Investment Loan Approval: Everything You Need to Know

Getting an investment loan approved isn't the same as getting a home loan approved.

Lenders apply stricter serviceability tests, factor in rental income differently, and assess your application against macroprudential limits that don't exist for owner-occupiers. If you're buying in Liverpool or the surrounding south-west corridor, understanding how lenders calculate your borrowing capacity, and what's changed since early 2026, will shape whether your application gets approved and how much you can borrow.

How Lenders Calculate Borrowing Capacity for Investment Property

Lenders assess your ability to repay an investment loan at an interest rate that sits 3.0 percentage points above the actual loan rate. If you're quoted a variable rate around 6.2 per cent, the lender will assess your income and expenses as if you're paying 9.2 per cent. This serviceability buffer has been in place since October 2021 and applies to every new borrower, investor or owner-occupier.

Rental income is included in the serviceability calculation, but lenders don't count the full amount. Most lenders apply a shading rate, which means they'll assess between 70 and 80 per cent of the expected rent to account for vacancy periods, maintenance costs, and property management fees. Some will shade more conservatively if the property type carries higher perceived risk, such as studio apartments or properties in areas with above-average vacancy rates.

Consider a buyer purchasing a two-bedroom unit near Liverpool Station with an expected rental return of $550 per week. The lender assesses serviceability using $440 per week, not the full $550. That difference reduces how much you can borrow by tens of thousands of dollars, depending on your other income and commitments.

Debt-to-Income Limits That Apply from February 2026

From 1 February 2026, lenders can only approve up to 20 per cent of new investor loans to borrowers whose total debt sits at six times their gross annual income or higher. This limit applies separately to each lender's investor loan portfolio and is measured quarterly.

If your total household income is $120,000 per year and your total borrowing across all loans, including the new investment loan, would exceed $720,000, you fall into the high debt-to-income category. The lender can still approve your application, but you're competing for a place within that 20 per cent allocation. If the lender has already written a high volume of investor loans above six times income that quarter, your application may be declined or deferred, even if you meet all other criteria.

This limit doesn't apply to non-bank lenders, but it does apply to every bank, credit union and building society regulated by APRA. Borrowers who were already approved or settled before 1 February 2026 are not affected, and the limit doesn't apply retrospectively to existing loans.

Interest-Only Periods and How They Affect Approval

Many investors choose interest-only repayments to maximise cash flow and tax deductions in the early years of ownership. Lenders will generally offer interest-only periods of up to five years on standard investment loans, after which the loan reverts to principal and interest repayments.

Serviceability is still assessed on a principal and interest basis, even if you elect to pay interest-only. The lender calculates repayments as if you're paying down the loan from day one, then applies the 3.0 percentage point buffer on top. That means your income needs to support the higher repayment structure, regardless of what you actually pay each month during the interest-only period.

Longer interest-only periods, beyond five years, may be available but typically require the loan to sit below 80 per cent LVR. If the LVR is above 80 per cent and the interest-only term exceeds five years or is unspecified, the loan is classified as non-standard under APS 112, which increases the lender's capital cost and generally makes the loan harder to approve or more expensive to write.

Deposit Requirements and Lenders Mortgage Insurance

Most lenders require a minimum 10 per cent genuine savings deposit for an investment property purchase, though some will accept 5 per cent in specific circumstances, particularly if you're refinancing equity from an existing property. If your deposit is less than 20 per cent of the property value, you'll need to pay Lenders Mortgage Insurance.

LMI is a one-off premium that protects the lender if you default, and the cost increases sharply as the LVR rises. A loan at 90 per cent LVR will carry a significantly higher LMI premium than one at 85 per cent. The premium can be capitalised into the loan amount, but doing so increases your total borrowing and reduces your cash flow.

