- Jul 13
- 5 min read
Interest only home loans are back in focus for South Sydney property buyers in 2026, offering lower monthly payments during the interest-only period but requiring careful planning for the long term.
Whether you're an investor buying a unit in Zetland or Waterloo, or upgrading to a terrace in Newtown while keeping your current home as an investment, interest only loans can provide short-term cash flow relief while you build equity or restructure your finances.
My Finance Agent helps property buyers and investors across South Sydney compare interest only options from more than 60 lenders, from the major banks to specialist investment lenders.
This guide covers how interest only loans work, who qualifies, and what South Sydney borrowers should consider before choosing this loan structure.
What are interest only home loans?
Interest only home loans let you pay just the interest portion of your loan for a set period, typically one to five years, without reducing the principal balance. After the interest-only period ends, the loan reverts to principal-and-interest payments for the remaining term.
During the interest-only period, your monthly payments are significantly lower because you're not paying down the loan balance. However, at the end of the interest-only term, your payments increase substantially as you begin repaying both interest and principal over the shorter remaining loan term.
Who uses interest only loans in South Sydney?
Interest only loans suit specific situations rather than general home buying. The most common users include property investors seeking better cash flow and homeowners managing temporary financial transitions.
Property investors: Lower payments during the interest-only period can improve rental yield, especially in areas like Kingsford and Kensington near UNSW where rental demand is strong
Upgraders keeping their current home: Borrowers buying a new home while transitioning their previous property to an investment can use interest only to manage dual loan payments
Self-employed borrowers with variable income: Interest only can provide breathing room during slower business periods before converting to principal and interest
Professionals expecting income growth: Doctors, lawyers or other professionals anticipating significant salary increases may use interest only temporarily
How do lenders assess interest only applications?
Lenders apply stricter criteria for interest only loans compared to standard principal-and-interest lending. They want to see strong servicing capacity and a clear repayment strategy for when the interest-only period ends.
Investment loans
For investment loans, lenders typically allow interest only more readily, especially when rental income supports the loan servicing. They'll assess the property's rental potential and your ability to handle the higher payments when the loan converts to principal and interest.
Owner-occupied loans
Interest only on owner-occupied properties faces tighter assessment. Lenders require genuine reasons for the interest-only structure and evidence you can afford the eventual principal-and-interest payments without financial stress.

What are the benefits and risks?
Interest only loans offer clear cash flow advantages during the initial period but come with important long-term considerations that South Sydney borrowers need to understand fully.
Lower initial payments: Monthly payments can be 30-40% lower during the interest-only period, improving cash flow for investors or providing temporary relief for homeowners
Tax benefits for investors: Interest payments on investment loans are tax-deductible, while principal repayments are not
Flexibility for transitions: Useful when managing multiple properties or expecting significant income changes
Payment shock risk: When the loan converts to principal and interest, payments increase substantially and permanently
No equity building: During the interest-only period, you're not building equity through loan repayments, only through property value growth
Higher total interest: Paying interest only for longer means higher total interest costs over the loan's life
Which lenders offer interest only in South Sydney?
Most major banks and many specialist lenders offer interest only loans, but their criteria, interest-only periods and interest rates vary significantly. Some focus heavily on investment lending, while others are more restrictive.
The big four banks generally offer interest only but with conservative lending policies, particularly for owner-occupied loans. Non-bank lenders often provide more flexible options for complex situations, including borrowers with multiple investment properties across suburbs like Redfern, Mascot and Randwick.
How to apply for an interest only loan in South Sydney
Step 1: Talk to us first
Interest only loans require careful structuring and lender selection. We'll assess whether this loan type suits your situation and which lenders are most likely to approve your application based on your specific circumstances.
Step 2: Prepare your documentation
Gather income verification, asset statements, and a clear explanation of why you need interest only payments. For investment loans, include rental estimates or lease agreements.
Step 3: Choose your interest-only period
Most lenders offer interest only periods from one to five years. Your choice affects both the monthly payment relief and the eventual payment increase when converting to principal and interest.
Step 4: Plan for the conversion
Before applying, model what your payments will be when the loan converts to principal and interest. This higher payment becomes your permanent payment for the remaining loan term.
Step 5: Submit and settle
Once approved, settlement follows the standard process. Your loan starts with interest-only payments immediately, and your lender will notify you before the conversion date approaches.

Frequently Asked Questions
Can first home buyers get interest only loans?
Interest only loans are rarely suitable for first home buyers, as they don't build equity and create higher long-term costs. Most first home buyer schemes also require principal-and-interest repayments from the start.
Do interest only loans have higher interest rates?
Interest only loans typically carry slightly higher interest rates than standard principal-and-interest loans, usually 0.1% to 0.3% higher, depending on the lender and loan purpose.
What happens if I can't afford the payments when the interest only period ends?
You have several options including refinancing to extend the interest only period with another lender, switching to principal and interest over a longer term, or selling the property. Planning ahead is crucial.
Are interest only loans harder to get approved?
Yes, lenders apply stricter criteria including higher deposit requirements, stronger income verification, and clearer justification for needing interest only payments. Investment loans generally have easier approval than owner-occupied interest only loans.
Can I make principal payments during the interest only period?
Most interest only loans allow voluntary principal repayments during the interest only period, giving you flexibility to pay down the loan when your cash flow allows without the obligation of higher monthly payments.
Is it harder to get an interest only loan for a South Sydney apartment?
Some lenders apply additional restrictions in high-density unit postcodes common across parts of Zetland, Waterloo and Rosebery, but specialist lenders often provide more flexibility for apartment investment loans.
Your Next Steps
