How Investment Loans Differ From Home Loans
Investment loans are assessed on rental income, carry higher interest rates than owner-occupied products, and allow interest-only repayment periods to support cash flow.
Lenders treat investor borrowing differently because the property does not serve as your residence. Rental income offsets borrowing costs, but lenders typically apply a discount of 20 per cent to that income when calculating servicing. If a property generates $2,000 per month in rent, the lender will assess it at $1,600. This adjustment accounts for periods when the property sits vacant or requires maintenance.
Variable rates for investment products currently sit between 0.3 and 0.5 percentage points above owner-occupied rates. Fixed rate options are available, though fewer lenders offer competitive fixed terms for investment purposes. Interest-only periods, usually set at five years, reduce monthly repayments during the growth phase of a portfolio. After the interest-only term concludes, the loan reverts to principal and interest unless refinanced or restructured.
Loan to value ratio affects both your deposit requirement and whether Lenders Mortgage Insurance applies. Most lenders cap investment lending at 90 per cent LVR for single properties, though 80 per cent is standard for portfolio lending. LMI becomes payable above 80 per cent and the premium increases sharply as LVR rises.
Why South Morang Appeals to Portfolio Investors
South Morang offers median dwelling prices lower than inner-ring suburbs, proximity to the metropolitan train terminus, and strong rental demand from families and commuters.
The suburb sits at the northern extent of Melbourne's train network, with services running to the city via Mernda. That connectivity attracts renters who work in the CBD but prefer larger homes and lower rents than inner suburbs command. Families make up a significant portion of tenants, drawn by schools, parks including Hawkstowe Park and Mill Park Lakes, and the Plenty Valley shopping precinct.
Property prices in South Morang remain below the metropolitan median, which allows investors to enter the market with a smaller deposit or acquire multiple properties within a set borrowing limit. The area has seen consistent residential development over the past decade, adding supply but also infrastructure including upgraded roads and community facilities. Rental yields tend to sit above the Melbourne average due to the combination of lower purchase prices and sustained tenant demand.
Investors building a portfolio often select one or two properties in growth corridors like South Morang alongside holdings in more established suburbs. The strategy balances capital growth potential with rental return.
Portfolio Lending and How Lenders Assess Multiple Properties
Portfolio lending refers to financing arrangements where an investor holds two or more investment properties, and lenders assess the combined exposure rather than each loan in isolation.
Once you own a second investment property, most lenders will review your entire portfolio when you apply for additional finance. Serviceability becomes more complex because each property carries holding costs, vacancy risk, and maintenance obligations. Lenders apply the serviceability buffer to the total debt, meaning your income must support all existing loans plus the proposed borrowing at a rate three percentage points above the actual product rate.
Debt-to-income caps introduced in early 2026 also apply. Lenders may fund up to 20 per cent of new investor loans at a DTI of six times or greater, but the majority of lending must sit below that threshold. If your combined investment and owner-occupied debt reaches six times your gross annual income, you may need to approach a second lender or reduce the loan amount.
Cross-collateralisation is a structure where multiple properties secure a single loan facility. It simplifies administration but ties your properties together, meaning you cannot sell or refinance one without the lender's consent on the entire portfolio. Most brokers recommend separate loans for each property to preserve flexibility. Traj Finance structures portfolios with this principle in mind, allowing clients to refinance individual holdings or release equity without disrupting the rest of their investments.

Using Equity to Fund Your Next Investment Property
Equity release allows you to borrow against the value of an existing property without selling it, using the funds as a deposit for the next acquisition.
Consider an investor who purchased a home in South Morang five years ago for $550,000 and now holds equity of $250,000 after paying down the loan and benefiting from price growth. At 80 per cent LVR, the lender will allow total borrowing of 80 per cent of the property's current value. If the property is now worth $700,000, the maximum loan is $560,000. With an existing mortgage of $450,000, the investor can access $110,000 in usable equity. That amount covers a 20 per cent deposit on a $550,000 investment property, avoiding LMI and leaving a buffer for transaction costs.
Lenders assess equity release applications using the same serviceability rules as a new loan. The additional borrowing increases your monthly repayment, and that higher repayment must fit within your income and debt ratios. Rental income from the property you are purchasing will offset some of this cost, but lenders apply the 20 per cent discount discussed earlier.
