What Makes an Investment Loan Different from a Home Loan

An investment loan is structured to fund a property you intend to rent out rather than live in. Lenders assess these applications using different serviceability criteria because rental income replaces the owner-occupier commitment to the property as your primary residence. Most lenders will only count 70 to 80 per cent of the expected rental income when calculating your borrowing capacity, which reflects vacancy periods and the risk that tenants may leave or default.

Consider someone who already owns a home in Greystanes and is looking to purchase a unit in Parramatta as a rental. The lender applies a serviceability buffer of at least 3 percentage points above the loan product rate and uses only a portion of the rental income to assess repayment capacity. That person also faces debt-to-income lending limits introduced in February this year, which restrict how much high-DTI lending each bank can approve. In our experience, buyers who understand these limits ahead of time shape their applications to avoid falling into the restricted pool.

The loan amount you can access depends on your current income, existing debts, and the net rental return after the lender's discount is applied. If your borrowing sits at a debt-to-income ratio of 6 times or more, the lender may decline or cap the approval because they have already allocated their quota for high-DTI investor loans.

How Rental Income Is Assessed by Lenders

Lenders do not accept your estimated rental figure without verification. They request a rental appraisal from a licensed property manager or real estate agent, then apply a shading percentage that typically ranges from 20 to 30 per cent. The shaded figure is what counts toward serviceability, not the gross rent.

For a two-bedroom unit near Greystanes Shopping Centre that might rent for $550 per week, a lender applying a 25 per cent shading would assess your rental income at $412 per week. Over a year, that reduces your assessed income by more than $7,000. When combined with the 3 percentage point buffer on interest rates, the gap between what you think you can borrow and what the lender will approve can be significant.

You also need to account for body corporate fees, council rates and landlord insurance in your holding costs. These are deductible against rental income for tax purposes, but lenders include them as ongoing expenses when determining whether you can service the loan.

Deposit Requirements and Loan-to-Value Ratios for Investment Property

Most lenders require a minimum 10 per cent deposit for investment loans, though some will lend at higher loan-to-value ratios if you pay Lenders Mortgage Insurance. LMI becomes mandatory when your LVR exceeds 80 per cent, and the premium is calculated on a sliding scale based on both the loan amount and the LVR.

Investor loans attract higher risk weightings under the current prudential standards, which means lenders hold more capital against them and therefore price them accordingly. At LVRs above 80 per cent, the premium for LMI on an investor loan is higher than it would be for an equivalent owner-occupier loan at the same LVR.

If you already own property, you may be able to leverage equity rather than saving a cash deposit. In a scenario where you own a home in Greystanes with $200,000 in available equity, a lender can use that equity as security for the deposit on your next purchase. You still need to show genuine savings for stamp duty and settlement costs, and the total lending across both properties must meet serviceability tests, but equity release allows you to grow a portfolio without waiting years to accumulate another deposit.

Interest-Only Repayments and Principal-and-Interest Structures

Interest-only repayments reduce your monthly outgoings during the interest-only period, which can improve cash flow and allow you to hold the property through vacancy periods or market downturns. Most lenders offer interest-only terms of up to five years for residential investment loans, after which the loan reverts to principal and interest.

The trade-off is that you do not reduce the loan balance during the interest-only period, so your total interest cost over the life of the loan is higher. An interest-only loan also attracts a higher risk weight under the capital adequacy framework, which may affect the interest rate you are offered or the LVR the lender is willing to approve.

Principal-and-interest repayments build equity over time and typically attract a lower interest rate. For investors who plan to hold the property long-term and are comfortable with higher monthly repayments, principal and interest can reduce the loan balance steadily and lower the total interest paid over the loan term.

Fixed Rate, Variable Rate and Split Loan Structures

A variable rate allows you to benefit from rate cuts and typically includes features such as offset accounts and the ability to make extra repayments without penalty. A fixed rate locks in your repayments for a set period, usually between one and five years, which provides certainty during that time but limits flexibility and may incur break costs if you repay the loan early or refinance before the fixed term ends.

Split loan structures divide your total borrowing between fixed and variable portions, allowing you to lock in part of your repayments while maintaining flexibility on the remainder. In our experience, this approach works well for investors who want rate protection but also want to retain the ability to make extra repayments or access an offset account on the variable portion.

The interest rate you receive on an investment loan is generally higher than the equivalent owner-occupier rate, even at the same LVR and loan amount. Rate discounts are negotiable depending on your deposit size, the total lending relationship, and whether you package other products such as insurance with the lender.

