How Much Deposit Do You Need for an Investment Property in Australia?

The deposit is the single biggest barrier to entry for most property investors in Australia. Unlike owner-occupier loans, investment property loans come with stricter lending criteria, higher interest rates, and larger minimum deposit requirements. Getting the deposit wrong can mean paying thousands of dollars in unnecessary insurance, or worse, having your loan application rejected entirely.

This guide explains exactly how much deposit you need for an investment property in 2026, what costs to budget for beyond the deposit itself, and how to structure your finances to give yourself the strongest possible position with lenders.

The Minimum Deposit: 10% vs 20%

Most Australian lenders require a minimum deposit of 10% of the property's purchase price for an investment loan. However, the practical minimum for most investors is 20%, and there is a significant financial reason for that distinction.

When you borrow more than 80% of a property's value (known as a loan-to-value ratio or LVR above 80%), lenders require you to pay Lenders Mortgage Insurance (LMI). LMI protects the lender, not you, in the event you default on the loan. It is a one-off premium that can cost anywhere from $8,000 to $40,000 or more depending on the loan size and LVR.

Here is how the deposit requirement breaks down for a $700,000 investment property:

| Deposit % | Deposit Amount | LVR | LMI Required | Approximate LMI Cost | |---|---|---|---|---| | 10% | $70,000 | 90% | Yes | $15,000 - $22,000 | | 15% | $105,000 | 85% | Yes | $6,000 - $10,000 | | 20% | $140,000 | 80% | No | $0 | | 25% | $175,000 | 75% | No | $0 |

The difference is stark. An investor putting down 10% on a $700,000 property might pay $18,000 or more in LMI on top of their $70,000 deposit. That LMI premium is typically capitalised onto the loan, meaning you pay interest on it for the entire loan term. Over 30 years, that $18,000 in LMI can cost you over $35,000 in total repayments.

For this reason, 20% is the target deposit for most serious investors. It eliminates LMI entirely, secures a lower interest rate, and demonstrates financial discipline to the lender.

Total Upfront Costs Beyond the Deposit

The deposit is only one part of the cash you need at settlement. Many first-time investors are caught off guard by the additional costs that must be paid upfront. For a $700,000 investment property, here is a realistic budget:

| Cost | Approximate Amount | |---|---| | Deposit (20%) | $140,000 | | Stamp duty (varies by state) | $15,000 - $37,000 | | Conveyancing/legal fees | $1,500 - $3,000 | | Building and pest inspection | $600 - $1,000 | | Loan application/establishment fees | $0 - $600 | | Landlord insurance (first year) | $1,200 - $1,800 | | Quantity surveyor (depreciation schedule) | $600 - $800 | | Council and water rate adjustments | $500 - $1,500 |

Total cash required: approximately $160,000 - $185,000

Stamp duty is the second-largest cost after the deposit itself, and it varies dramatically between states. A $700,000 property in Queensland attracts roughly $13,000 in stamp duty, while the same property in Victoria costs approximately $37,000. For a detailed breakdown by state, see our stamp duty calculator guide.

How Lenders Assess Investment Loan Applications

Investment loans are assessed differently from owner-occupier loans. Lenders apply stricter serviceability criteria because investment properties carry additional risks, including vacancy periods, maintenance costs, and the possibility of rental income falling short of projections.

Here are the key factors lenders evaluate:

1. Rental income shading. Lenders do not count 100% of the expected rental income when assessing your ability to service the loan. Most banks apply a "shading" of 70% to 80%, meaning they only consider 70 to 80 cents of every dollar in rental income. If your property is expected to earn $600 per week, the lender may only count $420 to $480 per week in their serviceability calculation.

2. Interest rate buffer. Since late 2021, APRA has required lenders to assess borrowers at an interest rate at least 3 percentage points above the loan's actual rate. If you are offered a rate of 6.2%, the lender tests whether you can afford repayments at 9.2%. This buffer significantly reduces borrowing capacity.

3. Existing debts and liabilities. Credit cards, car loans, HECS-HELP debt, personal loans, and existing mortgages all reduce your borrowing power. A $10,000 credit card limit, even if unused, can reduce your borrowing capacity by $30,000 to $50,000 because lenders assume you could draw the full limit at any time.

4. Genuine savings. Lenders want to see that your deposit comes from genuine savings accumulated over time, not from a one-off gift or cash advance. A consistent savings pattern over three to six months strengthens your application substantially.

Using Equity from an Existing Property

If you already own a property, whether it is your home or another investment, you may not need to save a cash deposit at all. Instead, you can use the equity in your existing property as security for the new investment loan.

