protect the family home

Your non‑negotiable rule: protect the roof over your head. That usually means:

• Avoid using the home as the only security for multiple investment properties.
• Where equity is used, structure it as a separate, capped split with a clear repayment plan.
• Prioritise paying down non‑deductible home debt over time.

If your investment choices could realistically cost you the family home in a downturn, the gearing plan is too aggressive.

Rule 5: Have a written de‑gearing and exit plan

5.1 Plan how you’ll reduce risk before you start

Gearing is not meant to be permanent. Most investors should start de‑gearing 5–10 years before retirement, or earlier if cashflow is tight or risk rises. Your plan should answer:

• At what age or net worth will you begin paying down investment debt?
• Which loans will you reduce first – home, highest rate, lowest yield?
• Under what conditions will you sell rather than hold at all costs?

Your non‑negotiable rule: no new geared property without a written de‑gearing path.

5.2 Decide your “stop” signals now

Agree on a few hard stop signals before you buy, for example:

• Two consecutive years of cashflow shortfalls you can’t fix by modest rent rises.
• Portfolio LVR above 80% for more than 12 months.
• Personal income falls (business downturn, job loss) that make you reliant on credit cards or personal loans to cover property costs.

If any of these occur, the pre‑decided action might be: pause new purchases, switch to principal + interest, or sell the weakest asset.

Brutal stress-testing of rates, vacancies and expenses is a key safety step.

Quick checklist: are you really ready to gear this week?

Use this as a yes/no sense‑check:

1. LVR: Will total LVR stay at or under 70–80% after the purchase?
2. Buffer: Do you already hold at least 3 months of total costs in cash/offset, with a path to 6 months?
3. Stress‑test: Have you modelled +3% rates, 6 months vacancy and higher expenses – and can you still cope?
4. Structure: Is each loan clearly split by purpose, with minimal cross‑collateralisation?
5. Exit plan: Do you have a written, time‑bound de‑gearing plan and clear stop signals?

If any answer is “no”, your one‑week task is not “buy a property” – it’s to fix that gap first. Building Safe Borrowing Plans with Buffers, Risk and a Broker is a good next step.

FAQs

What is a safe LVR for geared property investors in Australia?

For most households, keeping total investment property LVR between 70–80% is a sensible upper bound, with lower being safer. Above 80%, you may pay LMI, face tighter refinancing choices and be more exposed if prices fall 20–30%. Your personal safe LVR also depends on income stability, buffers and how close you are to retirement.

How much cash buffer should I have before gearing into property?

A practical rule is at least 3 months of all home and investment repayments in cash or offset before you buy, and a plan to reach 6 months of total costs within 1–2 years. Buffers should be in accessible accounts, not tied up in super or term deposits. If you’d be relying on credit cards to cover a vacancy, you don’t have a real buffer.

How do I stress-test a geared property portfolio against rate rises?

Model your portfolio as if interest rates were 3 percentage points higher than today, rent dropped to zero for 3–6 months, and expenses rose 10–20%. Check whether your cash buffer and regular income could cover that period without new borrowing or selling at a bad time. If not, reduce leverage, build buffers or delay further purchases.

Why is loan structure such a big safety rule for geared investors?

Good structure keeps risk contained and options open. Separate loans and splits by property and purpose make it easier to refinance, sell one asset, or prove interest deductibility to the ATO. Avoiding cross‑collateralisation helps protect the family home and stops one problem loan from dragging down the whole portfolio.

When should I start de‑gearing my investment loans?

Many investors should begin deliberately de‑gearing 5–10 years before their target retirement, or sooner if income becomes less secure or policy risk rises. De‑gearing can mean selling weaker properties, switching to principal and interest, or redirecting surplus cashflow to debt reduction. Planning this before you gear in makes it far easier to execute calmly later.

Key takeaways

• Safe gearing starts with conservative LVRs and hard limits you set, not your lender.
• Real buffers mean 3–6 months of total costs in cash or offset, not just “access to credit”.
• Brutal stress‑testing and clean loan structures are as important as picking the right property.
• A written de‑gearing and exit plan turns gearing from an open‑ended risk into a controlled strategy.
