Unlock the Secrets to Investment Loans for South Melbourne Units

Buying an investment unit in South Melbourne opens the door to one of Melbourne's most established inner-city rental markets.

The suburb sits within walking distance of the CBD, the entertainment precinct of Clarendon Street, and the parklands of Albert Park Lake. Demand from young professionals and downsizers remains consistent, and vacancy rates in the area are typically lower than outer suburbs. A well-chosen unit in South Melbourne can deliver both rental yield and long-term capital growth, but the loan structure you choose plays a significant role in how the numbers work from day one.

How Investment Loans Differ from Owner-Occupier Home Loans

Investment loans are priced differently and assessed under stricter serviceability rules than owner-occupier loans. Lenders apply a higher interest rate to investor borrowing, and APRA requires all banks to assess your ability to repay at least 3.0 percentage points above the actual loan rate. From February 2026, debt-to-income limits also apply, meaning no more than 20 per cent of new investor lending at each bank can go to borrowers with a total debt level of six times their gross income or more.

These settings mean a buyer with steady income and modest existing debt will generally find approval straightforward, while someone already carrying significant personal or investment debt may need to adjust their borrowing or wait until other commitments are reduced. Working with a mortgage broker in South Melbourne gives you access to the full panel of lenders and the ability to structure your application in a way that maximises your borrowing capacity without triggering unnecessary assessment friction.

Interest Only or Principal and Interest Repayments

Most investors choose interest-only repayments for the first five years to keep cash flow manageable and maximise their tax deductions. Under this structure, you pay only the interest portion of the loan each month, and the principal balance remains unchanged. At the end of the interest-only period, the loan typically reverts to principal and interest, and your repayments increase.

Interest-only loans attract a higher risk weighting under APRA's capital rules, which means lenders price them slightly above principal and interest loans. However, the monthly saving is usually enough to justify the difference, particularly if the property is negatively geared and you are using the tax benefits to build equity elsewhere.

If your rental income is strong and your goal is to pay down debt more quickly, a principal and interest structure from the outset may suit you. In our experience, most South Melbourne unit buyers who are adding to an existing portfolio prefer to preserve cash flow and opt for interest only, while first-time investors sometimes choose principal and interest for the reassurance of seeing the balance reduce each month.

Variable or Fixed Rate Investment Loans

Variable rates give you full flexibility to make extra repayments, redraw funds, and refinance without penalty. Fixed rates lock in your repayment amount for a set period, usually one to five years, but come with restrictions on additional repayments and early exit costs if you sell or refinance before the fixed term ends.

At current variable rates, an investor with a unit valued near the South Melbourne median and borrowing at 80 per cent LVR would pay a rate that reflects both the lender's assessment of investment risk and the prevailing cash rate settings from the Reserve Bank. Fixed rates provide certainty during periods of rate volatility, but if rates fall or your circumstances change, you may find yourself locked into a loan that no longer suits your strategy.

A split loan, where part of your borrowing is fixed and part remains variable, can offer a middle path. Consider a buyer who borrows $500,000 to purchase a two-bedroom unit near Clarendon Street. They fix $300,000 for three years to lock in certainty on the bulk of their repayments, and leave $200,000 on a variable rate with an offset account attached. Rental income sits in the offset, reducing interest on the variable portion, while the fixed portion provides a known monthly cost for budgeting. At the end of the fixed term, they can reassess and refinance the entire loan if needed.

Loan to Value Ratio and Deposit Requirements

Most lenders will lend up to 90 per cent of the purchase price for an investment property, provided you meet their serviceability criteria and pay for Lenders Mortgage Insurance. LMI premiums are calculated on a sliding scale and become significantly more expensive above 80 per cent LVR. For a unit purchase, an 80 per cent LVR loan avoids LMI entirely and keeps your borrowing costs lower.

