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

Key Takeaways

• The standard benchmark is a 20 per cent deposit, which puts your loan-to-value ratio at 80 per cent and lets you avoid Lenders Mortgage Insurance.
• Budget an extra 5 to 7 per cent on top of the deposit for stamp duty, legal fees, and inspections.
• Some lenders accept a 10 per cent deposit, but you pay LMI, face higher repayments, and carry more risk.
• Your credit score, income, and serviceability matter as much as the deposit itself when a lender decides what to lend.
• If you already own property, usable equity can fund your next deposit without saving fresh cash.

Entering the Australian property market as an investor takes clear planning and a solid grasp of upfront costs, and the deposit is the largest initial hurdle you will face. Working out exactly how much capital you need can feel confusing given varying lender policies and shifting market conditions. Some buyers believe they need a huge amount of cash to start a portfolio, while others assume a tiny deposit will secure a premium house. The reality usually sits in the middle and depends on your financial situation.

As a Queensland buyers agency, Amassed helps investors navigate these financial requirements and secure premium assets without overpaying, guiding clients through the whole acquisition process so they can buy with confidence. This guide explains the standard deposit rules, alternative financing options, how your credit score shapes your loan, and practical strategies to fund your next purchase. It is general information only, not financial or credit advice, so confirm your position with a licensed mortgage broker or financial adviser before you commit.

How much deposit do you need for an investment property?

The most common benchmark for an investment property deposit in Australia is 20 per cent of the purchase price. In short, the deposit for investment property purchases usually starts at that 20 per cent mark. Lenders use the loan-to-value ratio, or LVR, to assess loan risk, which represents how much you borrow compared with the value of the property. With a 20 per cent deposit your LVR is 80 per cent, and most Australian banks treat an 80 per cent LVR as the standard benchmark for a safe loan.

For a practical example using typical Brisbane and South East Queensland price points, a property valued at $600,000 needs a $120,000 deposit, with the bank lending the remaining $480,000. A property valued at $800,000 needs a $160,000 deposit to reach the 20 per cent threshold. That benchmark gives you a clear savings target, but you must also account for additional upfront costs beyond the deposit, including state government stamp duty, legal and conveyancing fees, building and pest inspections, and loan establishment fees. A smart approach is to save the 20 per cent deposit plus an extra five to seven per cent to comfortably cover these purchasing costs.

Why does the 20 per cent rule exist?

Lenders prefer a 20 per cent deposit because it gives them a financial safety buffer. If property values fall or you default, the bank knows it can sell the property and recover its funds. When your deposit falls below 20 per cent, banks view the loan as higher risk and require you to pay Lenders Mortgage Insurance.

LMI is a one-off insurance premium, and it is crucial to understand that lenders mortgage insurance protects the lender, not you. If you cannot make repayments and the property sells for less than the outstanding balance, the insurance covers the bank for the shortfall. The cost varies with your loan size and LVR and can quickly reach tens of thousands of dollars. Buying a $700,000 property with a 10 per cent deposit might incur an LMI fee of $12,000 to $15,000. You can pay it upfront or capitalise it by adding it to the loan, though capitalising means paying interest on that premium for the life of the loan. Reaching a 20 per cent deposit generally lets you avoid LMI, which improves your long-term return and supports stronger positive cash flow by lowering your repayments.

Can you buy an investment property with a 10 per cent deposit?

You do not strictly need 20 per cent to buy an investment property. Some lenders offer investment loans to borrowers with a 10 per cent deposit, and in specific circumstances high-income earners might secure a loan with as little as five per cent. A smaller deposit lets you enter the market sooner, so buying today with 10 per cent means you start benefiting from capital growth immediately rather than waiting years to save more while prices potentially rise beyond your budget.

