A home buyer can understand the property they want and still get lost in the language used to finance it. A lender talks about serviceability. A broker mentions LVR. A loan document introduces a comparison rate. Then the valuer, conveyancer,

and settlement process bring another set of terms.

The difficulty is not simply that there are many words to learn. It is that different terms answer different questions. Some affect what you can borrow. Others change what a loan costs, how it is repaid or what happens before the property becomes yours.

This home loan glossary brings together 100 mortgage terms explained in plain Australian English. Rather than arranging them from A to Z, this mortgage glossary groups them by the part of the home loan system they belong to. It is a practical guide to mortgage terminology Australia borrowers may encounter before, during and after settlement.

The People Behind a Home Loan

A home loan involves more people than the person borrowing the money and the lender providing it. Each party has a different role, and those roles become especially important when advice, valuation, legal work and loan comparison enter the process. This first part of the home loan terminology gives you the context before we get into the numbers.

1. Borrower

The person legally responsible for repaying a loan. A borrower signs the loan contract and must meet the agreed-upon repayments and other loan conditions.

2. Co-borrower

Someone who takes out a loan jointly with another borrower. Co-borrowers are generally both responsible for the debt, not simply their individual share of it. This is different from a guarantor, who supports another person’s borrowing without necessarily becoming a co-owner or receiving the loan funds.

3. Lender

The bank, credit union or other credit provider that supplies the money for a home loan. Lenders set their own interest rates, lending policies, assessment methods and product conditions within Australian law and regulatory requirements.

4. Mortgage broker

A finance professional who helps borrowers assess home loan options and apply for financing. A mortgage broker can compare products from the lenders available on their panel rather than offering only one lender’s products. Brokers are generally paid a commission by the lender when a loan settles, although fee arrangements can vary and should be disclosed to the borrower.

5. Guarantor

A person who agrees to support another person’s loan and may become responsible for an agreed amount if the borrower does not meet their obligations. In home lending, a family guarantor may offer part of the equity in their own property as additional security. The exact risks and obligations depend on the guarantee structure.

6. Conveyancer

A licensed professional who handles the legal transfer of property ownership. A conveyancer may review the contract of sale, conduct property searches, prepare documents and coordinate the legal side of settlement. The rules governing who can perform conveyancing work vary across Australian states and territories.

7. Valuer

A qualified professional who estimates the value of a property. A lender may rely on a valuation when deciding how much it is prepared to lend against that property.

The Numbers That Make a Home Loan Work

A mortgage is a balance, a price for borrowing that balance and a structure for paying it back. These common mortgage terms explain those mechanics. Once they are clear, concepts such as offset accounts, refinancing and break costs become much easier to understand.

8. Mortgage

A legal arrangement under which a lender takes an interest in a property as security for a loan. If the borrower seriously fails to meet the loan obligations, the lender may have the right to enforce that security. In everyday conversation, Australians often use “mortgage” to mean the home loan itself.

9. Principal

The amount borrowed, excluding interest and other charges. If you borrow $600,000, the starting principal is $600,000. As principal repayments are made, the amount still owing can fall.

10. Loan term

The period over which a loan is scheduled to be repaid, such as 25 or 30 years. A longer term can reduce required repayments but may increase the total interest paid if the loan takes longer to repay.

11. Loan balance

The amount currently owing on a loan. It changes as repayments are made, interest is charged and, where permitted, further amounts are borrowed or added to the loan.

12. Interest rate

The percentage used to calculate the interest charged on borrowed money. The rate is one of the biggest influences on mortgage cost, but it should not be assessed alone. Fees, loan features and repayment behaviour also affect the amount a borrower ultimately pays.

13. Fixed rate

An interest rate that is locked in for an agreed period, often one to five years. This can provide more certainty over repayments during the fixed period. However, restrictions may apply to extra repayments or early exit, and the rate will not remain fixed forever.

14. Variable rate

An interest rate that can move during the life of the loan. The lender may increase or decrease it in response to funding costs, competition, market conditions and other factors. A variable loan often offers greater repayment flexibility than a fixed loan, but repayments can rise if the rate increases.