If you are buying your first investment property and do not have sufficient cash savings for a 20 per cent deposit, you may be able to use equity release from your existing home. Lenders will allow you to borrow against the equity in your owner-occupied property to fund the deposit and purchase costs for the investment unit, provided your total borrowing across both properties remains within serviceability limits.

Units in South Melbourne typically have body corporate fees that range from moderate to high depending on the age and facilities of the building. Lenders factor these fees into their serviceability calculations, so a property with quarterly body corporate levies above $2,000 will reduce your borrowing capacity compared to a similar unit with lower fees.

Rental Income and Serviceability

Lenders assess rental income at a discounted rate, usually 80 per cent of the market rent, to account for vacancy periods and maintenance costs. If you are purchasing a unit that is already tenanted, the lender will use the current lease agreement as evidence of income. If the property is vacant at settlement, you will need to provide a rental appraisal from a licensed property manager.

South Melbourne's proximity to the CBD and major employment hubs means rental demand remains strong, but lenders will still apply a haircut to the income when calculating your ability to service the loan. A unit generating $600 per week in rent will be assessed as though it earns $480 per week, and you will need to demonstrate that your salary and any other income can cover the gap between rental income and loan repayments, plus your existing living expenses and commitments.

For buyers expanding your property portfolio, this calculation becomes more complex. Each additional property adds both income and debt to your serviceability profile, and lenders will look at the net position across your entire portfolio when deciding how much they are willing to lend.

Tax Deductions and Negative Gearing

Interest on an investment loan is fully deductible against your rental income, along with body corporate fees, 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, including salary, reducing your overall tax liability.

For properties acquired after 12 May 2026, negative gearing rules changed. Losses on established investment properties purchased after that date can only be offset against income from other residential properties, not against salary or wages. However, properties held at that date, properties under contract at that date, and new builds purchased after that date remain fully deductible under the previous rules.

Most units in South Melbourne are established properties, so if you are purchasing now, you will be subject to the new rules from the 2027-28 income year onward. Losses will still be deductible, but only against future income from this property or other residential investments. You can carry forward unused losses indefinitely, which means the deduction is deferred rather than lost. This changes the cash flow profile of the investment but does not eliminate the tax benefit entirely.

Loan Features That Support Long-Term Portfolio Growth

An offset account linked to your investment loan allows you to park surplus cash and reduce the interest charged on your loan without making a formal repayment. Because investment loan interest is tax deductible, many investors prefer to keep their offset account linked to their owner-occupied loan and make interest-only payments on the investment loan to maximise deductions. However, if you are building cash reserves for your next purchase, an offset account on the investment loan keeps those funds accessible while reducing your interest cost in the meantime.

Redraw facilities allow you to access any extra repayments you have made above the minimum required. This can be useful if you need to fund property maintenance or settlement costs on a future purchase, but be aware that lenders sometimes restrict redraw access on investment loans, and any redrawn funds may not be deductible unless they are used for investment purposes.

Some lenders also offer rate discounts for professional packages or for borrowers who consolidate multiple loans with the same institution. If you are planning to build a portfolio of several properties, it is worth considering whether your lender offers any pricing incentive for portfolio growth or whether you would be served by spreading your loans across multiple lenders to maintain flexibility and access to competitive pricing at each refinance.

Refinancing Your Investment Loan

Refinancing becomes relevant when your current loan no longer offers a competitive rate, when you want to access equity for another purchase, or when your lender's servicing policy has tightened and you need to move to a more accommodating institution. Most investors review their investment loan options every two to three years, particularly when fixed terms expire or when portfolio growth requires a restructure.

If you have owned your South Melbourne unit for several years and the property has increased in value, refinancing allows you to access that equity without selling. The equity can then be used as a deposit for another investment property, allowing you to grow your portfolio while keeping your original asset. Lenders will assess the refinance as a new application, so you will need to meet current serviceability and DTI requirements, but the process is usually faster than a purchase application because the property is already owned and valued.
