Unlock the Secrets to Funding Your Holiday Rental

What Makes a Holiday Rental Investment Loan Different

Lenders treat holiday rental properties differently to standard residential investment properties because rental income can vary significantly between peak and off-peak seasons. Most lenders will apply a lower rental assessment rate to holiday properties, typically shading your projected income by 20 to 30 per cent to account for vacancy periods and seasonal fluctuations. Some lenders won't accept holiday rental income at all for serviceability, which means you'll need to service the loan entirely from your own employment or business income.

Consider a buyer looking at a coastal property they plan to rent out short-term during summer and shoulder seasons. If the property generates $45,000 in rental income over the year, the lender might only recognise $31,500 to $36,000 of that income when calculating borrowing capacity. The buyer needs enough personal income to cover the shortfall, particularly during winter months when the property may sit vacant or achieve much lower nightly rates. In this scenario, the buyer had a household income of $140,000 and was servicing the investment loan on a principal and interest basis, which gave the lender confidence that repayments could be met regardless of occupancy.

Deposit and Equity Requirements for Holiday Rental Finance

You'll generally need a minimum 20 per cent deposit for any investment property loan. Some lenders will lend at higher LVR levels if you're willing to pay LMI, but borrowing above 80 per cent LVR for a holiday rental is uncommon because of the income volatility and serviceability constraints. If you're using equity from your home to fund the deposit, the lender will assess both your existing home loan and the new investment loan together under the 3.0 percentage point serviceability buffer that applies to all new borrowing.

Where the property is in a regional or coastal location with limited comparable sales data, some lenders will apply conservative valuation approaches or require a full onsite inspection rather than accepting a desktop valuation. The value assigned by the lender's valuer determines your actual LVR, not the purchase price you've agreed to pay.

How Lenders Assess Rental Income from Short-Term Letting

Rental income from a holiday property is harder to verify than long-term residential rental income. Most lenders will ask for evidence of actual bookings if the property is already tenanted, or a rental appraisal from a local holiday letting agent if you're purchasing vacant. The appraisal needs to show weekly rates across different seasons and an estimated occupancy rate based on comparable properties in the area.

Lenders that do accept holiday rental income for serviceability will typically apply a shading percentage on top of the usual vacancy allowance. For a standard long-term rental, a lender might shade rental income by 20 per cent. For a holiday rental, that shading can increase to 30 per cent or more, depending on the location and the strength of your other income sources. If you're relying solely on rental income to service the loan without substantial wage or salary income, your borrowing capacity will be materially lower than it would be for a comparable long-term investment property.

Interest-Only Versus Principal and Interest Repayments

Many property investors choose interest-only repayments to maximise cash flow and tax deductions, particularly where the strategy involves holding the property for capital growth rather than paying down debt. Interest-only periods are typically available for up to five years on investment loans, after which the loan reverts to principal and interest unless you apply to extend the interest-only term.

For holiday rental properties, an interest-only structure can help manage cash flow during low-occupancy months, but you need to demonstrate to the lender that you can service the loan on a principal and interest basis from day one. Lenders assess serviceability at the higher principal and interest repayment rate even if you select interest-only, and they apply the 3.0 percentage point buffer on top of that. If your income is borderline, opting for principal and interest repayments from the outset can sometimes improve your approval prospects because it reduces the lender's perceived risk.

Variable Rate or Fixed Rate for Holiday Rental Loans

Both variable and fixed rate options are available on investment loans. A variable rate gives you flexibility to make extra repayments without penalty and access to any offset account linked to the loan, which can be useful if rental income fluctuates and you want to park surplus cash to reduce interest. A fixed rate locks in your repayment amount for a set period, which can help with budgeting if you're managing seasonal income.

Some investors split their loan between variable and fixed portions to balance certainty with flexibility. If you fix your rate and then want to exit the loan or refinance before the fixed term ends, break costs may apply depending on rate movements. For holiday rental properties where you might want to sell or refinance within a few years, keeping at least part of the loan on a variable rate preserves your options.

Tax Treatment and Deductibility of Investment Loan Interest

Interest on an investment loan used to purchase a holiday rental property is generally deductible against your rental income, along with other holding costs such as council rates, insurance, property management fees, body corporate levies if applicable, and repairs. If your deductible expenses exceed your rental income in a financial year, you can offset that loss against your other income, including wages, provided the property was acquired on or before 12 May 2026 or qualifies as an eligible new build.

For properties acquired after 12 May 2026 that are not eligible new builds, losses from the 2027-28 income year onward can only be offset against other residential property income, not against salary or wages. Losses can be carried forward to future years. These rules apply to holiday rental properties in the same way as long-term rentals. The tax treatment of capital gains also changed from 1 July 2027, with cost base indexation and a 30 per cent minimum tax rate replacing the 50 per cent CGT discount for gains accruing after that date, unless the property is an eligible new build.

Managing Vacancy Periods and Seasonal Cash Flow

Holiday rental properties often have high occupancy during summer and school holidays, then sit vacant or achieve much lower rates during off-peak months. Lenders are aware of this pattern and will factor it into their assessment, but you also need a cash flow plan to cover loan repayments, strata levies, insurance and other fixed costs during the low season.

Some investors set aside a portion of peak-season income into an offset account to cover expenses during quiet months. Others service the loan entirely from employment income and treat rental income as additional cash flow when it arrives. Your lender will want to see that you have a buffer in place, particularly if you're borrowing at a high LVR or your personal income is only just sufficient to meet serviceability.

Choosing the Right Loan Structure and Lender

Not all lenders assess holiday rental income in the same way. Some will accept short-term rental income with standard shading, others apply heavier discounts, and a few won't recognise it at all. If you're purchasing in a high-demand holiday location with strong year-round occupancy, it's worth speaking to a broker who can match you with a lender that takes a more favourable view of that income type.

Loan features such as offset accounts, redraw facilities and the ability to make extra repayments can add value depending on your strategy. An offset account linked to your investment loan reduces the interest you pay without affecting the deductibility of the full loan amount, which is useful for tax purposes. Redraw allows you to access extra repayments you've made, but some lenders restrict redraw on investment loans or charge fees for each withdrawal.
