Variable rate investment loans give you flexibility that fixed loans cannot match. The repayment structure, offset account access, and ability to refinance without penalties all shape how effectively you can manage cashflow and build equity across multiple properties.
Bentleigh East investors often hold properties in mixed portfolios, combining local units near Centre Road with regional assets or interstate holdings. A variable rate structure allows you to adjust repayments, access redraw facilities, and leverage equity as your portfolio grows without the restrictions that come with fixed terms.
Interest Only or Principal and Interest for Investment Properties
Interest only repayments reduce monthly outgoings, which improves cashflow and can increase your borrowing capacity for additional purchases. Most lenders offer interest only periods of one to five years on investment loans, after which the loan reverts to principal and interest unless you apply for an extension.
Consider an investor who purchases a two-bedroom unit in Bentleigh East as a rental property. They arrange a five-year interest only period on a variable rate loan. Monthly repayments sit at around $1,800 instead of $2,400 on a principal and interest structure. That $600 difference allows them to hold a buffer for vacancy periods, cover body corporate fees, and service a second loan on a regional property within 18 months. After five years, they refinance and extend the interest only period on both properties, maintaining cashflow while rental income increases.
Interest only structures work when rental income and capital growth are your priorities. Principal and interest repayments build equity faster but reduce flexibility, particularly if you plan to acquire more properties within a short timeframe.
Variable Rate Features That Support Portfolio Growth
Variable rate investment loans typically include offset accounts, unlimited additional repayments, and redraw facilities. These features let you park surplus income in an offset account to reduce interest charges without locking funds away, or pay down the loan and redraw later to fund deposits on subsequent purchases.
An offset account linked to your investment loan reduces the balance on which interest is calculated. If you hold $30,000 in offset and owe $500,000, you pay interest on $470,000. Rental income, tax refunds, and any surplus income can sit in offset and reduce interest costs immediately, while remaining accessible if a maintenance issue or vacancy arises.
Redraw facilities let you access any additional repayments made above the minimum. This differs from an offset account because the funds are held within the loan itself rather than a separate account. Both serve similar purposes, but offset accounts provide cleaner separation for tax record keeping, which matters when claiming deductions.

How Loan to Value Ratio Affects Variable Rate Pricing
Lenders price investment loans based on risk, and your loan to value ratio directly influences the interest rate you receive. Borrowing above 80% typically requires Lenders Mortgage Insurance and attracts a higher rate. Staying at or below 80% LVR gives you access to better pricing and avoids LMI altogether.
In Bentleigh East, where median unit values sit within reach of first-time investors, a 20% deposit often means $100,000 to $120,000 in equity or cash. If you already own a home in the area, leveraging equity through refinancing can provide that deposit without needing to save the full amount separately. Variable rate loans on refinancing allow you to access equity, use it as a deposit, and maintain flexibility across both loans.
Rate discounts also depend on the loan amount. Lenders offer deeper discounts on larger loans, so a $600,000 investment loan may attract a rate 0.15% to 0.25% lower than a $300,000 loan, even at the same LVR. This difference compounds over time and affects both cashflow and total interest paid.
Refinancing Investment Loans Without Break Costs
Variable rate loans let you refinance without penalty, which gives you the option to move lenders if a better rate or product becomes available. Fixed rate loans charge break costs that can run into thousands of dollars if you exit early, but variable loans impose no such fees beyond standard discharge costs.
Refinancing becomes relevant when your equity position improves, your LVR drops below 80%, or you want to consolidate multiple investment loans under one lender for portfolio pricing. Some lenders offer discounts when you hold multiple investment loans with them, reducing the rate across all properties as your total borrowing increases.
In our experience, investors who review their loan structure every two to three years can identify opportunities to reduce rates, access equity, or restructure repayments in line with portfolio goals. Variable rate loans make that process straightforward because there are no fixed term constraints.
How Recent Tax Changes Affect Variable Rate Investment Loan Strategy
From 1 July 2027, negative gearing deductions on established residential properties purchased after 12 May 2026 will only offset rental income or capital gains from residential property, not wage income. This changes the cashflow calculation for some investors, particularly those relying on tax refunds to service loans.
Variable rate loans with offset accounts and flexible repayment options become more useful in this environment. If you cannot claim the full loss against your salary, holding surplus income in offset reduces your interest expense directly, which improves your net position without relying on tax deductions. Interest only repayments also allow you to minimise outgoings while rental income builds over time.
Investors who purchased before Budget night retain the existing negative gearing and capital gains arrangements, but anyone acquiring property from 13 May 2026 onwards should factor the new rules into their cashflow projections. A variable rate structure gives you the flexibility to adjust repayments, refinance, or leverage equity as your circumstances and the tax environment shift.
Choosing the Right Variable Rate Investment Loan Product
Not all variable rate investment loans offer the same features. Some lenders include offset accounts and unlimited redraws as standard, while others charge monthly fees for those features or restrict redraw access. Comparing loan products means looking beyond the advertised rate to the features that support your investment strategy.
Lenders also differ in how they assess rental income. Some apply a 75% shading factor, meaning they only count 75% of projected rent when calculating borrowing capacity. Others use 80%, which can increase the loan amount you qualify for. If you plan to grow your portfolio quickly, working with a lender that applies a higher shading factor and offers portfolio pricing can make a tangible difference to how much you can borrow across multiple properties.
TM Finance Group can help you access investment loan options from banks and lenders across Australia, comparing features, rates, and serviceability to find a product that aligns with your goals. Variable rate loans offer flexibility, but the specific terms and features vary widely between lenders, and choosing the right structure upfront saves time and cost later.

Frequently Asked Questions
Should I choose interest only or principal and interest for an investment loan?
Interest only repayments reduce monthly costs and improve cashflow, which helps if you plan to acquire additional properties. Principal and interest builds equity faster but limits flexibility, so your choice depends on whether portfolio growth or debt reduction is the priority.
What variable rate features matter most for property investors?
Offset accounts, unlimited additional repayments, and redraw facilities give you control over interest costs and access to funds. These features let you reduce interest charges, park surplus income, and access equity without refinancing.
How does loan to value ratio affect my investment loan interest rate?
Borrowing above 80% LVR attracts higher rates and requires Lenders Mortgage Insurance. Staying at or below 80% gives you access to lower rates and avoids LMI, which improves cashflow and reduces upfront costs.
Can I refinance a variable rate investment loan without penalties?
Yes, variable rate loans do not charge break costs, so you can refinance whenever a better rate or product becomes available. This flexibility lets you adjust your loan structure as your portfolio grows or market conditions change.
How do the new negative gearing rules affect variable rate investment loans?
From 1 July 2027, losses on established properties purchased after 12 May 2026 only offset rental income or property capital gains, not wage income. Variable rate features like offset accounts help reduce interest costs directly, which matters more when tax deductions are limited.
