Step‑By‑Step: Using Home Equity To Buy Your Next Investment

Using existing equity to fund your next investment property means borrowing against the value of your current home or investments to cover the new deposit and costs instead of saving cash. Done well, you keep sensible loan‑to‑value ratios (LVRs), separate investment and home debt, and stress‑test repayments at higher interest rates before you sign a contract.

In this playbook, you’ll see exactly how to:

1. Work out your usable equity.
2. Turn that equity into a new loan split.
3. Structure the new investment purchase.
4. Avoid common tax and structure traps.
5. Build a one‑week action plan you can execute now.

1. Equity basics: what you’re actually using

Before you start talking deposits, you need a clear view of what equity you can safely touch.

1.1 Total equity vs usable equity

Total equity is simply:

Property value − Current loan balance

But lenders and sensible investors don’t let you use all of that. As explained in /insights/equity-strategies-property-investors, you usually work off usable equity, which builds in a safety margin.

A common guide is:

Usable equity ≈ (Property value × 80%) − Current loan balance

Staying at or below 80% total LVR typically avoids Lenders Mortgage Insurance (LMI) and gives you more flexibility in future.

Worked example

• Home value (bank valuation): $1,000,000
• Current home loan: $500,000
• Target LVR: 80%

Usable equity ≈ ($1,000,000 × 80%) − $500,000
= $800,000 − $500,000
= $300,000 usable equity

In simple terms, you could create a separate split of up to $300,000 for investment purposes and still sit around 80% LVR on the home.

1.2 Why 80% is the magic line (most of the time)

You can often borrow above 80%, but it usually means:

• Paying LMI or an LMI top‑up.
• Stricter lender assessment and APRA’s 3% buffer biting harder.
• Less room to move if values dip or rates rise.

Most investors using equity aim to:

• Keep their home at or below 80% LVR; and
• Accept higher LVRs (up to 90–95% with LMI) on the investment property if needed.

2. Step‑by‑step: using equity as your next deposit

Here’s the high‑level sequence before we drill into numbers and structures.

2.1 The end‑to‑end process

1. Confirm your property values (desktop or full valuation).
2. Calculate usable equity on each property.
3. Decide your target LVRs (home vs investments).
4. Refinance or top‑up to create a new, clearly labelled investment loan split.
5. Use that split as your deposit and costs for the new purchase.
6. Take a separate investment loan secured against the new property for the balance.
7. Set up offsets and buffers, then monitor cashflow.

This is the same logic whether you’re buying a house, unit or an off‑the‑plan apartment (for off‑the‑plan specifics, see /insights/using-equity-off-the-plan-deposit).

2.2 Turning the concept into a realistic budget

Let’s extend the earlier example.

• Home value: $1,000,000
• Current home loan: $500,000
• Usable equity at 80%: $300,000
• Target new investment purchase: $800,000
• Estimate purchase costs (stamp duty, legals, inspections, loan costs): say 5% ≈ $40,000 (varies by state).

You might structure it like this:

1. Equity loan split on home: $250,000

   • $160,000 for 20% deposit on $800,000 purchase.
   • $40,000 for costs.
   • $50,000 left as a buffer or for small renos.

2. New investment loan on the new property: $640,000 (80% of $800,000).

Your total borrowings now:

• Home loans: $500,000 (original) + $250,000 (equity split) = $750,000.
• Investment loan: $640,000.
• Combined property debt: $1,390,000.

Key question: can your cashflow genuinely handle this, using a higher test rate? We’ll come back to that.

3. Structuring the loans: splits, security and tax cleanliness

The way you structure the loans matters almost as much as how much you borrow.

3.1 Why separate loan splits are non‑negotiable

For clean tax and flexibility, you generally want:

• Existing home

  • Split A: Original home loan (owner‑occupied).
  • Split B: New investment purpose equity release.

• New investment property

  • Split C: Investment loan secured solely against the new property.

