Top Strategies to Acquire Multiple Investment Properties

The rules around acquiring multiple investment properties changed fundamentally on 26 June when the Treasury Laws Amendment received Royal Assent. Adelaide investors planning to build a multi-property portfolio now face quarantined losses on properties acquired after May last year, a debt-to-income cap that limits how many lenders will approve, and indexation replacing the 50 per cent capital gains discount from mid-next year. The strategy that worked for the investor who bought three properties between 2018 and 2023 will not work for the investor starting now.

This article sets out how to structure acquisition, borrowing and timing when the objective is to hold multiple rental properties over the medium term.

Structuring Your First Investment Loan After the Negative Gearing Changes

Your first investment loan determines how much serviceability you retain for the second and third. Lenders assess rental income at 80 per cent of the lease amount to account for vacancy and management, then apply a 3 percentage point serviceability buffer on top of the actual rate. Under the debt-to-income cap introduced in February, no more than 20 per cent of a lender's new investor lending can exceed a DTI of 6 times gross income, which means most borrowers will be assessed closer to 5 or 5.5 times.

Consider an Adelaide buyer earning $120,000 who acquires a unit in Prospect at the suburb's current median. With a 20 per cent deposit, the loan amount sits around $400,000. Rental income of $480 per week is assessed at $384 per week after the 80 per cent adjustment. On a variable rate loan with principal and interest repayments, monthly repayments at current rates plus the buffer might total $3,200, leaving roughly $6,800 of the buyer's gross monthly income uncommitted. That uncommitted income becomes the pool from which the second property must be serviced.

If the buyer instead uses an interest only structure for the first five years, monthly repayments drop to around $2,400, preserving an additional $800 per month in serviceability. That difference compounds when applying for the second loan, because lenders assess your ability to service all existing debt plus the new commitment. Interest only investment structures are not appropriate for every borrower, but they are the standard tool for preserving borrowing capacity when the intention is to acquire multiple properties within a short period.

Using Equity Release to Fund the Second Deposit Without Selling

The deposit for the second property usually comes from saved income, released equity, or both. Equity release allows you to borrow against the increased value of your existing property without selling it. Lenders will typically allow you to borrow up to 80 per cent of the current value across all loans secured against that property, meaning if your first investment property has increased in value and your loan balance has reduced, the difference becomes accessible equity.

In our experience, Adelaide investors acquiring a second property within two to three years of the first often find that capital growth has been modest but sufficient to cover part of the deposit. If the Prospect unit purchased for $500,000 is now valued at $530,000 and the loan balance has reduced to $390,000, the available equity at 80 per cent LVR is $424,000 minus $390,000, or $34,000. That amount can be drawn down and combined with savings to fund the deposit and costs on the second purchase.

Two things limit how much equity you can access. The first is the lender's loan to value ratio cap, which for most investment lending sits at 80 per cent without Lenders Mortgage Insurance and 90 per cent with LMI. The second is serviceability. Releasing equity increases your total loan balance, which increases your repayments, which reduces the amount you can borrow on the next property. Expanding your property portfolio requires balancing equity access with serviceability preservation, and the order in which you do things matters.

How the Debt-to-Income Cap Affects Borrowing for Property Two and Three

APRA's debt-to-income cap applies separately to each lender's investor lending portfolio, which means some lenders will have already reached their 20 per cent allocation and others will still have capacity. The practical effect is that lenders who were willing to approve loans at 6 times income or higher before February are now either declining applications above that threshold or requiring compensating factors such as a larger deposit, lower LVR, or evidence of other assets.

For a buyer on $120,000 gross income, a DTI of 6 times allows total borrowing of $720,000 across all investment loans. If the first property loan is $400,000, the second can be $320,000 before hitting the cap. That assumes the lender is still willing to lend above the DTI threshold at all. In practice, most lenders are now assessing investor applications closer to 5 or 5.5 times income, which would reduce the total available borrowing to $600,000 to $660,000.

The cap does not apply to new builds, which creates a structural advantage for investors acquiring newly constructed properties. A knock-down rebuild that does not increase the dwelling count is not exempt, but a new dwelling on previously vacant land is, as is a development that increases the number of dwellings on the site. Investors planning to acquire multiple properties over the next two to three years should consider whether at least one of those purchases qualifies as a new build, because doing so removes that loan from the DTI calculation and preserves capacity for subsequent purchases.

