A 20% deposit is the common benchmark for an Australian investment property because it produces an 80% loan-to-value ratio (LVR) and often avoids lenders mortgage insurance (LMI). Some lenders may consider a lower deposit, but the investor may face LMI, a tighter serviceability assessment, and higher total borrowing costs. The real target is the deposit plus transfer duty, conveyancing, inspections, lender costs, and a cash buffer. Your income, existing debts, expenses, property valuation, and loan structure all matter as much as the deposit itself.
You have saved a deposit or built equity in an existing property. The question keeping you up at night is whether that amount is actually enough to get through settlement and come out the other side in a sound financial position.
The word "deposit" adds to the confusion because it means different things at different stages of a purchase. It can refer to the amount you hand over with an offer, the equity contribution a lender requires, or the full cash position needed to complete the transaction. Blurring those three meanings together is one of the most common deposit-planning mistakes investors make.
This guide separates each of those concepts, explains the key lending rules that shape your practical target, and shows what the real cash requirement looks like through three illustrative scenarios. For investors connecting these numbers to a broader plan, Buyers Agency Australia investment guidance provides strategy-led support from suburb selection through to settlement.

How much deposit do you need for an investment property in Australia?
For most investment property loans in Australia, a 20% deposit is the most widely used benchmark because it targets an 80% LVR. At 80% LVR, many lenders do not require lenders mortgage insurance, and the borrowing assessment tends to be more straightforward. ASIC's MoneySmart guidance identifies a 20% deposit as a common savings goal for property buyers.
That 20% figure is a benchmark, not a universal legal requirement. Some lenders may consider a lower deposit for investment loans, but the trade-offs include LMI, stricter serviceability tests, and potentially higher interest rates. Others may require more than 20% depending on the borrower's profile, property type, and loan structure.
The most important distinction to grasp early is this: the deposit percentage your lender requires and the total cash you need at settlement are two very different numbers. A 20% deposit on a $700,000 property is $140,000. Add transfer duty, conveyancing, inspections, lender fees, and a cash buffer, and the actual cash requirement can be materially higher.
Why there is no single minimum deposit for every investor
The phrase "minimum deposit" sounds like a fixed rule. In practice, it is shaped by at least five different variables: lender policy, the borrower's financial profile, the property type, the loan structure, and the relevant state or territory's transaction costs.
Three concepts are frequently confused under the single word "deposit":
| Term | What it means | Why it matters |
|---|---|---|
| Contract deposit | The amount paid with an offer or at auction, usually 5% to 10% of the purchase price | Does not represent the lender's full equity requirement |
| Lender equity contribution | The full equity position the lender expects, typically measured by LVR | Determines whether LMI applies |
| Total settlement cash | Deposit plus transfer duty, conveyancing, inspections, lender costs, and buffer | The actual figure you need in your account |
A property valuation below the purchase price adds a further complication. If a lender values the property at less than what you agreed to pay, the LVR calculation uses the lower figure, which means you may need to contribute more cash to maintain the same LVR. A qualified mortgage broker can help you model these scenarios before you commit to a purchase.
The common deposit benchmarks for investment property loans
The table below sets out the four most commonly discussed deposit positions for investment property and the key trade-offs attached to each. All figures are illustrative and lender-specific. Verify any scenario with a current mortgage broker before relying on it.
| Deposit | Indicative LVR | Likely trade-off | What to verify |
|---|---|---|---|
| 5% | 95% | Not a standard investor pathway. The Australian Government 5% Deposit Scheme applies to eligible owner-occupiers only, not investment properties. Some specialist lenders may consider 95% LVR investor loans but at materially higher rates. | Confirm availability and pricing with a lender or broker. |
| 10% | 90% | May be considered by some lenders with LMI and stronger serviceability. Higher LMI cost. Stricter assessment is common. | Confirm lender policy and LMI cost before proceeding. |
| 20% | 80% | Common benchmark. Often avoids LMI. More lenders participate. | Verify that transaction costs and a cash buffer are funded separately. |
| More than 20% | Below 80% | Lower debt, lower repayments, stronger cash-flow resilience. Capital used for the deposit is unavailable for other investments or emergencies. | Assess opportunity cost against portfolio strategy. |
Can I buy an investment property with a 5% deposit?
In most practical scenarios, no. The Australian Government's 5% Deposit Scheme is available to eligible owner-occupiers, not investors purchasing a rental property. While a small number of specialist lenders offer 95% LVR investment loans, these typically come with higher interest rates and strict eligibility criteria. This is not a pathway most investors should plan around without detailed advice from a current mortgage broker.
Can I buy an investment property with a 10% deposit?
