Top tips to choose Fixed Rate Terms for Investment Loans

Fixed rate terms on an investment loan protect you from rate rises during the fixed period, but the choice of one, two, three or five years changes how much flexibility you retain and how the loan supports your broader strategy.

How Fixed Rate Terms Work on Investment Property Loans

A fixed rate term locks your interest rate for a set period, typically one to five years. During that period, your repayments remain constant regardless of movements in the Reserve Bank cash rate or lender variable rates. At the end of the fixed term, the loan reverts to the lender's standard variable rate unless you refinance or negotiate a new fixed term.

For self-employed investors in Sydney, the stability of a fixed rate can make budgeting more predictable, particularly when rental income fluctuates or you are managing business cash flow alongside property commitments. The challenge is that most fixed rate investment loans restrict additional repayments, limit access to redraw facilities, and impose break costs if you need to exit the loan early.

Choosing Between One, Three and Five Year Fixed Terms

Shorter fixed terms offer more flexibility. A one-year fix gives you certainty for the immediate term without locking you into a rate that may become uncompetitive if the market moves in your favour. If you expect your business income to increase, plan to refinance within the next 18 months, or anticipate selling the property to upgrade your portfolio, a one-year term allows you to adjust without penalty.

Three-year fixed terms are the most common choice among property investors. They balance rate protection with a manageable commitment period. If you are holding a property for income and medium-term capital growth, a three-year term aligns with typical portfolio review cycles and gives you time to assess whether the asset still fits your strategy.

Five-year fixed terms are less common on investment loans. They suit investors who want maximum certainty and have no intention of selling, refinancing or restructuring debt during that period. The downside is that break costs on a five-year fixed loan can be substantial if rates fall or if your circumstances change and you need to access equity or move lenders.

Break Costs and Why They Matter More for Investors

Break costs apply when you exit a fixed rate loan before the term ends. They are calculated based on the difference between the rate you are paying and the rate the lender can now charge on funds for the remaining fixed period. If rates have fallen since you fixed, you will owe the lender the lost margin.

For investors, break costs are a larger consideration than they are for owner-occupiers because investment property decisions are often driven by portfolio changes, refinancing to access equity, or restructuring debt to fund the next acquisition. A self-employed buyer who fixes for five years and then decides to consolidate business and investment debt two years later may face break costs that wipe out any benefit the fixed rate delivered.

Consider an investor who fixed a loan on a two-bedroom unit in Parramatta at 5.8 per cent for five years. Two years into the term, they want to release equity to buy a second property. The lender's three-year fixed rate has since dropped to 5.1 per cent. The break cost is calculated on the 0.7 per cent difference, applied to the remaining three years of the fixed term. On a loan balance of $600,000, that break cost could exceed $12,000. The investor either pays the cost to proceed or delays the purchase until the fixed term expires.

Split Rate Structures and How They Reduce Risk

A split loan divides your borrowing between fixed and variable portions. You might fix 50 per cent of the loan for three years and leave the other 50 per cent variable. This structure gives you some rate protection while preserving the ability to make additional repayments and access a redraw facility on the variable portion.

For self-employed investors, a split can smooth the impact of income variability. In months when your business generates higher cash flow, you can make extra repayments into the variable portion and reduce your interest cost. In leaner months, you rely on the fixed portion to keep repayments predictable.

If you later decide to refinance or restructure, break costs apply only to the fixed portion. You can repay the variable portion in full without penalty. This structure also allows you to test how much flexibility you actually need. If you find you rarely make additional repayments, you can shift more of the loan to fixed when the current term expires. If you regularly pay ahead, you can increase the variable portion.

Interest Only Periods and Fixed Rate Terms

Many investors choose interest only repayments to maximise cash flow and tax deductions. When you combine interest only with a fixed rate, you need to confirm that the interest only period and the fixed term are aligned. Some lenders offer a five-year interest only period but only a three-year fixed term. At the end of year three, the loan reverts to variable and the rate may increase, even though you still have two years of interest only repayments remaining.

If the interest only period expires before the fixed term ends, the loan converts to principal and interest repayments while still fixed. Your repayment amount will increase mid-term, which can affect cash flow if you have not planned for it. When structuring an investment loan with both interest only and a fixed rate, align the two periods or choose a shorter fixed term that ends before the interest only period expires.

How Lenders Assess Fixed Rate Applications for Self-Employed Investors

Lenders apply the same serviceability assessment to fixed and variable rate applications, but the way they assess self-employed income can affect your borrowing capacity. Most lenders require two full years of tax returns and average your net business income over that period. If your most recent year shows lower income due to business investment or temporary disruption, the lender may reduce the assessable income, which reduces the loan amount you can access.

Some lenders offer more flexibility for self-employed applicants by using the most recent year's income if it is higher, or by allowing business accountants to provide a profit and loss statement that reflects current trading. When you fix a rate, you also fix your borrowing capacity for the term. If your income increases during the fixed period and you want to borrow more, you will either need to refinance and pay break costs or wait until the fixed term expires.

Working with a broker who understands how different lenders assess self-employed income can open access to loan products and fixed rate terms that align with your current financial position and future plans. Our role is to match your circumstances to the lender whose policies work in your favour, not the other way around.

Rate Locks and When to Use Them

A rate lock allows you to secure a fixed rate before settlement, typically for 90 days. If you are buying an investment property off the plan or building a new dwelling, a rate lock protects you from rate increases during construction. If rates rise after you lock, you benefit. If rates fall, you are locked in and cannot access the lower rate without forfeiting the lock.

Rate locks are less useful for established property purchases with a short settlement period. If you lock a rate and settlement is delayed, the lock may expire and you will need to reapply at the current rate. Some lenders charge a fee to extend a rate lock. Others do not offer locks at all on investment loans.

If you are self-employed and your financials are time-sensitive, a rate lock can also create risk. If your income changes between the lock date and settlement, the lender may reassess serviceability and reduce the approved loan amount, even though the rate is locked. The lock guarantees the rate, not the loan amount.

What Happens When Your Fixed Term Ends

When your fixed term expires, the loan automatically reverts to the lender's variable rate unless you contact the lender to negotiate a new rate or refinance to another lender. The variable rate you revert to is often higher than the lender's current advertised variable rate for new customers. Lenders typically contact you 30 to 60 days before the fixed term ends to offer a new fixed or variable rate, but the rates offered to existing customers are rarely the sharpest available.

This is when working with a broker becomes particularly valuable. We monitor fixed rate expiry dates for our clients and begin refinancing discussions three to four months before the term ends. If your current lender offers a competitive retention rate, we negotiate on your behalf. If another lender offers a lower rate or better features, we manage the refinance process so you move to the new loan as soon as the fixed term expires, without paying break costs or reverting to a higher variable rate.

For investors with multiple properties, staggering fixed rate expiry dates across your portfolio reduces the risk that all your loans revert to variable at the same time during a rising rate cycle. If you have three investment properties, you might fix one for two years, one for three years, and one for four years, so each loan can be reviewed and refinanced independently as market conditions change.

Call one of our team or book an appointment at a time that works for you. We will review your current investment property loans, assess whether a fixed rate term suits your portfolio, and structure the loan so it supports your long-term strategy without locking you into a position that limits your options down the track.
