Using equity to buy investment property means borrowing against the usable part of an existing property's value instead of selling it. Usable equity is generally based on the lender's valuation, the maximum loan-to-value ratio (LVR) and your current loan balance. Approval still depends on income, expenses, debts and lender policy, so confirm the numbers with a mortgage broker or lender before you choose a property.
Your home or existing investment has probably risen in estimated value, and you are wondering whether that gain can fund the next purchase. It can in some cases, but the number on a property app is rarely the number a lender will use.
The sharper question is how much equity is usable, how much extra debt you can service and what role the next property will play. Buyers Agency Australia offers strategy-led property investment guidance built on that logic: equity should fit a wider investment strategy before it is released.
This guide covers the calculation, lender process, loan structures, costs, risks and residential versus commercial differences when using equity to buy investment property. It is general information only, not personal financial, tax, legal, lending or self-managed super fund (SMSF) advice.
Can I use equity in my home to buy an investment property?
Potentially, yes. Equity is the gap between what a property is worth and what you still owe on it, and Westpac's explanation of investing with equity makes clear that only part of that gap is typically accessible. Think of equity as borrowing power secured against an asset, not cash sitting in the bank.
The risk side matters just as much. ASIC's Moneysmart sets out the risks of borrowing to invest, including larger losses and exposing the property used as security.
| Concept | What it means | What decides it |
|---|---|---|
| Total equity | Property value minus the loan balance | Market value and current debt |
| Usable equity | The portion a lender may let you borrow against | Lender valuation, maximum LVR, loan balance |
| Borrowing capacity | How much extra debt you can service | Income, expenses, debts, credit history, lender policy |
Total equity and usable equity are not the same
Lenders generally cap lending at a percentage of their own valuation, so usable equity is smaller than total equity. A buffer stays in the property by design.
Can equity act as a deposit? Often it can fund part or all of one, but the money comes from a new loan, and purchase costs still need funding.
Equity is not the same as borrowing capacity
Does having equity mean you can borrow more? Not by itself. Equity shows what a lender may be willing to secure against, while borrowing capacity shows whether your income can carry the repayments.
How much usable equity can you use?
The short version is a formula, followed straight away by a warning. Usable equity is a starting point for planning, never a purchase budget.
The basic usable-equity calculation
Illustrative maximum lending amount minus existing loan balance equals potential usable equity.
The maximum lending amount is the lender's valuation multiplied by its allowable LVR, and how lenders explain usable equity shows why that percentage is lender-specific. This is why using equity to buy investment property starts with a lender-assessed valuation, not an online estimate.
Keep these caveats in view:
- Lenders set the valuation, and online estimates can differ.
- Maximum LVR varies by lender, borrower and loan purpose.
- Usable equity may cover only part of the deposit and purchase costs.
- Usable equity does not set your purchase price; serviceability does.
A hypothetical example using a lender-assessed valuation
Every figure here is hypothetical and is not a borrowing estimate or approval outcome. Assume a lender values your property at $800,000, your loan balance is $450,000 and the example uses an illustrative 80% LVR, a figure lender guides commonly use for illustration.
- $800,000 x 80% = $640,000 illustrative maximum lending
- $640,000 minus $450,000 = $190,000 potential usable equity
Now assume the valuation returns at $750,000. The same 80% gives $600,000, so potential usable equity falls to $150,000, a $40,000 gap you may need to cover from savings or by changing the plan.
How the equity-release process works
For anyone using equity to buy investment property, the release usually follows five steps, though the order and detail vary by lender.
- Confirm the current valuation and loan balance. What can go wrong: a lower valuation than expected.
- Check serviceability with a broker or lender. What can go wrong: income, expenses or debts limit the new loan.
- Obtain conditional approval or pre-approval. What can go wrong: conditions are not met before the contract deadline.
- Release or restructure the equity. What can go wrong: the structure is not ready before settlement.
- Fund the deposit, costs and settlement. What can go wrong: purchase costs were underestimated.
Confirm the current valuation and loan balance
Start with a lender valuation, because it controls every number that follows. Ask your broker for the current loan balance and any redraw or offset position at the same time.
Check serviceability and obtain conditional approval or pre-approval
Serviceability is tested against your income, expenses and existing debts. Pre-approval is not unconditional approval, since it usually depends on the property, the valuation and conditions being satisfied.
Release or restructure the equity before settlement
Depending on the lender, equity may be released through a loan split, top-up or refinance. Leave room for lender processing so funds are ready when settlement is due.
Keep the deposit, purchase loan and costs traceable
Keep the deposit, the purchase loan and the costs in clearly labelled accounts or loan splits. Clean records help your accountant later and show how much debt is tied to each purpose.
Which loan structures can be used to access equity?
Structures vary by lender and borrower, and none is automatically best. The security for a loan and the purpose of the borrowed funds are separate questions, which matters for tax when using equity to buy investment property.