Equity is the difference between your property's current market value and the amount you owe on it. Most lenders will allow you to access up to 80% of the property's value minus your outstanding loan balance.

Example:

• Your home is valued at $900,000
• You owe $400,000 on your mortgage
• Available equity: ($900,000 x 80%) - $400,000 = $320,000

That $320,000 could serve as the deposit and cover settlement costs on one or even two investment properties without you needing to contribute any additional cash. This is the most common strategy used by experienced investors to build a portfolio.

However, there are important caveats. Accessing equity increases the debt secured against your home. If investment property values decline or rental income drops, you still owe the full amount. You also need sufficient income to service the combined debt across all properties.

For those starting their investment journey, our beginner's guide to property investment covers the foundational principles before you commit to leveraging equity.

Can You Buy an Investment Property with $20,000 to $30,000?

This is one of the most common questions from aspiring investors, and the short answer is: technically yes, but practically it is very difficult in most Australian markets.

If you have a deposit of $23,000 and are borrowing at a 90% LVR (10% deposit), that covers a property priced up to roughly $230,000 before any other costs are factored in. The problem is that your $23,000 needs to cover more than just the deposit. Stamp duty, conveyancing fees, building inspections, and loan establishment costs can easily consume $8,000 to $15,000 of that amount, leaving far less than 10% for the actual deposit.

There are some regional areas where properties around the $200,000 mark still exist. Parts of regional Queensland, South Australia, and Tasmania have houses and units in this price range. However, these markets come with their own risks, including lower rental demand, limited capital growth, and higher vacancy rates.

At this price point, LMI is also a significant factor. Borrowing 90% on a $200,000 property means paying roughly $3,500 to $5,500 in LMI, which further reduces how much of your cash goes toward actual equity.

If you already own a property, a more practical approach is to use equity rather than relying solely on cash savings. Even a modest amount of equity in an existing home can cover the deposit and upfront costs on a lower-priced investment property without draining your savings.

One important reality check: even after settling the purchase, you need a cash buffer for holding costs. Vacancy periods, repairs, insurance, and council rates can arise in the first few months before rental income stabilises. Most financial advisers recommend keeping at least three to six months of holding costs in reserve, which could be another $5,000 to $10,000 depending on the property.

Total Cash Required for Investment Properties at Different Price Points

The table below shows the deposit required at 10%, 15%, and 20% for common property price points, along with approximate LMI costs and stamp duty. Stamp duty figures use NSW investor rates as an example. Your state may differ significantly, so check our stamp duty guide for a full breakdown.

| Price Point | 10% Deposit | LMI at 10% (approx.) | 15% Deposit | LMI at 15% (approx.) | 20% Deposit (no LMI) | Stamp Duty (NSW, approx.) | |---|---|---|---|---|---|---| | $400,000 | $40,000 | $8,000 - $12,000 | $60,000 | $3,000 - $5,000 | $80,000 | $13,500 | | $500,000 | $50,000 | $11,000 - $16,000 | $75,000 | $4,500 - $7,000 | $100,000 | $17,800 | | $600,000 | $60,000 | $13,000 - $19,000 | $90,000 | $5,500 - $8,500 | $120,000 | $22,500 | | $750,000 | $75,000 | $16,000 - $24,000 | $112,500 | $7,000 - $11,000 | $150,000 | $29,200 | | $1,000,000 | $100,000 | $22,000 - $33,000 | $150,000 | $9,000 - $15,000 | $200,000 | $40,500 |

As the table illustrates, the gap between a 10% and 20% deposit is not just the extra cash. At 10%, you are also paying tens of thousands in LMI that you would avoid entirely at 20%. For a $600,000 property, saving the extra $60,000 to reach 20% could save you $13,000 to $19,000 in LMI alone, not including the interest you would pay on that capitalised LMI over the life of the loan.

First-Time Investor vs Experienced Investor

Your deposit strategy should reflect where you are in your investment journey.

First-time investors typically need to save a cash deposit. The most effective approach is to set a clear target (usually 20% of your intended purchase price plus 5% for costs), open a dedicated high-interest savings account, and automate regular contributions. At current savings rates around 5%, a disciplined saver putting aside $2,000 per month can accumulate a $140,000 deposit in roughly five and a half years, including interest.

First-time investors should also investigate the First Home Super Saver Scheme (FHSSS), which allows you to withdraw voluntary super contributions (up to $50,000) to put towards a property purchase. While primarily designed for owner-occupiers, it can accelerate your deposit timeline if you plan to live in the property initially before converting it to an investment.

