You bought your first property years ago. It has gone up in value, the loan balance has come down, and somewhere in the back of your mind you have wondered whether that equity is doing anything useful. This post explains the mechanics of accessing equity, what lenders actually allow, how the process repeats, and where an SMSF fits in.
What "Usable Equity" Actually Means
Total equity is simply your property's current market value minus your outstanding loan balance. But total equity is not the same as what a lender will let you borrow against. Most Australian lenders cap usable equity at about 80% of the property value to avoid Lenders Mortgage Insurance (LMI) and reduce default risk.
The working formula is straightforward:
- Usable equity = (current value x 0.80) minus outstanding loan balance
- Example: A property worth $900,000 with a $450,000 loan leaves usable equity of ($900,000 x 0.80) minus $450,000 = $270,000
The 80% LVR threshold is the point at which most lenders require LMI. Keeping total borrowings at or below 80% of the property's value means no LMI, which typically saves thousands.
Serviceability is a separate test. The Australian Prudential Regulation Authority (APRA) still expects lenders to assess repayments at your rate plus 3 percentage points. Your income, existing debts, and living expenses all need to clear that bar.
The Repeat Mechanic: Property One Funds Property Two
Once you release usable equity from property one as a deposit, a lender typically funds the remaining 80% of property two as a separate investment loan. If property two also grows, you can later repeat the exercise to fund property three. The deposit for each new purchase comes from equity already sitting in the portfolio rather than fresh cash savings.
A useful rule of thumb: property investors often use the "Rule of Four" to estimate maximum investment property purchase price. This guideline suggests your investment property price should be roughly four times your usable equity, as it covers a 20% deposit with the lender providing 80% finance, plus a buffer for stamp duty, legal fees, and building inspections.
So $270,000 of usable equity could, in principle, support a purchase of around $1,080,000. That is illustrative only. Stamp duty, conveyancing costs, and potential land tax vary by state and need to be factored in before committing.
The Trade-offs: When It Works and When It Doesn't
The strategy has real costs and limits.
What supports it:
- Each property generates rental income that can contribute to servicing the expanded debt. An independent rental appraisal before purchase is important; realistic income figures beat optimistic ones when a lender runs the numbers.
- There is a capital gains tax (CGT) discount of 50% for Australian resident individuals who own an asset for 12 months or more, meaning you pay tax on only half the net capital gain on that asset. This is per the ATO (ato.gov.au). That discount affects the after-tax cost of any future restructuring.
- Note: the 2026-27 Federal Budget announced that, from 1 July 2027, the 50% CGT discount would be replaced with an inflation-based discount and a minimum 30% tax on gains. Investors in new builds can choose the 50% CGT discount or the new arrangements. This is something to discuss with a tax adviser, particularly if you are considering selling or restructuring before that date.
What works against it:
- Each new loan increases total debt and reduces cashflow headroom. A vacancy on any property, or a rate increase, flows through the whole portfolio.
- Having accessible equity does not mean you should use it all. Maintaining buffers for unexpected costs, rental vacancies, or rate rises provides crucial safety margins.
- Lenders assess each new application on current income and existing commitments. Multiple investment loans can reduce the available credit for a subsequent purchase even when equity exists on paper.
The SMSF Angle: A Different Set of Rules
For investors with a Self-Managed Super Fund, property is also an option inside super, but the structure and constraints are meaningfully different.
An SMSF borrows to buy property through a Limited Recourse Borrowing Arrangement (LRBA) under the Superannuation Industry (Supervision) Act. When an SMSF takes out a loan, it must be used to purchase a "single acquirable asset," which is then held in a separate trust, commonly called a bare or holding trust. The "limited recourse" feature means that if the fund defaults on the loan, the lender can only seize the asset purchased with that loan. The lender has no recourse to the SMSF's other assets.
The "sole purpose test" under superannuation law strictly prohibits you, your family, or any related party from living in or renting a residential property owned by your SMSF. Doing so is a major compliance breach with severe ATO penalties.
On deposit and rate requirements: the SMSF needs a minimum 20-30% deposit plus purchase costs from existing super assets. SMSF loans carry a premium over standard investment property rates, typically 1%-2% higher, reflecting the complexity and limited recourse nature of the loan. These figures are indicative at the time of writing; confirm current lender requirements with a broker before proceeding.
One critical contract rule: an SMSF using an LRBA can purchase a completed property or a new build on a single contract covering land and construction together. A crucial limitation is that borrowed funds can only be used to purchase a "single acquirable asset", meaning one loan for one property on a single title. You cannot use an LRBA to buy a block of land and then take out a second loan to fund the construction of a house. The loan must be for the entire, single asset.
The tax treatment inside super is also distinct from personal ownership. In accumulation phase, rental income is taxed at 15%. In pension phase, income and capital gains on assets supporting pension payments are taxed at 0%, up to the Transfer Balance Cap. These rates are per the ATO and apply to complying funds.
Worth knowing: SMSF property is not simply a cheaper version of personal investment property. The compliance overhead, lender pool, and deposit requirements are all higher. The tax environment can be more favourable, but only if the structure is maintained correctly across the life of the loan.
A Worked Example: From One Property to Three
This example is illustrative only. It uses round numbers to show the mechanic, not to project returns.
Year 0. Maria buys a home at $750,000. She pays it down to a $400,000 balance over several years. The property is now independently appraised at $950,000.
- Usable equity: ($950,000 x 0.80) minus $400,000 = $360,000
Year 1. Maria works with a broker and releases $240,000 of usable equity as a deposit for a $1,000,000 investment property (the remaining 20% plus costs). The investment loan is $800,000. She obtains an independent rental appraisal before the purchase settles.
Year 4. Property two has grown. Usable equity on that property is now $180,000 after accounting for the outstanding loan. Maria has also reduced the equity loan slightly. Combined, she has enough usable equity for a deposit on a third property, subject to income serviceability being reassessed.
At each step, the key variables are: the lender's formal valuation (which can differ from an estimate), current income to service the growing debt, and a realistic assessment of rental income versus vacancy risk. None of those variables is guaranteed in advance.
What to Do Next
Get a clear picture of your current equity position. A licensed broker can order a formal bank valuation and calculate your actual usable equity across any properties you hold. Online estimates are a starting point only. Talk to the team at EWC to understand how a property sourcing conversation typically starts.
Check your serviceability before you search. Lenders assess new applications on your full debt and income picture. Knowing your borrowing capacity before shortlisting properties saves time and prevents commitment without certainty. Book a call at elitewealthcreators.com/booking/ to discuss how EWC coordinates with licensed brokers.
Get specialist advice for your structure. If an SMSF is part of the picture, an SMSF specialist accountant and a broker experienced in LRBA lending are both needed before any purchase decision. If you are buying in your personal name, a tax adviser can help you understand how CGT, negative gearing changes from 1 July 2027, and ownership structure interact.
