You may be able to buy your next investment property using usable equity rather than a separate cash deposit, but there is no single equity figure that suits every investor. A practical estimate starts with the lender-supported value of your existing property, less current debt, then adds the deposit and purchase costs for the next property. The lender must still approve the total borrowing based on income, expenses, existing debt, property valuation and serviceability. Equity is one gate in a broader acquisition decision, not an automatic green light.
If you own a property that has grown in value, it is natural to wonder whether that growth can fund your next purchase. The real calculation, though, has four moving parts: usable equity, the deposit required, buying costs, and borrowing capacity. Getting one right without the others can still leave the deal short.
This guide walks through each part clearly, including how the calculation changes when the next asset is office, retail or industrial property rather than a standard residential investment. It is not personal financial, lending, legal or tax advice. Verify your own position with a mortgage broker, lender, accountant, solicitor or conveyancer before acting. For strategy-led property investment advice, the team at Buyers Agency Australia works with investors at both the residential and commercial end of the market.
What equity means when buying your next investment property
Home equity is the difference between your property's current market value and the amount still owed on the mortgage. If the property is worth $900,000 and the outstanding loan is $500,000, total equity is $400,000. That figure sounds useful, but it does not reflect what a lender will actually allow you to access.
Usable equity is the portion a lender may permit you to borrow against, after accounting for existing debt and its own loan-to-value ratio (LVR) policy. Most lenders use a planning assumption of 80% of the property's accepted valuation as the upper limit before requiring Lenders Mortgage Insurance (LMI). LMI protects the lender, not the borrower, if the loan defaults.
Borrowing capacity is a separate question entirely. It measures whether you can service the total proposed debt, assessed against income, living expenses, existing loans, credit limits, dependants and a lender-applied interest-rate buffer.
| Concept | What it measures | Key input |
|---|---|---|
| Total equity | Property value minus outstanding debt | Current market value and loan balance |
| Usable equity | Portion the lender may allow access to | Lender LVR policy and bank valuation |
| Borrowing capacity | Ability to service total proposed debt | Income, expenses, existing commitments, buffer |
| LVR | Loan as a percentage of property value | Loan amount divided by lender's accepted valuation |
According to ASIC Moneysmart, LVR is calculated by dividing the loan amount by the asset value and expressing the result as a percentage. A higher LVR means a larger proportion of the property is funded by the lender, which typically carries more risk and may trigger LMI.
How much equity do you need to buy an investment property?
There is no fixed equity amount because the requirement depends on the purchase price, the deposit strategy, transaction costs, lender policy and your borrowing capacity. The question is better framed as: how much does the total funding requirement add up to, and can usable equity cover it?
A common planning scenario targets an 80% LVR, which requires a 20% deposit. At that level, most lenders do not require LMI, though eligibility criteria and lender policy vary. ANZ notes that deposit size, LVR, LMI, income, expenses, interest rates and other factors all affect investment-property borrowing outcomes.
Lower-deposit options may be available from some lenders, but they often involve LMI, stricter credit criteria and higher effective borrowing costs. That is a finance conversation to have with a mortgage broker, not a decision to make based on a single number.
Critically, equity must cover more than the deposit. If the purchase also requires transfer duty (commonly called stamp duty), legal costs, inspections, valuation fees and a cash buffer, those amounts need to come from somewhere, whether equity, savings or a combination.
| Scenario | Purchase price | 80% LVR deposit | Estimated costs (illustrative) | Total funding required |
|---|---|---|---|---|
| Scenario A | $600,000 | $120,000 | ~$25,000 | ~$145,000 |
| Scenario B | $900,000 | $180,000 | ~$35,000 | ~$215,000 |
Illustrative example only. Actual costs vary by state, asset type, ownership structure and transaction details. Verify with a solicitor and the relevant state revenue office.
Can you have enough equity but still be unable to buy?
Yes, and this is one of the most common sources of confusion for investors. Equity addresses the security side of a lender's decision. Borrowing capacity addresses the repayment side. Both must pass.
