Do you know what's hidden in your loan terms?

Your home loan contract includes dozens of features and conditions that shape how much you pay and what you can do with your property over the next 30 years.

Most borrowers focus entirely on the interest rate when comparing home loan products, but the terms and conditions determine whether you can make extra repayments without penalty, move house without refinancing, or access your equity when you need it. A loan with a slightly higher rate and better features often costs less over time than a restricted product with a headline-grabbing rate.

Redraw Facilities and Offset Accounts Work Differently

A redraw facility lets you access extra repayments you've made on your loan, while an offset account is a separate transaction account where your balance reduces the interest charged on your mortgage.

Consider a buyer in Lakelands who borrows $550,000 on a variable rate with a linked offset account. They keep $40,000 in the offset, which means they only pay interest on $510,000 while maintaining full access to that $40,000 for emergencies or opportunities. If the same buyer chose a loan with redraw instead, they'd need to apply each time they wanted access, and some lenders place limits on how much you can withdraw or charge fees for each transaction. The offset account also protects those funds from being counted as a repayment for tax purposes, which matters if you later convert the property to an investment.

Not every loan package includes an offset account, and those that do may limit the number of accounts or charge annual fees. A redraw facility often comes standard on variable rate loans but can be restricted or removed entirely on fixed rate products.

Fixed Rate Break Costs Are Calculated on Wholesale Rates

Breaking a fixed rate home loan before the term ends triggers a break cost, which is calculated based on the difference between your fixed interest rate and the lender's current wholesale cost of funds.

If you fixed at 4.5% for three years and wholesale rates have since dropped to 3.8%, the lender charges you for the interest they'll lose over the remaining term. On a $500,000 loan with two years left, that break cost could be $7,000 or more. If rates have risen since you fixed, the break cost may be zero because the lender can re-lend your funds at a higher rate.

This calculation varies between lenders, and some home loan products include portability clauses that let you transfer your fixed rate to a new property without paying break costs. If you're buying in Mandurah or planning to upsize in the next few years, a portable loan gives you the option to move without penalty. We regularly see borrowers locked into properties or forced to pay thousands in break costs because they didn't check this feature when they fixed their rate.

Split Rate Loans Give You Control Over Interest Rate Risk

A split loan divides your mortgage into two portions, with one on a variable interest rate and the other fixed for a set term.

In a scenario where a couple in Rockingham borrows $600,000, they might fix $300,000 at 5.2% for three years and leave $300,000 on a variable rate currently sitting at 6.1%. If variable rates drop, they benefit immediately on half the loan and still have the certainty of fixed repayments on the other half. If rates rise, they're protected on the fixed portion. The variable portion usually allows unlimited extra repayments and full redraw or offset access, while the fixed portion locks them in but provides certainty.

The split ratio can be adjusted to suit your risk tolerance. Some borrowers prefer a 70/30 split weighted toward fixed if they value certainty, while others go 30/70 if they want flexibility and believe rates will fall. You can also stagger the fixed terms, fixing one portion for two years and another for four, so they expire at different times and you're never fully exposed to rate movements at once.

Interest Only Repayments Reduce Cash Flow Pressure But Don't Build Equity

An interest only loan requires you to pay only the interest charged each month, with no reduction to the principal loan amount during the interest only period.

This feature is common on investment loans where borrowers want to maximise tax deductions and use their cash flow to build other assets or pay down owner occupied debt. On a $450,000 loan at 6.0%, the interest only repayment is around $2,250 per month compared to $2,698 for principal and interest. That difference of $448 per month can be redirected toward your owner occupied home loan or saved for the next deposit.

Most lenders limit interest only terms to five years on an owner occupied home loan and up to ten years on investment loans. Once the interest only period ends, the loan reverts to principal and interest, and your repayments increase because you're now paying down the loan amount over a shorter remaining term. If you've done nothing to reduce the balance during the interest only period, you're back where you started but with fewer years to repay.

Loan to Value Ratio Determines Your Interest Rate Discount

Your loan to value ratio is the amount you borrow divided by the property value, expressed as a percentage, and it directly affects the interest rate and features available to you.

A borrower in Secret Harbour with a 20% deposit on a $650,000 property has an 80% LVR and qualifies for standard rate discounts and full access to offset accounts and flexible features. If the same buyer only has a 10% deposit, their LVR is 90%, which means they'll pay Lenders Mortgage Insurance and receive a smaller rate discount, often 0.2% to 0.5% higher. Some lenders also restrict access to offset accounts or limit extra repayments at higher LVR levels.

If you're refinancing and your property has increased in value, your LVR may have dropped since you first borrowed, which can unlock lower rates and additional features. Calculating your current LVR before applying gives you a clear picture of what home loan options are available and whether it's worth waiting to build more equity before refinancing.

Loan Portability Lets You Move Without Refinancing

A portable loan allows you to transfer your existing home loan to a new property without breaking the contract or reapplying from scratch.

This feature is particularly useful if you're on a fixed interest rate and want to move house before the term ends. Instead of paying break costs, you port the loan to the new property and keep the same rate and conditions. If you're borrowing more for the new property, the additional amount is usually added as a separate loan or charged at current rates, but your original fixed rate continues on the ported portion.

Not all lenders offer portability, and those that do may impose conditions such as requiring the new property to be within a certain price range or settling within a specific timeframe. If you're buying in growth areas like Baldivis or planning to upsize within a few years, checking whether your loan includes this feature can save you thousands in break costs and application fees.

Extra Repayments Can Be Restricted on Fixed Rates

Most variable rate home loan products allow unlimited extra repayments with full redraw access, but fixed rate loans often cap extra repayments at $10,000 to $30,000 per year without penalty.

If you exceed that limit, the lender may treat it as a partial break of the fixed rate and charge you based on the same wholesale rate calculation used for full break costs. A buyer in Halls Head who fixed $400,000 at 5.0% and later receives a $50,000 inheritance might only be able to pay down $20,000 without penalty, leaving the remaining $30,000 sitting in a savings account earning 4.0% while the loan costs 5.0%.

Some fixed rate products allow unlimited extra repayments but don't offer redraw, which means once you've paid extra, you can't access those funds again until the fixed term ends. If you value flexibility and expect to have surplus cash flow, a variable rate or split loan structure gives you more control over your repayments and access to those funds.
