How to Read a Home Loan Contract: Key Terms Every Borrower Should Understand

Signing a home loan contract is one of the most significant financial commitments most Australians will ever make. Yet the loan documents arrive in a thick packet of dense legal language, often just days before settlement, and most borrowers sign without fully understanding what they are agreeing to.

This guide walks through the key sections and terms in a home loan contract so that you know what to look for, what questions to ask and what to be cautious about before you sign.

What Documents Are Involved?

A home loan signing typically involves several documents.

The Loan Contract (Credit Contract): the binding agreement between you and the lender setting out all the financial and legal terms of the loan.

The Mortgage Document: the document that registers the lender's security interest over your property on the title. This is what gives the lender the right to sell the property if you default.

The Letter of Offer: a summary document confirming the key loan terms. Read this carefully as a starting point.

Depending on the lender and loan type, there may also be a guarantee document (if a guarantor is involved), a direct debit authority and privacy consent forms.

Key Terms to Understand in the Loan Contract

Loan Amount

The principal amount being lent. Confirm this matches your application exactly. If you are rolling in fees like LMI, the loan amount will be higher than the purchase price less your deposit.

Interest Rate

Note both the initial interest rate and the type: variable, fixed or split. For fixed rate loans, note the fixed term clearly and what the rate reverts to at the end of the fixed period. The revert rate is critically important and is sometimes buried. A competitive fixed rate followed by an uncompetitive revert variable rate can cost you significantly if you do not refinance promptly.

Comparison Rate

Required by law to appear alongside the advertised interest rate. As covered in our separate guide, the comparison rate provides a more complete view of loan cost by incorporating fees, though it has limitations.

Repayment Amount and Frequency

Confirm your required repayment amount and whether it is weekly, fortnightly or monthly. Note whether the repayment shown is principal and interest or interest only.

Loan Term

Usually 25 or 30 years. Note the scheduled end date of the loan under the standard repayment arrangement.

Break Costs (Fixed Rate Loans)

For fixed rate loans, this is one of the most important clauses. The contract will describe how break costs are calculated if you exit the fixed rate period early, whether by refinancing, selling or making a full payout. Break costs are typically not a fixed dollar amount. They are calculated based on the difference between your fixed rate and the current wholesale market rate for the remaining fixed term, which means they can be very large in a falling rate environment.

Ask your lender for a realistic illustrative break cost based on current conditions when you sign, so you understand the scale of the potential penalty.

Fees

The contract must disclose all fees. Look for:

Application or establishment fees.

Monthly or annual account-keeping fees.

Valuation fees.

Discharge fee (payable when you pay out the loan, which applies even in refinancing).

Redraw fees (some lenders charge per redraw transaction).

Late payment fees.

Offset Account Terms

If your loan comes with an offset account, the contract will describe how it works. Confirm that interest is calculated daily based on the offset balance and credited monthly. Some offset accounts are not genuine offset accounts but are instead linked savings accounts with limited offset functionality.

Redraw Facility

If the loan has a redraw facility, the contract will specify the minimum redraw amount, any fees that apply and any other conditions. Note that unlike an offset account, funds in redraw are legally owned by the lender until drawn down.

LMI Terms (if applicable)

If you are paying LMI, the contract will include the premium amount and whether it is being added to the loan or paid upfront. It will also reference that LMI protects the lender, not you.

Default and Enforcement

This section describes what constitutes a default and what the lender's rights are. In Australia, lenders must follow the requirements of the National Consumer Credit Protection Act and provide formal notices before taking enforcement action. They must also consider and respond to hardship applications. Understanding this section removes uncertainty if you ever face difficulties.

What to Check Before You Sign

Compare the key terms in the contract against what you were quoted at pre-approval. If the rate, loan amount, fees or other terms have changed, ask for an explanation before you sign.

Read the fixed rate revert clause carefully if you are taking a fixed rate. Know what your rate becomes after the fixed term.

Confirm the discharge fee. This applies when you pay out the loan and is charged even when refinancing. On top of break costs for a fixed loan, the discharge fee adds to the cost of switching.

Ask about the cooling-off period. Under the National Consumer Credit Protection Act, you typically have a short period after signing a credit contract to withdraw without penalty, though this does not apply to some contract types. Ask your lender or broker to confirm.

Getting Help

Your mortgage broker should walk you through the key terms of the loan documents before you sign. If you are applying directly without a broker, ask the lender's representative to explain any terms you are uncertain about.

If you need formal legal advice on the loan contract, a solicitor or licensed conveyancer can review it. The cost is modest compared with the commitment you are making.