A lender may determine you have sufficient usable equity to provide a deposit, but still decline the loan if the serviceability assessment falls short. Common reasons include:
- Existing investment or personal loans that reduce available income
- High credit card limits, even if balances are low
- Variable or self-employed income assessed conservatively by the lender
- Dependants or significant living expenses
- Rental income from existing properties shaded by the lender (often to 70% to 80% of the actual rent)
- The interest-rate buffer applied under APRA's current macroprudential settings
APRA confirmed in May 2026 that the mortgage serviceability buffer remains at 3 percentage points, meaning lenders assess new borrowers at the actual loan rate plus 3% to test repayment capacity under a higher-rate scenario. Individual lenders implement the buffer in their own assessment models, so outcomes vary.
A lower borrowing capacity is not necessarily the end of an investment plan. It may mean adjusting the purchase price, asset type, loan structure or timing. A mortgage broker can assess which lenders are most suited to your income and debt profile.
How to calculate usable equity
The standard planning formula is:
Usable equity = (current property value x lender's LVR limit) – existing secured debt
Using 80% as an illustrative planning assumption:
- Current property value: $900,000
- 80% planning limit: $720,000
- Existing loan balance: $500,000
- Estimated usable equity: $220,000
Illustrative example only. The lender's accepted valuation, which may differ from the contract price or an agent's estimate, is the figure used in the actual calculation.
This $220,000 is not cash sitting in an account. Accessing it creates additional debt secured against the existing property. The lender will need to approve the increased borrowing, assess the property through its own valuation process and confirm your serviceability position. As Westpac notes, usable equity is assessed using current property value, outstanding debt, the lender's own valuation and lender-specific criteria.
80% is a common planning assumption, not a universal rule. Some lenders apply different LVR thresholds depending on the property type, postcode, asset class and ownership structure. The bank's accepted valuation can also come in below your expectation, particularly in markets where comparable sales are limited or property condition is a factor.
What does loan-to-value ratio mean in Australia?
LVR is the ratio of the loan amount to the lender's accepted property valuation, expressed as a percentage. The formula is:
LVR = (loan amount / property value) x 100
For example, a $400,000 loan against a $500,000 valuation gives an LVR of 80%. A $450,000 loan against the same valuation gives an LVR of 90%, which most lenders treat differently in terms of pricing, LMI requirements and approval criteria.
The key detail is that the denominator is the lender's accepted valuation, not the purchase price or an agent's market appraisal. Those figures can differ, sometimes materially, which affects how much usable equity the lender recognises.
How equity can fund the deposit and purchase costs
Released equity does not appear in a separate account automatically. A lender can structure access to equity in several ways, including a loan top-up on an existing mortgage, a separate loan split under the same lender, or a full refinance. Each approach has different implications for loan structure, interest treatment and flexibility.
The ATO notes that deductibility of interest depends on the use of the borrowed funds, and mixed private and income-producing purposes require accurate apportionment. This means the structure of how equity is drawn can affect tax treatment. An accountant should be involved in that decision.
A mortgage broker can help identify which structure suits your position, lender and objectives. No single approach is right for every investor. Cross-collateralisation, for instance, where an existing property is used as security for both loans, gives the lender more control over both assets during refinancing or sale. A separate loan split may preserve more flexibility for future decisions. The appropriate choice depends on your circumstances.
How much equity do you need for a $600,000 investment property?
Using an illustrative 80% LVR scenario:
- Purchase price: $600,000
- 20% deposit required: $120,000
- Illustrative purchase costs (transfer duty, legal fees, inspections, valuation, lender costs): approximately $25,000
- Total equity or cash required before settlement buffer: approximately $145,000
This is an illustrative example only and is not a client case study or verified outcome. Transfer duty (stamp duty) rates vary by state, territory, purchase price, ownership structure and whether the asset is residential or commercial. A solicitor and the relevant state revenue office should be consulted for actual cost estimates.
The same $145,000 of usable equity could support a higher purchase price if a lower LVR is acceptable to the lender, or a lower purchase price if costs are higher than assumed. The equity amount alone does not determine which property is suitable. Borrowing capacity, cash buffer, property quality and portfolio strategy all matter equally.
For property investment planning support that connects the finance position to portfolio strategy, Buyers Agency Australia's process begins with understanding goals before any property is sourced.
Why borrowing capacity matters as much as equity
Equity is a security measure. Borrowing capacity is a repayment test. They answer different questions, and both must be satisfied before a lender approves an investment loan.
