How to Use Your Home Equity to Buy an Investment Property

What Is Home Equity?

Equity is the difference between what your home is worth and what you still owe on it.

If your home is currently valued at $850,000 and your remaining mortgage balance is $450,000, your equity is $400,000.

Not all of that is accessible. Most lenders will allow you to borrow against your property up to 80% of its value without requiring Lenders Mortgage Insurance (LMI). That means the usable equity in this example looks like this:

80% of $850,000 = $680,000
Minus your existing mortgage balance of $450,000
Usable equity = $230,000

That $230,000 could become your deposit and purchasing costs for an investment property. It's not cash in hand yet, but with the right loan structure, it can be mobilised.

How Does Accessing Equity Work?

There are a few ways to unlock your equity for investment purposes. The right approach depends on your circumstances, your existing lender, and the investment strategy you're pursuing.

Refinancing to release equity

You refinance your current home loan with a new lender or restructure your existing loan. As part of this process, you increase your borrowing to the maximum the lender will allow against your property's value. The difference between your new loan amount and your existing balance is released as cash or a line of credit.

A home equity loan

Some lenders offer a separate loan secured against your existing property. Rather than touching your current mortgage structure, you access the equity as a standalone facility. This can suit people who have a competitive existing rate they don't want to disturb.

A line of credit

A revolving credit facility secured against your property that you can draw on as needed. This offers flexibility, though it requires discipline, and interest is charged on the amount drawn.

Each of these structures has implications for your interest rate, loan terms, and tax position. Getting the right structure from the start makes a meaningful difference over time.

What Can the Equity Be Used For?

When you access equity to purchase an investment property, the released funds typically cover:

The deposit on your investment property (usually 20% to avoid LMI on the investment loan)
Stamp duty and government feesLegal and conveyancing costs
Pest and building inspections
Any immediate renovation or repairs required

In some cases the equity covers the full deposit requirement, meaning you're able to purchase an investment property with no additional cash out of pocket. That said, this approach depends on the numbers stacking up, and on both properties being able to service their respective loans.

The South Coast Angle

Property along the Shoalhaven and Illawarra has seen strong growth over recent years, and many long-term owners have built up meaningful equity as a result. For people who bought in areas like Berry, Gerringong, Nowra, Mollymook or Kiama before the market moved, that equity is now substantial.

At the same time, the South Coast investor market remains active. Properties that appeal to the holiday rental market, the sea-change buyer and the remote-worker community create different opportunities than a metropolitan investment. Understanding what kind of investment suits your financial position, and what lenders look for in an investment loan secured against a coastal property, is something a local broker can help you navigate.

Things to Think About Before You Access Your Equity

Using your home equity to invest is a sound strategy for many people, but it does come with considerations worth working through:

Your borrowing capacity

Lenders will assess your ability to service both your existing mortgage and the new investment loan. This means your income, existing commitments and the rental income from the investment property all come into the calculation. Serviceability, not just equity, determines what you can borrow.

The impact on your existing loan

Increasing your borrowing reduces your buffer and may extend your loan term. If you're close to having your home paid off, accessing equity requires a considered conversation about the trade-offs.

Tax implications

Interest on an investment loan is generally tax deductible. But how you structure the loan matters. Mixing investment debt with owner-occupied debt can create complications when it comes to deductibility. A mortgage broker and your accountant working together can help you get this right from day one.

Property selection

Equity provides purchasing power. What you do with it still matters. A well-chosen investment property in a strong rental market with good long-term fundamentals will serve you far better than a rushed purchase.

How a Mortgage Broker Can Help

Accessing equity sounds straightforward, but the execution involves several moving parts.

A broker will assess your current loan, get an up-to-date valuation, and work out your actual usable equity with precision. Our team at Shorebreak Finance will then compare lenders across the market to find a structure that works for both your owner-occupied loan and the investment loan, whether that's with the same lender or two separate ones.

We can also help you understand how to set up the investment loan in a way that keeps things clean for tax purposes, and work alongside your accountant if you have one.

For South Coast clients, the added local knowledge of what lenders look for in properties in this region, what valuation risks exist in coastal markets, and which lenders are currently competitive for investment lending makes a real difference.

The First Step

If you've owned your home for a few years and you're curious about whether your equity could do more work for you, the starting point is a conversation.

We can look at your current loan, calculate your usable equity, and have an honest conversation about whether the numbers support an investment purchase, and what that could look like for your situation.

It starts with a coffee.
