A 20% deposit is the usual planning benchmark for an investment property in Australia, because it equals an 80% LVR and may help avoid LMI. It is not a universal minimum, and some lender policies may allow less. Whatever you put down, budget extra for transfer duty, conveyancing, inspections, lender costs and an accessible cash reserve.
You have saved a solid amount, or built some equity in your home, and now you are wondering if it is enough. Then the extras show up: duty, legal fees, inspections, lender costs. The figure you thought was your deposit suddenly looks smaller.
Here is the catch. Your investment property deposit is only one input. Price, LVR, LMI, borrowing capacity, state-based costs and cash reserves all shape the real target.
This guide is an Australia-wide planning framework from Buyers Agency Australia's strategy-led property investing team, built on regulator, consumer-finance and tax sources. It is general information only, not personal financial, lending, tax or legal advice. Confirm your position with a qualified lender, mortgage broker, accountant, solicitor or conveyancer.
What deposit do you realistically need for an investment property in Australia?
Plan around 20% of the purchase price, plus costs. That is the rough guide in ASIC Moneysmart's home loan guidance, but it is a benchmark rather than a rule. The amount a lender asks for depends on its policy, your borrower profile and the property itself.
Loan-to-Value Ratio (LVR) is the loan amount divided by the asset value, as set out in ASIC Moneysmart's LVR definition. Lenders Mortgage Insurance (LMI) usually applies when you borrow more than 80% of the property value, and it protects the lender, not you. Whether it applies to your loan is subject to lender policy and loan structure.
The deposit a lender expects can shift with:
- the lender's policy and risk appetite
- your income, debts and credit history
- the property type, location and valuation
- the loan structure and purpose
The 20% deposit benchmark and an 80% LVR
The arithmetic is simple, and worth keeping in view:
- LVR = loan amount divided by property value
- Deposit = purchase price minus loan amount
- A 20% deposit = an 80% LVR
On an illustrative $500,000 purchase, a $100,000 deposit leaves a $400,000 loan. Staying at or below 80% may help you avoid LMI, though the outcome is lender-specific.
Can a lower deposit be possible?
Sometimes. Some lender policies may permit a lower investment property loan deposit, but approval, LMI, valuation and serviceability all need confirming first. Without a named lender and a current policy, treat any figure below 20% as a possibility to test, not a promise.
What is the difference between a minimum deposit and a recommended deposit?
A minimum deposit is the least a lender may accept. A recommended deposit suits your debt tolerance, liquidity and portfolio plan, and the two are rarely identical. Your recommended investment property deposit is a planning decision, not just an approval threshold.
| Factor | Lower deposit pathway | 20% benchmark |
|---|---|---|
| Upfront cash | Less committed at purchase | More committed at purchase |
| LVR | Higher, for example 90% | About 80% |
| LMI | Possible, subject to lender policy | May be avoided at or below 80% LVR |
| Debt | Larger loan, higher repayments | Smaller loan |
| Liquidity | More cash may remain for reserves | Less spare cash if savings are fully used |
Lower deposit, higher LVR and possible LMI
A smaller deposit means a larger loan, so repayments become more sensitive to rate changes and vacancy. LMI may add to the cost, and you start with less equity in the property. The upside is that more cash may stay available for reserves.
Saving longer versus buying sooner with LMI is a trade-off with no universal answer. It turns on your cash flow, goals and the specific property, not on guessing market timing.
Larger deposit, lower debt and more cash committed
A bigger deposit reduces the amount borrowed and may avoid LMI. But if it drains every dollar of savings, you may have little left for repairs, vacancy or a rate rise. Debt is not the only risk; liquidity matters too.
Can you use equity from your existing home instead of cash?
Yes, potentially, but usable equity is not cash and it does not guarantee approval. Using equity to buy investment property can reduce the savings you need, yet the lender still assesses the whole application. For the wider portfolio angle, see this guide to using equity to build a portfolio.
Total equity versus usable equity
Total equity is your home's value minus the loan balance. Usable equity is the portion a lender will actually let you borrow against, after its own valuation and policy limits. Do not rely on an online estimate; a formal valuation and lender confirmation are the reliable guide.