Lenders assess borrowing capacity by looking at gross and net income (including how much rental income they are prepared to count), living expenses under their own benchmarks, all existing loan repayments, credit card limits, and the stress-tested repayment at the current rate plus the APRA-mandated buffer. APRA confirmed in May 2026 that the 3 percentage-point mortgage serviceability buffer remains in place for authorised deposit-taking institutions.
| Factor | Equity test | Borrowing capacity test |
|---|---|---|
| Property valuation | Central (sets the accessible amount) | Indirectly relevant (affects LVR and debt level) |
| Income and expenses | Not directly assessed | Core of the lender's calculation |
| Existing loans | Reduces usable equity indirectly | Reduces available borrowing directly |
| Interest-rate buffer | Not applied | Applied at rate plus 3 percentage points |
| Rental income | Not relevant | Partially counted, often at 70-80% of actual rent |
If you are speaking with a mortgage broker, useful questions to ask include: which income sources are counted in full, how rental income on existing and proposed properties is shaded, what outstanding debts are included, which assessment rate is used, and how adding another loan affects future borrowing for subsequent purchases.
If the borrowing capacity gap is the constraint rather than equity, time spent reducing high-interest consumer debt, restructuring credit limits or waiting for income to strengthen can change the outcome. This is a finance planning decision, not purely a property selection one. Book a free strategy session to understand how your finance position and property goals connect before committing to a next move.
Costs to include beyond the investment property deposit
The deposit is the largest line item, but far from the only one. Failing to account for the full funding requirement is a common planning error that can catch investors short at or after settlement.
| Cost item | Why it matters | Who to verify with |
|---|---|---|
| Transfer duty (stamp duty) | Varies by state, price, ownership structure and asset type | State or territory revenue office |
| Conveyancing and legal fees | Contract review, title search, settlement | Licensed solicitor or conveyancer |
| Building and pest inspection | Condition risks before purchase | Qualified inspector |
| Property valuation (lender) | Bank may require an independent valuation | Lender or registered valuer |
| Lender establishment fees | Loan setup and application costs | Lender |
| Lenders Mortgage Insurance (if LVR exceeds threshold) | Protects the lender if the loan defaults | Lender |
| Landlord insurance | Income and liability protection | Insurance provider |
| Land tax (where applicable) | Ongoing state-based obligation | State revenue office and accountant |
| Strata or body corporate fees | Applies to units and some commercial assets | Body corporate or strata manager |
| Commercial due diligence costs | Lease review, building reports, planning checks, valuation | Solicitor, building consultant, registered valuer |
| Post-settlement cash buffer | Vacancy, urgent repairs, rate changes | Personal finance assessment |

Risks of using equity to expand a property portfolio
Using equity to fund an investment purchase increases the total debt secured against your existing property. ASIC Moneysmart notes that borrowing to invest can amplify gains and losses, and that repayments remain due even when an investment falls in value or income stops.
The key risks to consider include:
- Higher total debt and repayment pressure: Two loans mean two sets of repayments. A vacancy period on the investment property, or an interest-rate movement, can create cash-flow strain.
- Valuation risk: If either property falls in value, LVR increases. The lender may require additional security or limit future borrowing.
- Vacancy and repair costs: Rental interruption, maintenance needs or a capital expenditure requirement on the investment property can arrive at any time.
- Refinancing risk: Cross-collateralising properties may limit your ability to refinance or sell one asset independently. Ask how each property can be sold or restructured without affecting the other.
- Concentration risk: A portfolio concentrated in one asset class, geography or tenant type is more exposed to a single market event.
- Interest-rate changes: Even modest rate movements on a larger total loan can noticeably shift monthly repayment amounts.
A useful downside stress test before committing: what happens if the investment property is vacant for three months, interest rates move, or the bank valuation on either property comes in below expectations? If the answer creates significant financial pressure, the timing or asset selection may need reconsideration.
The ATO's guidance on rental properties clarifies that interest deductibility depends on loan purpose, and mixed private and income-producing use requires careful apportionment. Involve your accountant before finalising any loan structure.