This reflects a key principle from our broader equity work: keep each investment purpose in its own clearly labelled split to simplify tax deductibility and refinancing later (see /insights/releasing-equity-from-your-home-safely).

3.2 Offsets vs redraw: don’t contaminate your tax position

If you release equity before you’re ready to settle on the new property, you’ll often park the funds temporarily.

Better practice is to:

• Use an offset account linked to the equity split to hold surplus cash.
• Avoid using redraw for mixed personal/investment spending.

Why? As our restructuring guides explain, using redraw on an investment loan for personal expenses can contaminate deductibility and create messy record‑keeping. Offsets leave the loan balance untouched while still reducing interest.

3.3 Principal & interest vs interest‑only

Most investors consider:

• Home loan: Principal & Interest (P&I), to steadily reduce non‑deductible debt.
• Investment splits: Sometimes Interest‑Only (IO) for 3–5 years, to maximise immediate cashflow and potentially deductible interest.

But IO isn’t a free lunch. Lenders will stress‑test your repayments as if they were P&I at a higher rate, and IO debt doesn’t reduce unless you actively park extra in offset.

Work with your broker and accountant to:

• Ensure the structure matches your overall strategy (e.g. debt recycling, retirement timing).
• Plan for the IO period ending and higher P&I repayments later.

3.4 Avoid cross‑collateralisation where possible

Whenever practical, aim for:

• Each property standing on its own security (or with clearly defined internal splits).
• Avoiding one giant loan covering multiple securities.

This usually makes it easier to:

• Sell or refinance one property without renegotiating the whole portfolio.
• Manage bank risk if one property underperforms or a lender tightens policy.

4. Worked repayment example: can you actually afford it?

Let’s run the earlier numbers through some indicative repayments (these are examples only – not live rates).

4.1 Baseline assumptions

• Home loan Split A (P&I): $500,000
• Home equity Split B (IO, investment purpose): $250,000
• Investment loan Split C (IO, investment property): $640,000
• Assume 5‑year IO on the two investment splits; 25‑year remaining term on home.
• Illustrative interest rate: 6.5% p.a.
• APRA buffer: serviceability tested at 9.5% p.a. (6.5% + 3%).

Approximate monthly repayments at 6.5%:

• Split A (P&I, 25 years): ≈ $3,380/month.
• Split B (IO): ≈ $1,354/month.
• Split C (IO): ≈ $3,413/month.

Total monthly repayments ≈ $8,147 at 6.5%.

At a 9.5% test rate:

• Split A (P&I, 25 years): ≈ $4,379/month.
• Split B (IO): ≈ $1,979/month.
• Split C (IO): ≈ $4,987/month.
• Total assessed repayment ≈ $11,345/month.

Lenders will assess your income and other debts against the higher figure. You should too when you run your own numbers.

4.2 Rental income and buffers

Say your new investment property rents for $900/week = ~$3,900/month. Lenders typically shade this (e.g. to 80%) to allow for vacancies and costs, so they might only count around $3,100/month.

You want to see what happens if:

• Interest rates rise another 1–2%.
• The property is vacant for 2–3 months.
• Major expenses (hot water, strata levy spike) hit at the same time.

A good rule from our first‑time investor work is keeping 3–6 months of total property costs (mortgage + rates + insurances) as a cash buffer. You can hold that buffer in an offset attached to your home or an investment split.

5. Key lender rules that shape your equity strategy

Most major lenders will look at the same core factors when you use equity to buy again.

5.1 LVR and LMI: where the lines are

Here’s a simplified comparison of common LVR bands and what they usually mean.

*Indicative only; policies differ by lender and over time.

You might accept a higher LVR on the investment property itself while keeping your home under 80%. That balance is often more important than the combined portfolio LVR.

5.2 Serviceability and existing debts

Lenders will look across your whole position:

• Personal credit cards and Buy Now Pay Later.
• HECS‑HELP and personal loans.
• All existing mortgages, even if IO.