15. Split loan

A home loan divided into two or more portions, often with one part on a fixed rate and another on a variable rate. The aim is usually to combine some repayment certainty with some flexibility. Whether that balance is useful depends on the borrower.

16. Comparison rate

A percentage designed to make the cost of certain loans easier to compare by combining the interest rate with most fees and charges into one figure. It is useful, but not a personalised calculation of what every borrower will pay. The advertised comparison rate is based on a prescribed loan amount and term, which may differ from your own loan.

17. Principal and interest repayments

Repayments that cover both the interest charged and part of the amount borrowed. Over time, the principal component helps reduce the outstanding loan balance.

18. Interest-only repayments

Repayments that generally cover the interest charged without requiring scheduled principal repayments during the interest-only period. This can reduce repayments for a time, but the debt itself may not fall during that period. Repayments can rise when principal and interest repayments begin.

19. Repayment frequency

How often scheduled repayments are made, such as weekly, fortnightly or monthly. The options available and the way repayments are calculated depend on the lender and the loan. Borrowers should compare the actual amount paid over a year rather than assuming one frequency automatically saves more.

20. Extra repayments

Payments made above the minimum amount required. Extra repayments can reduce the principal faster and may lower the interest paid over time. Fixed loans and some other products may restrict how much extra can be repaid without cost.

21. Amortisation

The gradual repayment of a loan through scheduled payments over time. With a typical principal and interest home loan, early repayments contain a larger interest component because the balance is higher. As the balance falls, more of each repayment can go towards principal.

How Lenders Work Out What You Can Borrow

Income matters, but it does not determine borrowing power on its own. Lenders look at income, debts, expenses and the ability to keep making repayments under less favourable conditions. This is where some of the most important mortgage terminology Australian borrowers encounter begins to connect.

22. Borrowing capacity

An estimate of how much a lender may be willing to lend based on your financial circumstances and its lending criteria. Income is only one part of the calculation. Existing debts, credit limits, expenses, dependants and the proposed loan can all affect the result.

23. Serviceability

A lender’s assessment of whether you can afford the proposed loan repayments. Serviceability calculations generally consider income, financial commitments and expenses. Different lenders can assess the same borrower differently because their policies and models are not identical.

24. Serviceability buffer

An additional margin used when a lender assesses whether a borrower could continue to afford repayments if interest rates were higher than the actual loan rate. The buffer is an assessment tool. It is not an extra interest rate charged to the borrower.

25. Debt-to-income ratio (DTI)

A measure comparing a borrower’s total debt with their gross annual income. For example, $600,000 of total debt against $100,000 of gross annual income produces a DTI of six. From February 2026, APRA’s macroprudential limit allows ADIs to have up to 20% of new owner-occupier lending and 20% of new investor lending at a DTI of six times or more.

26. Household Expenditure Measure (HEM)

A benchmark that may be used as one input when lenders assess household living expenses. It should not be confused with a borrower’s actual spending. Lenders may consider declared expenses and other information as part of their assessment rather than treating HEM as a universal budget for every household.

27. Living expenses

The ongoing costs of running a household and maintaining a lifestyle, such as groceries, utilities, transport, insurance, education and recreation. Lenders ask about living expenses because money already committed elsewhere affects how much is available for mortgage repayments.

28. Credit score

A numerical indicator derived from information in a person’s credit file. It can help a lender assess credit risk, but it is not the only factor in a home loan decision. Different credit reporting bodies may use different scoring systems.

29. Credit report

A record containing information about a person’s credit history. It may include credit accounts, repayment history, credit enquiries and certain defaults or other credit events. Checking your report can help identify incorrect information before applying for a home loan.

30. Credit enquiry

A record created when a credit provider accesses a credit report in connection with a credit application. One enquiry does not tell the whole story, but multiple applications over a short period may form part of a lender’s assessment.

31. Credit history

The broader record of how a person has used and managed credit over time. A credit history can include the types of credit held, applications made and repayment behaviour. It is one part of the financial picture a lender may consider.

32. Arrears

Repayments that are overdue. A borrower is in arrears when required payments have not been made by the due date. Falling behind can lead to fees, collection activity and more serious consequences if the situation continues.

