Investment Property Loan Melbourne 2026: What Investors Need to Know Before Borrowing

Melbourne’s property market has regained momentum through 2026 — and investors are buying again. But the lending landscape for investment properties looks very different from what it did two years ago. Serviceability buffers, interest-only approval rates, lender risk appetites and the way banks assess rental income have all shifted. Getting the loan structure right from the start can mean the difference between a portfolio that grows and one that stalls at property two.

At IFG we’ve been structuring investment loans for Melbourne clients since 2003. Here’s what you actually need to know before you borrow.

How Lenders Assess Investment Borrowing Capacity

Investment lending is assessed differently from owner-occupier lending — and understanding this is the first step to a stronger application.

The biggest variable is how lenders treat rental income. Most major banks will use only 70–80% of the gross rental income to account for vacancies, management fees and repairs. So if your property earns $2,600 per month in rent, the bank may credit only $1,820–$2,080 toward your income for servicing purposes. Some lenders are more generous, which is one reason why choosing the right lender — not just any lender — matters for investors.

On top of that, every lender must apply the APRA serviceability buffer of 3% above the actual loan rate. At a 6.5% investment rate, you’re assessed at 9.5%. This is the same buffer applied to owner-occupier loans, but the combination of a higher investment rate and shaded rental income means your borrowing power is materially lower for an investment purchase than an equivalent owner-occupier one.

Existing debts — including your own home loan, car loans and credit card limits (not balances, limits) — all reduce your investment borrowing capacity. Before you start shopping for a property, run a borrowing power estimate and speak with a broker who can model your position across multiple lenders.

Interest-Only vs Principal & Interest: Which Is Right for Investors?

This is one of the most frequently asked questions we get from Melbourne investors, and the answer depends on your strategy rather than a single universal rule.

Interest-only (IO) loans keep your repayments lower during the IO period, preserving cash flow. They also mean your deductible interest expense stays higher for longer, which matters if you’re negatively geared. For investors who plan to sell within 5–7 years, or who are actively reinvesting surplus cash flow into the next acquisition, IO can be the right structure.

Principal & interest (P&I) loans attract lower interest rates — typically 0.10–0.30% cheaper than an IO equivalent with the same lender. Over a 30-year term, that adds up. If you’re holding for the long term and the property is positively geared (or close to it), P&I often makes more mathematical sense.

Feature	Interest-Only	Principal & Interest
Monthly repayments	Lower	Higher
Rate	Typically 0.10–0.30% higher	Lower
Tax-deductible interest	Maximised during IO period	Reduces over time
Debt reduction	None during IO period	Ongoing from day one
IO term available	Usually 5 years (some 10)	N/A
Best for	Short-medium hold, portfolio growth	Long-term hold, lower total cost

One important note: when your IO period ends and the loan reverts to P&I, your repayments can jump significantly because you’re now repaying a full loan over a shorter remaining term. Planning for this — or arranging a new IO term in advance — is part of good portfolio management. Speak with your accountant about which structure best suits your tax position before deciding.

Using Equity to Buy an Investment Property

If you already own a home with equity, it’s often possible to use that equity as a deposit (and potentially for purchase costs) for your investment property — without needing to save additional cash.

Most lenders will allow you to access equity up to 80% of your property’s current value (sometimes more with LMI) less your existing loan balance. For example:

• Home value: $1,000,000
• 80% of value: $800,000
• Existing loan: $550,000
• Usable equity: $250,000

That $250,000 could fund the 20% deposit on an $800,000–$900,000 investment property, plus stamp duty and purchase costs in Victoria. You’d then take a separate loan for the investment property itself, secured against that property.

The key structural question is whether to cross-collateralise (use your home as additional security for the investment loan) or keep them separate. We generally recommend keeping loans separate where possible. Cross-collateralisation gives the bank more control over your assets and can complicate future refinancing or selling one property without affecting the other. A good broker structures this cleanly from the start. See our refinancing guide if you’re looking to unlock equity from an existing loan.

What Lenders Look for in 2026

Lender appetite for investment lending has shifted considerably over the past two years. After APRA’s tightening cycle, most banks now apply stricter income verification, more conservative rental shading and tighter LVR caps for investors — particularly those with multiple existing investment properties.

Key factors lenders assess in 2026:

• Total debt exposure — lenders increasingly assess your entire portfolio exposure, not just the new loan
• Rental income documentation — signed leases, rental statements and property manager letters are all expected
• Property type and location — some lenders apply higher LVR restrictions for inner-city apartments, studio apartments or high-density postcodes
• Number of investment properties held — policies vary, but several major lenders limit investor customers to 2–4 properties before requiring commercial-grade assessment
• Employment stability — PAYG borrowers are generally assessed more favourably than self-employed, though specialist lenders can accommodate both

Because lender policies differ significantly, the lender who approved your last investment loan may not be the right choice this time. A broker with access to a deliberately broad panel of bank, non-bank and specialist lenders can compare policies as well as rates.

Victorian Stamp Duty for Investment Properties

It’s important to note that the Victorian stamp duty concessions available to first home buyers do not apply to investment properties. Investment purchases are subject to the full stamp duty scale, which for a $750,000 investment property in Victoria is approximately $40,070 — a significant purchase cost to factor into your deposit and borrowing plan.

Use our Victoria stamp duty calculator to get a precise figure for your purchase price. This amount will need to be paid at settlement and is generally not lendable — it must come from your own funds or usable equity.

When Does an Investment Loan Make Sense in 2026?

With interest rates still elevated relative to the 2020–2022 era, investors need to run the numbers more carefully than they might have a few years ago. Here are some scenarios where investment borrowing makes strong sense right now:

• You have substantial equity in your home and can avoid LMI on the new purchase
• The property is neutrally or positively geared at current rates — or close to it, with clear rental growth prospects
• You have a long hold horizon (7+ years) and can absorb short-term cash flow pressure
• Your borrowing capacity is strong and adding the loan doesn’t overextend your overall position
• You’re in a high income bracket where negative gearing provides a meaningful tax offset (confirm with your accountant)

Scenarios where it may be worth pausing:

• The serviceability numbers only just work — leaving no buffer for rate rises or vacancy
• You’re relying on above-market rental growth assumptions to make the deal stack
• Your existing debt is already at high LVR and a correction would put you under water
• You haven’t stress-tested the deal at a rate 1–2% higher than today

Frequently Asked Questions

Can I use my superannuation to buy an investment property?

Through a self-managed super fund (SMSF), yes — but only for commercial property as new-residential SMSF lending is heavily restricted. The rules are complex and the loan structure is fundamentally different from a personal investment loan. See our SMSF lending page for more detail. Always speak with your financial adviser and accountant before pursuing this path.

How much deposit do I need for an investment property in Melbourne?

Most lenders require a minimum of 20% to avoid Lenders Mortgage Insurance (LMI) on an investment purchase. Some lenders will go to 90% LVR with LMI, but this adds cost and the loan becomes more expensive. A 20% deposit plus stamp duty and purchase costs is the most practical target for most Melbourne investors.

Can I get an investment loan if I’m self-employed?

Yes. Self-employed borrowers can access investment lending through standard income verification (tax returns, NOAs, business financials) or through alternative documentation lenders if your income is harder to evidence. IFG arranges investment loans for self-employed clients regularly — see our self-employed home loan page for how we approach income verification.

Will buying an investment property affect my ability to refinance my home loan?

It can. Adding an investment loan increases your total debt, which affects your serviceability position. If you’re planning to refinance your home loan in the near term, it’s worth doing that first, then adding the investment loan — rather than the other way around. We can help you sequence this correctly. Talk to us before you commit.
