How to use equity to buy investment property

For many homeowners, equity can be a practical way to step into property investment without saving a full cash deposit from scratch. If you already own a home and it has increased in value over time, you may be able to use equity to buy an investment property and start building a stronger long-term financial position.

In simple terms, equity is the difference between your property’s current market value and what you still owe on your mortgage. As your loan balance falls and the value of your home rises, you build equity that may be available to access, subject to lender approval and your borrowing capacity.

For many Australians, buying an investment property with equity can be an effective way to grow a property portfolio, but it is not the right move for everyone. 

Before using home equity to buy investment property, it is important to understand how equity works, how much equity may be available, and what risks are involved.

What does it mean to use equity to buy investment property?

When people talk about using equity to buy investment property, they usually mean borrowing against the equity in their existing home to help fund the deposit, stamp duty, and other upfront costs for a new property.

This doesn’t mean the bank gives you free money. It means you’re increasing your total loan amount by using the value built up in your existing property as security. That’s why it’s important to look at your financial circumstances, current loan, living expenses, and broader investment strategy before moving ahead.

Many investors choose this path because it can help them buy an investment property sooner. Rather than waiting years to save another deposit, they may be able to use available equity in their existing home to access the funds they need for a second property or even multiple properties over time.

How much equity can you use?

A common question is how much equity you actually need. The answer depends on your property value, existing loan, income, credit history, and lender policy.

In most cases, lenders will allow you to access up to 80% of the current market value of your home without needing to pay LMI. This is often referred to as usable equity. It’s the portion of equity that may be borrowed against while keeping the loan-to-value ratio at or below 80%.

Here is a simple example:

• Current market value of your existing home: $800,000
• 80% of the property value: $640,000
• Current mortgage balance: $500,000
• Usable equity: $140,000

In this example, the available equity is $140,000. That amount could potentially be used toward buying an investment property, subject to serviceability and loan approval.

The exact loan amount a lender will offer depends on more than just value. They’ll also look at your income, financial commitments, offset account balances, existing debts, and whether your personal situation can comfortably support another loan.

Why many investors use home equity to buy an investment property

Using equity can be appealing because it may help you move faster and make better use of an asset you already own. If your existing property has seen solid capital growth, that growth may create an opportunity to buy property again without starting from zero.

Some of the common benefits include:

• You may not need to save a full cash deposit
• Property-backed lending usually has lower interest rates than unsecured debt
• You can keep cash in reserve as a safety net
• You may be able to grow rental income and long-term capital growth sooner
• It can support a broader property investment or wealth-building plan

For homeowners who want to build equity and expand into a second home or investment property, this can be a useful strategy. It may also help if your goal is to generate additional income through rental income while building a property portfolio over time.

What are the risks of using equity?

While there can be a true benefit to using equity, it also increases risk. You’re taking on more debt, which can put pressure on your cash flow if your circumstances change.

Some of the main risks involved include:

• Higher overall debt levels
• Increased risk if interest rates rise
• Greater exposure to changes in property value
• Less flexibility if rental income drops or the property is vacant
• Higher repayments that may create financial stress

It’s also worth remembering that your home may be used as security for the new lending structure. If you cannot meet repayments, the consequences can be serious. That’s why professional advice matters; before using equity to buy, you should have a clear view of your income, living expenses, financial commitments, and how much buffer you want to keep in place.

Using investment property equity to purchase property: what lenders look at

Using investment property equity to purchase property is possible, but lenders do not assess equity in isolation. They look at the full picture. Along with your available equity, they may review:

• Your income and employment stability
• Your repayment history
• Your credit history
• Your existing home loan and any other debts
• The current market and recent sales history in your area
• The value of your home and the value of the new property
• Your financial circumstances and personal situation

This is why two borrowers with the same amount of equity may get very different outcomes. One may qualify for a strong loan amount, while another may not meet serviceability requirements due to other factors.

 Tax considerations and why advice matters

Tax deductions may be available when money is borrowed for investment purposes, but the tax implications depend on how the funds are used and how the loan is structured. 

This is not something to guess. Before making a move, speak with an accountant or financial planner, a financial adviser, or a registered tax agent who can provide tax advice based on your circumstances. Good lending advice and good tax advice should work together.

For example, some borrowers set up separate loan splits to make it clear which funds were used to purchase an investment property. That can matter for record keeping and may affect how interest is treated for tax purposes. The structure needs to fit your investment strategy, not just get the deal approved.

Is a home equity loan the best option?

A home equity loan can be one way to access funds, but it is not the only structure available. Depending on your lender and goals, you may be able to refinance, top up your existing home loan, or set up a separate loan split.

The best option depends on what you want to achieve. You may want to keep your owner-occupier debt separate from investment debt. You may want to avoid cross-collateralising properties. Or you may want flexibility for future purchases if your plan involves investing across multiple properties.

This is where working with home loan specialists like Watson Mortgages can help. The right lending structure can make it easier to manage repayments, track interest, and stay aligned with your broader financial goals.

Debt recycling can be another way to use equity strategically

For some borrowers, debt recycling may form part of a broader investment strategy. This approach generally involves restructuring non-deductible home loan debt into investment debt over time, often while directing surplus income toward reducing owner-occupier debt faster.

Debt recycling can be effective in the right circumstances, but it’s more complex than simply buying an investment property with equity. It may have tax implications, cash flow considerations, and lending structuring issues that need careful planning. Anyone considering this strategy should seek professional advice from a financial adviser, accountant or registered tax agent before making changes to their loan structure.

How to use equity to buy an investment property without overextending yourself

If you’re thinking about using home equity to buy an investment property, start by looking at the numbers honestly. Don’t focus only on how much equity you have; focus on how comfortably you can manage the debt.

Ask yourself:

• Can I afford higher repayments if interest rates rise?
• Do I have a safety net for vacancies, repairs, or unexpected costs?
• Will this purchase support my long-term investment strategy?
• Am I comfortable with the potential risks and the upsides?
• Have I factored in all costs, not just the deposit?

Buying an investment property with equity can be a smart move when it’s backed by strong planning, but borrowing more money always comes with responsibility. The goal is not simply to access equity. The goal is to use equity well.

“Strategy is about making choices; it’s about deliberately choosing to be different.” — Michael Porter