Separate equity loan or loan split
A loan split is a new loan secured against your existing property and used for the purchase. The main advantage is that the loan purpose is easy to see. The caution is another loan to service, possibly with different terms.
Top-up or refinance
A top-up increases the existing loan, while a refinance replaces it, sometimes with a new lender. This can simplify repayments, but mixing borrowed deposit funds with existing home debt blurs loan purposes, and costs may apply.
Redraw and offset accounts
Redraw lets you access extra repayments you have already made, so it is not the same as a new equity loan. An offset account holds your own cash against the loan, and that cash is not borrowed equity. A broker should confirm lender rules, and a tax adviser should confirm how mixed-purpose use is treated.
What do lenders assess before approving the loan?
Does having equity mean you can borrow more? No. Lenders apply an equity gate and a serviceability gate, and how lenders view equity for investing shows both feed into approval. Either gate can stop the purchase, even when using equity to buy investment property looks sensible on paper.
Income, expenses, debts and credit history
- Borrower: income (business owners may need extra documents), living expenses and credit history.
- Existing portfolio: current loans, credit cards and other commitments.
Property valuation, LVR and asset type
- Security property: the lender's valuation and the LVR it allows.
- Proposed property: valuation, rent assumptions and whether it is residential or commercial.
- Lender policy: whether lenders mortgage insurance (LMI) applies and which property types the lender accepts.
Repayments if rent falls or interest rates rise
Lenders commonly build in buffers, so the repayments assessed may be higher than those you pay on day one. Ask your broker which buffers and rent assumptions apply to your application.
What costs and tax considerations should investors understand?
The true cost of using equity to buy investment property goes beyond the deposit. Amounts vary by state, territory, buyer type, property type and contract, so no national figure is given here.
Purchase and finance costs
- Transfer duty (stamp duty), set by the relevant state or territory revenue office
- Conveyancer or solicitor fees and contract review
- Valuation fees and building, pest or other inspections
- Loan application, settlement and discharge fees
- LMI, if the lender requires it
- Ongoing interest on the new borrowing
Interest tracing and mixed-purpose borrowing
Interest may be deductible only to the extent the borrowed funds are used to produce assessable income, subject to the ATO rules and the investor's circumstances. The Australian Taxation Office (ATO) explains ATO guidance on rental property interest and when private and investment purposes may need apportioning.
Refinancing or redrawing does not automatically make all interest investment-related. The use of the funds decides the treatment, not the property that secures the loan.
When professional tax advice is necessary
Mixed-purpose loans, redraw, trusts, companies and commercial GST all turn on detail. Speak to a registered tax adviser before you restructure, not after. Nothing here promises a tax benefit, and outcomes depend on individual circumstances.
What are the risks of using equity to invest?
Borrowing increases both potential gains and potential losses. That is the honest starting point for using equity to buy investment property.
Higher debt and repayment pressure
More debt means higher repayments, and Moneysmart's borrowing-to-invest guidance notes that income shortfalls and rate changes can strain them. A simple downside test helps: can you hold the property if rent falls, the valuation is lower or repayments increase?
Falling values, vacancies and valuation shortfalls
A vacancy removes rent while the loan keeps running. A falling value or a low lender valuation can raise the cash you must contribute, and in a worst case may force a sale at a poor time.
Cross-collateralisation and loss of flexibility
When one lender holds security over several properties under linked loans, a change to one loan can affect the others. Selling or refinancing one property may become harder, so ask whether each loan can stand on its own.
How does using equity for commercial property differ?
Can you use equity to buy commercial property? Potentially, but the financing and due diligence requirements depend on the asset, borrower and lender. Using equity to buy investment property in the commercial space means the asset's lease evidence is assessed alongside your own finances.
Office, retail and industrial assets require different evidence
An office, a retail shop and an industrial unit each have different demand drivers, tenant profiles and permitted-use limits. The table below shows where the evidence typically shifts from residential.
| Factor | Residential property | Commercial property |
|---|---|---|
| Income evidence | Rent appraisal and market comparison | Lease terms, tenant strength, weighted average lease expiry (WALE) |
| Valuation | Comparable sales | Often income and lease-based, so a weak lease can lower the value |
| Deposit and LVR | Lender policy | Lender policy by asset, lease and tenant; confirm with a commercial broker |
| Running costs | Rates, insurance, maintenance | Outgoings, with recovery depending on the lease |
| Tax | Transfer duty, land tax | GST may be relevant depending on the contract; confirm with your accountant |
Buyers Agency Australia's commercial property acquisition support is aimed at office, retail and industrial buyers who want this evidence tested before they commit.
Lease income, tenant strength, outgoings and vacancy
Test lease durability, not just the headline yield. A strong yield can look very different once you see how soon the lease ends and who is paying it.