Why valuation and borrowing capacity still matter
A lender may require a formal valuation, and it will still assess your income, expenses, existing debts and the proposed purchase. If its accepted value comes in lower than you expected, usable equity may shrink, and you may need more cash or a lower purchase price.
Using your home as security also raises the stakes, because your home is exposed if repayments cannot be met. Moneysmart's warning about borrowing to invest is worth reading before you commit.
What costs come on top of the investment property deposit?
The deposit is not the same as the total funds you need. ASIC Moneysmart's list of buying costs includes stamp duty, conveyancing, legal costs, search fees, pest reports and building reports. Duty and several other costs vary by state or territory, property value and buyer status.
Three numbers are easy to blur together:
- Contract deposit: the amount paid under the purchase contract, which varies by state and contract terms.
- Loan deposit or equity contribution: the part of the price you fund rather than borrow.
- Total funds required: everything needed to complete and safely hold the property.
Ask your conveyancer or solicitor what the contract requires, because these figures are not automatically equal.
Transfer duty, conveyancing and legal costs
- Transfer duty (stamp duty): depends on eligibility, dutiable value, thresholds and rates, as Revenue NSW's transfer duty guidance shows for NSW.
- Conveyancing and legal fees: vary by provider, state and contract complexity.
- Searches and certificates: needed to check title and property details.
No national stamp duty figure can be applied safely. Check the relevant state or territory revenue office, and do not assume first-home-buyer concessions apply to an investment purchase.
Inspections, valuation and lender costs
- Building and pest inspections
- Valuation fees
- Loan application, lender or broker fees
- LMI, where it applies
- Landlord and building insurance
Some borrowing costs may carry tax implications depending on purpose, ownership and current ATO rules. Speak with a registered tax adviser rather than assuming an outcome.
Cash reserves and holding-cost risk
Rent may not cover loan repayments and ownership costs, a risk Moneysmart flags for people borrowing to invest. Keep an accessible reserve for vacancy, repairs and rate changes. No single figure suits everyone, so size it to your cash flow and risk tolerance.
Why can borrowing capacity matter more than your deposit?
Borrowing capacity determines whether the loan can be serviced, while the deposit determines how much needs to be borrowed. You can hold plenty of cash and still fail a serviceability assessment. Equally, strong income does not help if you cannot fund duty and costs.
The affordable purchase price may also be lower than the maximum a calculator shows, because you need cash-flow resilience after settlement. Borrowing capacity for investment property is therefore a separate constraint, not a footnote to the deposit.
Income, existing debts and living expenses
Lenders typically look at several things together:
- your income and employment
- existing mortgages and other debts
- living expenses and dependants
- credit card limits, including unused ones
- credit history
Rental income, property expenses and serviceability assessment
Lenders may treat expected rent differently, so no universal treatment should be assumed. They may also assess property expenses, vacancy allowances and your existing debts. Ask your lender or broker how rent is counted in your case.
The role of the serviceability buffer
In May 2026, APRA kept the serviceability buffer at 3 percentage points. It is a regulatory setting for relevant lenders, not necessarily the interest rate you will pay. Individual lenders do not all assess applications identically.
How much deposit is needed at different purchase prices?
The table below is deposit-only arithmetic for planning. The investment property deposit figures are not lender quotes, buying-cost estimates or financial advice.
| Illustrative purchase price | 20% deposit | 80% LVR loan | 10% deposit scenario | 90% LVR loan |
|---|---|---|---|---|
| $500,000 | $100,000 | $400,000 | $50,000 | $450,000 |
| $600,000 | $120,000 | $480,000 | $60,000 | $540,000 |
| $800,000 | $160,000 | $640,000 | $80,000 | $720,000 |
The 10% column is not a universal lender offer. It may involve LMI, different pricing or extra assessment.
None of these figures include transfer duty, conveyancing, inspections, lender fees, valuation costs, LMI or a cash reserve. So total funds required will be higher than the deposit shown. A lender valuation below the purchase price could push the cash requirement higher again.
How should you prepare for an investment property deposit?