How commercial property changes the equity conversation
For investors considering office, retail or industrial assets rather than residential investment property, the equity and lending conversation is materially different. Commercial lending does not follow a single standard. Lenders assess the quality of the income-producing asset alongside the borrower's position.
Factors that may influence a commercial lending assessment include the executed lease term and options, tenant covenant strength, rent review mechanisms, recoverable outgoings, vacancy history, building condition, zoning, planning use, interest coverage and ownership structure. An LVR threshold on a commercial product from one lender does not represent a universal industry rule.
| Feature | Residential investment property | Commercial property (office/retail/industrial) |
|---|---|---|
| Typical LVR planning range | Often to 80% for standard assets | Varies by lender, asset type and lease quality |
| Valuation basis | Comparable sales | Capitalised income, direct comparison, cost approach |
| Lease and tenant risk | Residential tenancy legislation | Commercial lease terms, tenant covenant, vacancy risk |
| LMI availability | Common for higher LVR | Generally not available; higher equity often required |
| Due diligence scope | Building, pest, strata | Lease, outgoings, building, planning, environmental, title |
| Finance assessment | Serviceability, income, expenses | Often includes interest coverage ratio, lease income |
For commercial property buying support covering office, retail and industrial acquisitions, Buyers Agency Australia's commercial service works with investors and SMSF trustees at this end of the market.
Headline yield on a commercial property is incomplete without lease, tenant, outgoings and vacancy analysis. A high yield on paper can reflect a short lease, an uncertain tenant or an asset with significant capital expenditure risk. The equity question and the asset quality question must be answered together.
For a detailed approach to evaluating commercial assets before committing funds, the commercial property acquisition guide covers the broader acquisition process.
What should you check before using equity for commercial property?
Commercial acquisitions require a broader due-diligence process than a residential purchase. Each item below should be verified through qualified professionals, not only through the listing or agent representations.
- Lease documentation: Obtain the full executed lease, including all variations and rental schedules. Check the remaining term, options to renew, rent review mechanism and any incentive arrangements.
- Rent ledger and arrears: Confirm that rent has been paid on time and that no arrears or disputes are outstanding.
- Tenant covenant: Assess the financial strength and operating history of the tenant. A long lease from a weak tenant carries more risk than it may appear.
- Recoverable outgoings: Understand which expenses are passed to the tenant and which remain with the owner. These affect net yield significantly.
- Title and zoning: Confirm the permitted use, any encumbrances, easements, covenants or planning overlays on the title.
- Building condition: Commission an independent building inspection. Older commercial assets can carry significant deferred maintenance, asbestos or environmental concerns.
- Lender and finance structure: Speak to a commercial finance broker about LVR thresholds, interest coverage requirements and how the lease quality affects lending eligibility.
- Valuation: Obtain an independent registered valuer's report. The lender will require their own valuation, which may differ from the asking price.
The commercial property due diligence checklist from Buyers Agency Australia provides further detail on each verification step.
A practical checklist before using equity
Before committing to an equity release and the next purchase, work through these three gates. If any gate is unresolved, pause and address it with the relevant professional before proceeding.
Finance gate
- Has a lender or mortgage broker confirmed the bank's accepted valuation of your existing property?
- What is the current loan balance, and how much usable equity does the lender calculate?
- What LVR does the proposed loan require, and does that require LMI?
- What is your assessed borrowing capacity after existing commitments and the serviceability buffer?
- What costs must be funded beyond the deposit, including duty, legal, inspections and valuation?
- What cash buffer will remain after settlement for vacancy, repairs and rate movements?
Strategy gate
- What role does the next property play in the portfolio: income, growth, commercial yield or diversification?
- Does the asset type (residential, office, retail or industrial) match your risk tolerance, time horizon and management capacity?
- Is the finance and asset combination one you could sustain through a six-month vacancy or an interest-rate increase?
- Have you read through how to build a property investment strategy so the next purchase fits a longer-term plan?
Professional advice gate
- Has a mortgage broker assessed the most appropriate lender and loan structure?
- Has an accountant reviewed loan-purpose tracing and the tax treatment of interest?
- Has a solicitor or conveyancer reviewed the proposed contract and costs?
- For commercial assets, has a registered valuer, building consultant and commercial finance broker been engaged?
Assuming all three gates are clear, the decision framework at the end of this guide covers the final steps.

