Buying an established investment property in Malvern means competing in a market where median house prices consistently sit well above the Melbourne average and rental yields are modest compared to outer suburbs.
The right loan structure can make the difference between a property that drains cash flow and one that positions you for long-term growth. Most investors in this suburb are drawn to capital appreciation rather than immediate rental return, which makes the way you structure your borrowing particularly important.
What Deposit Do You Need for an Investment Property Loan?
Most lenders require a minimum 10 per cent deposit for an investment loan, though you will pay Lenders Mortgage Insurance if your deposit is below 20 per cent. LMI is calculated on a sliding scale based on your loan amount and the loan-to-value ratio, and it can add several thousand dollars to your upfront costs.
If you are using equity from your Malvern home to fund the deposit, the lender will assess the combined borrowing against both properties. In a scenario where you hold $400,000 in usable equity and want to purchase a unit near Glenferrie Road, the lender will calculate your borrowing capacity based on rental income from the new property, your existing home loan commitments, and your personal income. They will also apply a serviceability buffer of at least 3.0 percentage points above the loan product rate, meaning your income needs to cover repayments at a rate higher than what you will actually pay.
Deposit size also affects your interest rate. Lenders typically offer better pricing to borrowers who can put down 20 per cent or more, because the loan carries less risk.
How Lenders Assess Rental Income on Investment Loans
Lenders will only count a portion of the expected rental income when calculating your borrowing capacity. Most use 80 per cent of the rental figure to account for vacancy periods, maintenance costs, and other holding expenses.
Consider a two-bedroom apartment in central Malvern that rents for $650 per week. The lender will assess your income as $520 per week, or roughly $27,000 per year, before factoring in your existing debts and living expenses. If the property is still tenanted at the time of purchase, the lender may request a copy of the lease agreement to verify the rental amount.

Some lenders will accept a rental appraisal from a licensed property manager instead, particularly if the property is being sold vacant. The appraisal should reflect current market conditions in Malvern rather than optimistic projections, because lenders will cross-check the figure against comparable properties in the area.
Interest Only or Principal and Interest Repayments?
Interest only repayments are common for investors because they reduce the monthly cash outflow and leave more capital available for other investments or to cover holding costs. Most lenders offer interest only periods of up to five years on investment loans, after which the loan reverts to principal and interest unless you apply to extend.
The trade-off is that you are not reducing the debt. If property values in Malvern remain flat or grow more slowly than expected, you will not be building equity through repayments. You will still benefit from any capital growth, but the loan balance stays the same throughout the interest only period.
Principal and interest repayments cost more each month, but they reduce your loan balance over time and can make it simpler to access equity later if you want to expand your portfolio. Some investors start with interest only and switch to principal and interest once their income increases or they have acquired additional properties.
Fixed or Variable Rate for Investment Borrowing?
A variable rate gives you flexibility to make extra repayments or refinance without penalty, and you benefit immediately if rates fall. Most variable rate investment loans also come with features like offset accounts and redraw facilities, which can help manage cash flow.
A fixed rate locks in your repayments for a set period, usually between one and five years. If you are holding a property in Malvern long term and want certainty around your cash flow, a fixed rate can make budgeting simpler. The downside is that you may pay break costs if you sell the property or refinance before the fixed period ends, and most fixed rate products do not allow extra repayments beyond a small annual cap.
Some investors split their loan between fixed and variable portions to combine rate certainty with repayment flexibility.
Tax Deductions and Negative Gearing Rules
Interest on your investment loan is deductible against rental income, along with other holding costs like council rates, insurance, property management fees, and depreciation. If your deductible expenses exceed your rental income, the property is negatively geared, and you can offset the loss against your other income.
From the 2027-28 income year, losses on established investment properties purchased after 12 May 2026 can only be deducted against income from other residential properties, not against salary or wages. Losses can be carried forward to future years. Properties purchased before that date, or properties under contract before that date, are not affected and can continue to be negatively geared against all income. New builds remain fully deductible regardless of when they are purchased.
If you are purchasing an established property in Malvern now, the new rules will apply to your loan interest and other deductible costs from 1 July 2027 onward. You should factor this into your cash flow projections, particularly if you were relying on negative gearing to reduce your taxable income.
Loan Features That Suit Property Investors
An offset account linked to your investment loan can reduce the interest you pay without affecting the deductibility of the loan. If you hold surplus cash in the offset, the interest is calculated on the net balance, but the full loan amount remains deductible because you have not made a repayment.
Some lenders offer rate discounts if you hold multiple loans or investment properties with them, or if you also have your owner-occupied home loan with the same institution. The discount is typically small, between 0.10 and 0.25 percentage points, but it can add up over the life of the loan.
Redraw facilities allow you to access any extra repayments you have made, which can be useful if you need funds for repairs or other expenses. Not all lenders offer redraw on interest only loans, so check before you apply.
Borrowing Limits and Debt-to-Income Restrictions
From 1 February 2026, lenders are restricted in how much they can lend to borrowers with a total debt-to-income ratio of six times or greater. Each lender can approve up to 20 per cent of new investor loans to borrowers above this threshold, measured quarterly.
If your total borrowing across all properties is more than six times your gross annual income, you may find it harder to secure approval, particularly if the lender has already reached its quarterly limit. Some lenders are more conservative and apply their own lower thresholds.
In our experience, Malvern buyers with multiple investment properties or large owner-occupied loans can hit this limit sooner than they expect, particularly if rental income is being shaded down to 80 per cent for serviceability purposes.
How to Compare Investment Loan Options
Rate is important, but it is not the only factor. A loan with a slightly higher rate but lower fees, better offset functionality, or more flexible repayment options can deliver better value over time.
Some lenders offer discounted rates for new borrowers but charge higher rates on existing loans, which means you may need to refinance in a few years to stay competitive. Others offer consistent pricing but fewer features. Working with a mortgage broker in Malvern gives you access to a broader range of lenders and loan products, including options not available directly to the public.
You should also consider how the lender assesses rental income, whether they allow top-ups for renovations or other capital works, and how they handle requests to switch between interest only and principal and interest.
