How to Use Equity in Your Home to Buy Multiple Properties

Jack ChenDecember 202412 min read

If you own a home in Australia, there's a good chance you're sitting on equity that could be used to purchase investment properties — without waiting years to save another deposit.

The investors who build serious portfolios aren't necessarily the ones with the highest incomes. They're the ones who understand how to use equity properly.

What Is Equity?

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

Current property value$800,000
Mortgage owing$400,000
Your equity$400,000

What Is Usable Equity?

Usable equity is the portion you can actually access. Most banks will only lend up to 80% of your property's value.

Property value$800,000
80% of value$640,000
Less mortgage owing$400,000
Usable equity$240,000

Important: This $240,000 isn't cash in your account. You need to apply for it like any other loan — the bank will assess your income, expenses, and credit history.

How Equity Funds Your Next Property

To buy an $800,000 investment property, you typically need:

CostAmount
20% deposit (to avoid LMI)$160,000
Stamp duty & fees~$40,000
Total required~$200,000

With $240,000 in usable equity, you could fund this purchase and still have $40,000 accessible for future use.

Saving vs Using Equity: The Timeline

ApproachMonthly SavingsTime to $200K
Saving $2,000/month$2,000~8 years
Saving $3,000/month$3,000~6 years
Using equityNow

The challenge with waiting: property prices are growing at over 6% annually. An $800,000 property today could be worth ~$1,100,000 in six years.

The Compounding Effect

When you own two properties instead of one, both are growing in value simultaneously.

Using the example above — if you purchase your second property now using equity, by year 3 you could have enough usable equity again to purchase a third property. This compounds over time, potentially allowing you to hold four to five properties within 7–8 years.

How to Access Your Equity

You have two options:

1. Stay with your current lender

Simpler process, but may not get the best outcome.

2. Shop around

Different banks use different valuation methods. One bank might value a property at $800,000 while another values it at $850,000. That extra $50,000 in valuation means an extra $40,000 in accessible equity.

How to Structure Your Loans

This is critical for both flexibility and tax purposes.

Don't do this:

Simply top up your existing home loan. Your home loan is non-deductible, but borrowing for an investment property is tax-deductible. If you mix them together, you create a mess at tax time.

Do this instead:

Ask for a loan split.

LoanAmountPurposeTax Deductible?
Loan 1$400,000Original home loanNo
Loan 2$200,000Equity for investmentYes

Both loans are secured against your home, but tracked separately with their own statements. Your accountant can clearly see which interest is claimable.

Avoid Cross-Collateralisation

This is when the bank bundles all your properties together as security for all your loans. It's convenient for them, not for you.

The problem:

If you want to sell one property, the bank may block it until they're satisfied the remaining property covers all remaining debt. This limits your control.

Always insist on separate loans for separate properties.

Cash Flow Reality Check

Before using equity to invest, understand the real costs.

Monthly CostsAmount
Loan repayments ($640K at 6%)~$4,900
Rates, insurance, property management~$500
Total costs~$5,400
Rental income~$3,000
Out of pocket (before tax)~$2,400

Now factor in tax benefits:

Tax BenefitAmount
Interest (~$48K/year) at 37% bracket~$1,500/month
Real cost after tax~$900–$1,000/month

That's roughly $230/week out of pocket.

Questions to ask yourself:

  • Can I comfortably afford $1,000/month?
  • What if the property is vacant for a month?
  • What if interest rates rise another 1%?

If you can handle this with a buffer for unexpected costs, it's manageable. If not, it may be worth waiting.

Who This Strategy Suits

This is a 10–15 year wealth-building approach. It works best if you have:

  • Stable, predictable income
  • Financial discipline
  • Patience to ride out market cycles
  • Comfort with holding debt long-term

If you're already stretched on your current mortgage or uncertain about future income, this strategy may not be right for you yet.

Next Steps

Every property owner's situation is different — your income, existing debt, property values, and goals all factor into the right approach.
