A fixed rate investment loan locks your interest rate for a set period, typically one to five years, protecting you from rate increases during that time.
For Richmond property investors, this certainty matters when planning cash flow around rental income and investment property finance commitments. The challenge is that fixed rate products come with features that differ substantially from variable loans, particularly around prepayments, offset accounts, and refinancing options.
How Fixed Rate Periods Affect Your Investment Strategy
Fixed rate periods determine how long your rate remains unchanged, and this timeframe should align with your broader property investment strategy. A three-year fixed period provides stability during the initial years when rental income may be establishing, while a five-year fix suits investors who want to eliminate rate risk throughout a longer holding period.
Consider an investor who purchased a two-bedroom apartment near Bridge Road in Richmond for $750,000 with a 20% deposit. By fixing $600,000 at a specific rate for three years, they locked in repayment certainty at $3,240 per month on a principal and interest loan. This allowed them to budget confidently around their $2,600 monthly rental income, knowing exactly what the shortfall would be without worrying about rate movements. When rental income covers most of the repayment, even small rate increases can eliminate negative gearing benefits or push the property into negative cash flow territory.
The fixed period also determines when you'll face potential rate changes. When your fixed term ends, you'll either need to refix at the prevailing rate or revert to a variable rate, which means your investment loan refinance strategy needs consideration well before expiry.
Break Costs and Exit Flexibility on Fixed Rates
Break costs apply when you exit, refinance, or make repayments above the allowed limit during your fixed rate period. These costs compensate the lender for the difference between your fixed rate and current wholesale rates, and they can run into thousands of dollars depending on how much rates have moved since you fixed.
Most fixed rate investment loans allow limited additional repayments, typically $10,000 to $30,000 per year, without triggering break costs. Some lenders charge break costs on any additional repayment beyond this threshold, while others only apply them if you fully exit the loan. This becomes relevant when you want to use surplus rental income or capital gains from other properties to reduce your loan amount.
In our experience, Richmond investors who fix their rates often do so during periods of rate uncertainty but then find their circumstances change. A promotion, inheritance, or sale of another property creates surplus funds they want to apply to the loan, only to discover they face a $15,000 break cost to do so. Before committing to a fixed rate, understand not just the rate itself but the cost of changing direction if your financial position improves.

Offset Accounts and Fixed Investment Loans
Most fixed rate investment loans do not offer full offset account functionality, which affects how you manage your cash flow and maximise tax deductions. Variable rate loans commonly include 100% offset accounts where every dollar deposited reduces the interest charged, while fixed loans typically offer either no offset or a partial offset that only reduces interest on a portion of your balance.
This limitation matters for property investors because holding surplus cash in an offset account against your investment loan means that cash isn't earning taxable interest elsewhere. The interest you save is effectively tax-free income. Without a full offset on a fixed loan, you'll need to either keep surplus funds in a savings account where interest is taxable, or make additional repayments that may trigger break costs later.
Some lenders structure their fixed products with linked redraw facilities instead of offsets. While redraw allows you to access extra repayments you've made, it doesn't provide the same daily interest reduction that an offset does, and accessing redraw funds during a fixed period may still trigger break costs depending on the lender's terms.
For an investor holding $40,000 in reserve funds for property maintenance or vacancy periods, the difference between a variable loan with full offset and a fixed loan without it can cost several thousand dollars per year in foregone interest savings. You're paying interest on funds you could otherwise be offsetting.
The Split Loan Approach for Investment Properties
A split loan structure divides your borrowing between fixed and variable portions, allowing you to balance rate certainty with flexibility. A typical split might allocate 50-70% of the loan amount to a fixed rate, with the remainder on a variable rate that includes full offset and unrestricted additional repayments.
Consider a Richmond investor with an $800,000 investment property loan who splits $500,000 onto a three-year fixed rate and $300,000 onto a variable rate with offset. They gain repayment certainty on the majority of their borrowing while maintaining flexibility to deposit rental income, use surplus cash flow, or make additional repayments against the variable portion without penalty. If they need to refinance to release equity for another purchase, they only face break costs on the fixed portion, reducing the financial impact.