33. Responsible lending

The legal obligations that apply to certain consumer credit activities in Australia. Broadly, these obligations are intended to prevent unsuitable credit contracts being entered into with consumers. Responsible lending is not the same as a guarantee that every approved loan will remain affordable under every future circumstance.

The Language of Deposits, Equity and LVR

The money you bring to a purchase, the value you already own and the percentage a lender is being asked to finance are related, but they are not interchangeable. This group of first-home buyer terms and broader home loan terminology explains how lenders look at that difference.

34. Deposit

The money a buyer contributes towards the purchase of a property. A larger deposit generally means a smaller loan relative to the property’s value. However, the deposit is not the only cash a buyer may need because purchase costs can sit outside it.

35. Genuine savings

Funds that a borrower has accumulated or held in a way that satisfies a lender’s policy. The definition and required history can vary between lenders. Regular savings are a common example, but borrowers should not assume every source of deposit money will automatically meet a lender’s genuine savings requirements.

36. Gifted funds

Money given to a borrower, often by a family member, without an expectation that it will be repaid. A lender may ask for evidence that the money is genuinely a gift rather than an undisclosed loan. Gifted funds and genuine savings are not always treated as the same thing.

37. Loan-to-value ratio (LVR)

The loan amount expressed as a percentage of the value a lender accepts for the property. If a lender values a property at $800,000 and the loan is $640,000, the LVR is 80%. LVR can affect lending options, pricing and whether LMI is required.

38. Equity

The difference between a property’s value and the debt secured against it. If a property is worth $900,000 and the home loan balance is $600,000, the owner has $300,000 in equity before considering selling or transaction costs.

39. Usable equity

The portion of property equity a lender may allow a borrower to access. Having $300,000 in equity does not necessarily mean all $300,000 can be borrowed against. The amount available can depend on the lender’s maximum acceptable LVR, the property’s value, serviceability and other criteria.

40. Negative equity

A situation where a property’s value is lower than the amount owing against it. For example, if a home is worth $600,000 but the secured debt is $650,000, the owner has negative equity.

41. Lenders Mortgage Insurance (LMI)

Insurance that protects the lender, not the borrower, if a home loan goes into default and the sale of the property does not recover the amount owed. LMI is commonly associated with higher-LVR borrowing and is often a one-off cost, although exact requirements vary by lender and loan.

42. Family guarantee

An arrangement where a family member, commonly a parent, provides limited additional security to support a borrower’s home loan. The guarantor may use part of the equity in their own property. This can involve serious financial risk for the guarantor, so independent legal and financial advice may be appropriate.

43. Deposit bond

A guarantee used in place of some or all of the cash deposit required under a property contract. It does not replace the buyer’s obligation to pay the full purchase price at settlement. Acceptance depends on the contract and seller.

44. Security

An asset over which a lender takes legal rights to support a loan. For a home loan, the property being purchased is commonly used as security. If the borrower fails to meet the loan obligations, the lender may ultimately have rights to enforce that security.

45. Cross-collateralisation

A structure where one or more properties secure multiple loans. This can be useful in some circumstances, but it can also link properties and loans in ways that reduce flexibility when selling, refinancing or restructuring debt.

46. Funds to complete

The money a buyer needs to provide for settlement after accounting for available loan funds and other amounts already paid. It may include the remaining purchase contribution and relevant transaction costs. A buyer can have a deposit and still need additional funds to complete the purchase.

Home Loan Features and Loan Types

A feature is only useful if it changes a loan in a way that suits the borrower. The same applies to loan types. This part of the mortgage dictionary explains some common mortgage terms used to describe how a loan works, who it is designed for and what flexibility it may provide.

47. Offset account

A transaction account linked to a home loan. The account balance is offset against the loan balance when interest is calculated. If a borrower owes $500,000 and keeps $30,000 in a full offset account, interest may be calculated on $470,000 rather than $500,000. Fees, eligibility and offset arrangements vary by product.

48. Redraw facility

A loan feature that may allow a borrower to access eligible extra repayments previously made above the required amount. Redraw is not the same as an offset account. Money in redraw has already been paid into the loan, and access can be subject to the lender’s terms.

