Australian Mortgage Glossary: 80+ Terms Every Borrower Should Know

Loan Structure and Product Terms (A–F)

Amortisation: The process of paying off a loan through regular scheduled repayments of principal and interest over the loan term. A 30-year amortisation means the loan is designed to be fully repaid in 30 years of regular payments.

APRA (Australian Prudential Regulation Authority): The government body that regulates banks, credit unions, and other deposit-taking institutions. APRA sets rules that affect how lenders assess home loan applications — including the serviceability buffer (currently 3%) that requires borrowers to demonstrate they can afford repayments at a rate 3% above their actual rate.

Basic Variable Rate: A no-frills variable rate home loan with fewer features (no offset, limited or no redraw) but a lower interest rate than full-featured products. Suitable for borrowers who want the lowest possible rate and do not need offset or package features.

Bridging Loan: A short-term loan that allows you to purchase a new property before selling your existing one. Interest is typically capitalised (added to the loan) during the bridging period.

Comparison Rate: A rate that includes both the interest rate and standard fees, expressed as a single percentage. Designed to help borrowers compare the true cost of different loan products. Calculated on a $150,000 loan over 25 years by law.

Construction Loan: A home loan for building a new home, where funds are drawn down in stages (progress payments) as construction progresses. Interest is only charged on the drawn amount during construction.

Cross-Collateralisation: Using multiple properties as security for a single loan (or group of loans with the same lender). Common with investment portfolios but can create complications if you want to sell one property or change lenders.

Deposit Bond: A guarantee from an insurance company that acts as a substitute for a cash deposit at auction or exchange. The actual cash deposit is paid at settlement.

Discharge: The process of removing a mortgage from a property title when the loan is paid off or refinanced. Lenders charge a discharge fee ($150–$400).

Equity: The difference between your property's current market value and the outstanding mortgage balance. If your property is worth $800,000 and you owe $500,000, your equity is $300,000.

Fixed Rate: An interest rate that is locked in for a specified period (typically 1–5 years). Repayments remain the same regardless of market rate changes during the fixed period. Break costs may apply if you exit early.

Full-Doc Loan: A home loan where full income and financial documentation is provided (payslips, tax returns, bank statements). Offers the best rates and highest borrowing capacity compared to low-doc or alt-doc products.

Assessment, Approval, and Ownership Terms (G–P)

Genuine Savings: Funds that you have saved over time (typically 3–6 months of regular savings visible in your bank statements). Some lenders require genuine savings as part of the deposit — gifted funds, tax refunds, or sale proceeds do not count as genuine savings.

Guarantor: A person (typically a family member) who provides additional security for a home loan by pledging equity in their own property. This allows the borrower to avoid LMI or borrow with a smaller deposit.

Hardship Variation: A temporary change to loan terms (reduced repayments, payment pause, extended term) granted by a lender to a borrower experiencing financial difficulty.

Interest-Only (IO): A repayment structure where you pay only the interest on the loan — not the principal — for a specified period (typically 1–5 years). Monthly repayments are lower, but the loan balance does not decrease. Commonly used by property investors.

Joint Tenancy: A form of property co-ownership where all owners hold equal shares. If one owner dies, their share automatically passes to the surviving owner(s) (right of survivorship).

LMI (Lenders Mortgage Insurance): A one-off insurance premium required when the LVR exceeds 80%. LMI protects the lender (not the borrower) against loss if the borrower defaults and the property is sold for less than the loan balance. Premiums range from $2,000 to $40,000+.

Low-Doc Loan: A home loan for borrowers (typically self-employed) who cannot provide standard income documentation. Instead of tax returns, income is verified through BAS statements, bank statements, or an accountant's letter. Higher rates and lower LVR limits apply.

LVR (Loan-to-Value Ratio): The loan amount expressed as a percentage of the property value. A $400,000 loan on a $500,000 property = 80% LVR. LVR determines LMI requirements, interest rate pricing, and product eligibility.

Mortgagee: The lender — the party that holds the mortgage security over the property.

Mortgagor: The borrower — the party that grants the mortgage to the lender.

Negative Gearing: An investment strategy where the costs of owning a rental property exceed the rental income, creating a tax-deductible loss that reduces your overall taxable income.

Offset Account: A transaction account linked to your home loan. The balance in the offset reduces the loan principal for interest calculation purposes. $50,000 in an offset on a $500,000 loan means interest is calculated on $450,000.

Pre-Approval (Conditional Approval): A preliminary assessment by a lender confirming that you can borrow up to a specified amount, subject to property valuation and final verification. Typically valid for 3–6 months.

Principal: The original loan amount borrowed — excluding interest. As you make repayments, the principal reduces (assuming P&I repayments).

Principal and Interest (P&I): A repayment structure where each payment covers a portion of the principal (reducing the loan balance) and a portion of the interest charged. The most common repayment type for owner-occupied loans.

Rates, Fees, Government, and Regulatory Terms (Q–Z)

RBA (Reserve Bank of Australia): Australia's central bank, which sets the official cash rate. The cash rate directly influences home loan interest rates — when the RBA raises or lowers the cash rate, lenders typically adjust their variable rates accordingly.

Redraw Facility: A feature that allows you to withdraw additional repayments you have made above the minimum required. Similar to an offset account in effect, but with less flexibility — funds are 'inside' the loan rather than in a separate account.

Refinancing: The process of replacing your existing home loan with a new loan — either with the same lender (internal refinance) or a different lender (external refinance). Commonly done to secure a lower interest rate, access equity, or change loan features.

Serviceability: The lender's assessment of whether you can afford the loan repayments. Calculated using your income, expenses, existing debts, and a buffer rate (currently 3% above the loan rate, as mandated by APRA).

Serviceability Buffer: The additional percentage (currently 3%) that APRA requires lenders to add to the loan interest rate when assessing borrowing capacity. If the loan rate is 6.5%, the lender must assess whether you can afford repayments at 9.5%. This ensures borrowers can withstand rate increases.

Settlement: The legal process of transferring property ownership from seller to buyer. The lender disburses the loan funds, the buyer's conveyancer pays the seller, and the property title is transferred. Typically occurs 30–90 days after exchange of contracts.

Split Loan: A loan divided into two or more portions with different rate types — for example, 60% fixed rate and 40% variable rate. Provides a balance between rate certainty and flexibility.

Stamp Duty (Transfer Duty): A state government tax charged on property purchases. Calculated as a percentage of the property value, varying by state, property value, and buyer type (first home buyers may receive concessions or exemptions).

Tenants in Common: A form of property co-ownership where each owner holds a specified share (which can be unequal). Each owner's share can be willed to any beneficiary — it does not automatically pass to the co-owner.

Title: The legal document that records ownership of a property. The certificate of title shows the registered owner(s), any mortgages (security interests), easements, caveats, and other encumbrances.

Valuation: An assessment of a property's market value, commissioned by the lender as part of the loan approval process. Can be automated (AVM), desktop, or a full physical inspection by a registered valuer.

Variable Rate: An interest rate that can change at any time — typically in response to RBA cash rate changes or the lender's own funding cost movements. Variable rates offer flexibility (no break costs, unlimited extra repayments) but less certainty than fixed rates.