Treat deposit preparation as a total-funds plan with three checkpoints: finance, purchase costs and a downside reserve. Only then start searching for property.
Set a total-funds target, not only a deposit target
Start with a purchase range based on confirmed borrowing capacity. Add the deposit, your state's buying costs and a cash reserve. That sum, not the deposit alone, is your real savings goal.
Review savings, equity, liabilities and cash reserves
- Check existing debts and unused credit limits with a lender or broker.
- If using equity, arrange a current valuation.
- Consider paying down liabilities that reduce serviceability.
- Limit the loan to what you can carry, and keep accessible cash, in line with Moneysmart's borrowing guidance.
- Confirm ownership and tax implications with the right professionals.

When can Buyers Agency Australia help?
A buyers agent helps align a property decision with an investor's strategy and acquisition process. This section describes Buyers Agency Australia's stated approach. It is not an independent ranking or personal financial recommendation.
Founded by Dragan Dimovski, a property expert with 20+ years of personal property investment experience, Buyers Agency Australia describes a process covering goals, research, property selection, negotiation and settlement. Its framing suits deposit planning because a deposit should pass three gates: finance approval, property suitability and downside resilience.
Aligning the purchase with a property investment strategy
Before chasing a listing, it helps to clarify what role a property should play in your wider plan. That includes your goals, cash-flow limits and how this purchase fits alongside existing assets.
A strategy-first approach keeps the budget tied to your plan rather than to the largest loan a calculator allows. If you want to test your numbers against a plan, book a free strategy session.
Assessing property fit beyond the deposit
A buyers agent can support:
- location and property research
- due diligence on the shortlisted asset
- negotiation
- coordination through to settlement
A buyers agent does not replace your lender, mortgage broker, accountant, solicitor or conveyancer.
When this is not the right fit
This service may not suit you if you only want a loan quote, tax advice, legal advice or a guaranteed investment outcome. No buyers agent can promise approval, growth, rental income or a specific return.
Frequently asked questions about investment property deposits
How much deposit do I need for an investment property in Australia? Plan around 20% of the purchase price plus buying costs as a benchmark. Lender policy, your circumstances and the property can change the actual amount required.
Is a 20% deposit required for an investment property? No, not universally. Twenty percent is a common benchmark because it matches an 80% LVR, while a lower deposit may involve LMI and stricter assessment.
Can I buy an investment property with a 10% deposit? Possibly, under some lender policies. Approval, LMI, valuation and serviceability must be confirmed with the lender or a broker before you rely on it.
Can I use equity from my home as the deposit? Potentially, yes. Usable equity differs from total equity, needs lender valuation and confirmation, and does not guarantee approval.
What costs do I need to budget for besides the deposit? Budget for transfer duty, conveyancing, legal and search costs, inspections, valuation and lender costs, insurance and an accessible cash reserve.
Does LMI protect the borrower? No. LMI generally protects the lender if a borrower cannot repay, even though the borrower may bear the cost.
How does borrowing capacity affect an investment property deposit? The deposit is one part of the application. Income, debts, expenses, rent and serviceability settings also affect how much a lender will let you borrow.
Can rental income help me qualify for an investment property loan? Possibly, but treatment varies. Lenders may assess expected rent differently and also weigh expenses, vacancies and existing debts, so check with your lender or broker.
Should I use all my savings as the deposit? No universal rule applies. Using all available cash can leave too little for costs, vacancy, repairs and rate changes, so keep an accessible reserve.
Does a larger deposit mean the property is a better investment? No. A larger deposit affects financing, but property quality, location, cash flow, risk and portfolio strategy still determine suitability.
Next steps: turn your deposit into a purchase plan
Before you chase listings, work through three steps:
- Confirm the total funds available, including cash and verified usable equity.
- Confirm borrowing capacity, likely LVR, LMI exposure and state-specific purchase costs.
- Assess whether the property supports your strategy, cash flow and downside limits.
The decision rule is simple: do not set a property budget from your investment property deposit alone. If you would like help to map out your next property move, the team at Buyers Agency Australia can walk you through a strategy-led plan.