Some lenders may consider a 10% deposit for an investment loan, but it generally involves LMI, tighter serviceability scrutiny, and potentially a higher interest rate. Availability is lender-specific, and the LMI cost at a 90% LVR is considerably higher than at an 85% LVR. If a 10% deposit is all that is available, speak with a broker about whether the total acquisition cost still makes financial sense.
Why 20% is often used as the practical benchmark
A 20% deposit produces an 80% LVR, which is where many mainstream lenders draw the line for requiring LMI. Below 80% LVR, the lending assessment is typically smoother, and more lenders participate competitively. It is worth noting that 20% covers only the lender's equity requirement. Transfer duty, conveyancing, inspections, and other costs must be funded in addition to the deposit.
When a deposit larger than 20% may make sense
A larger deposit reduces borrowing, lowers monthly repayments, and can improve cash-flow resilience, which matters when vacancy periods or rate changes arise. The trade-off is opportunity cost: capital tied up in a single property is unavailable for other investments or as an emergency reserve. The right balance depends on your overall property investment strategy process and portfolio sequencing, not just the entry price.
What is the real cash amount needed at settlement?
This is where many first-time investors underestimate their cash requirement. The formula is straightforward:
Total cash target = Deposit + Transfer duty + Conveyancing + Inspections + Lender costs + Valuation fee + Insurance + Adjustments + Buyer-side fees + Emergency buffer
Which upfront costs should investors budget for?
Beyond the deposit, investors should budget for the following:
- Transfer duty (stamp duty): The most significant variable. Rates differ by state or territory, property value, property use, and buyer circumstances. In NSW, transfer duty is calculated on a sliding scale by Revenue NSW. In Victoria, the State Revenue Office Victoria publishes general rates that apply to investment purchases. Never apply one state's rate to another state.
- Conveyancing or solicitor fees: Usually $1,500 to $3,000, depending on complexity and location.
- Building and pest inspection: Typically $400 to $800.
- Lender application and valuation fees: Vary by lender and loan product.
- Landlord insurance: Often required before or at settlement.
- Adjustments at settlement: Council rates, water rates, and body corporate fees may be apportioned.
- Emergency buffer: A reserve to cover unexpected repairs, vacancy periods, or changes in repayment obligations.
For a property in NSW, transfer duty alone can add tens of thousands of dollars to the cash requirement. Check the Revenue NSW transfer duty calculator and the relevant revenue office in your target state before finalising a budget.
Why the contract deposit is not the same as the full lender deposit
When you sign a contract or win at auction, you typically pay a contract deposit of 5% to 10% of the purchase price. That amount is not the same as the equity the lender requires. The lender will assess the full LVR based on the accepted property valuation and the total loan amount. You need the remaining equity and all purchase costs funded by settlement day, not just the contract deposit.
How lenders assess your deposit and borrowing capacity
A large deposit does not guarantee loan approval. Lenders assess your entire financial position, and the borrowing capacity for investment property depends on several interconnected factors.
What does borrowing capacity have to do with your deposit?
Serviceability is the lender's test of whether you can afford the repayments. Under APRA's residential mortgage lending standards, authorised deposit-taking institutions (ADIs) must assess a borrower's ability to repay at the loan rate plus a buffer of at least 3 percentage points. As confirmed in APRA's May 2026 macroprudential update, that buffer remains at 3 percentage points. If your income and existing commitments do not support the repayments at the assessed rate, no deposit size will change that outcome.
It is also worth noting that APRA introduced debt-to-income (DTI) limits from February 2026, requiring ADIs to limit new mortgage lending with a DTI ratio of six or more to 20% of all new lending. This affects investors with significant existing debt and can reduce available borrowing even when a deposit is ready.
How rental income and existing debt affect the assessment
Lenders may include a portion of the expected rental income in the serviceability calculation, but they typically apply their own assessment assumptions rather than the full market rent figure. Existing debts, credit card limits (even unused ones), and living-expense estimates all reduce the amount a lender will approve. A mortgage broker can run a current serviceability calculation across multiple lenders before you begin searching for a property. This is a useful step toward understanding how to invest in property in Australia with a realistic finance foundation.
Can I use equity instead of cash for the deposit?
Yes, usable equity in an existing property can contribute to an investment purchase. But equity is a secured borrowing mechanism, not free money. The lender assesses how much of your existing property value can be borrowed against, subject to valuation and serviceability.
A simple usable equity formula
The following is an illustrative estimate, not a lending approval:
Indicative usable equity = (Accepted property value x lender's LVR limit) – Existing loan balance
Example (illustrative only, not a lender approval):
- Accepted property value: $900,000
- Lender's LVR limit: 80%
- Maximum borrowable: $720,000
- Existing loan balance: $500,000
- Indicative usable equity: $220,000
That $220,000 could be accessed through a loan top-up or a separate equity loan, subject to valuation and full serviceability assessment. As Westpac's investment property deposit guidance notes, a lender typically calculates usable equity based on borrowing against up to 80% of a property's value, minus the existing loan balance.
