Understanding What Lenders Review in Your Investment Loan Application
Lenders assess your investment loan application differently to a standard home loan. They evaluate your capacity to service the loan under rental income scenarios, your existing debt commitments, and the investment property's income potential. The application process requires documentation of both your financial position and the property's ability to generate returns.
In our experience working with investors throughout Prahran and the broader Stonnington area, the difference between a quick approval and a delayed application often comes down to preparation. Lenders want evidence that you understand the investment, not just the property.
Rental Income Assessment and Serviceability Calculations
Most lenders only recognise 70% to 80% of the expected rental income when calculating your borrowing capacity. This accounts for vacancy periods, maintenance costs, and income volatility. If a property in Prahran generates rental income of $650 per week, the lender might only use $455 to $520 per week in their serviceability assessment.
This calculation has a direct impact on how much you can borrow. Consider a scenario where an investor purchases a two-bedroom apartment near Chapel Street with projected rental income of $2,800 per month. The lender applies an 80% shading factor, meaning they assess serviceability based on $2,240 per month. Combined with existing commitments such as a primary residence mortgage, personal loans, or credit card limits, this shaded income figure determines the final loan amount approved. If the numbers fall short, the investor either needs to increase their deposit, reduce other debts, or consider a lower-priced property.
When structuring investment property loans, we work through these calculations before lodging an application. Knowing where you sit in advance avoids surprises later.
Documentation Requirements for Property Investor Loans
Your application needs to demonstrate both personal financial stability and the property's investment viability. Lenders typically require recent payslips or tax returns, bank statements showing genuine savings or deposit funds, and details of existing liabilities including credit cards, personal loans, and other mortgages. For the investment property itself, expect to provide a rental appraisal from a licensed property manager, a contract of sale, and evidence of any deposit paid.
Self-employed investors face additional scrutiny. Lenders usually request two years of tax returns and often two years of financial statements prepared by an accountant. If your income fluctuates or you've recently changed business structure, this can complicate the assessment. In those situations, self-employed loans may require alternative documentation or a different lender approach altogether.

How Deposit Size and LVR Affect Your Investment Loan Options
The deposit you contribute directly affects the interest rate you receive and whether you'll pay Lenders Mortgage Insurance. Most lenders offer their most competitive investor interest rates at 80% loan to value ratio or lower, meaning you need at least a 20% deposit plus costs. Borrowing above 80% LVR typically attracts LMI, which can add thousands to your upfront costs, and a higher interest rate.
If you're considering equity release from your existing home in Prahran to fund the deposit on an investment property, lenders assess this differently to cash savings. The equity is treated as genuine funds, but your total borrowing across both properties must still meet serviceability requirements. For investors with limited cash but significant equity, this can unlock opportunities that wouldn't otherwise be viable.
Interest Only Versus Principal and Interest for Investment Loans
Most property investors choose interest only repayments for the initial loan period, typically five years. This keeps monthly costs lower and maximises cash flow, which can be redirected toward paying down non-deductible debt such as your home loan or building a deposit for the next investment.
Under current lending rules, interest only investment loans are readily available, but lenders assess your capacity to repay on a principal and interest basis even if you select interest only. This means your borrowing capacity is calculated as though you were making principal and interest repayments from day one. The benefit of interest only is felt in cash flow, not in how much you can borrow.
When weighing up your investment loan options, consider how long you plan to hold the property and whether cash flow or debt reduction is your priority. Both approaches have merit depending on your broader property investment strategy.
Variable Rate or Fixed Rate Investment Loans
Variable rate investment loans give you flexibility to make extra repayments, redraw funds, and refinance without break costs. Fixed rate options lock in your repayments for a set period, which can provide certainty but limits flexibility. Many investors split their loan between variable and fixed to balance both needs.
Investor interest rates are typically higher than owner-occupier rates, but this gap varies by lender. Some lenders price investor loans only marginally above owner-occupier rates, while others apply a significant premium. Shopping across the market often uncovers better pricing than staying with your existing lender, particularly if your loan to value ratio has improved since you first borrowed.
Tax Deductions and Claimable Expenses on Investment Loans
Interest on an investment loan is generally tax deductible, provided the loan is used to purchase an income-producing property. Other claimable expenses include property management fees, council rates, insurance, repairs, and depreciation on the building and fixtures. These deductions reduce your taxable income and improve the after-tax return on your investment.
Recent changes to negative gearing announced in the Federal Budget affect properties purchased after May 12. For established residential properties acquired from that date, losses can only be offset against rental income or residential property capital gains from July 1 next year, not against wage income. Investors who purchased before that date retain the existing arrangements. New builds remain exempt from the changes and continue to allow full deductibility.
If you're planning to expand your property portfolio, understanding these rules is essential. The timing of your purchase and the type of property you select now carry different tax implications.
Refinancing Investment Loans to Access Equity or Reduce Rates
Once your investment property increases in value or you pay down the loan, you can refinance to access equity for your next purchase or to secure a lower interest rate. Lenders reassess your serviceability at the time of refinancing, so even if your property has grown in value, you still need to demonstrate you can afford the higher loan amount.
Investment loan refinance can also be used to restructure your debts, consolidate multiple properties under one lender for portfolio discounting, or switch from interest only to principal and interest if your circumstances have changed. Refinancing every few years is common among active investors who want to maintain competitive pricing and access product features that weren't available when they first borrowed.

Frequently Asked Questions
How much rental income do lenders use when assessing my investment loan application?
Lenders typically use 70% to 80% of the expected rental income in their serviceability calculations. This shading accounts for vacancy periods, maintenance costs, and income fluctuations, so a property generating $650 per week might only contribute $455 to $520 in the lender's assessment.
What deposit do I need for an investment loan?
Most lenders offer their most competitive investor interest rates with a deposit of at least 20%, which equates to an 80% loan to value ratio. Borrowing above this level typically requires Lenders Mortgage Insurance and often attracts a higher interest rate.
Can I claim interest on my investment loan as a tax deduction?
Yes, interest on an investment loan is generally tax deductible if the loan is used to purchase an income-producing property. However, recent changes to negative gearing affect how losses are offset for established residential properties purchased after May 12, with new rules taking effect from July 1 next year.
Should I choose interest only or principal and interest repayments for my investment property?
Most investors select interest only repayments to maximise cash flow and redirect surplus funds toward non-deductible debt or the next deposit. Lenders still assess your capacity based on principal and interest repayments, so the choice affects cash flow rather than borrowing capacity.
What documentation do I need to apply for an investment loan?
You'll need proof of income such as payslips or tax returns, bank statements showing deposit funds, details of existing liabilities, and property-specific documents including a rental appraisal and contract of sale. Self-employed investors typically require two years of tax returns and financial statements.