Refinancing an existing loan to access equity can also secure a lower rate or better loan features if your current product no longer suits your strategy. Investors often refinance their owner-occupied home to release equity, then apply that equity as a deposit on an investment property while keeping the loans separate.
Investment Loan Features That Support Portfolio Growth
Offset accounts, redraw facilities, and the ability to split loans between fixed and variable rates provide flexibility as your portfolio expands.
An offset account linked to an investment loan reduces the interest charged without affecting the deductibility of that interest. If your loan balance is $400,000 and you hold $50,000 in the offset, you pay interest on $350,000. The full $400,000 remains deductible because the loan amount has not changed. Offset accounts suit investors who accumulate cash between acquisitions or hold funds for upcoming maintenance.
Redraw facilities allow you to access any extra repayments you have made above the minimum. This can be useful if you make principal repayments during the interest-only period and later need those funds for another deposit. However, redrawing principal from an investment loan may affect the deductibility of future interest if the redrawn funds are used for private purposes. The distinction between offset and redraw matters for tax treatment, and investors should seek advice before accessing either facility.
Splitting a loan between fixed and variable rates allows you to lock in part of your borrowing while retaining flexibility on the remainder. Some investors fix 50 to 70 per cent of the loan to manage repayment certainty, leaving the rest on a variable rate to allow extra repayments or offset benefits.
Negative Gearing and the Changes Taking Effect in Mid-2027
Negative gearing allows investors to offset rental losses against other income, reducing taxable income, but new rules will quarantine those losses for properties acquired after May 2026 unless the property is an eligible new build.
Under current rules, if your investment property costs $30,000 per year to hold and generates $24,000 in rent, the $6,000 loss can be deducted against your salary or other income. From 1 July 2027, that loss can only be offset against other residential rental income or carried forward to offset future rental profits or capital gains. The change applies to properties acquired from 7:30pm on 12 May 2026 onward, with a transitional period until 30 June 2027.
Properties purchased before that date, including those under contract at the time, remain eligible for negative gearing under the existing rules. If you are building a portfolio and acquired your first property before May 2026, that property retains full negative gearing benefits even as you add newer properties that do not.
Eligible new residential dwellings continue to qualify for negative gearing under the old rules. This includes properties built on previously vacant land and developments that increase the number of dwellings on a site. A knock-down rebuild that replaces one house with another does not qualify unless it results in multiple dwellings. For investors focused on portfolio growth, this creates an incentive to consider new builds or off-the-plan purchases, particularly in areas like South Morang where residential development continues.
How Capital Gains Tax Rules Are Changing for Investment Properties
From 1 July 2027, the 50 per cent CGT discount for individuals will be replaced with cost base indexation and a minimum 30 per cent tax rate on real gains for affected properties, though gains accrued before that date remain under current rules.
Under the current system, if you sell an investment property and realise a capital gain of $200,000, you include $100,000 in your taxable income after applying the 50 per cent discount. The new rules index your cost base to inflation, reducing the taxable gain, but apply a minimum 30 per cent tax rate to the indexed gain. The transitional design means gains that accrued before 1 July 2027 are not affected. If you purchased a property in 2024 and sell it in 2029, only the gain attributable to the period after 1 July 2027 falls under the new rules.
Eligible new builds receive an election between the 50 per cent discount and the indexed cost base with the minimum rate. This allows investors in new property to choose the most favourable treatment depending on their circumstances.
The changes do not affect the main residence exemption, and they do not apply retrospectively to properties held before the announcement. Investors with existing portfolios should review their holding strategy and consider whether disposing of certain properties before the rules take effect aligns with their financial position. Property investors planning acquisitions after May 2026 will need to model the tax outcome under both the old and new regimes to understand the long-term impact on returns.
Structuring Loans to Preserve Deductibility and Flexibility
Separate loan accounts for each property, dedicated offset accounts, and clear separation of investment and private borrowing ensure interest deductions remain intact and properties can be managed independently.
Mixing investment and private borrowing within a single loan facility creates problems when the ATO reviews your deductions. If you take out a loan to purchase an investment property, then redraw $20,000 for a family holiday, the interest on that $20,000 is no longer deductible. Keeping each investment property on its own loan account, with its own offset and transaction account, removes ambiguity.