Tax Deductions and Negative Gearing Under the Current and New Rules

For properties you already own or purchased before 7:30pm on 12 May this year, the existing negative gearing rules continue to apply until you sell. If your holding costs, including interest, exceed your rental income, you can claim the net rental loss against your other assessable income such as salary.

For residential investment properties acquired from 7:30pm on 12 May this year onward, new rules take effect from 1 July next year. Net rental losses will be quarantined and can only be offset against other residential rental income or carried forward to offset future rental income or capital gains from residential property. You will not be able to claim those losses against your salary or wages.

The change does not affect properties purchased before the cut-off date, and it does not affect eligible new builds. If you purchase a newly constructed dwelling on previously vacant land, or a property where the number of dwellings has increased, you retain access to negative gearing under the existing rules. A knock-down rebuild that does not add dwellings does not qualify as an eligible new build.

Capital Gains Tax Changes from 1 July Next Year

Gains that accrue before 1 July next year remain subject to the existing 50 per cent CGT discount if you hold the asset for at least 12 months. From 1 July next year, the 50 per cent discount is replaced with cost base indexation and a minimum 30 per cent tax rate on real capital gains for most assets.

If you own a property before 1 July next year and sell after that date, your gain is split. The portion accruing before the change remains eligible for the 50 per cent discount, and the portion accruing after the change is taxed under the new rules. You can obtain a market valuation as at 1 July next year or use an apportionment formula the ATO will publish.

Investors who purchase eligible new build properties retain the option to elect either the 50 per cent discount or indexation with the 30 per cent minimum tax when they sell. This preserves an incentive to invest in new housing supply while removing the discount for established dwellings.

Building a Portfolio That Adapts to Legislative and Market Conditions

The investors we work with in Greystanes are thinking about portfolio growth over decades, not just the next purchase. That means structuring each loan so it does not limit future borrowing capacity and keeping enough flexibility to respond when legislation or market conditions shift.

In practice, this looks like maintaining offset accounts to reduce interest costs without locking funds into the loan, choosing loan structures that allow you to release equity as your properties appreciate, and timing purchases so you acquire properties that qualify as eligible new builds when the tax benefits justify the higher purchase price.

You also need to account for the debt-to-income cap that came into effect in February. If your total lending across all properties pushes your DTI above 6 times your gross income, you may find lenders unable to approve further borrowing even if your serviceability is sound. Structuring loans across different lenders or paying down existing debt before applying for the next loan can keep your options open.

How We Help Greystanes Investors Structure Their Property Finance

We work with investors at every stage, from the first purchase through to portfolio refinancing and equity release. The role of a broker is to match your circumstances and strategy to the lender and loan product that supports what you are trying to achieve, not just to approve the application.

That includes reviewing rental appraisals before you apply, modelling how different repayment structures affect your serviceability for future purchases, and identifying lenders that offer the rate discounts and features that align with your plans. Legislation changes quickly, and lender policies shift even faster. Keeping up with those changes is part of the service.

Call one of our team or book an appointment at a time that works for you. We'll talk through your situation, work out what structure makes sense, and connect you with lenders who understand property investment and are willing to back the strategy you're building.

Frequently Asked Questions

Can I still negatively gear an investment property purchased this year?

Properties purchased on or after 7:30pm on 12 May this year will be subject to quarantining of net rental losses from 1 July next year. Until then, you can claim losses against other income. Properties purchased before that cut-off retain the existing negative gearing treatment.

How much deposit do I need for an investment property loan?

Most lenders require a minimum 10 per cent deposit, though you will pay Lenders Mortgage Insurance if your LVR exceeds 80 per cent. You can also use equity from an existing property as your deposit if you have sufficient equity available and meet serviceability tests.

What is the debt-to-income lending limit for investor loans?

From February this year, each lender can approve no more than 20 per cent of new investor loans at a debt-to-income ratio of 6 times or greater. If your total borrowing exceeds 6 times your gross income, you may find lenders unable to approve further lending even if you can afford the repayments.

Do the new capital gains tax rules apply to properties I already own?

No. The new CGT rules apply only to gains accruing from 1 July next year onward. If you own a property before that date, the portion of any gain accruing before 1 July next year remains eligible for the existing 50 per cent discount.

What qualifies as an eligible new build for negative gearing and CGT purposes?

Eligible new builds include dwellings constructed on previously vacant land and properties where the number of dwellings has increased. Knock-down rebuilds that do not add dwellings and substantial renovations do not qualify.