Each extra liability erodes your borrowing power. Before a big equity move, many clients:

• Cancel unused credit cards or reduce limits.
• Consolidate high‑interest personal debts into a clearly labelled split, then pay it down aggressively (see /insights/mortgage-brokers-refinance-debt-consolidation-equity-release).

5.3 Employment and self‑employed income

If you’re self‑employed, expect lenders to:

• Look at 2 years of tax returns and financials.
• Use average or lower‑year income.
• Add back some non‑cash expenses but ignore others.

This is where having the same person who understands your tax and lending position can be powerful. For example, how you pay yourself (salary vs dividends vs distributions) can change your borrowing capacity.

6. Tax, new negative gearing rules and your equity plan

Borrowing against equity for investments usually means the interest on those investment‑purpose splits is potentially deductible. But Australia’s 2026–27 Budget reforms mean you need to be more deliberate.

6.1 Negative gearing – what’s changing

Current proposals (as at mid‑2026) mean:

• Established residential properties bought after 12 May 2026: rental losses generally cannot be offset against salary or wage income. Losses may be quarantined against future rental income or gains.
• New builds: negative gearing is expected to remain available beyond 1 July 2027.
• Properties held before 7:30 pm AEST on 12 May 2026: broadly grandfathered under the old rules.

This doesn’t remove the value of using equity, but it changes:

• How valuable a large, negatively geared loss really is.
• Whether you target new builds vs established for your next buy.

6.2 Clean tracing and documentation

Because loss quarantining and CGT rules are getting more complex, it’s more important that you:

• Keep each investment property in its own split or combination of splits.
• Avoid mixing private spending into investment redraw.
• Keep clear records of what each loan split funded.

That way, your accountant can:

• Identify which interest is deductible (and under which regime).
• Apportion correctly if the property’s use changes later.

6.3 When tax shouldn’t drive the bus

Even with negative gearing on new builds, the priority questions remain:

• Is the property quality and location strong enough for long‑term growth?
• Can you comfortably service the debt on post‑tax cashflow, not just pre‑tax projections?
• Do you have buffers to handle vacancies and rate rises?

Tax is important, but it’s the second‑order decision after cashflow and risk.

7. One‑week action plan: from idea to decision

If you’re reading this with a busy week ahead, here’s a realistic sequence you can follow.

Equity release turns part of your home’s value into a separate investment loan split.

Day 1–2: Clarify your numbers and goals

• Pull together recent loan statements, rates and remaining terms.
• Estimate your home and investment property values (start with realistic online estimates, then plan for formal valuations).
• List your after‑tax household income and all recurring expenses.
• Clarify your aim: one more investment over 5 years? debt‑free home by 60? support a business?

Day 3–4: Talk to a broker who understands tax

Book a short strategy session with a broker who also understands the tax side. In that session, you want to cover:

• Estimated usable equity on each property.
• Borrowing power at today’s rates plus a 3% buffer.
• Rough price range for your next purchase and whether it should be new or established given the 2026 reforms.
• Initial thoughts on loan structure (splits, IO vs P&I, offsets).

If you already run a small business, also discuss whether equity should be reserved partly as a business safety buffer, drawing on principles from /insights/using-investment-property-equity-support-small-business.

Day 5–6: Valuations and structure design

• Authorise your broker to request bank valuations (desktop or full).
• With real valuations, confirm:
  • Target LVRs on each property.
  • Maximum safe equity release (not just what a bank will allow).
• Design the split structure in writing: which split funds which property, which offsets sit where, and the repayment settings.

Designing the right loan structure is as important as how much you borrow.

Day 7: Decide your next move

By the end of the week you should be able to decide between:

1. Proceeding: lodge a refinance/equity application on the agreed structure and start firming up a buyer’s brief.
2. Pausing: if buffers or serviceability are tight, set a 6–12 month plan (e.g. pay down credit cards, build savings, increase income) before using equity.
3. Restructuring first: optimise your current loans and buffers without committing to a new purchase yet.

The goal isn’t to force a purchase; it’s to move from vague “I should use my equity” to a clear, written plan.