Low-deposit loans do carry real drawbacks. You will almost certainly pay LMI, which increases your overall debt. Borrowing 90 per cent of a property’s value means substantially higher monthly repayments, placing more pressure on your rental income and personal cash flow, so a few weeks of vacancy must be covered from your own pocket. A high LVR also leaves you exposed to interest rate rises and market dips, and if values decline shortly after you buy, you could fall into negative equity, owing the bank more than the property is worth. Securing a high-LVR loan is also getting harder, since the Australian Prudential Regulation Authority tightened limits on high debt-to-income lending in 2025, making banks more cautious about small-deposit investors carrying existing debt.

How does your financial profile affect how much you can borrow?

Banks do not just look at your deposit. They assess your entire financial profile, including income, expenses, credit history, and employment stability, to decide how much to lend. Lenders calculate your serviceability, checking whether you can comfortably afford repayments alongside living expenses, and they stress-test your application using an interest rate usually two to three per cent above the current market rate. Disciplined feasibility and serviceability analysis before you shop protects you from stretching too far.

Employment type matters too. Borrowers with stable, full-time Pay As You Go income are viewed favourably and may access a 10 per cent deposit option, while self-employed, freelance, or contract workers often face stricter scrutiny because variable income reads as riskier, sometimes prompting a bank to ask for a 20 or even 30 per cent deposit. Your credit score is equally vital, since a clean history signals you manage debt responsibly, while late payments or defaults can see an application declined or approved only with a much larger cash deposit.

How does your credit score affect your investment loan?

Before a bank looks closely at your income or deposit, it looks at your credit score. This single number acts as your financial passport, and a strong credit score for a home loan shapes your approval odds, your interest rate, and your borrowing capacity. In Australia there are three major credit reporting bodies, Equifax, Experian, and illion, and each uses its own algorithm, so your rating varies by agency. Equifax scores run from zero to 1,200, while Experian and illion run from zero to 1,000, and the higher your band, the more lenders compete for your business with their sharpest rates.

Your score is not a simple pass or fail. It directly influences several parts of your loan. First, approval, since lenders have minimum score thresholds and traditional banks decline applications that fall below them. Second, your interest rate, because many lenders use risk-based pricing, and over a 30-year loan even a small rate difference saves or costs tens of thousands. Third, your borrowing capacity and loan features, as a strong profile unlocks larger loans and options like offset accounts. Finally, if your deposit is under 20 per cent, the LMI insurer runs its own credit check and can decline to cover a loan even when the bank would approve it, which makes your score doubly important for low-deposit investors.

How can you improve your credit score before applying?

Credit scores are dynamic, so a disciplined approach can lift your rating before you apply. Start by obtaining a free copy of your report from Equifax, Experian, or illion and checking it for errors such as incorrect details, duplicate debts, or defaults you actually paid on time, then dispute anything wrong with the provider or bureau. Because payment history carries the most weight, paying every bill on time through direct debits or reminders is the single most effective habit, and consistent positive behaviour under Comprehensive Credit Reporting gradually lifts your score.

Beyond payments, manage your available credit. Lenders assess your total credit limits, not just balances, so cancelling unused cards or reducing limits instantly improves your borrowing power and lowers your utilisation. In the six to twelve months before a mortgage application, avoid new credit cards, personal loans, or store finance, since each hard inquiry signals possible financial stress and multiple applications in a short window drag your score down. If you are juggling several debts, consolidating high-interest cards and loans into one manageable facility simplifies repayments and reduces the risk of a costly missed payment.

What strategies can you use to build your deposit?

Gathering deposit funds takes discipline and a clear plan, and Australian investors typically use one of four routes.

Using equity from an existing home

If you already own property, you may not need to save cash at all. Equity is the difference between your property’s current value and your remaining mortgage, though banks generally let you access only up to 80 per cent of the value minus your loan, known as usable equity. If your home is worth $900,000, 80 per cent is $720,000, and subtracting a $400,000 mortgage leaves $320,000 of usable equity, enough to cover a 20 per cent deposit and costs on a new purchase. Our guide to using home equity walks through this in detail, and it is the fastest way to build a property portfolio without hundreds of thousands sitting in a savings account.