Fixed Rate or Variable Rate Loans When Acquiring Multiple Properties

Variable rate loans give you flexibility to make additional repayments, redraw funds, and refinance without break costs. Fixed rate loans lock in your repayment amount for a set period, which can be useful if you want certainty over cash flow while acquiring the second or third property, but they come with restrictions on extra repayments and penalties if you exit early. Most lenders cap additional repayments on fixed rate loans at $10,000 to $30,000 per year, and if you need to refinance your investment loan or sell before the fixed term ends, you will be liable for break costs.

Investors acquiring multiple properties within a short period usually favour variable rate products or a split structure that keeps at least 50 to 70 per cent of the total borrowing on variable terms. That preserves the option to refinance part of the portfolio if a lender offers better serviceability treatment or a lower rate, and it allows you to redirect surplus cash flow into offset accounts rather than locking it inside the loan.

Rate discounts on investment loans depend on the loan amount, LVR, and your overall relationship with the lender. A borrower with two properties and $800,000 in total lending will typically receive a larger discount than a borrower with one property and $400,000, but only if both loans are held with the same lender. Consolidating your lending with one institution can improve your rate, but it also concentrates your exposure. If that lender tightens serviceability or changes their appetite for investor lending, you may find it difficult to access further credit when you are ready to acquire the third property.

Negative Gearing After July 2027 and the Impact on Portfolio Growth

From 1 July 2027, net rental losses on residential properties acquired after 7:30pm on 12 May 2026 cannot be offset against salary or other non-residential income. Losses are quarantined and can only be used against future rental income or capital gains on residential property. Properties acquired before that time, including those under contract before the announcement, remain fully negatively geared under the existing rules.

The quarantine does not prevent you from acquiring multiple properties, but it changes the cash flow profile. A property generating a $5,000 annual loss previously reduced your taxable income by that amount, delivering a tax refund if you were on a marginal rate of 37 per cent or higher. After July next year, that loss is carried forward and only becomes useful when you have positive rental income from another property or when you sell and realise a capital gain. If you acquire three properties and all three are negatively geared, the losses accumulate but deliver no immediate tax benefit.

The carve-out for new builds is permanent. A newly constructed dwelling on previously vacant land, or a development that increases the dwelling count, remains fully negatively geared even if acquired after the cut-off date. That creates a structural cash flow advantage for investors focused on new housing stock, particularly if they are acquiring multiple properties and want to preserve the immediate tax deduction.

Timing Acquisitions to Manage Settlement Risk and Lender Appetite

Lenders assess borrowing capacity at the time of application, not at the time of pre-approval. If you receive pre-approval for your second investment property in August and settle in November, the lender will reassess your income, existing commitments and serviceability before final approval. If your circumstances change, or if the lender's credit policy tightens in the interim period, the approval can be withdrawn.

Settlement periods in Adelaide typically run 60 to 90 days for established properties and 12 to 24 months for off-the-plan purchases. Investors acquiring multiple properties within a two-year window need to sequence their purchases so that settlement dates do not overlap, because most lenders will not approve a second application while a first purchase is still pending settlement unless you can demonstrate capacity to service both loans simultaneously from the date of the first application.

As an example, a buyer who applies for a loan on an apartment in Bowden in August, with settlement scheduled for October, can apply for a second loan in November once the first property has settled and the rental income is being received. If they had instead purchased off-the-plan with settlement in 18 months, they would need to wait until that settlement completes before applying for the second loan, or demonstrate that they can service both properties from the date of the first application without relying on rental income from the first property. The latter is rarely feasible for borrowers relying on salary income alone.

Selecting Investment Loan Products That Support Portfolio Lending

Not all lenders treat portfolio investors the same way. Some assess each property in isolation, applying the 80 per cent rental income assumption and the serviceability buffer to every loan without recognising that expenses such as property management and insurance do not scale linearly. Others apply portfolio serviceability, which recognises that a borrower with three properties and $900,000 in total lending is managing a consolidated income and expense position, not three separate loans.

Lenders who offer portfolio serviceability will often assess your total rental income and total loan repayments together, rather than assessing each loan in isolation and stacking the results. That approach can increase your borrowing capacity by 10 to 20 per cent when applying for your third or fourth property, because it avoids double-counting fixed costs such as property management fees, insurance, and rates.

Some lenders also offer cross-collateralisation, where multiple properties are used as security for a single loan facility. This can reduce documentation and sometimes improve your interest rate, but it also means you cannot sell one property without the lender's consent to release it from the security pool. Cross-collateralisation works when you intend to hold all properties long-term and refinance the entire portfolio together, but it creates friction if you want to sell one property to fund another or to release equity selectively.
