Investment Risk Assessment for Maxillofacial Surgeons

Investment Risk Assessment Depends on Occupation, Income Structure and Property Type

Lenders assess investment lending risk using standardised credit risk frameworks that assign higher capital costs to investor loans than owner-occupied lending. As a maxillofacial surgeon, your income profile, multiple revenue streams and capacity to service debt at higher test rates influence how much you can borrow and which loan structures you can access. The assessment includes your existing debt, the rental income the property will generate, and whether the loan will be interest only or principal and interest.

Consider a maxillofacial surgeon earning $450,000 annually through a combination of hospital sessions, private billings and consulting fees. She applies for an investment loan to purchase a two-bedroom apartment at the current median in an inner-city Brisbane precinct. The lender assesses serviceability at the loan product rate plus a 3.0 percentage point buffer, as required under APRA prudential standards. Her existing home loan, car finance and practice equipment leases are included in the debt assessment. Rental income from the apartment is included at 80 per cent of the market rent to account for vacancy and management costs. The lender calculates a maximum borrowing amount based on her net income after tax, existing commitments and the buffered rate. In this scenario, she qualifies for an 80 per cent loan to value ratio without requiring Lenders Mortgage Insurance because her occupation attracts a professional exemption from several lenders.

Debt-to-Income Limits Apply Separately to Investor Lending

APRA introduced a debt-to-income lending limit from 1 February 2026, requiring that no more than 20 per cent of new investor loans and 20 per cent of new owner-occupier loans be made to borrowers with a total DTI ratio of six times or greater. The limit applies separately to each portfolio within each bank. If your total borrowings across all home loans, including your own residence and any investment properties, exceed six times your gross annual income, you fall within the high DTI category. Banks can still lend to you, but they allocate those approvals from a limited quarterly quota.

A surgeon with gross income of $400,000 and total borrowings of $2.5 million across an owner-occupied loan and two investment loans has a DTI of 6.25. A third investment loan application will be assessed within the high DTI allocation. The bank may approve the loan if the application meets all other credit criteria and the institution has capacity remaining in that quarter's allocation. If the quota is exhausted, the application may be declined or deferred to the following quarter. Some banks manage their high DTI allocation more conservatively than others, particularly late in a quarter.

Interest Only Periods Reduce Holding Costs but Increase Risk Weighting

Interest only loans allow you to pay only the interest portion of the loan for a set period, typically one to five years, reducing your monthly repayments and maximising the tax deduction on interest. Lenders classify interest only investment loans as higher risk under APS 112, which means they attract higher risk-weighted capital requirements and may be priced at a higher rate than principal and interest loans. The interest only period must be specified in the loan contract. If the LVR exceeds 80 per cent and the contractual interest only period is greater than five years or unspecified, the loan is classified as non-standard and attracts a significantly higher risk weight.

In our experience, surgeons purchasing investment property to generate rental income and negative gearing benefits often prefer interest only repayments to preserve cash flow for other investments or to service existing debt. The reduction in monthly outgoings can be several hundred dollars per month on a loan of $600,000. At the end of the interest only period, the loan reverts to principal and interest repayments unless you negotiate a further interest only extension or refinance the investment loan.

Negative Gearing Rules Changed from 12 May 2026

Negative gearing allows investors to deduct rental property losses, including interest and holding costs, against other income such as salary. Under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, losses from established residential investment properties acquired after 7:30pm AEST on 12 May 2026 can only be offset against income from residential properties, including capital gains on residential property, from the 2027-28 income year onwards. Excess losses can be carried forward. Properties held at 12 May 2026, including those under contract at that time, retain full negative gearing against all income until sold. Eligible new builds acquired after 12 May 2026 also retain full negative gearing.

This changes the risk assessment for investment lending because the after-tax cost of holding an investment property acquired after 12 May 2026 is higher for borrowers who do not have other residential property income to offset losses. Lenders do not directly assess your tax position when calculating serviceability, but the legislative change influences the attractiveness of certain property types. New build apartments and townhouses now carry a legislated tax advantage over established property. A maxillofacial surgeon considering a second or third investment property who does not already hold investment property may find it more difficult to build a diversified portfolio of established dwellings because losses from each property can only be pooled with income from other residential properties rather than offset against surgical income.

Capital Gains Tax Treatment Splits at 1 July 2027

From 1 July 2027, capital gains on residential investment property are taxed differently depending on when the gain accrued. Gains accruing before 1 July 2027 remain eligible for the 50 per cent CGT discount if the property is held for more than 12 months. Gains accruing from 1 July 2027 are taxed using cost base indexation in line with inflation and a 30 per cent minimum tax rate on real gains. Investors who sell property after 1 July 2027 must apportion the gain between the two periods, either by obtaining a market valuation at 1 July 2027 or using an ATO apportionment formula. Eligible new builds offer a choice at sale between the 50 per cent discount and the new indexed treatment.

Lenders do not assess future capital gains when approving an investment loan, but the tax treatment influences your long-term investment strategy and your capacity to leverage equity from the property. If you plan to hold an investment property for ten to fifteen years and then sell to fund retirement or reinvest, the tax treatment of the capital gain directly affects your net proceeds. The indexed treatment may benefit high-income earners in low-inflation environments, while the 50 per cent discount may be preferable where inflation is high or the property is held for a shorter period. This decision point is part of the broader investment property strategy that feeds into your borrowing structure.