Budgeting, side income, and guarantor loans

For first-time investors without equity, saving cash is the main path, and it starts with a rigorous budget. Audit your monthly expenses, cut unused subscriptions, negotiate better rates on phone, internet, and energy, and redirect the savings into a dedicated high-interest account kept separate from everyday spending. Increasing your income accelerates the timeline, so many investors take on freelance work, sell goods online, or drive rideshare and channel every extra dollar into the deposit fund. A guarantor loan is another option, where a family member offers the equity in their own home as additional security, allowing you to borrow up to 100 per cent without LMI. It demands careful thought, because if you cannot repay, the bank can pursue the guarantor, though you can refinance to release them once the loan shrinks and the property grows in value.

Do deposit requirements change by property type and location?

The 20 per cent rule is a general guideline, and lenders adjust it for the property type and location because different assets carry different risk. Standard detached houses in metropolitan Brisbane or strong regional Queensland centres are highly desirable, so they attract standard criteria and an 80 per cent LVR is readily accepted. High-density units and apartments often trigger stricter rules, and many banks keep lists of restricted postcodes where a glut of new apartments threatens capital growth, capping the LVR at 70 per cent and forcing a 30 per cent deposit.

Off-the-plan properties add valuation risk, since you agree a price before construction and the bank values the finished property two years later, lending only against the lower figure if the market has softened and leaving you to cover the shortfall in cash. Regional Queensland offers a different dynamic, because the percentage stays the same but the cash amount is lower on more affordable stock, so a 20 per cent deposit on a $450,000 regional house is $90,000, a lower barrier to entry. Amassed monitors these location-based lending nuances, drawing on data from sources like CoreLogic and the Australian Bureau of Statistics, so clients target the right QLD markets for their borrowing capacity.

What are the final steps to securing your investment property?

Confirm your borrowing power first

Determining how much deposit you need is the foundation of a successful purchase. Assess your financial profile honestly, calculate your usable equity, review your household budget, and speak with a mortgage broker to confirm exactly how much a bank will lend you. A short strategy consultation helps you match a realistic budget to the right areas, and if you are buying in the capital, our Brisbane team can pinpoint suburbs that suit your borrowing capacity.

Then execute with expert help

Once your financing is clear, execution becomes the priority. Careful financial planning combined with expert acquisition advice sets you up for long-term wealth. You can contact our team to line up your purchase, and our track record in the client results shows what disciplined buying achieves once your deposit is ready.

Frequently Asked Questions

How much deposit do I need to avoid LMI?

You need a 20 per cent deposit, which sets your LVR at 80 per cent, to generally avoid Lenders Mortgage Insurance. On a $600,000 property that is $120,000. Saving an extra five to seven per cent on top covers stamp duty, legal fees, and inspections so you are not caught short at settlement.

Can I use my superannuation for a deposit?

Standard retail and industry super funds do not let you withdraw money for a property deposit. The only way to invest super in residential property is through a Self-Managed Super Fund, which carries strict compliance rules, setup fees, and ongoing audit costs. Seek independent advice from your accountant and the ATO’s SMSF guidance before pursuing it.

What is the minimum credit score for a home loan in Australia?

There is no universal minimum. Major banks typically look for a rating in the good band or above, generally over 600 to 650 depending on the bureau, while some specialist lenders accept scores in the 500s at a higher interest rate and larger deposit. A mortgage broker can gauge your position without leaving multiple marks on your file.

Do I need a bigger deposit for my second investment property?

The percentage usually stays the same, so you still aim for 20 per cent to avoid LMI. The bigger challenge is serviceability, because you must show the bank your income comfortably covers your home loan, your first investment loan, and the new proposed debt together.

Does checking my own credit score lower it?

No. Requesting a copy of your own credit report is a soft inquiry, which is not visible to lenders and has zero impact on your rating. You can check your report for free each year, and doing so is a smart way to monitor your financial health and catch errors early.

What extra costs should I budget alongside the deposit?

Set aside funds for state government stamp duty, which is the largest secondary cost, plus a conveyancer or solicitor, building and pest inspection reports, loan application fees, and a small buffer for immediate maintenance after settlement. Our guide to buyers agent costs covers professional fees if you engage representation.