If you already own property in Liverpool or elsewhere in the south-west, you may be able to use equity release from that property to fund the deposit on your next purchase, avoiding the need to save additional cash. Lenders will assess the combined LVR across your portfolio and apply serviceability tests to the total debt, but this approach is commonly used by investors building a portfolio.

How Rental Income Is Assessed Across Different Property Types

Lenders assess rental income differently depending on the property type, location, and lease status. If the property is already tenanted and you can provide a signed lease agreement, most lenders will use the contracted rent, shaded by 20 to 30 per cent, in their serviceability calculation. If the property is vacant or you're buying off-the-plan, the lender will rely on a rental assessment or valuation, and the shading may be more conservative.

In Liverpool, where the median unit rent has remained relatively stable and vacancy rates sit close to the regional average, lenders generally accept standard shading. Properties further out, or in areas with higher vacancy or lower demand, may attract heavier discounting, which reduces how much you can borrow.

Units in strata schemes with commercial ground-floor tenancies, or buildings with mixed residential and commercial use, are sometimes assessed more conservatively. Some lenders will apply a higher shading rate or request additional documentation, particularly if body corporate fees are high or if there's a history of special levies.

Tax Changes That Affect Investment Loan Approval from 2027

From the 2027-28 income year, losses from established residential investment properties purchased after 12 May 2026 can only be offset against income from other residential properties, not against salary or wages. If you bought before that date, or if you're purchasing a qualifying new build, negative gearing against all income remains available.

Lenders don't directly assess your tax position when approving a loan, but the change affects post-tax cash flow, particularly for investors relying on negative gearing to support repayments from salary income. If you're considering multiple purchases, the order and timing of those purchases will determine which properties benefit from full negative gearing and which are subject to the new quarantining rules.

Capital gains tax treatment also changes from 1 July 2027. For gains accruing after that date, the 50 per cent discount is replaced with cost base indexation and a 30 per cent minimum tax rate on real gains. Eligible new builds retain access to both the old discount and the new indexed treatment as a choice at sale. This doesn't affect loan approval directly, but it changes the long-term economics of holding versus selling, particularly for investors planning to build wealth through portfolio growth and eventual disposal.

What Lenders Look for in Your Application

Every lender has slightly different credit policies, but all assess the same core factors when deciding whether to approve an investment loan application. They review your income stability, existing debts, credit history, deposit source, and the property itself.

If you're self-employed, most lenders require two years of tax returns and financials. If you're a PAYG employee, recent payslips and a letter of employment are usually sufficient. Lenders will also review your spending patterns through bank statements, looking for regular expenses, existing loan commitments, and any signs of financial stress such as dishonours, overdrawn accounts, or reliance on short-term credit.

The property is assessed independently through a valuation ordered by the lender. If the valuation comes in below the purchase price, the lender will use the lower figure to calculate the LVR, which may mean you need a larger deposit or are required to pay LMI when you weren't expecting to. In areas like Liverpool, where development is active and off-the-plan settlements are common, valuation risk is something to plan for, particularly if you're buying in a new release precinct with limited comparable sales.

How to Position Your Application for Approval

Lenders want to see that you understand the commitment you're taking on and that you've planned for vacancy, maintenance, and rate rises. If you're applying for borrowing capacity that sits close to the debt-to-income threshold or the upper limit of your serviceability, the lender will scrutinise your application more closely.

Reducing discretionary spending in the months before you apply, paying down credit card limits, and consolidating smaller debts can all improve your serviceability position. Even if you don't use a credit card, the lender will assess serviceability as if you're using the full limit every month, so closing unused accounts or reducing limits makes a material difference.

If you've had credit issues in the past, such as defaults, missed payments, or a history of dishonours, some lenders will decline your application automatically. Others, particularly non-bank lenders, have more flexible credit policies and may still approve your loan if the issues are explained and resolved. Working with a mortgage broker in Liverpool who understands which lenders assess credit history more pragmatically will save you time and avoid multiple declined applications, which themselves can affect your credit file.