Experienced investors with existing property typically use equity rather than cash. The focus shifts from saving a deposit to maximising equity growth in existing properties (through renovations, principal repayments, or market appreciation) and maintaining strong serviceability across the portfolio.

Experienced investors also have more options when structuring loans. Cross-collateralisation (using multiple properties as security for a single loan) is one approach, though many advisers recommend keeping loans separate with individual securities to limit risk exposure.

Strategies to Reach Your Deposit Faster

If you are working towards your first investment property deposit, these strategies can accelerate the timeline:

Reduce discretionary spending ruthlessly. The difference between saving $1,500 and $2,500 per month is roughly two years off your deposit timeline on a $700,000 target property.

Salary sacrifice into super, then use the FHSSS. Contributions up to $50,000 can be withdrawn at a concessional tax rate of 15%, which is significantly lower than most marginal tax rates. This effectively gives you a tax-efficient savings vehicle.

Consider a smaller market first. If $700,000 is out of reach, starting with a $450,000 property in a regional growth area requires a 20% deposit of only $90,000. Building equity in a smaller property can fund the deposit for larger acquisitions later. Tools like PropBuyAI can help you compare rental yields across different price brackets and suburbs to find the best entry point.

Reduce existing debts. Paying off a car loan or closing unused credit cards improves your borrowing capacity and frees up cash for saving.

Look into guarantor loans. Some lenders allow a family member to guarantee part of your loan using equity in their own property. This can reduce or eliminate the deposit requirement, though it places the guarantor's property at risk if you default.

How Negative Gearing Affects Your Cash Flow After Purchase

Once you have secured the property, the deposit conversation shifts to ongoing holding costs. A negatively geared investment property means you are paying money out of pocket each month, which can strain cash flow if you have stretched too far on the deposit.

Understanding the interplay between your deposit size, loan repayments, rental income, and tax deductions is essential before committing. A larger deposit means lower loan repayments and potentially a positively geared property from day one. A smaller deposit means higher repayments and a greater reliance on negative gearing tax benefits to manage the shortfall.

Key Takeaways

• 20% is the benchmark deposit for investment property loans in Australia. Going below this triggers LMI, which can cost $10,000 to $25,000 or more.
• Budget for 25% of the purchase price in total cash to cover the deposit, stamp duty, and all settlement costs comfortably.
• Lenders assess investment loans more strictly than owner-occupier loans, shading rental income and applying a 3% interest rate buffer.
• Equity in an existing property is the most powerful tool for funding investment deposits without cash savings.
• First-time investors should target a clear savings goal, explore the FHSSS, and consider starting in a more affordable market to build equity.

The deposit is the hardest part of property investment. Once you clear that hurdle and secure a quality asset in a strong location, time and compounding growth do the heavy lifting.

Frequently Asked Questions

What is the minimum deposit for an investment property in Australia?

Most Australian lenders require a minimum deposit of 10% for an investment property loan. However, 20% is the recommended target because it avoids Lenders Mortgage Insurance (LMI), which can cost $8,000 to $40,000 depending on the loan size and LVR. Budget an additional 5% of the purchase price for stamp duty, legal fees, and other settlement costs.

How much does Lenders Mortgage Insurance (LMI) cost on an investment property?

LMI costs vary based on the loan amount and deposit size. For a $700,000 investment property with a 10% deposit, LMI typically costs $15,000 to $22,000. At a 15% deposit, it drops to $6,000 to $10,000. A 20% deposit eliminates LMI entirely, which is why most experienced investors target this threshold. For a full breakdown, see our LMI guide.

Can I use equity from my existing home to buy an investment property?

Yes. Most lenders allow you to access up to 80% of your existing property's value minus the outstanding loan balance. For example, a home valued at $900,000 with a $400,000 mortgage gives you $320,000 in accessible equity. This is the most common strategy used by experienced investors to fund deposits without additional cash savings.

How does the First Home Super Saver Scheme (FHSSS) help with a deposit?

The FHSSS allows you to withdraw up to $50,000 in voluntary super contributions at a concessional tax rate of 15%, which is lower than most marginal tax rates. While primarily designed for owner-occupiers, it can accelerate your deposit timeline if you plan to live in the property initially before converting it to an investment. Salary sacrificing into super and withdrawing via the FHSSS is one of the most tax-efficient ways to build a deposit faster.

How much deposit do I need for a $500,000, $700,000, or $1,000,000 investment property?

At 20% (no LMI), you need $100,000 for a $500,000 property, $140,000 for a $700,000 property, and $200,000 for a $1,000,000 property. Including stamp duty and settlement costs, budget approximately $125,000, $175,000, and $250,000 respectively in total upfront cash.