The split structure also helps at fixed rate expiry. When the fixed term ends, only that portion needs to be refinanced or reverted to variable, rather than the entire loan amount moving at once. This creates more opportunity to stagger rate exposure and negotiate with lenders from a position where you're not forced to accept whatever rate is offered on the full balance.
Fixed Rates and Borrowing Capacity for Portfolio Growth
When you apply to borrow for a second or third investment property, lenders assess your existing commitments using specific serviceability buffers. For variable rate loans, they typically assess your capacity based on the current rate plus a buffer of 2-3%. For fixed rate loans, some lenders assess based on the actual fixed rate, while others still apply the buffered variable rate regardless of what you're actually paying.
This creates a scenario where fixing your rate may not improve your borrowing capacity as much as you'd expect, even though your actual repayments are lower and more certain. A property investor in Richmond holding two investment properties might have fixed both loans to control cash flow, only to discover when applying for a third property that the lender is assessing serviceability as if both loans were on variable rates. Their actual capacity to service the debt is stronger than the assessment suggests, but the lender's policy doesn't reflect that reality.
Some lenders do recognise fixed rate commitments at the actual fixed rate for serviceability purposes, particularly if the fixed period has substantial time remaining. When planning portfolio growth, understanding which lenders assess fixed loans more favourably can determine whether your next purchase is approved or declined. This is where accessing investment loan options from banks and lenders across Australia becomes relevant, rather than staying with a single lender whose serviceability approach may limit your capacity.
When Fixed Rates Make Sense for Richmond Investors
Fixed rates suit investors who prioritise cash flow certainty and intend to hold the property throughout the fixed period without major changes to their financial position. Richmond's rental market, with its proximity to the CBD, established public transport along Church Street and Swan Street, and strong demand from young professionals, typically provides consistent rental income that supports a fixed repayment structure.
If you're entering the market with limited surplus income and need to know your maximum financial commitment, fixing provides that certainty. If rates rise during your fixed period, you benefit from having locked in a lower rate. If rates fall, you'll be paying above market, but the cost of that protection was the trade-off you accepted for certainty.
Fixed rates also make sense when you're using the investment property to build wealth through capital growth and rental income combined, rather than planning to actively pay down the loan or access equity frequently. An investor using a principal and interest loan structure who intends to hold for ten years but wants rate protection for the first three to five years can fix without significantly compromising their long-term strategy.
If your plans include potentially selling the property, refinancing to access equity, or making substantial lump sum repayments within the next few years, variable or split structures offer more flexibility without the risk of break costs derailing your strategy. Use the fixed rate expiry calculator to understand when your fixed term will end and what your likely position will be at that point.

Frequently Asked Questions
Can I make extra repayments on a fixed rate investment loan?
Most fixed rate investment loans allow limited additional repayments, typically $10,000 to $30,000 per year, without penalty. Exceeding this limit usually triggers break costs, which compensate the lender for the rate difference and can amount to thousands of dollars.
Do fixed rate investment loans offer offset accounts?
Most fixed rate investment loans do not offer full offset account functionality. Some lenders provide partial offsets or redraw facilities instead, but these don't deliver the same daily interest reduction that a 100% offset account on a variable loan provides.
What happens when my fixed rate period ends?
When your fixed term expires, you can either refix at the current rate offered by your lender or revert to their standard variable rate. This is also an opportunity to refinance to a different lender if better rates or features are available elsewhere.
How does fixing my investment loan rate affect borrowing capacity for my next property?
Some lenders assess fixed rate loans at the actual fixed rate for serviceability, while others apply the same buffered variable rate assessment regardless of what you're paying. This means fixing your rate may not improve borrowing capacity as much as expected when applying for additional properties.
Should I split my investment loan between fixed and variable?
A split loan structure provides rate certainty on the fixed portion while maintaining flexibility for extra repayments and offset benefits on the variable portion. This approach suits investors who want some protection from rate rises without sacrificing all flexibility for future changes.