LVR and Loan Amount Influence Product Availability

The loan to value ratio is the loan amount divided by the property value. An LVR of 80 per cent or below generally avoids Lenders Mortgage Insurance and attracts the lowest risk weighting under APS 112. Maxillofacial surgeons often qualify for LMI waivers at LVRs up to 90 or 95 per cent with selected lenders, but those waivers are more commonly available for owner-occupied lending than for investment loans. Investment loans at LVRs above 80 per cent generally require LMI, which is a one-off premium calculated on a sliding scale based on the loan amount and LVR. Some lenders cap investment loan LVRs at 90 or 95 per cent regardless of occupation.

Consider a surgeon purchasing an investment property with a 10 per cent deposit. The LVR is 90 per cent. The lender applies LMI, which might add $15,000 to $25,000 to the upfront cost depending on the loan amount and the insurer's premium table. The LMI premium can be capitalised into the loan amount, increasing the LVR slightly, or paid upfront. State stamp duty may apply to the premium. The higher LVR also attracts a higher risk weight under APS 112, which may translate to a slightly higher interest rate or a reduced maximum loan amount due to serviceability constraints at the buffered rate.

Rental Income Is Shaded to Account for Vacancy and Costs

Lenders include rental income in the serviceability assessment but apply a shading factor, typically 20 per cent, to account for periods when the property is vacant, tenant arrears, and management and maintenance costs. If the market rent for an investment property is $600 per week, the lender includes $480 per week in the income calculation. Some lenders apply a higher shading factor of 25 per cent for certain property types or locations. Body corporate fees, council rates, insurance and property management fees are treated as ongoing expenses and reduce the net income available to service the loan.

We regularly see scenarios where a surgeon assumes the rental income will fully offset the loan repayments, only to discover during the application that the lender's shaded rental income and the buffered assessment rate produce a shortfall that must be serviced from other income. The rental yield, expressed as annual rent divided by property value, varies significantly across property types and locations. A two-bedroom apartment in an inner-city Brisbane precinct might yield 4.0 to 4.5 per cent, while a three-bedroom house in an outer suburb might yield 3.5 to 4.0 per cent. Higher yields improve serviceability but do not always correlate with capital growth.

Foreign Investment Restrictions Apply to Temporary Residents

Foreign persons, including temporary residents, are generally banned from purchasing established residential dwellings in Australia from 1 April 2025 to 30 June 2029. Temporary residents can still apply for Foreign Investment Review Board approval to purchase new dwellings or vacant land. Permanent residents and New Zealand citizens are exempt. If you are a temporary resident or hold a visa that does not grant permanent residency, you cannot purchase an established investment property without FIRB approval, which is unlikely to be granted unless the investment significantly increases housing supply or falls within another narrow exception. Maxillofacial surgeons on specialist pathway visas or temporary skilled visas should confirm their residency status and FIRB obligations before entering a contract.

Variable and Fixed Rates Carry Different Risk Profiles

Variable rate investment loans allow you to make additional repayments and access offset accounts, and the rate moves in line with the lender's pricing decisions. Fixed rate loans lock in a rate for one to five years but typically prohibit additional repayments above a small annual threshold and do not offer offset accounts. Breaking a fixed rate loan before the end of the fixed term may trigger break costs, calculated based on the difference between the fixed rate and the lender's current cost of funds. Some borrowers split their loan between variable and fixed portions to balance rate certainty with flexibility.

Investment loan rates are typically 0.3 to 0.6 percentage points higher than owner-occupied rates at the same LVR and loan amount, reflecting the higher risk weight under APS 112. Some lenders offer rate discounts for high-income professionals, but those discounts are more commonly available for owner-occupied lending. When comparing investment loan options, the rate differential between variable and fixed, and between lenders, can influence your total interest cost over the life of the loan and your capacity to leverage equity for further property purchases.

Multiple Properties Compound Serviceability Assessment

Each additional investment property adds rental income and debt servicing obligations to your overall financial position. Lenders assess your capacity to service all existing and proposed debt at the buffered rate, including your owner-occupied home loan, any investment loans, car loans, practice loans, credit card limits and other commitments. As your portfolio grows, the cumulative effect of shaded rental income, buffered assessment rates and existing debt reduces your available borrowing capacity. Some lenders apply portfolio lending policies that cap the number of investment properties or the total investment lending exposure to a single borrower.

A maxillofacial surgeon with two existing investment properties, each generating $500 per week in rent, applies for a third investment loan. The lender includes 80 per cent of $1,000 per week from the two existing properties and 80 per cent of the expected rent from the proposed property, totalling $1,200 per week in shaded rental income. The lender also includes the repayments on three investment loans at the buffered rate, plus the repayments on the surgeon's own home loan, car loan and credit card limit. If the combined debt servicing at the buffered rate exceeds the surgeon's net income plus shaded rental income, the application is declined or the loan amount is reduced. This is where expanding your property portfolio requires a detailed understanding of how lenders aggregate income and debt across multiple properties.

Your ability to structure investment loans in a way that aligns with APRA prudential requirements, DTI limits, tax legislation and your broader financial objectives depends on understanding how lenders assess risk at the application stage. The framework applies to all borrowers, but the way it interacts with your income profile, existing debt and the specific property you are purchasing creates a unique risk assessment for each application.
