Why Investment Loans for Holiday Rentals Work Differently

How Lenders Assess Holiday Rental Income

Most lenders discount holiday rental income by 20 to 30 per cent when calculating your borrowing capacity, compared to a standard 20 per cent discount for long-term rental properties. This adjustment reflects higher vacancy rates and seasonal income fluctuations. Some lenders will only recognise holiday rental income if you provide evidence of historical bookings or a professional management agreement, while others may not lend against projected holiday rental income at all for first-time property investors.

Consider a buyer looking at a two-bedroom unit near South Perth foreshore with an expected holiday rental yield. The property might generate $45,000 annually through short-stay bookings, but the lender applies a 30 per cent discount and assesses serviceability based on $31,500 instead. If the buyer also holds a variable rate owner-occupier loan and earns $120,000 per year, the additional servicing buffer of 3.0 percentage points on the investment loan means their total debt-to-income ratio could exceed six times, triggering additional scrutiny under lending limits that took effect in February. The buyer in this scenario might need to reduce the loan amount or increase their deposit to meet serviceability requirements, even though the property's actual rental performance supports the borrowing.

Why Vacancy Rates Matter More for Holiday Properties

Holiday rental properties experience higher vacancy periods than long-term rentals, and lenders factor this into loan serviceability from day one. A property with 40 per cent occupancy across the year might seem viable based on nightly rates, but lenders assess whether you can service the loan during extended gaps between bookings. This becomes particularly relevant if you hold the property on a principal-and-interest loan rather than interest-only, as repayments remain constant regardless of occupancy.

In coastal or tourist-dependent areas, seasonal demand can create three-month stretches with minimal income. A holiday rental in a regional location might generate most of its revenue between December and February, leaving nine months of lower or zero bookings. Lenders recognise this pattern and apply conservative income assumptions, which reduces how much you can borrow compared to a property leased under a fixed 12-month residential tenancy. If you plan to use the property yourself for part of the year, lenders typically will not recognise any rental income for the weeks you occupy it, further reducing assessed income.

Deposit Requirements and LMI on Holiday Rental Loans

Lenders generally require a minimum 20 per cent deposit for holiday rental properties to avoid Lenders Mortgage Insurance, though some will lend at higher loan-to-value ratios if you pay the premium. LMI on an investment loan is calculated on a sliding scale and is higher than the equivalent premium for an owner-occupier loan at the same LVR. The premium is a one-time cost added to the loan amount or paid upfront, and it protects the lender rather than the borrower.

If you already own investment property and want to leverage equity to fund a deposit, the lender will assess your total borrowing capacity across all loans, including the new holiday rental loan. Where your debt-to-income ratio is high, accessing equity might push your application into the discretionary lending category, where approval depends on compensating factors such as a strong repayment history or significant cash reserves. In our experience, buyers using equity from an existing property to fund a holiday rental deposit should confirm serviceability before signing a contract, particularly where rental income from the new property will be heavily discounted.

Interest-Only Loans and Cash Flow Management

Interest-only repayments can improve cash flow in the early years of holding a holiday rental, but fewer lenders offer interest-only periods longer than five years on investment loans, and rates are typically higher than principal-and-interest products. An interest-only loan allows you to manage periods of low occupancy without drawing on savings to cover repayments, but you will still need to demonstrate capacity to service principal-and-interest repayments at the end of the interest-only term.

For holiday rental investors planning to hold the property long-term and build equity through capital growth rather than loan reduction, an interest-only structure can align with that strategy. However, under prudential standards in force since July 2025, lenders apply higher risk weightings to interest-only investment loans, which can affect pricing and approval criteria. Where the interest-only period exceeds five years and the LVR is above 80 per cent, the loan is classified as non-standard, attracting stricter assessment.

Tax Treatment of Holiday Rental Expenses

Interest on borrowings used to purchase a holiday rental property is deductible against rental income, along with other holding costs such as council rates, insurance, property management fees, repairs and depreciation on fixtures. If the property generates a loss after expenses, that loss can be offset against other income for properties held before May 2026 or classified as eligible new builds. For established properties acquired after that date, losses are deductible only against other residential property income from the 2027-28 income year onward, and excess losses are carried forward.

Holiday rental properties also incur costs not typical of long-term rentals, including linen, cleaning between guests, utilities and platform fees for listing services. These are generally deductible where the property is genuinely available for rent and not used predominantly for private purposes. The distinction between a rental property and a holiday home used occasionally by the owner matters for tax purposes. If you occupy the property for more than a minor portion of the year, the Australian Taxation Office may disallow deductions proportionate to private use. Body corporate fees, common in strata-titled holiday properties, are also claimable expenses.

Refinancing an Existing Property to Fund a Holiday Rental

Refinancing your owner-occupier loan or an existing investment property to release equity is one way to fund a deposit on a holiday rental without selling other assets. The refinance process involves a full serviceability assessment, and the lender will consider rental income from the new holiday property under the same discounted assumptions described earlier. If you are moving from a low fixed rate to a higher variable rate during the refinance, your repayments will increase, which reduces borrowing capacity for the new loan.

Where you are refinancing to access equity and the released funds will be used to purchase an income-producing asset, the interest on the additional borrowing is deductible. However, if you refinance for an amount larger than required and use the surplus for private purposes, only the portion of interest attributable to the investment is deductible. Lenders will also reassess your total debt-to-income ratio across all loans, including the proposed holiday rental loan, which may limit how much equity you can access if your income does not support the combined debt.

Choosing Between Variable and Fixed Rates for Holiday Rentals

Variable rate investment loans offer flexibility to make extra repayments and access offset accounts, which can be useful when holiday rental income is irregular. Fixed rate loans provide certainty over repayments for a set period, but typically do not allow offset accounts and restrict extra repayments to a capped amount each year. If you fix the rate and later decide to sell or refinance before the fixed term ends, break costs may apply.

In our experience, investors holding holiday rentals favour variable rates or split loan structures where part of the loan is fixed and part remains variable. A split structure allows you to lock in a portion of your repayments while retaining the flexibility to park surplus rental income in an offset account attached to the variable portion. This approach reduces interest on the variable component during high-occupancy months and provides a buffer during quieter periods. When comparing investment loan options, consider how each product handles irregular income rather than focusing solely on the interest rate.
