Investment Property as a High-Income Medical Professional

High-income doctors are well-placed to buy investment property in Australia. Your borrowing capacity is strong, lenders often waive LMI, and investment properties can offset a significant slice of your tax bill through negative gearing and depreciation.

That said, property is not automatically the right move just because you can afford it. Here is what you actually need to think through.

Your Borrowing Capacity Works in Your Favour

Banks treat doctors differently to most borrowers. Many lenders allow up to 90% borrowing without LMI, and some will go to 95%. That means a specialist on $350,000 a year could comfortably borrow $1.5 to $2 million total across their home and investment portfolio, without needing a 20% deposit saved for each purchase.

This opens up markets that are not accessible to most buyers at the same career stage. A GP two years out of vocational training can buy in suburbs that someone on a comparable salary in another profession simply cannot reach.

For a full breakdown of what lenders look at when assessing doctor applications, the property guide for medical professionals covers the key criteria in detail.

Negative Gearing and What It Actually Means

If your investment property costs more to hold than it earns in rent, that loss is deductible against your other income. For a doctor on the top marginal rate (47 cents in the dollar including the Medicare levy), a $30,000 annual shortfall between rent and costs effectively costs you around $16,000 out of pocket.

That is a real benefit, but it only makes sense if the property grows in value enough to compensate for those ongoing losses. Negative gearing is not a tax strategy on its own. It is a tax offset for a growth investment.

A quantity surveyor (QS) report is worth getting on any investment property built after 1985. Depreciation on the building and fittings can add another $5,000 to $15,000 in deductions per year, on top of interest and running costs, with minimal effort on your part.

Capital Gains and the 50% Discount

If you hold the property for more than 12 months before selling, you are eligible for the CGT discount. Only half the capital gain is added to your taxable income for that year.

For a doctor on a high income, this matters a lot. If you sell for a $400,000 gain after five years, you pay tax on $200,000 rather than $400,000. That is a tax saving in the range of $94,000 for someone at the top marginal rate.

The catch is that a large gain in a single year can still push you well above your normal income. Timing a sale for a year when you are on parental leave, working part-time, or transitioning between roles can reduce your effective rate on that gain significantly.

Structuring Your Loans the Right Way

Many doctors hold investment properties on interest-only loans during their peak earning years. The logic: interest payments are fully deductible, while principal repayments are not. Keeping repayments interest-only reduces cash outgoings and maximises the deductible component of your costs.

The risk is that you are not reducing the loan balance, so you are relying entirely on capital growth to build equity.

A common structure is to direct extra repayments toward your owner-occupied home loan, which is not tax deductible, while keeping the investment loan on interest-only. That order of priority makes mathematical sense for anyone in a high tax bracket.

When Investment Property Makes Sense for You

Investment property suits some career stages better than others. A consultant or specialist with a stable base salary, existing home equity, and a clear picture of cash flow requirements is in a stronger position than a registrar still juggling study debts and a variable roster.

Before committing, check:

• Can you service both loans if rates rise by 2%?
• Have you maxed your concessional super contributions? At $30,000 per year, that is a guaranteed 15% tax rate on contributions versus 47% on your marginal income.
• Are you comfortable holding for at least seven to ten years? Short-term property gains after transaction costs and tax rarely stack up.

Investment property and super contributions are not mutually exclusive, but doctors who spread themselves too thin across both without enough cash flow often end up selling at the wrong time.

Key Takeaways

• Doctors can often borrow up to 90% without LMI, giving access to markets most buyers at the same career stage cannot reach
• Negative gearing reduces taxable income in real time, but only makes sense paired with a genuine growth-focused property
• Holding for 12-plus months unlocks the 50% CGT discount, which is significant at the top marginal rate
• A QS report on a newer property adds meaningful depreciation deductions with minimal effort
• Interest-only loans on investment properties combined with principal repayments on your home loan is a tax-efficient structure for high earners