49. Owner-occupier loan

A home loan for a property the borrower intends to live in as their home. Lenders may price and assess owner-occupier lending differently from investment lending.

50. Investment loan

A loan used to purchase or hold a property intended primarily for investment rather than as the borrower’s home. Interest rates, lending criteria and tax considerations may differ from owner-occupier borrowing.

51. Construction loan

A loan designed to fund the construction of a property or major building project. Rather than releasing the full loan at once, funds are commonly drawn in stages as construction progresses and agreed milestones are reached.

52. Bridging loan

Short-term finance used to help cover the gap between buying a new property and selling an existing one. Because the borrower may temporarily carry more debt, the timing, interest costs and exit strategy need careful consideration.

53. Low-doc loan

A loan that may allow eligible borrowers to demonstrate income using alternative documentation rather than the standard evidence required for a conventional loan. “Low-doc” does not mean “no assessment”. Lenders still apply eligibility, verification and credit requirements.

54. Non-conforming loan

A loan for a borrower or situation that falls outside the standard lending criteria of mainstream lenders. The reason may relate to credit history, income evidence or another feature of the application. Rates, fees and conditions can differ from standard home loans.

55. Line of credit

A credit facility that allows borrowing up to an approved limit, with interest generally charged on the amount used. Some property owners use a line of credit secured against property, but easy access to funds can also make debt harder to reduce if the facility is not managed carefully.

56. Rate lock

An arrangement that may allow a borrower to secure a fixed interest rate before the loan settles or the fixed-rate period begins. A fee, time limit or other conditions may apply. A rate lock is not available with every fixed-rate loan.

57. Revert rate

The interest rate that applies after a temporary or fixed-rate period ends. A borrower coming off a fixed rate, for example, may move to a variable rate unless another arrangement is made. The new repayment amount can differ materially from the previous one.

58. Loan portability

A feature that may allow an existing home loan to be transferred from one security property to another, subject to the lender’s approval and conditions. Portability does not mean a borrower can automatically move a loan to any new property.

The Fees and Costs Around a Home Loan

The interest rate is not the only number attached to a mortgage or property purchase. Some costs arise when the loan is established, others while it is held, and some when it is changed or closed. These home-buying terms help show where the money can move outside the regular repayment.

59. Application or establishment fee

A fee a lender may charge to process, set up or establish a loan. The name and amount vary by lender. Some loans charge no application fee, which is why costs should be compared across the full loan rather than judged by one fee alone.

60. Annual package fee

A recurring fee charged for some home loan packages. A package may include interest rate discounts or other products and features. The value depends on whether the benefits outweigh the ongoing cost.

61. Valuation fee

A charge associated with assessing the value of a property. Some lenders absorb this cost in certain circumstances, while others may charge the borrower.

62. Discharge fee

A fee that may be charged when a mortgage is discharged, often because the loan has been repaid, refinanced, or the property sold. It is separate from any fixed-rate break cost.

63. Break cost

A cost that may apply when a borrower changes or repays a fixed-rate loan before the fixed period ends. The amount can depend on factors such as market interest rate movements, the remaining fixed period and the amount being repaid.

64. Switching fee

A fee that may apply when changing a loan product or arrangement. The term is used differently across lenders, so borrowers should check what action triggers the fee and whether other costs also apply.

65. Stamp duty or transfer duty

A state or territory tax that may apply when property ownership is transferred. “Stamp duty” remains the familiar term, although “transfer duty” is the formal name used in some jurisdictions. Rates, thresholds and concessions differ across Australia.

66. Conveyancing costs

The professional fees and related expenses involved in handling the legal work for a property transaction. The amount can depend on the service provider, the property and the complexity of the transaction.

67. Mortgage registration fee

A government charge associated with registering a mortgage over a property’s title. The amount varies by state or territory and is separate from the lender’s own fees.

68. Building insurance

Insurance covering the physical structure of a property against specified events. A lender may require evidence of appropriate cover before settlement in some transactions because the property is being used as security for the loan.

