Home loan features to compare before you look at the rate

The advertised rate is the easiest number to compare and the least complete one. Two loans with near-identical rates can differ by thousands of dollars over the life of the loan once you account for fees, how the loan handles extra repayments, and whether the structure actually fits how you are paid and how you spend.

This guide is about reordering the work: get the right documents first, compare structure second, and only then use the rate as the tiebreaker.

Why the rate is the wrong place to start

Moneysmart, the Australian Securities and Investments Commission's consumer money site, makes the scale of the decision plain: "Your home loan (mortgage) might be the biggest debt – for the longest period of time – that you ever have."

That length is what makes structure matter. A small headline discount on a loan that charges ongoing fees, blocks offset, or locks you out of extra repayments can cost you more than the discount saves. Moneysmart also notes that "small differences in your mortgage interest rate can make a big difference to the long-term cost of your home loan" — which cuts both ways. Rate matters, but it matters after you know what else you are buying.

Start with the Key Fact Sheet, not a comparison headline

Moneysmart's core instruction is procedural: "For all home loans you want to compare, get the Key Fact Sheet for that loan, based on the amount you're likely to borrow." Then: "Once you've got the Key Fact Sheets for all the loans you're considering, compare these features."

Two details in that instruction are easy to miss:

• Get it for your amount. A Key Fact Sheet is generated for a specific loan size. A sheet produced for a $400,000 example may not reflect the fees or repayments that apply to your actual borrowing.
• One sheet per loan. Comparison only works when every loan is documented the same way, at the same amount, on the same date.

Ask the lender directly for the Key Fact Sheet if it is not offered. Treat a marketing rate with no Key Fact Sheet behind it as an incomplete quote, not a comparable one.

Run the numbers before you judge the rate

Moneysmart points readers to its mortgage calculator to "work out what your repayments would be - and what the total cost of your home loan would be - depending on the interest rate and the length of the loan."

Use it on each loan with the same inputs: your borrowing amount, the same loan term, and the rate from that loan's Key Fact Sheet. Comparing total cost rather than monthly repayment is the point — a longer term lowers the repayment while raising the total, which is exactly the trade-off a headline comparison hides.

The features to put on your list

Below is a practical checklist. The right-hand column is what you need to confirm with the lender, because these mechanics are set by the individual loan contract.

Feature	What it does	Confirm with the lender
Offset account	A linked account whose balance is typically deducted from the loan balance when interest is calculated	Is it full or partial offset? Is there a fee? Does it apply to fixed-rate portions?
Redraw facility	Lets you withdraw extra repayments you have already made	Any minimum redraw, fee, or limit? Can the lender refuse or reduce it?
Ongoing fees	Annual or monthly charges that sit outside the rate	What are they, and do they apply for the life of the loan?
Upfront fees	Application, valuation and settlement costs	Which are charged, and are any waived or capped?
Extra repayments	Paying more than the minimum	Allowed without penalty? Any annual cap?
Repayment type	Principal and interest, or interest-only for a period	What happens to repayments when any interest-only period ends?
Fixed vs variable	Whether the rate can move	What is the rate after any fixed period ends? Are there break costs?
Split loans	Dividing the loan into fixed and variable portions	Is splitting free? Can you re-split later?
Loan term	The length of the contract	Does a shorter term suit your cash flow? Can you change it?
Portability	Moving the loan to a new property	Is it portable, or would you need to refinance?
Exit / discharge fees	Cost of leaving or paying out early	What is charged at discharge, and when?

Fees are the quietest line item

A rate is expressed as a percentage; fees are expressed as dollars. That difference is why fees get underweighted. A loan with a slightly higher rate and no ongoing fee can come out ahead of a cheaper-rate loan with an annual charge, and the answer depends entirely on your loan size and how long you hold it.

Read the Key Fact Sheet for the dollar figures rather than relying on a product summary, and check three things: what is charged upfront, what is charged on a recurring basis, and what is charged when you leave.

Offset, redraw and extra repayments: how to think about them

These three mechanisms all involve money you put into the loan, but they behave differently in practice.

• Offset keeps your money accessible in a linked account while it affects the balance interest is calculated on. Useful if you hold cash you may need — a buffer, irregular income, or savings you do not want to commit permanently.
• Redraw means extra repayments reduce the loan, and you may be able to take them back later. Whether you can, at what cost, and under what conditions is a contract term, not a standard feature.
• Extra repayments permanently reduce the balance. Whether they are permitted without penalty, and whether the lender recalculates the minimum repayment afterwards, should be confirmed before you rely on them.

The practical question is not which is "better" in the abstract, but which one you will actually use given how your income arrives. An offset account you never fund delivers nothing, and a redraw you cannot access is not a buffer.

Structure choices that follow from the loan term

Moneysmart's calculator takes the loan length as an input alongside the rate, which is a reminder that term is a structural decision, not a default. A shorter term raises the repayment and lowers total interest; a longer term does the reverse. Neither is correct in isolation — it depends on whether your budget can absorb the higher repayment through the conditions you would actually face, including rate movement.

If you are considering a fixed rate, the questions that matter are what happens at the end of the fixed period, whether you can make extra repayments while fixed, and what breaking the fixed term would cost. If you are splitting, confirm whether splitting and re-splitting carry fees.

One further note from Moneysmart's home loan guidance: Islamic finance products exist in Australia. If a faith-based structure matters to you, raise it with lenders directly, since product availability differs by provider.

Your next step: a repeatable comparison routine

1. Shortlist two to four loans — enough to compare, few enough to finish.
2. Request the Key Fact Sheet for each, generated at the amount you intend to borrow.
3. Put the upfront fees, ongoing fees and exit fees side by side in dollars.
4. Note whether each loan has offset, redraw, and unrestricted extra repayments — and any conditions attached.
5. Run the same amount and term through Moneysmart's mortgage calculator for each loan, and compare total cost, not just the repayment.
6. Only now compare rates. If two loans are close on structure, the rate decides it.

If your situation involves a variable income, a deposit from family, a guarantor, or a purchase through a trust or company structure, the checklist above is a starting point, not the whole picture — those arrangements warrant advice from someone who can see your full circumstances.