Cross-collateralisation, where a lender holds multiple properties as security for a single loan, can limit your ability to sell or refinance. If one property underperforms or you wish to divest it, the lender may require you to refinance the entire portfolio or reduce the loan balance before releasing that property. Separate loans with separate security allow you to act on individual properties without affecting the rest of your holdings.
Investors refinancing an owner-occupied loan to release equity should split the new borrowing into two accounts. One account represents the original owner-occupied debt, the other the equity release used for investment purposes. Interest on the investment portion remains deductible, while interest on the owner-occupied portion does not. Lenders and brokers can structure this at the time of application, but it requires clarity about the purpose of each dollar borrowed.
Applying for an Investment Loan When You Already Hold Property
Lenders assess your current debt, rental income, living expenses, and the proposed property's serviceability, with particular attention to whether the new loan pushes your DTI above the regulatory threshold.
A second or third investment loan application requires updated income verification, rental statements for existing investment properties, and details of any owner-occupied debt. Lenders will request lease agreements or property management statements showing rent received over the past three to six months. They apply the 20 per cent discount to that income, then calculate whether your total income, including salary and net rental income, can service all existing and proposed loans at the buffered rate.
Your living expenses also come under closer scrutiny. The Household Expenditure Measure, used by most lenders, sets a minimum figure based on household size and income. If your actual expenses exceed the HEM benchmark, lenders use the higher figure. As your portfolio grows and your income rises, the HEM floor also increases, which can reduce borrowing capacity even if your rental income has improved.
Debt-to-income caps mean lenders will calculate your total debt divided by your gross annual income. If that ratio exceeds six, the loan may be declined or require manual review. Some lenders have appetite for higher DTI ratios within their 20 per cent allowance, but competition for that allocation is high. Working with a broker provides access to lenders whose portfolio policies align with your situation. Borrowing capacity modelling should be completed before you make an offer on a property, particularly if you are approaching or exceeding a DTI of six.
When to Refinance Your Investment Portfolio
Refinancing makes sense when you can secure a lower rate, access better loan features, release equity for further investment, or consolidate loans for simpler management without cross-collateralisation.
Interest rate discounts have widened between lenders in recent years. A loan taken out three years ago may carry a rate 0.4 to 0.6 percentage points higher than a new loan with the same lender or a competitor. On a $500,000 loan, a 0.5 percentage point reduction saves roughly $2,500 per year in interest. Refinancing costs, including application fees, valuation fees, and discharge fees from the old lender, typically total $1,500 to $3,000 per property. The saving usually justifies the cost within the first year.
Releasing equity through refinancing allows you to fund the next acquisition without selling an existing property. If your portfolio has grown in value or you have paid down principal, refinancing to 80 per cent LVR across all properties can unlock significant equity while keeping LMI off the table.
Consolidating multiple loans under a single lender can simplify administration, but only if the loans remain separate. Some lenders offer portfolio discounts, reducing the interest rate as the total debt increases. This differs from cross-collateralisation because each loan retains its own account and security, but the lender provides a rate benefit in exchange for holding the entire portfolio. Not all lenders offer this structure, and it requires careful comparison to ensure the rate discount outweighs any loss of flexibility.

Frequently Asked Questions
How much deposit do I need for an investment property if I already own my home?
You can use equity from your existing property as the deposit, avoiding the need for cash savings. Lenders typically allow you to borrow up to 80 per cent of your current property's value, and the difference between that amount and your existing loan becomes available equity.
What is the debt-to-income cap for investment loans?
Lenders may approve up to 20 per cent of new investor loans at a DTI of six times gross annual income or higher, but most lending must sit below that threshold. If your total debt exceeds six times your income, you may face declined applications or need to approach a different lender.
Does negative gearing still apply to investment properties purchased now?
Properties acquired from 7:30pm on 12 May 2026 onward will have rental losses quarantined from 1 July 2027, unless they are eligible new builds. Properties purchased before that date continue under existing negative gearing rules.
Should I fix or keep my investment loan on a variable rate?
A split structure, fixing part of the loan while leaving the rest variable, provides repayment certainty and flexibility. Variable rates allow offset accounts and extra repayments, while fixed rates lock in your cost for a set period.
Can I refinance one property in my portfolio without affecting the others?
Yes, if each property is held on a separate loan with separate security. Cross-collateralised loans require lender consent to refinance or sell any property in the group, which is why most brokers recommend keeping loans separate from the outset.