8. Common mistakes to avoid when using equity

Using equity safely means balancing growth ambitions with realistic cash buffers.

8.1 Treating equity as free money

Equity is debt, not cash. Every dollar you draw increases:

• Your interest costs; and
• Your exposure if prices fall.

Always tie equity release to a clear, investment‑grade purpose – not lifestyle creep.

8.2 Blending personal and investment purposes in one split

One of the biggest long‑term headaches is using a single equity split for:

• Investment deposit; and
• Car, holiday, school fees.

This makes tax deductibility messy for years. It’s usually cleaner to:

• Create separate splits for each purpose, even if all are investment; and
• Keep personal spending inside non‑deductible home loan splits or specific personal loan facilities.

8.3 Over‑optimistic rent and growth assumptions

Assume:

• Lower rent than agents quote; and
• Slower capital growth than the last boom.

Test your plan at:

• 1–2% higher interest rates; and
• Zero capital growth for 5 years.

If it still works, you’re on more solid ground.

8.4 Ignoring future life changes

Ask yourself:

• Are kids, school fees or parental care costs on the horizon?
• Do you plan to cut back work within 5–10 years?
• Is business income volatile?

Structure your borrowings so that future you isn’t boxed in. Sometimes that means using less equity than the bank will happily offer.

9. Bringing it all together

Using equity to fund your next investment property isn’t just a finance trick. It’s a full‑picture strategy that connects:

• Sensible LVR limits and clean loan splits.
• Realistic cashflow modelling under APRA’s 3% buffer.
• New tax rules on negative gearing and CGT.
• Your personal goals over the next 10–20 years.

If you approach it with that mindset, your equity becomes a tool to build long‑term security – not a way to quietly drift into stress.

FAQs: using equity for an investment property deposit

1. How much equity do I need for my next investment property?

In many cases you’ll want enough usable equity to cover at least a 20% deposit plus 4–6% for costs, using an 80% LVR cap on your home. For an $800,000 purchase, that’s often around $200,000–$210,000. You can buy with less by accepting LMI on the investment property, but you still need to pass serviceability tests and keep sensible buffers.

2. Can I use equity from more than one property for the same purchase?

Yes. Many investors release equity from both their home and an existing investment. Practically, this usually means setting up separate investment splits against each property, then combining those funds for the new deposit and costs. Lenders will assess the overall LVR and cashflow impact across your whole portfolio, so it’s important to plan the structure carefully.

3. Is the interest on my equity loan tax deductible?

Interest can generally be deductible where the purpose of the borrowing is to buy an income‑producing investment property. That’s why it’s so important to keep equity used for investment in a separate split, and not mix in personal spending. The new negative gearing and CGT rules make clean tracing and good records even more important, so always confirm the position with your tax adviser.

4. Should I fix or stay variable when I release equity?

It depends on your risk tolerance and plans. Variable rates provide flexibility to restructure, pay extra and refinance, which many active investors value. Fixing can give repayment certainty for a period but may limit changes to structure or extra repayments. Many clients use a combination: part fixed, part variable, aligned to their investment horizon and comfort with rate risk.

5. What if my bank valuation comes in lower than expected?

A low valuation reduces your usable equity and can stall your immediate plans. Options include ordering a second valuation via a different lender, improving the property before re‑valuing, scaling back the purchase price range, or delaying the next purchase while you pay down debt or build savings. In some cases, restructuring with your current lender for better terms is the first step before attempting another equity release.

Key takeaways

• Work off usable equity, not total equity – usually targeting around 80% LVR on your home.
• Always use separate, clearly labelled loan splits for investment equity release to keep tax and refinancing clean.
• Stress‑test repayments using at least a 3% higher rate and allow for conservative rent and periods of vacancy.
• Understand how the 2026–27 negative gearing reforms affect your choice between new and established properties.
• Keep a 3–6 month cash buffer in offset to protect against rate rises, vacancies and surprises.
• Treat equity as a strategic tool, not free money – let your long‑term goals set the limits, not the bank.