- Lease term, options and review mechanisms
- Tenant strength and trading history
- Which outgoings the tenant recovers
- Vacancy and re-letting risk
- Permitted use and zoning
- Building condition
Commercial valuation, deposit and GST questions
Commercial valuations lean on income and lease evidence, so the valuation can land below the price. Deposit and LVR requirements are lender-specific, so ask a commercial broker instead of assuming a residential figure.
GST and ownership structure (company, trust or SMSF) are questions for your accountant and solicitor. SMSF acquisition is a specialist area, so do not assume personal home equity can be used inside an SMSF strategy.
What should I check before using equity to buy?
Before committing, run the plan through three gates. Ask your broker, accountant and buyers agent the questions that belong to each of them, and let none of them replace the others.
Finance readiness checklist
- Has a lender or broker confirmed usable equity on a current valuation?
- Does serviceability still pass once the new debt is added?
- How will the deposit and purchase costs be funded?
Property and portfolio fit checklist
- What role must this property play: income, growth or diversification?
- Does the asset meet your evidence threshold on rent, lease, condition and valuation?
- Does it suit your wider plan? How equity can build a portfolio is a later-stage sequencing question, separate from the release mechanics covered here.
Downside test before committing
If the plan fails on serviceability, cash buffer or due diligence, do not release equity simply because a property has been found. That stop rule protects both your home and your portfolio.
If you are still shaping your finance position, you can book a free strategy session to test the property brief and portfolio role before you commit.
How can a buyers agent support the acquisition?
What follows is Buyers Agency Australia's stated buyer-side approach, not an independent ranking, review or guarantee. It is also not financial, tax or lending advice for investors using equity to buy investment property.
Strategy before property selection
The brand describes a process that starts with planning, so the property brief reflects your finance limits, risk tolerance and portfolio role. Buyers Agency Australia presents Dragan Dimovski as a property expert with 20+ years of experience.
Research, due diligence, negotiation and settlement support
A buyers agent does not replace a mortgage broker, accountant, solicitor, valuer or financial adviser. The agent helps assess and acquire the property, while finance and tax professionals verify the borrowing and tax decisions.
The brand's stated process covers property research, due diligence coordination, negotiation and settlement support across residential investment and office, retail and industrial assets. Property selection is the step that connects a released equity amount to a completed purchase.
When Buyers Agency Australia may not be the right fit
The service may not suit you if you have not confirmed borrowing capacity, want personal financial advice or are seeking a guaranteed return. It is also a poor fit if you are not ready to complete independent legal, tax, finance and property due diligence.
Frequently asked questions about using equity to buy an investment property
Can I use equity in my home as a deposit for an investment property?
Potentially, if the lender approves the release and your overall borrowing remains serviceable. The equity is borrowed, and purchase costs still need funding.
How do I calculate usable equity?
A common illustration is the lender's allowable lending amount, based on valuation and LVR, less your loan balance. The lender's valuation and policy decide the actual result.
Does having equity guarantee investment property loan approval?
No. Lenders also assess income, expenses, debts, credit history, serviceability and the proposed property.
How much investment property can I buy with my equity?
It depends on usable equity, borrowing capacity, purchase costs and the lender's view of the property. There is no universal multiple to rely on.
Is a loan split better than redraw?
Neither is automatically better. Suitability depends on the lender, loan purpose and tax record-keeping, so ask a broker and a tax adviser.
What happens if the lender's valuation is lower than the purchase price?
A lower valuation can increase the funds you must contribute or force the finance structure to be reconsidered. Outcomes vary by lender.
Can I use equity to buy commercial property?
Potentially, but lending depends on the asset, lease, tenant, valuation, borrower position and lender policy. Office, retail and industrial each need different evidence.
Can I claim the interest on an equity release?
It depends on how the borrowed funds are used and whether the purpose can be traced. Check ATO guidance and ask a registered tax adviser.
Is using equity to invest risky?
Yes. It increases debt and can expose the property used as security if repayments cannot be maintained, especially with vacancy, rate or valuation shifts.
Should I speak to a buyers agent before releasing equity?
If you are confirming finance, a buyers agent can help test whether a property fits your strategy. They do not replace your broker, accountant or solicitor.
Next steps before releasing equity
Three gates keep using equity to buy investment property disciplined rather than hopeful.
- Confirm the finance gate: obtain a current valuation, usable-equity figure, serviceability assessment and proposed loan structure.
- Confirm the asset gate: choose a residential or commercial property that fits your documented strategy, evidence threshold and portfolio role.
- Confirm the downside gate: test repayments, vacancy, lower rent, valuation shortfall, maintenance and transaction costs before committing.
Once the three gates are clear, bring your finance position and property brief to a strategy session to map your next property move. A session like this is not personal financial advice or a loan approval service.