Property and Valuation Terms Buyers Often Confuse

A property can have a sale price, a market value, an agent’s appraisal and a lender’s valuation. Those numbers can be similar, but they are not interchangeable. This section covers property terms Australia buyers often encounter alongside the mortgage process.

69. Property valuation

A formal assessment of a property’s value. For lending purposes, a valuation helps the lender assess the property being offered as security and calculate measures such as LVR.

70. Market value

An estimate of the amount a property may reasonably sell for in the open market under normal conditions. Market value is an assessment, not a guaranteed future sale price.

71. Purchase price

The amount the buyer agrees to pay the seller for the property. The purchase price does not automatically become the value a lender uses. If the lender’s valuation is lower, the difference can affect the LVR and the amount the borrower needs to contribute.

72. Bank valuation

A valuation obtained or accepted by a lender for mortgage purposes. Its job is to help the lender assess its security position. It may differ from the purchase price or an agent’s appraisal.

73. Appraisal

An estimate of a property’s likely selling price, commonly provided by a real estate agent. An appraisal is generally used for sales and marketing discussions. It is not the same as a formal valuation prepared for lending or other professional purposes.

74. Contract of sale

The legal agreement setting out the terms of a property transaction between buyer and seller. It can cover the price, deposit, settlement arrangements, inclusions and special conditions. Buyers should obtain appropriate legal advice before committing to a contract.

75. Building and pest inspection

An inspection intended to identify visible building defects, damage and signs of pest activity. The scope and findings depend on the inspection. It is not a guarantee that a property has no hidden problems.

76. Strata title

A form of property ownership commonly used for apartments, units and some townhouses. The owner holds title to an individual lot and shares ownership and responsibility for common property through the relevant owners corporation or body corporate structure.

77. Strata report

A report or records review that can provide information about a strata scheme. Depending on the jurisdiction and report, it may cover finances, levies, insurance, meeting records, disputes and planned works. It can help a buyer investigate obligations that are not visible during a property inspection.

From Application to Settlement

A loan can be discussed, assessed, approved and documented without all of those stages meaning the same thing. These first home buyer terms follow the process from applying for finance to becoming the legal owner of the property.

78. Home loan application

A formal request for finance submitted to a lender. The application usually includes information about the borrowers, income, expenses, debts, assets and the proposed loan. Supporting documents are commonly required.

79. Pre-approval

An indication that a lender may be willing to lend up to a certain amount based on an initial assessment. Pre-approval is not a guarantee that the final loan will be approved. Conditions, expiry periods and terminology vary by lender, and the property itself may still need to be assessed.

80. Conditional approval

An approval that remains subject to specified requirements being met. Those conditions might involve further documents, valuation or verification. Some lenders use “conditional approval” and “pre-approval” in overlapping ways, so the actual conditions matter more than the label.

81. Unconditional approval

Approval given after the lender is satisfied with its required assessment and outstanding conditions. It is a much stronger stage than pre-approval, although the borrower still needs to review and complete the lender’s documentation before settlement.

82. Loan offer

The lender’s formal offer to provide finance on stated terms and conditions. The borrower should review the interest rate, fees, loan features, repayment obligations and other conditions before accepting.

83. Loan contract

The legally binding agreement governing the loan. It sets out matters such as the amount borrowed, repayment obligations, interest and fees, together with the rights and responsibilities of the parties.

84. Finance clause or subject to finance

A condition in a property contract that may allow the buyer time to obtain finance and, depending on its wording and applicable law, certain rights if finance is not obtained. The exact wording matters. Buyers should not assume every “subject to finance” clause provides the same protection.

85. Cooling-off period

A limited period during which a buyer may have a legal right to withdraw from certain property contracts, often subject to conditions or financial consequences. Rules vary by state and territory. Cooling-off rights may also differ for properties bought at auction.

86. Auction

A public sale process where buyers bid for a property, and the highest acceptable bid may secure the purchase. Buying at auction can create particular finance risks because the successful bidder may be entering a binding contract immediately, with different cooling-off rules from a private sale.

87. Exchange of contracts

The point at which the buyer and seller exchange signed property contracts and the agreement becomes binding, subject to the contract and applicable law. The process and terminology can differ between Australian jurisdictions.

