Beginner's Guide to Variable Rate Investment Loans

A variable rate investment loan with an offset or redraw facility gives you flexibility that a fixed loan does not.

The ability to make extra repayments means you can reduce your loan balance faster during strong rental periods, then draw those funds if you need to cover a vacancy or capital improvement. That access matters in a suburb like Strathfield, where rental vacancy periods can stretch longer than expected when tenants leave between school terms or university semesters.

Why Variable Rate Loans Suit Strathfield Investors

Variable rates move with the Reserve Bank cash rate, which means your repayments can fall when rates drop. Strathfield attracts families and students looking for proximity to schools, Strathfield station, and Westfield shopping, so demand remains steady. A variable loan lets you respond to rate changes without refinancing penalties, and you can make unlimited extra repayments without triggering break costs.

Consider an investor who purchases a two-bedroom apartment near The Boulevarde and secures a tenant before settlement. During the first 18 months, rental income exceeds the loan repayment by around $200 per week. Instead of taking that surplus as income, the investor directs it into an offset account linked to the loan. When the tenant leaves to return overseas, the investor draws from the offset to cover two months of vacancy without needing to find cash from their own salary. The loan balance stayed lower during the rental period, which saved interest, and the offset provided a buffer when income stopped.

How Extra Repayments Reduce Interest Without Losing Access

Extra repayments reduce the loan principal, which lowers the interest charged each month. On a variable rate loan, you can make those repayments through an offset account or redraw facility. An offset account is a transaction account linked to your loan. Every dollar in the account reduces the balance on which interest is calculated, but you can withdraw the funds at any time. A redraw facility allows you to make extra repayments directly into the loan, then withdraw them later if needed.

The difference between the two is access and tax treatment. Offset accounts keep your funds separate, so withdrawals do not create a tax issue. Redraw funds are technically loan repayments, so if you redraw for a private purpose, the interest on that redrawn amount may no longer be deductible. If you plan to use the funds for non-investment purposes, an offset is the safer choice.

In Strathfield, where body corporate fees and council rates for units can run higher than newer suburbs, having cash available without refinancing or applying for a top-up helps you manage unexpected levies or repairs. A variable loan with offset or redraw gives you that access without locking you into a product you cannot adjust.

Interest-Only or Principal-and-Interest Repayments

Most variable rate investment loans offer a choice between interest-only and principal-and-interest repayments. Interest-only repayments are lower, which maximises short-term cash flow and can increase your borrowing capacity when you apply. The downside is that your loan balance does not reduce, so you pay more interest over the life of the loan and build equity more slowly.

Principal-and-interest repayments are higher, but every payment reduces the loan balance. That reduction builds equity faster and lowers your total interest cost. If you plan to hold the property long-term and want to own it outright before retirement, principal-and-interest repayments make sense.

You can also structure the loan as interest-only and make voluntary principal repayments into an offset or redraw. This gives you the lower minimum repayment of an interest-only loan with the equity-building benefit of principal-and-interest, and you retain access to the extra funds if you need them. That structure works well in Strathfield, where rental yields are moderate but capital growth has been consistent. You can build equity without committing to higher fixed repayments.

What Happens When You Refinance or Draw Equity

If you make extra repayments and later want to access that equity for another purchase, you can refinance or apply for an equity release. Refinancing means replacing your current loan with a new one, usually to access a lower rate or better features. Equity release means borrowing against the increased value of your property or the principal you have repaid.

Both options require a new application and serviceability assessment, so the lender will review your income, expenses, and rental income at that time. If you have reduced your loan balance through extra repayments, your loan-to-value ratio improves, which can help you avoid Lenders Mortgage Insurance on the new loan.

In our experience, Strathfield investors who make consistent extra repayments during the first few years can access equity for a second purchase without needing to sell the first property. That strategy relies on rental income remaining stable and property values holding or increasing. If you are planning to build a portfolio, keeping your loan structure flexible from the start makes the second purchase much smoother.

Tax Considerations for Extra Repayments and Redraw

Interest on an investment loan is deductible if the loan is used to purchase or hold a property that produces assessable income. If you make extra repayments and later redraw for a private purpose, the interest on that redrawn amount is not deductible. The ATO treats the redrawn portion as a separate loan for a different purpose.

An offset account avoids this issue because the funds are never treated as loan repayments. The account reduces the interest you pay, but withdrawing from the offset does not change the purpose of the underlying loan. If you think you might use the funds for personal expenses or a property renovation that does not increase rental income, an offset is the safer structure.

For Strathfield investors holding properties under the current negative gearing rules, interest deductions remain valuable. Properties purchased before 7:30pm AEST on 12 May 2026 continue under existing tax treatment, so maximising deductible interest while retaining access to surplus cash makes sense. A variable loan with offset gives you both.

Choosing Between Variable and Fixed for Strathfield Investment Property

A fixed rate loan locks your rate for a set period, usually one to five years. Fixed loans provide certainty, but they do not allow extra repayments beyond a small annual cap, and you cannot access redraw or offset during the fixed period. If you break the loan early, you may face significant break costs.

A variable loan gives you flexibility to make extra repayments, access those funds, and refinance without penalty. If you expect rental income to fluctuate or plan to sell within a few years, a variable loan is usually the right choice. If you want to lock in a rate and are confident you will not need access to extra funds, a fixed loan works.

Many investors split their loan, fixing part and leaving part variable. That structure gives you some rate protection while retaining flexibility on the variable portion. A split works well if you want to make extra repayments but also want to hedge against rate increases. For Strathfield properties, where rental demand is steady but tenant turnover can be unpredictable, keeping at least half the loan variable gives you room to manage vacancies and repairs without refinancing.

You can explore refinancing options if your current loan does not offer the features you need, or speak with a mortgage broker in Strathfield who understands the local rental market and can recommend lenders with strong offset and redraw products.

How Lenders Assess Investment Loan Applications with Extra Repayment Features

Lenders assess your ability to service the loan based on your income, existing debts, and the rental income the property is expected to generate. Most lenders apply a discount to rental income, usually 80 per cent, to account for vacancies and management costs. They also test your serviceability at a rate 3 percentage points above the actual loan rate, which is the current APRA buffer.

If you want an offset account or redraw facility, some lenders charge a higher rate or annual fee. The cost is usually small, but it is worth comparing. A variable loan with offset typically sits around 0.10 to 0.20 percentage points higher than a basic variable loan without offset, depending on the lender and your deposit size.

For Strathfield investors, rental income from a two-bedroom unit near the station or a three-bedroom house in the North Strathfield school catchment is usually enough to support a loan at 80 per cent loan-to-value ratio, assuming you have other income to cover the shortfall. If you are relying on rental income alone, lenders will want to see a low vacancy rate and a strong rental history.

If you are purchasing your first investment property, you can compare investment loan options across lenders to find a variable product with the features you need. Some lenders offer rate discounts for new investment loans, particularly if you have a deposit above 20 per cent and a clean credit history.