What can go wrong when equity funds the deposit?
Several risks deserve attention before accessing equity:
- Valuation shortfall: The lender's accepted value may be lower than your estimate, reducing available equity.
- Higher total debt: You now carry two loan facilities. Repayment pressure increases on both properties.
- Cross-collateralisation: Some lenders link both properties as security. This limits your flexibility to sell, refinance, or restructure later.
- Interest-rate risk: Rising rates affect both loans simultaneously.
- No cash buffer: Using every dollar of equity for the deposit leaves nothing for vacancy, repairs, or emergencies.
Discussing loan structure with a mortgage broker before accessing equity protects both your existing property and the new investment. Reviewing property investment fundamentals before committing to equity access helps frame the decision within a broader portfolio context.
What is lenders mortgage insurance and when might it apply?
Lenders mortgage insurance (LMI) is an insurance premium paid by the borrower to protect the lender if the borrower defaults and the property sale does not cover the outstanding loan. LMI does not protect the borrower.
LMI generally applies when a borrower's LVR exceeds the lender's preferred threshold, most commonly above 80%. The premium depends on the lender, the LVR, the loan amount, and the borrower's profile. Investment property LMI premiums are typically higher than owner-occupier equivalents.
Do not plan around a specific LMI dollar amount without running a current calculation through a lender or insurer, as premiums vary significantly between lenders and LVR bands. The key strategic question is whether paying LMI to enter the market earlier makes sense compared to waiting to accumulate a larger deposit. That decision depends on your cash-flow position, market timing assessment, and portfolio plan, not a universal rule. Avoiding LMI is not always the correct call if waiting materially delays a sound investment or depletes your emergency reserve.
Worked deposit examples for different Australian investor scenarios
All figures below are illustrative only. They are not lender approvals, quotations, or recommendations. Transaction costs vary by state, territory, lender, and individual circumstances.
Scenario 1: First-time investor using cash savings
| Item | Illustrative figure |
|---|---|
| Target purchase price | $650,000 |
| Deposit (20%) | $130,000 |
| Loan amount (80% LVR) | $520,000 |
| Transfer duty (state-dependent, estimate only) | Check relevant state revenue office |
| Conveyancing and inspections | Approximately $2,500 to $4,000 |
| Lender fees and valuation | Approximately $500 to $1,500 |
| Emergency buffer (recommended) | $15,000 to $20,000 |
| Indicative total cash target | $150,000 to $160,000+ |
Assumption: The investor holds the deposit in cash savings, the lender values the property at the purchase price, and no LMI applies. Transfer duty must be calculated using the relevant state or territory revenue office for the target purchase location.
Scenario 2: Existing owner using usable equity
| Item | Illustrative figure |
|---|---|
| Existing property accepted value | $850,000 |
| Existing loan balance | $450,000 |
| Maximum borrowable at 80% LVR | $680,000 |
| Indicative usable equity | $230,000 |
| Target investment property price | $700,000 |
| Deposit funded from equity | $140,000 (20%) |
| Remaining equity after deposit | $90,000 (available for costs and buffer) |
Assumption: The lender's accepted valuation matches the estimate, serviceability is confirmed for both facilities, and no cross-collateralisation is used. All figures are indicative. A mortgage broker must verify the actual accessible equity and loan structure.
Scenario 3: Growth-stage investor protecting future borrowing capacity
An investor already holding one or two properties may technically have enough equity or cash for a third purchase. The decision is rarely that straightforward. Using every available dollar of deposit leaves no room for vacancy periods, maintenance costs, or a rate increase across the portfolio.
A 25% deposit instead of 20% means a lower loan balance, smaller repayments, and a stronger position for the next acquisition. The investor who enters a third purchase over-leveraged can find that serviceability limits on a future purchase arrive sooner than expected. This connects directly to property investment mistakes to avoid: focusing only on the entry price rather than the cumulative repayment burden across the portfolio.
How to set a realistic deposit target before you buy
A useful deposit target answers three questions: how much will the lender accept, what does it cost to get through settlement, and what is left over to hold the property safely? Work through these seven steps before signing anything:
- Confirm borrowing capacity first. Speak with a current mortgage broker and obtain a conditional pre-approval so you know the lender's position before you commit to a price range.
- Set a realistic property price range. Do not assume the largest loan you could theoretically obtain is the right starting point.
- Calculate transfer duty for your target state or territory. Use the official state or territory revenue office calculator, not an estimate from a property listing.
- Add all purchase costs. Include conveyancing, inspections, lender fees, valuation, landlord insurance, and any body corporate adjustments.
