How to Use Equity to Invest in Property and                    Structure Your Loans Correctly

For many Australian property investors, building a property portfolio does not always require saving another full cash deposit. One of the most common strategies used by experienced investors is leveraging equity from an existing property to help purchase additional investments.

​

However, while accessing equity can help accelerate wealth creation, choosing the right loan structure is equally important. A poorly structured loan can create tax complications, reduce flexibility, and make future investing more difficult.

Understanding how equity works, how to structure investment loans correctly, and the difference between positive and negative gearing can help investors make smarter long-term decisions.

​

What Is Equity?

Equity is the difference between your property’s value and the amount you still owe on the mortgage.

​

Example

• Property value: $1,200,000

• Existing home loan: $700,000

Available equity:

1,200,000−700,000=500,000

​

In this example, the homeowner has $500,000 equity in the property.

However, lenders usually will not allow borrowers to access all of that equity.

Most Australian lenders generally allow borrowing up to 80% of the property value without paying Lenders Mortgage Insurance (LMI). 

​

Accessible equity calculation:

Example

• Property value: $1,200,000

• 80% lending limit:

1,200,000×80%=960,000

​

Less existing loan:

• $960,000 − $700,000

Accessible equity:

960,000−700,000=260,000

This means the borrower may potentially access around $260,000 equity for investment purposes, subject to lender approval and servicing.

How Do Investors Use Equity?

Property investors commonly use equity to fund:

• Deposits for investment properties

• Stamp duty and purchasing costs

• Renovations

• Share investments

• Debt recycling strategies

Instead of saving another cash deposit, equity can effectively act as the deposit for the next purchase.

Example – Using Equity to Buy an Investment Property

Assume:

• Owner-occupied property worth $1.5 million

• Existing loan balance: $800,000

• Investor wants to buy a $700,000 investment property

Step 1 – Access Equity

Maximum 80% lending against home:

1,500,000×80%=1,200,000

​

Available equity:

1,200,000−800,000=400,000

​

The investor may access part of this equity to cover:

• 20% deposit

• Stamp duty

• Legal fees

Step 2 – Separate Investment Loan

The lender may create:

• Existing home loan split

• Equity release split

• New investment property loan

This structure is extremely important for tax and future flexibility.

Why Loan Structure Matters

Many investors focus only on buying property but overlook loan structuring, which can significantly impact:

• Tax deductibility

• Cash flow

• Future borrowing capacity

• Flexibility

• Asset protection

Poor loan structuring can create “mixed-purpose loans,” making tax deductions complicated and difficult to track. (ato.gov.au)

Best Loan Structure for Property Investors

While every situation is different, many experienced investors prefer the following strategies.

1. Separate Loan Splits

Instead of combining all debt together, separate loan splits can help:

• Keep tax records cleaner

• Identify deductible debt

• Improve future refinancing flexibility

Example Structure

Owner Occupied Home

• Split 1: Home loan

• Split 2: Equity release for investment deposit

Investment Property

• Separate investment loan

This avoids mixing personal and investment debt.

2. Interest-Only Investment Loans

Some investors choose interest-only repayments on investment loans to:

• Improve short-term cash flow

• Maximise tax deductibility

• Preserve cash for future investments

Meanwhile, they may focus on paying down non-deductible owner-occupied debt faster.

However, interest-only loans are not suitable for everyone and can increase long-term interest costs. (moneysmart.gov.au)

3. Offset Accounts

Many investors use offset accounts strategically because:

• They reduce non-deductible interest

• Maintain flexibility

• Preserve future tax effectiveness

For example, investors often prefer placing surplus savings into an offset account attached to their owner-occupied loan rather than directly paying down the loan principal.

This can become important if the property later converts into an investment property.

4. Avoid Cross-Collateralisation

Cross-collateralisation happens when multiple properties are tied together under one lending structure.

Many experienced investors try to avoid this because it may:

• Reduce flexibility

• Complicate refinancing

• Give lenders greater control over multiple properties

Instead, stand-alone lending structures are often preferred where possible.

Understanding Negative Gearing

Negative gearing occurs when the costs of owning an investment property exceed the rental income received.

Example

Annual rental income:

• $32,000

Annual expenses:

• Interest

• Rates

• Insurance

• Maintenance

• Depreciation

Total expenses:

• $40,000

Annual loss:

32,000−40,000=−8,000

This $8,000 loss may potentially reduce taxable income, depending on personal circumstances and tax advice. (ato.gov.au)

Many Australian investors accept short-term losses expecting:

• Long-term capital growth

• Future rental increases

• Tax benefits

However, negative gearing should not be the only reason for buying a property.

Understanding Positive Gearing

​

Positive gearing occurs when rental income exceeds property expenses.

Example

Rental income:

• $45,000

Expenses:

• $35,000

Annual profit:

45,000−35,000=10,000

This surplus income improves cash flow but may increase taxable income.

Positive gearing is often more common when:

• Interest rates are lower

• Rental yields are strong

• Properties are held long term

• Debt levels reduce over time

Which Is Better – Positive or Negative Gearing?

There is no universal answer.

Negative Gearing May Suit Investors Who:

• Have higher taxable income

• Prioritise capital growth

• Have strong cash flow

• Can manage short-term losses

Positive Gearing May Suit Investors Who:

• Want stronger cash flow

• Prefer lower financial stress

• Focus on passive income

• Are nearing retirement

The best strategy depends on:

• Financial goals

• Risk tolerance

• Income level

• Borrowing capacity

• Investment timeframe

Common Mistakes Investors Make are as below: 

​

Mixing Personal & Investment Debt

This can create major tax complications.

Using Equity Without a Strategy

Borrowing simply because equity exists can increase financial risk.

Over leveraging

High debt levels may become difficult to manage during:

• Interest rate rises

• Vacancy periods

• Economic downturns

Focusing Only on Tax Benefits

A poor investment does not become good simply because it is negatively geared.

Why Professional Advice Matters

Property investing involves:

• Lending structure

• Tax strategy

• Cash flow management

• Long-term planning

Working with:

• A mortgage broker

• Accountant

• Financial adviser

can help investors structure loans correctly and avoid costly mistakes.

Final Thoughts

Using equity can be a powerful way for Australian property investors to build wealth and expand their portfolio faster. However, the way loans are structured can significantly impact tax effectiveness, borrowing flexibility, and long-term financial outcomes.

Understanding separate loan splits, offset strategies, interest-only lending, and the difference between positive and negative gearing is essential before investing further.

The best investment loan structure is not always the one with the lowest interest rate — it is the structure that supports your long-term financial goals while maintaining flexibility and managing risk effectively.