How Buyers Agency Australia can help plan the next purchase
Buyers Agency Australia positions its process around portfolio strategy before property search. The stated approach begins with understanding the investor's goals, finance position and risk parameters, then identifying assets that serve a clear portfolio role rather than searching first and justifying later.
Dragan Dimovski, a property expert with 20+ years of experience, leads the advisory side of the business. The stated service scope includes portfolio planning, data-led property selection, buyer-side representation, sourcing of on-market and off-market opportunities, due-diligence coordination, negotiation and settlement support.
For investors looking at commercial acquisitions, including office, retail and industrial assets, the commercial acquisition strategy service extends the same buyer-side approach to commercial assets, including working with SMSF trustees and sophisticated investors navigating lease, yield and tenant quality decisions.
Important boundaries to understand: a buyers agent may help assess portfolio fit, source and negotiate property, and coordinate due diligence, but does not replace a lender, mortgage broker, accountant, solicitor, registered valuer, financial adviser or building consultant. Each professional plays a distinct role in the acquisition process.
When a buyers agent may not be necessary: An experienced investor with a defined strategy, verified finance, strong market knowledge and the time to manage sourcing, due diligence and negotiation independently may not require full-service buyer representation. The decision depends on complexity, capacity and how much time and expertise the investor brings.
Buyers Agency Australia service details were checked on official pages in September 2026. Confirm current scope and availability before engaging.
Frequently asked questions about equity and investment property
How much equity do I need to buy an investment property?
There is no fixed equity amount because the requirement depends on the purchase price, deposit, costs, lender policy and borrowing capacity. A practical estimate requires all four figures before a meaningful number can be given.
Can I use home equity as the deposit for an investment property?
You may be able to use released equity as part or all of the deposit, subject to lender approval and serviceability. The structure of that release, whether a top-up, split or refinance, should be discussed with a mortgage broker.
What is usable equity?
Usable equity is the portion of your property's value that a lender may allow you to borrow against after considering existing debt and its LVR policy. It is not the same as your total equity figure.
Is usable equity the same as borrowing capacity?
No. Usable equity relates mainly to available security, while borrowing capacity relates to your ability to repay the proposed debt. Both must be satisfied for a lender to approve an investment loan.
Do I need a 20% deposit for an investment property?
A 20% deposit is a common planning scenario, but lender requirements and lower-deposit options vary and may involve LMI. The right deposit level depends on lender policy and your finance position.
Can equity pay stamp duty and other purchase costs?
Released equity may be used toward eligible purchase costs, but the lender, transaction structure and available borrowing determine what is possible. Verify with your lender and accountant.
Can I use equity to buy commercial property?
You may be able to use equity toward a commercial purchase, but commercial lending can assess the lease, tenant income, valuation, asset type and ownership structure differently from residential lending.
What are the risks of using equity to invest?
The main risk is that using equity increases total debt and repayment pressure, even if the new property falls in value or rental income stops. Vacancy, repair costs, interest-rate changes and valuation risk all remain with the borrower.
Should I speak to a mortgage broker or a buyers agent first?
A mortgage broker or lender can help assess finance capacity, while a buyers agent can help assess property strategy, selection and acquisition. Both roles are distinct and often both are relevant.
Can Buyers Agency Australia help plan my next investment purchase?
Buyers Agency Australia states that its process begins with strategy and property selection before sourcing and acquisition support, covering both residential and commercial asset types.
Your next-step decision framework
Before moving from equity planning to a purchase decision, three gates should all be clear.
Gate 1 – Usable equity: Has the lender confirmed the accepted valuation of your existing property, the current loan balance, and the accessible equity amount under its policy? Does that amount cover the deposit, costs and a retained cash buffer?
Gate 2 – Borrowing capacity: Can you service the total proposed debt under the lender's assessment rate, the APRA serviceability buffer, and a realistic downside scenario involving vacancy or a rate movement?
Gate 3 – Property fit: Does the next residential or commercial asset serve a clear role in the portfolio after accounting for costs, risks, lease quality (for commercial), due diligence findings and professional advice?
Equity can create an opportunity, but it does not make a property suitable or guarantee an investment result. The usable equity number is the starting point, not the destination.
