If you bought a home in Sydney any time before 2023, there’s a decent chance you’re sitting on a chunk of equity you haven’t thought much about. And if you’ve had thoughts about buying an investment property, that equity might be the answer to the deposit question.
Let me walk you through how it actually works — not the brochure version, the real version.
What Is Usable Equity?
Your equity is simply what your home is worth minus what you owe on it. But lenders don’t let you access all of it. Most will lend up to 80% of your property’s value without charging Lenders Mortgage Insurance (LMI). So the number that actually matters is your usable equity.
Here’s the formula:
(Property value × 80%) − Outstanding loan balance = Usable equity
Let’s use a real Sydney example. Say you bought a house in Penrith or Campbelltown a few years ago, and it’s now worth $1.4 million — which is pretty close to the Sydney median for a house right now. You’ve got $600,000 still owing on the mortgage.
$1,400,000 × 80% = $1,120,000
$1,120,000 − $600,000 = $520,000 usable equity
That’s $520k you can potentially put to work — enough for a deposit on a second property, potentially in one of Sydney’s outer suburbs where entry prices are still under $800k.
How Do You Actually Access It?
There are three common ways lenders let you get at your equity:
1. Loan Top-Up
Your existing lender increases your current mortgage. Simple, but your current lender may not have the most competitive investment rates — and they won’t tell you that. This works well if your current deal is solid and you want to keep things straightforward.
2. Refinance and Cash Out
You refinance your home loan with a new lender, borrowing more than you currently owe and taking the difference as cash (or having it apply to the new purchase). This gives you the chance to improve your home loan rate at the same time. Worth looking at if your current rate is above 6%.
3. Line of Credit
A revolving credit facility secured against your home. You draw on it as needed and only pay interest on what you use. Flexible, but requires discipline — some investors end up drawing on it for lifestyle spending, which defeats the purpose. Most lenders have also tightened serviceability requirements on these in recent years.
What Do Lenders Actually Look For?
Accessing equity sounds simple on paper. In practice, lenders are looking at a few things before they’ll say yes:
- Your total debt position — they’ll assess what your repayments look like across both properties
- Serviceability — can your income support both loans? They’ll add a 3% buffer on top of the actual rate when calculating this
- Rental income — most lenders will only count 70–80% of the expected rent from your investment property, not the full amount
- Loan-to-Value Ratio (LVR) — they’ll want the new purchase to stay within their LVR limits too
One thing that catches people out: just because you have $500k in equity doesn’t mean you can access all of it. Serviceability is a separate hurdle. A household earning $180,000 combined will have a very different borrowing capacity to one earning $100,000, regardless of the equity sitting in the home.
Where Are Sydney Investors Looking Right Now?
With Sydney’s median house price above $1.4 million, most equity investors are looking at units in the inner ring (Marrickville, Newtown, Leichhardt), houses in the outer west (Blacktown, Mount Druitt, Penrith corridor), or properties in Newcastle and Wollongong where yields are stronger. Some are also looking at dual-occupancy opportunities on larger western Sydney blocks — worth exploring if you’ve got the equity and the appetite.
The Trap to Avoid
Cross-collateralisation. Some lenders — particularly the big four — will link your home and investment property together as security under a single loan structure. It sounds harmless but it gives the bank enormous control. If you want to sell one property, you need their permission. If the investment drops in value, they may require you to inject more equity into the home loan too. A good broker structures these as separate loans with separate securities.
Should You Do It?
Equity access isn’t right for everyone. If you’re within 2–3 years of retirement, carrying high personal debt, or your income situation is uncertain, loading up on investment property debt might not stack up. But for a lot of Sydney homeowners in their 30s and 40s who bought before 2022, this is genuinely worth looking at.
The first step is knowing exactly what your equity position is and what borrowing capacity looks like across both properties. That’s a conversation I have with clients all the time — it takes about 30 minutes and you walk away knowing whether it’s viable or not.