- Model repayments conservatively. Because APRA requires ADIs to assess repayments at the loan rate plus a 3-percentage-point buffer, model your cash flow at a higher-than-current rate to check whether the investment is still viable.
- Reserve an emergency and vacancy buffer. Most experienced investors hold a buffer covering at least three to six months of loan repayments and anticipated maintenance costs.
- Confirm alignment with your investment strategy. The deposit target should reflect the property type, location, and hold period that fits the wider portfolio plan, not just the maximum affordable price.

How Buyers Agency Australia can fit into deposit planning
Australia-wide buyer-side support from Buyers Agency Australia centres on connecting an investor's available capital to the right market, property type, and acquisition strategy. Once the finance framework is established with a mortgage broker, the buyers agent role shifts to identifying suitable assets, assessing risk, negotiating terms, and supporting the buyer through due diligence and settlement.
Dragan Dimovski, a property expert with more than 20 years of experience, understands that a deposit figure alone does not make a property purchase sound. The selection of the asset, the structure of the acquisition, and the fit with the investor's portfolio sequencing determine whether the deposit is deployed well.
Buyers Agency Australia's service details were checked in August 2026. The service covers strategy, data-led suburb selection, property assessment, negotiation, and support from planning through to settlement.
When this is not the right fit
A buyers agent is not a replacement for a mortgage broker, accountant, tax adviser, solicitor, or conveyancer. Readers who do not yet have a confirmed finance position, or who need guidance on negative gearing, ownership structure, SMSF investment, CGT, or contract terms, should resolve those questions with the relevant licensed or registered professional first. A buyers agent adds the most value when the finance framework is established and the focus moves to identifying and securing the right property.

Frequently asked questions about investment property deposits
How much deposit do I need for an investment property in Australia?
A 20% deposit is the most commonly used benchmark, producing an 80% LVR and often avoiding LMI. The practical cash target is higher once transfer duty, conveyancing, inspections, and a buffer are included.
Can I buy an investment property with a 10% deposit?
Some lenders may consider a 10% deposit for an investment loan, typically with LMI and a stricter serviceability assessment. Availability and LMI cost are lender-specific. Confirm the full acquisition cost with a mortgage broker.
Can I buy an investment property with a 5% deposit?
The Australian Government's 5% Deposit Scheme is for eligible owner-occupiers and does not apply to investment properties. A 5% deposit is not a standard investor pathway with mainstream lenders.
Is 20% enough once stamp duty and buying costs are included?
No, not on its own. A 20% deposit covers only the lender's equity requirement. Transfer duty, conveyancing, inspections, lender fees, and a buffer add to the cash requirement and must be funded separately.
Can I use equity instead of cash for the deposit?
Yes, subject to lender valuation and full serviceability assessment for both properties. Usable equity is calculated as a proportion of your existing property value minus the outstanding loan balance. It is not free money and carries valuation, repayment, and cross-collateralisation risks.
Does LMI apply to investment property loans?
LMI may apply when an investment loan's LVR exceeds the lender's preferred threshold, typically above 80%. LMI protects the lender, not the borrower, and the premium for investment loans differs from owner-occupier equivalents. Confirm the cost with a current lender or insurer calculation.
Can gifted money be used as an investment property deposit?
Some lenders may accept gifted funds as part of a deposit, but conditions apply and lender policies differ. You should disclose the source of funds to your lender and confirm policy with a current mortgage broker before relying on gifted money as your deposit.
Can I use superannuation to buy an investment property?
Generally, superannuation cannot be accessed directly for an investment property deposit outside of a self-managed super fund (SMSF). SMSF property investment is subject to strict restrictions under current ATO guidance on SMSF investing. Specialist SMSF advice from a registered adviser is required before proceeding.
Does negative gearing help me fund the deposit?
No. Negative gearing explained for investors refers to a tax treatment applied to rental losses, not an upfront cash source. It may reduce your tax liability over time but does not create deposit cash. Consult a registered tax adviser for advice specific to your circumstances.
Does buying interstate change how much deposit I need?
The deposit policy is set by the lender and is not state-specific. However, transfer duty, transaction costs, and any state-based taxes or concessions vary significantly by state or territory and materially affect total cash required at settlement. Check the revenue office for your target state before finalising a budget.
Your next-step deposit plan
Three questions clarify where you stand before you proceed:
- How much cash or usable equity do you have confirmed? Not estimated, but verified with a lender or broker against a current valuation.
- What will the lender support? Serviceability, DTI ratios, and lender-specific investment policies all shape the approved loan amount independently of your deposit size.
- What acquisition strategy protects the portfolio? The deposit target should reflect the property type, hold strategy, and total cost of ownership, not just the purchase price.
If the answer to any of those questions is unclear, that is the right place to start. A clear finance picture before property selection prevents the common mistake of choosing an asset simply because it sits within a raw price ceiling.
