15 May 2026 Interest Only Loans for Investors in South East Melbourne: 2026 Guide

In 2026, interest only investment loans remain one of the most powerful cash flow tools available to South East Melbourne property investors. Whether you’re buying your first investment property or building a portfolio across suburbs like Glen Iris – Malvern East or Bentleigh, the right interest only structure can improve your holding power significantly while maximising tax deductions.

Interest only periods typically run for 1-5 years, during which you pay only the interest portion of the loan – not the principal. For investors, this means higher rental yields, improved cash flow, and maximum tax deductibility on every dollar of interest paid.

EverLend helps property investors across South East Melbourne compare interest only options across 60+ lenders, completely free of charge.

Here’s what you need to know about interest only investment loans before approaching a lender.

What are interest only loans and how do they work for investors?

Interest only loans let you pay only the interest portion of your mortgage for a set period – typically 1 to 5 years – after which the loan converts to principal and interest repayments. For investment properties, every dollar of interest is tax deductible, making interest only loans particularly attractive for investors seeking to maximise their deductions while improving cash flow. The exact structure and terms depend on your lender choice, equity position, and overall investment strategy.

Investment loan options available to South East Melbourne investors

• Interest only investment loans: pay interest only for 1-5 years, then revert to principal and interest. Maximum tax deductibility during the IO period.
• Principal and interest from day one: build equity immediately but with higher repayments and lower tax deductions compared to interest only.
• Line of credit facilities: access equity as needed, pay interest only on the amount drawn. Flexibility for portfolio investors.
• Construction-to-investment loans: interest only during the build phase, then convert to standard investment loan terms upon completion.
• SMSF investment loans: limited recourse borrowing arrangements for self-managed super funds. Typically 70-80% LVR maximum.

Common mistakes investors make with interest only loans

The biggest mistake property investors make is assuming all lenders offer the same interest only terms and conditions. Some major banks have tightened their interest only policies since 2017, while specialist lenders and smaller institutions often provide more flexible arrangements. Going to your home loan bank first means missing out on potentially better terms elsewhere.

Another common error is not planning for the end of the interest only period. When your loan reverts to principal and interest repayments after 2-5 years, your monthly payments increase significantly. Smart investors either refinance to extend the interest only period with a new lender, or ensure their rental income and cash flow can handle the higher repayments. This planning should happen at the start, not when the period expires.

Interest only loan considerations for different investor types

• First-time investors: start with shorter interest only periods (2-3 years) to test your cash flow management and rental market understanding before committing to longer terms.
• Portfolio builders: maximise interest only periods (up to 5 years where available) to free up cash flow for additional property deposits and expansion.
• Renovation investors: use interest only during the renovation period when the property may be vacant, then reassess once rental income is established.
• High-income investors: maximise tax deductions through longer interest only periods, especially in years with higher taxable income from other sources.
• Pre-retirement investors: consider shorter interest only periods to begin building equity before retirement reduces your income and borrowing capacity.

Frequently Asked Questions

What is the maximum interest only period available for investment loans?

Most lenders offer interest only periods of 1-5 years for investment properties, with some specialist lenders extending this further. The exact term depends on your lender choice, loan size, and serviceability assessment.

Are interest only investment loan rates higher than principal and interest rates?

Yes – interest only investment loans typically carry a rate premium of 0.20% to 0.60% p.a. above standard principal and interest investment rates. As of April 2026, competitive interest only investment rates start from approximately 5.60% p.a. compared to 5.38% p.a. for principal and interest.

Can I extend my interest only period when it expires?

Yes, but it requires either refinancing to a new lender or reapplying with your existing lender. Most investors refinance to access better rates and terms when their initial interest only period ends.

What deposit do I need for an interest only investment loan?

Most lenders require a minimum 20% deposit for interest only investment loans, meaning 80% LVR maximum. Some specialist lenders offer 90% LVR with LMI, but interest only options become more limited at higher borrowing levels.

How does negative gearing work with interest only loans?

Interest only loans maximise your negative gearing benefits because every dollar of interest is tax deductible, and you’re not paying down non-deductible principal. This typically results in higher tax deductions compared to principal and interest loans.

Should I use a mortgage broker or go direct to a bank for an interest only investment loan?

A mortgage broker, every time. Interest only policies vary dramatically between lenders – some banks have tightened their criteria significantly since 2017, while others remain competitive. A broker comparison identifies which lenders offer the best terms for your specific investment strategy.

What happens to my repayments when the interest only period ends?

Your repayments increase significantly as you begin paying both principal and interest over the remaining loan term. For example, a $600,000 loan at 5.60% p.a. would jump from approximately $2,800 per month (interest only) to around $4,100 per month (principal and interest over 25 years).

Your Next Steps

Getting your interest only investment loan structure right affects your cash flow, tax position, and portfolio growth potential for years to come. The difference between a lender offering 2 years versus 5 years interest only, or a rate difference of 0.30% p.a., can shift your investment returns significantly across South East Melbourne’s competitive property market.
