The Pros and Cons of Investment Loans for Property

An investment loan lets you borrow against future rental income and capital growth to acquire property you wouldn't otherwise be able to afford outright.

That leverage is powerful, but it comes with strings attached, particularly around tax treatment, serviceability, and the way lenders assess investment borrowing differently from owner-occupier lending. For Belmont residents thinking about adding a second property to the mix or starting a portfolio from scratch, understanding what you gain and what you give up with investment loans is the difference between a strategy that compounds and one that stalls.

Leverage and Borrowing Capacity

An investment loan increases your exposure to the property market without requiring you to save the full purchase price. In Belmont, where many buyers already own a home along High Street or near the waterfront, this typically means releasing equity in that first property to fund a deposit on the next.

Lenders will lend up to 80 per cent of a property's value without requiring Lenders Mortgage Insurance, and sometimes higher if you're prepared to pay the premium. The deposit you need is often sourced from equity in your existing property rather than cash savings. Consider a buyer who owns a home valued at the suburb's current median and has paid down enough of the mortgage to access $100,000 in equity. That buyer can use the equity as a deposit on a rental property without disrupting their household cashflow.

Serviceability is where investment loans differ. Lenders assess your ability to repay based on a buffer rate that sits 3.0 percentage points above the actual loan rate, and they'll only count 80 per cent of expected rental income when calculating your capacity. If the property you're buying is near Belmont Common or within walking distance of the train station, vacancy rates are typically lower, but the lender's serviceability formula doesn't change based on location.

Tax Deductions and the Quarantine Rules

Interest on an investment loan is tax-deductible, along with other holding costs like council rates, insurance, property management fees, and repairs. For properties held before mid-May 2026, losses can still be offset against your salary or other income. For properties acquired after that date, losses are quarantined and can only be offset against other residential property income from the 2027-28 income year onward.

That quarantine changes the cashflow equation. In a scenario where an investor borrows to buy an established unit near Belmont Village and the rental income doesn't cover the interest and holding costs, the shortfall can no longer reduce taxable income from employment. The loss is carried forward and can be used to offset future property income or capital gains, but it doesn't deliver an immediate tax refund. New builds are exempt from the quarantine, which means an investor buying a newly constructed townhouse in Belmont can still deduct losses against salary.

The upside of the deduction is real, but it's not a reason to buy a property that doesn't hold its value. We regularly see investors attracted to high depreciation schedules and forget that depreciation doesn't pay the mortgage if the tenant leaves.

Interest-Only Repayments and Cashflow

Most investment loans start with an interest-only period, typically five years. During that time, your repayment covers only the interest charge, which keeps the monthly cost lower than a principal-and-interest loan on the same amount. The loan balance doesn't reduce, but the rental income often covers or gets close to covering the interest cost.

Interest-only suits investors who want to hold multiple properties or who plan to use surplus cashflow to pay down their owner-occupier mortgage faster. Once the interest-only period ends, the loan reverts to principal and interest unless you apply to extend it. Lenders will reassess your circumstances before approving an extension, and prudential rules treat long-term interest-only loans at higher loan-to-value ratios as non-standard, which can affect pricing.

If you're holding a property in Belmont with reliable rental demand from the hospital precinct or schools in the area, interest-only can make sense as part of a deliberate strategy. It's less useful if you're using it to afford a property that's marginal on serviceability from the start.

Capital Growth Versus Holding Costs

An investment loan only works over time if the property appreciates enough to cover the interest, holding costs, and transaction expenses. Belmont has seen sustained demand due to its proximity to Geelong CBD, the waterfront, and local schools, but no location is immune to flat markets or corrections.

From July 2027, capital gains tax treatment changes for the portion of any gain that accrues after that date. Instead of the 50 per cent discount, investors will index their cost base to inflation and pay a minimum 30 per cent tax rate on real gains. Properties held before July 2027 are taxed under a split system, with pre-July 2027 gains taxed under the old rules and post-July 2027 gains under the new rules. Eligible new builds retain access to the 50 per cent discount as an option, which can make a meaningful difference over a long hold period.

The other side of growth is vacancy. If the property sits empty for extended periods, the holding costs continue but the rental income stops. Belmont's rental market has historically been stable, but an investor buying further out or in an area with higher supply needs to factor in realistic vacancy assumptions when modeling the investment.

Variable Versus Fixed Rates on Investment Loans

Investment loan rates are typically higher than owner-occupier rates, and interest-only loans are priced above principal-and-interest loans. A variable rate gives you flexibility to make extra repayments or refinance without break costs, but it also exposes you to rate increases. A fixed rate locks in your repayment for a set period, which can help with budgeting, but you'll pay a penalty if you want to exit or refinance before the fixed term ends.

Some investors split their loan between variable and fixed, which gives partial protection against rate rises while retaining some flexibility. The right structure depends on your cashflow, your view on rates, and whether you plan to add more properties in the near term. In our experience, investors who lock in a long fixed term without understanding the break cost provisions often find themselves stuck when a better opportunity or a better rate appears.

Portfolio Growth and Debt-to-Income Limits

Building a portfolio means managing serviceability across multiple loans. From February 2026, lenders are restricted in how much they can lend to borrowers with total debt exceeding six times their gross income. The limit applies separately to investment lending and owner-occupier lending, and only 20 per cent of new investment loans at any lender can exceed that six-times threshold in a given quarter.

For a Belmont investor with a household income of $120,000, total borrowing across all properties is capped at $720,000 before hitting that threshold. Some lenders will still go higher, but the pool of willing lenders shrinks, and rates may be less competitive. Investors who want to grow beyond one or two properties need to manage their debt-to-income ratio carefully, which often means paying down loan balances or increasing income before taking on the next purchase.

Access to investment loan options from banks and lenders across Australia means you're not limited to your current bank, but every lender applies the same 3.0 percentage point serviceability buffer and the same debt-to-income assessment framework.

Risks You Don't See Until Later

An investment loan magnifies both gains and losses. If the property falls in value, you still owe the full loan amount, and if you need to sell in a downturn, you may not recover your deposit and transaction costs. If interest rates rise or your income falls, the rental income may not cover the shortfall, and you'll need to find the gap from your own cashflow.

Foreign investment restrictions, tighter lending standards, and changes to tax treatment all shift the landscape over time. We regularly see investors who bought in the early stages of a development, assuming strong capital growth, only to find that oversupply in the area suppressed rents and values for years.

The other risk is liquidity. Property is not a liquid asset, and if you need to access your equity or sell in a hurry, transaction costs and timing can eat into your return. An investment loan is a long-term commitment, and the strategy needs to be resilient enough to handle a few years of poor performance without forcing a sale.