88. Settlement

The final stage of the property transaction, when the required funds and legal documents are exchanged and ownership is transferred to the buyer. The home loan funds are typically advanced as part of this process.

First Home Buyer and Government Terms

Government support can change the deposit, savings or ownership pathway available to an eligible buyer. It does not remove the need to meet the rules of the relevant scheme or obtain suitable finance. Because programs and eligibility settings can change, these first home buyer terms should always be checked against current official information.

89. First home buyer

Generally, a person purchasing their first home. The exact definition can differ between grants, schemes and concessions. A person who qualifies as a first home buyer under one program may not automatically qualify under another.

90. First Home Owner Grant (FHOG)

A state or territory grant available to eligible first home buyers under local rules. Eligibility, property requirements and grant amounts differ across Australia. It should not be confused with a federal home loan guarantee or shared equity scheme.

91. Australian Government 5% Deposit Scheme

A federal scheme that helps eligible first home buyers purchase a home with a deposit from 5% without paying LMI, subject to scheme rules and property price caps. From 1 October 2025, the scheme was expanded with uncapped places and no income caps for first-home buyers.

92. First Home Super Saver Scheme (FHSSS)

A federal scheme that allows eligible people to make certain voluntary contributions to superannuation and later apply to release eligible amounts, plus associated earnings, to help purchase a first home. The scheme has detailed contribution, release and eligibility rules. It does not allow a person to withdraw their entire super balance for a home deposit.

93. Help to Buy

An Australian Government shared equity scheme under which eligible buyers purchase a home with a government equity contribution. The government can contribute up to 40% of the purchase price of a new home or 30% of an existing home. Income limits and other eligibility rules apply, with expanded income limits taking effect from 1 July 2026.

94. Shared equity

An arrangement where another party contributes towards the purchase of a property and receives an equity interest in return. This can reduce the amount the buyer needs to borrow, but the other party may share in future changes in the property’s value according to the arrangement.

The Mortgage Terms That Matter After Settlement

Settlement ends the purchase. It does not freeze the mortgage in place. Rates expire, loan balances change, and a borrower’s financial position can look very different several years later. This final part of the mortgage glossary covers common mortgage terms used when an existing loan is reviewed, changed or replaced.

95. Refinancing

Replacing an existing loan with a new one, either with the same lender or a different lender. Borrowers may refinance for a lower rate, different features, debt restructuring or another financial objective. The potential benefit needs to be weighed against switching costs and the terms of the new loan.

96. Repricing

Negotiating a different interest rate on an existing loan without necessarily replacing the loan with a new one. A borrower may ask the current lender to review the rate, particularly if comparable loans are priced more competitively.

97. Discharge of mortgage

The legal process of removing a lender’s registered mortgage from a property’s title. A discharge is commonly required when a property is sold or a loan is refinanced to another lender.

98. Cash-out refinance

Refinancing for more than the amount needed to repay the existing loan, with the borrower receiving or using the additional funds for an approved purpose. The lender will generally assess the purpose, available equity and the borrower’s ability to service the higher debt.

99. Loan top-up

An increase to an existing loan, subject to the lender’s approval. A top-up may allow an eligible borrower to access additional funds without replacing the entire home loan. The higher balance still needs to be affordable and supported by the lender’s assessment.

100. Fixed-rate expiry

The end of a loan’s agreed fixed-interest period. At expiry, the loan may move to a variable revert rate unless another arrangement is made. This is an important point to review the new repayment amount and available options rather than assuming the loan will continue on similar terms.

You Do Not Need to Memorise All 100 Terms

A glossary can tell you what a term means. The more useful question is what that term changes in your own situation.

An LVR can affect one borrower differently from another. An offset account can be valuable for one household and unnecessary for the next. A lender that suits a straightforward application may assess a more complex one differently.

Keep this home loan glossary as a reference when a term appears in a lender conversation, loan document or property purchase. When the language begins to affect how much you can borrow, what the loan costs or which structure suits you, that is the point to look beyond the definition.

Efficient Capital Solutions can help you understand the home loan options available for your circumstances, whether you are buying, refinancing or reviewing an existing mortgage.
